So sánh ReactJs vs Angular

Angular là một framework Javascript được xây dựng bằng Typescript, trong khi Reactjs là một thư viện Javascript và được xây dựng bằng JSX. Angular chủ yếu được sử dụng để xây dựng các ứng dụng cấp doanh nghiệp phức tạp như ứng dụng một trang và ứng dụng web tiến bộ, trong khi React được sử dụng để xây dựng các thành phần giao diện người dùng trong bất kỳ ứng dụng nào có dữ liệu thường xuyên thay đổi. Đường cong học tập của Angular dốc hơn do có quá nhiều chức năng tích hợp trong khi kích thước gói của React nhỏ hơn.

Những đặc điểm này và một số đặc điểm khác biệt khác làm cho Angular và React về cơ bản khác nhau, và do đó, chúng ta cần đặt nền tảng chung để có thể so sánh hai thứ này. Trước tiên, chúng ta hãy tìm hiểu các thông số kỹ thuật với sự trợ giúp của biểu đồ dưới đây.

So, which is better?

All in all, both can be the right frameworks are great for building modern mobile and web applications with component-based architectures. Choose the one that best suits your project functionalities, preferred programming paradigm, project workflows, and the skills of your developers.

React is somewhat choosing an easy way to get the job done since it hasn’t much to do with organizing HTML but instead has the simplest ways to reuse the UI components. While Angular is capable of handling multiple things on its own without depending on any additional help, it may seem tricky at first. However, the benefits foresee the more extended concept and outweigh the time invested.

React is a go-to option for one pizza team since they would want to build an application out of a small learning curve. While building an enterprise-grade application with big development, teams can choose Angular since the bigger learning curve is no bar for them.

Whether it is Angular or React, we are here to help you build highly performant web apps

React is a JavaScript library, whereas Angular is a TypeScript-based JavaScript framework. React uses one-way data binding and virtual DOM trees, whereas Angular uses two-way data binding and real DOM. Moreover, React is faster than Angular as it has a smaller bundle size.

Angular is a full-fledged structural framework based on TypeScript for building mobile and desktop web apps, while React is an open-source library based on JavaScript for creating interactive and complex user interfaces. Angular is mostly used to build complex enterprise-grade apps like single-page apps and progressive web apps.

Angular is better than React if your application is enterprise-grade and you need to incorporate complex functionalities like progressive, single-page, and native web apps. Since it is a full-fledged framework, functions such as data binding, dependency injection, component-based routing, form validation, and project generation can be implemented with Angular packages. In React, this requires additional libraries or modules to be installed.

Moreover, Angular has pre-built material design components. To use them in React requires installing additional library– Material-UI Library & Dependencies. However, React specializes in creating UI components and can be used in any application, including single-page apps.

In terms of performance, bundle size, and backward compatibility, React outperforms Angular. The component-driven architecture of React allows developers to reuse code components, which tends to save cost and time. It also outperforms Angular due to its rendering optimizations and Virtual DOM implementation. Also, React developers can access many pre-built solutions for development.

In comparison to Angular, React is faster and easier to learn. Angular has a steeper learning curve due to several in-built functionalities, so it takes more time initially. React has a shorter learning curve due to its simple structure, use of plain JavaScript, and small package size.

Angular uses TypeScript, a superset of JavaScript. It is an object-oriented, high-level web programming language developed and maintained by Microsoft. JavaScript is a popular scripting language used to create interactive web applications.

When you think about the JavaScript Ecosystem, you’ll almost certainly think of Angular and React, as they’re two of the most popular front-end development frameworks. But how can you pick between angular vs react? Should you base your selection on the project’s specifications first? Or, in the early stages, consider its popularity and ramp-up time.

What’s the difference between Angular and React? For years, there has been a violent rivalry between these two prominent front-end frameworks. So, which option is the best?

Confused about your next job?

Every time front-end programming is required, the Angular vs React debate occurs. The answer relies on a variety of circumstances, and even front-end developers have debated the topic for years.

Angular vs React: Which to Choose for Your Front End in 2024?

Some say comparing Angular and React is like comparing apples to oranges. Angular is a JavaScript framework built using TypeScript, while React is a JavaScript library built using JSX. Add a few libraries to React, and you can turn it into a complete framework. But the resulting stack workflow is still very different from Angular, so the comparability is limited.

On the other hand, both React and Angular have component-based architecture, resulting in both having reusable and modular elements aiming to solve similar front-end problems. And thus, there is a never-ending debate on Angular vs React in the development community.

So, which one is better? This article gives an in-depth comparison of Angular and React based on various factors to help you analyze which is best suited for your project.

Detailed comparison: Angular vs React

Let’s now compare React and Angular in detail.

Popularity: Angular vs React

Both frameworks have gained popularity in discussion forums and the developers’ community. But which is more popular? While looking at popular stats, Angular has 86.7k stars, and React has 203k stars on GitHub. And according to a Statista survey in 2022 on the most used web frameworks worldwide, React secured the second spot while Angular was in the fifth spot.

Angular: Since its initial release as AngularJS in the early 2010s, it gained a lot of popularity, especially for building single-page applications. Thus, it is a mature framework.

In 2016, Angular 2 was released, a complete redesign of AngularJS, with many new features and improvements. Since then, Angular has continued to evolve and improve with new releases and remains a popular choice for building web apps. However, competition from other JS frameworks and libraries like Vue.js (a progressive framework) and React has affected its popularity.

React: React is the clear winner here as it has always maintained more popularity on average than Angular. It gives the advantage of rendering optimizations, virtual DOM, and easy migration between versions. Moreover, it has the simplest ways to reuse the UI components, offering an easy way to get tasks done. All these and more features of React have made it the go-to JS front-end framework for dynamic web applications.

Performance: Angular vs React

Both frameworks have distinct abilities to build high-performing web apps. But which is faster? While React has quite a good reputation for boosting performance, Angular isn’t lagging anywhere in the competition.

Angular: Angular has everything to optimize coding practices and leads to an established level of programming that continually enhances performance. For example, optimizing the digest cycle for your proposed code structure is easier with Angular. While you develop the codebase for further modules, monitoring and optimizing the loop can verify the previously assessed changes.

Also, projects that don’t need two-way data binding can be served with older versions of Angular to reduce complexities to a noticeable extent. Moreover, Angular offers $cacheFactory that works better for memorization and can eventually be used for recalculating the data being calculated later. And in terms of rendering of pages, Angular uses real DOM but has a unique mechanism of change detection combined with zones that makes web apps faster.

Check how we build a highly performant Angular app for the food truck industry.

React: React boasts of a virtual DOM, one of its most sought-after features for application performance. It allows front-end developers to make changes without having to rewrite the full HTML document. This ensures speedier performance by rendering updates faster and refreshing data faster on web pages.

The reusability of components is another aspect of React that gives it a competitive edge. It can be a critical issue when your developers working on different projects are dealing with complex logic and cannot reuse it again in the projects. React can solve this issue by allowing developers to reuse system components.

Reusing React components is also common among designers since it doubles the productivity and optimizes coding practices – starting from the finest components like the checkbox and the button, moving to the wrapper components, and reaching the root components. Such practices ultimately lead to consistent app performance and facilitate code quality and maintenance regardless of the project’s complexity.

Data binding: Angular vs React

The biggest difference between Angular and React lies in state management. React depends more on state management libraries such as Helmet and React Router. Angular has built-in data-binding, whereas Redux library usually augments React to provide unidirectional data flow and work with immutable data. Which is better?

Angular: Angular uses two-way data binding, meaning that the model state changes automatically whenever any interface element changes. This keeps the two layers updated with the same data.

Angular binds the HTML element to the model variable and not just displays it but also changes it in the backend. It helps coordinate the two data models of a framework, which helps create an interactive user interface without the programmer’s intervention of several callbacks and extra efforts.

Two-way data binding is the most efficient technique for fetching data from large ERP-based software like medical software, accounting, and other software that demands highly complex requirements. Thus, Angular’s bidirectional nature makes it easy to build ERP software.

React: It uses one-way data binding, which renders the modifications in the interface model only after the model state has been updated first. And whenever the UI components get changed, the model state remains the same without any changes. This unidirectional data flow gives React developers more control over the web and mobile apps.

React library does not follow the automatic approach to data binding and lets developers fall into the nitty-gritty of complex handling of objects. However, it uses one-way data binding with two-way data binding helpers to manage heavy parsing work and extensive data manipulation.

Code quality and maintainability: Angular vs React

Angular: At Simform, we leverage tools like AngularCLI to scaffold, build, and maintain high-performing Angular applications. Moreover, integrations like Angular Core, Angular Material, etc. have made our Angular project deliveries more effective and code quality better.

AngularCLI reduces the learning curve and also allows Angular developers to predict compilation behavior. It generates smooth builds and reduces the iterating efforts of developers which usually leads to bad code quality in the end.

Here’s a tweet by an Angular expert, Kevin Kreuzer:

We’ve often seen developers dealing with serious maintainability problems whenever combining HTML and JavaScript is difficult due to a lack of modularization. Angular resolves these problems by enabling maintainable JavaScript code. It provides an HTML extension to deal with such problems, and as a result, saves a lot of precious development hours.

React: It has many aspects that not only increase code quality but give an identity that is different from all other web frameworks. For instance, using Display Name string to debug the messages will let you distinguish the components. Moreover, developers can focus on modern JavaScript and worry less about framework-specific code.

Maintaining code quality in React is easy because of the code review practices it allows by providing Linters. It helps in generating identical coding practices among the developers in an organization since Linters follows a strict set of rules that keep the codebase consistent.

React allows developers not to rewrite the same code and get confused between the code review comments. Instead, React has made them develop a code that works among small modules without becoming redundant in practice.

React doesn’t let developers write code in splits and makes it super usable by computer but also makes it intelligible for other developers. Since it facilitates building custom React components, it is easy to render the uncontrolled input fields and recognize the components easily with unique naming conventions.

Server-side rendering: Angular vs React

Angular: With server-side rendering, Angular renders the application by creating a static view before it gets fully interactive. It is up to you how cleverly you use the combination of JSON and client-side caching to increase server-side performance. Nothing beats Angular when it comes to reducing the traffic between client and server.

React: To make your application SEO-friendly, you would need to render the application to the server. React does it with ease with the help of some specific functions. You can do it by calling the RenderToString function instead of calling Render. Unlike other JavaScript frameworks, React is not that rigid a library and offers substantial flexibility.

Alternatively, you can also use renderToStaticMarkup to avoid creating DOM attributes such as data-react-id, which is useful for creating a simple static page generator. The most prominent example of React application is Facebook, with super high-speed rendering and better functions even at a mediocre internet connection.

Testing in Angular vs React

Angular: Testing in a dynamically typed language like JavaScript makes achieving 100% of testing goals difficult. That is why code written in JavaScript has to undergo a strong set of tests. Angular has multiple features, such as isolation of the unit code, and is written with all the concerns keeping testability in mind.

For instance, the in-built Angular feature, i.e., dependency injection, makes it easy to decouple components for testing and mocking.

While Angular provides testing and debugging for an entire app project with a single tool, React requires a set of tools to perform different types of testing.

React: While writing tests, mocking the parts that do not already exist in the testing environments is preferable. Tests can spy on the other parts of the function and predict their interactions with them. It is the mocking of data or functions, and it is quite helpful in avoiding flakiness in data fetching. In a nutshell, tests are very much predictable in React due to the availability of mocking functions.

React executes test suites continuously to run test cases as a part of the development process. It also offers test runners like Mocha, Ava, and Jest that are capable of running tests while already running the development process.

Optimizing the bundle size: Angular vs React

The file that must be downloaded at the initial page loading is a bundle file. The larger the bundle file size, the longer it takes for browsers to load a webpage. Hence, optimizing it as much as possible is crucial, as it can improve or impair an application’s performance.

Angular: Angular applications use a compilation process to run in a browser because a browser does not directly understand its components and templates. The compiler adds understanding between the browser and the code in the bundle file. However, an increase in the bundle file size can affect the loading time and reduce performance.

For faster rendering, Ahead-of-Time (AOT) can be used as a part of the workflow. While it isn’t the default option from Angular, it can always be activated through the CLI by switching to the production mode. AOT converts the Angular HTML and TypeScript code into efficient JavaScript code during the build phase before the browser downloads and runs that code.

React: Bundle file size especially matters for building a large app to run smoothly. And analyzing it is the most important thing when optimizing the application codebase. When you overlook the bundle size with a tech stack like React, you may have to start worrying about it as the app gets larger.

Ultimately, what began with a few components initially becomes a huge file in production if you add new pages and features constantly. Code-splitting and compression can be impactfully used to optimize increasing bundle sizes in React without affecting the app’s performance. For more information on ways to optimize bundle size in React, check out this article on how to optimize the performance of your React app.

Learning curve: Angular vs React

Angular: It is vast and dynamic. Developers may find it challenging to cover many topics in Angular at first, but it is worth giving time in the initial phase to enjoy the ease of development that comes with Angular. It starts from primary elements such as directives, modules, components, services, dependency injections, and more. The learning curve for Angular is comparatively higher than React during the initial phase.

So which is easier? It is ideal to pick the tech stack based on the requirement of your upcoming projects. However, Angular is winning the ground when it comes to solving the toughest of problems in large-scale applications.

React: The most basic and primary things to learn in React are writing components, managing internal states, and how to use props for configuration. Developers may find it a little unusual to write during the initial stages, but since it doesn’t add complexity, it’s a favorable tech stack.

React won’t ask developers to learn and fall into the complexities of learning logical structures (that may be the reason behind increasing React demand in developers), but by learning the basics along with state management and routing library, you are all set to start building the applications.

It is evident that both these technologies have so much to offer in terms of features, a suite of tools, and performance, making it even more confusing for development teams to choose one over the other.

Angular vs React: Which One Should You Use?

Both these web technologies have some unique features and specialties. In the end, choosing between Angular vs React depends on the team and the type of project.

If you overlook a few drawbacks, Angular is the most comprehensive solution for you. On the other hand, React is exceptionally flexible with core advantages like Virtual DOM and adaptability with other frameworks, libraries, and tools.

Initially, React looks very comfortable to ease into. You can immediately start a project with React. But this doesn’t promise that it won’t get more complicated in the future. In addition, you must have knowledge and experience of working with other JavaScript frameworks and tools to harness React’s full potential.

On the contrary, Angular seems more complex. Therefore, a developer needs to focus and dedicate much time to learning because Angular has a steep learning curve. Once that curve is behind you, though, you’ll find Angular is much easier to maintain and expand upon, especially when it comes to large-scale apps and projects.

Most beginners are likely to start with React and eventually move to using Angular.

Quản lý trạng thái trong React và Angular 2

Quản lý trạng thái của một ứng dụng là nhiệm vụ đấy thử thách. Và nó trở thành một thảm họa thực sự khi một vài component có thể sử dụng chung một trạng thái đã được chia sẻ

Quản lý state là một vấn để mà cả React và Angular 2 phải giải quyết để có thể phát triển một ứng dụng client-side ổn định. Và thật thú vị, cả hai framework đều quản lý state theo một cách tương tự nhau, sử dụng một thư viện JS phổ biến là

Redux

Vậy Redux thực sự là gì? Trong một app React đơn giản, bạn có thể kiểm soát trạng thái của app trong các component ở tầng layout. Nhưng giải pháp này sẽ có hiệu quả trong tương lai? Điều này cần phải xem xét. Nếu SPA của bạn phải xử lý các kịch bản luồng dữ liệu phức tạp hay các chuỗi sự kiện phức tạp, bạn cần một phương pháp quản lý tốt hơn, đó là điều Redux đem lại

Redux là một thư viện JavaScript chuẩn cung cấp một kiến trúc cho React. Kiểu kiến trúc đó là gì?

Redux sử dụng luồng dữ liệu một chiều, giúp quản lý trạng thái của ứng dụng rất thuận tiện

Khi bạn bắt đầu xây dựng một ứng dụng React với kiến trúc Redux, bạn cần cung cấp cho app một trạng thái ban đầu, được lưu trong một store. Với Redux, bạn không thay đổi trạng thái ban đầu của app khi trạng thái của app thay đổi . Thay vào đó, chúng ta tạo phiên bản mới trong cùng store. Theo cách này, chúng ta có thể theo theo dấu toàn bộ lịch sử của app React, và có cả cách để quay lại phiên bản đầu tiên. Với Redux, bạn có thể lưu lại mọi thay đổi nhỏ đã xảy ra trong một trạng thái của app. Điều đó thật tuyệt với trong việc debug.

Redux gói toàn bộ ứng dụng vào trong

provider

, đó là một component của kiến trúc Redux mà có thể lắng nghe store và các component được render lại sau mỗi lần thay đổi. Render lại component của app không phải lại một vấn đề với React nữa nhờ có DOM ảo

Ngoài provider và store, Redux còn có 2 kiểu component –

smart



dumb

component. Ý tưởng đằng sau Redux là để xây dựng các component mà có thể lấy và xử lý dữ liệu và các component có thể render sự thay đổi trong layout. Các component được gắn với các action là các đối tượng Javascript chứa dữ liệu được xử lý và render lại.

Cuối cùng, Redux cung cấp

reducer

. Reducer là các chức năng chấp nhận trạng thái hiện tại của một component với một action. Một reducer phải tạo ra một đối tượng trạng thái mới với dựa vào đối tượng action và cập nhật store. Redux có nhiều reducer, và mỗi reducer thay đổi chỉ một vài dữ liệu trong store.

Redux không chỉ là thư viện JavaScript cung cấp một kiến trúc cho app React. Bạn cũng có thể sử dụng MobX và Flux. Redux được khuyến khích cho các app lớn và phức tạp.

Với sự phổ biến của Redux, không có gì ngạc nhiên là bạn có thể sử dụng tốt nó trong các framework JavaScript khác, bao gồm cả Angular. Angular 2 có thể tiếp thu ưu điểm từ luồng dữ liệu vô hướng của Redux, được thực hiện bởi thư viện ngrx/store. Redux hoạt động trong Angular 2 tương tự như với React: sử dụng reducers, một store đơn, các component biểu diễn và các container .

Cả Angular 2 và React thường được sử dụng để xây dựng các app SPA nâng cao, ở mức độ doanh nghiêp với logic phức tạp. Bạn cần phải học cách để quản lý một trạng thái của app trong Redux khi sử dụng React hay Angular.

Summing up

All the above-mentioned JavaScript frameworks enjoy their own fame and are widely used across the world. They are advanced and deliver high performance. The major factor that will affect the choice of JavaScript framework is your business needs and desired app goals.

ReactJS requires you to write less code and perform more. Also, ReactJS is better than AngularJS when it comes to performance.

But AngularJS is a fully featured framework and ReactJS is just a library. AngularJS has a vibrant and large community support while React is just in the inception stage.

On the other hand, Nodejs is mainly created to build scalable and fast network apps. It is simply a JS runtime which is fast and lightweight.

We hope that this helps in the decision you are about to make.

React: To make your application SEO-friendly, you would need to render the application to the server. React does it with ease with the help of some specific functions. You can do it by calling the RenderToString function instead of calling Render. Unlike other JavaScript frameworks, React is not that rigid a library and offers substantial flexibility.

Alternatively, you can also use renderToStaticMarkup to avoid creating DOM attributes such as data-react-id, which is useful for creating a simple static page generator. The most prominent example of React application is Facebook, with super high-speed rendering and better functions even at a mediocre internet connection.

Testing in Angular vs React

Angular: Testing in a dynamically typed language like JavaScript makes achieving 100% of testing goals difficult. That is why code written in JavaScript has to undergo a strong set of tests. Angular has multiple features, such as isolation of the unit code, and is written with all the concerns keeping testability in mind.

For instance, the in-built Angular feature, i.e., dependency injection, makes it easy to decouple components for testing and mocking.

While Angular provides testing and debugging for an entire app project with a single tool, React requires a set of tools to perform different types of testing.

React: While writing tests, mocking the parts that do not already exist in the testing environments is preferable. Tests can spy on the other parts of the function and predict their interactions with them. It is the mocking of data or functions, and it is quite helpful in avoiding flakiness in data fetching. In a nutshell, tests are very much predictable in React due to the availability of mocking functions.

React executes test suites continuously to run test cases as a part of the development process. It also offers test runners like Mocha, Ava, and Jest that are capable of running tests while already running the development process.

Optimizing the bundle size: Angular vs React

The file that must be downloaded at the initial page loading is a bundle file. The larger the bundle file size, the longer it takes for browsers to load a webpage. Hence, optimizing it as much as possible is crucial, as it can improve or impair an application’s performance.

Angular: Angular applications use a compilation process to run in a browser because a browser does not directly understand its components and templates. The compiler adds understanding between the browser and the code in the bundle file. However, an increase in the bundle file size can affect the loading time and reduce performance.

For faster rendering, Ahead-of-Time (AOT) can be used as a part of the workflow. While it isn’t the default option from Angular, it can always be activated through the CLI by switching to the production mode. AOT converts the Angular HTML and TypeScript code into efficient JavaScript code during the build phase before the browser downloads and runs that code.

React: Bundle file size especially matters for building a large app to run smoothly. And analyzing it is the most important thing when optimizing the application codebase. When you overlook the bundle size with a tech stack like React, you may have to start worrying about it as the app gets larger.

Ultimately, what began with a few components initially becomes a huge file in production if you add new pages and features constantly. Code-splitting and compression can be impactfully used to optimize increasing bundle sizes in React without affecting the app’s performance. For more information on ways to optimize bundle size in React, check out this article on how to optimize the performance of your React app.

Learning curve: Angular vs React

Angular: It is vast and dynamic. Developers may find it challenging to cover many topics in Angular at first, but it is worth giving time in the initial phase to enjoy the ease of development that comes with Angular. It starts from primary elements such as directives, modules, components, services, dependency injections, and more. The learning curve for Angular is comparatively higher than React during the initial phase.

So which is easier? It is ideal to pick the tech stack based on the requirement of your upcoming projects. However, Angular is winning the ground when it comes to solving the toughest of problems in large-scale applications.

React: The most basic and primary things to learn in React are writing components, managing internal states, and how to use props for configuration. Developers may find it a little unusual to write during the initial stages, but since it doesn’t add complexity, it’s a favorable tech stack.

React won’t ask developers to learn and fall into the complexities of learning logical structures (that may be the reason behind increasing React demand in developers), but by learning the basics along with state management and routing library, you are all set to start building the applications.

It is evident that both these technologies have so much to offer in terms of features, a suite of tools, and performance, making it even more confusing for development teams to choose one over the other.

Điều hướng với Angular 2 và React

Một app SPA mà không điều hướng đến các trang khác thì không thực sự là một ứng dụng một trang. Với công cụ điều hướng phù hợp, app có thể chuyển đến mọi trang, sử dụng các route con, tận dụng khả năng của lazy loading, và quản lý các truy cập cho từng trang, ngăn chặn ngay lập tức user truy cập vào một trang chưa được authenticate.

Bởi vì routing là một tính năng cơ bản cho một ứng dụng SPA nâng cao, Angular 2 và React phải đưa ra một vài cách để quản lý route. Nhưng thực sự là không có framework nào có sẵn khả năng xử lý route trong thư viện core, mà bạn phải cái đặt một vài thư viện bổ sung là Angular Router và React Router. Nhưng route này hoạt động đơn giản – chúng chỉ là tọa một đường dẫn cụ thể như một đầu vào và tải component liên kết với đường dẫn đó.

Tạo các route trong một app React đơn giản hơn so với Angular 2. Để bắt đầu sử dụng route trong app React, bạn cần cài đặt

react-router

bằng NPM, sau đó import thư viện route vào trong main.js, client.js hay các file JavaScript khác.


import React from 'react'; import ReactDOM from 'react-dom'; import { Router, Route, IndexRoute, browserHistory } from 'react-router'; import MainLayout from './main-layout'; import ContactUs from './contact-us'; import Users from './users'; import NotFound from './not-found'; const app = document.querySelector('#react-app'); ReactDOM.render( , app);

Đó là một cách sử dụng đơn giản của route trong app React. Thay vì render trực tiếp như vậy, bạn có thể sử dụng Router, sẽ đóng gói tất cả route , bao gồm cả index route. Sau đó, bạn chỉ cần chỉ ra đường dẫn và một component tương ứng cho mỗi route và thực hiện các link điều hướng trong main page để user có thể chuyển qua lại giữa các page.

Với Angular 2, route khá khác so với React. Chúng ta có thể cấu hình route lúc đầu và chỉ ra layoute cơ sở mà route sẽ được tải. Layout này nằm trong index.html file, chúng ta cần thêm tag ‘base’ và thẻ head để Angular Router biết chỗ tải route.

Trong React, bạn có thể cấu hình route trong cùng file, nhưng Angular thích hợp với cách chia theo module hơn.


//separate file app.routing.ts import { Routes, RouterModule } from '@angular/router'; import { MainComponent } from './main/home.component'; import { UsersComponent } from './users/users.component'; import { AboutUserComponent } from './users/about-user.component'; import { ContactUsComponent } from './contact-us/contact-us.component'; import { NotFoundComponent } from './not-found/not-found.component'; const appRoutes: Routes = [ { path: '', component: MainComponent }, { path: 'users', component: UsersComponent }, { path: 'users/:user', component: AboutUserComponent }, { path: 'contact-us', component: ContactUsComponent }, { path: '**', component: NotFoundComponent } ];

Cả hai framework đều yêu cầu module cho route. Angular yêu cầu sử dụng một file tách riêng cho route và cài đặt trước khi bạn thêm vào một module trong app. React làm việc tốt khi bạn chỉ ra route trong file main JS, vì vậy có thể không cần tạo các file bổ sung cho route.

Angular là gì?

Angular là front-end development framework – mã nguồn mở do Google cung cấp. (ReactJS là do ông lớn Facebook cung cấp). Nó là một phần của MEAN stack; có độ tương thích với một số lượng lớn các trình soạn thảo mã. Đặc biệt hơn, nó còn được biết đến nhờ chức năng tạo các trang web; và ứng dụng web động.

Hai front-end development frameworks được sử dụng bởi các thương hiệu có uy tín khác nhau, bao gồm: React vs Angular

Why Should You Use React?

React is exceedingly lightweight, and it’s faster to learn and get things started with, too. In addition, React allows third-party libraries for use during the development process. It also sports a bidirectional data binding process.

Here are some of the top reasons to start using React.

Easy to Learn

React is comparatively easy to learn and implement, so businesses can quickly hit the ground running. The library is SEO-friendly, and it focuses on rendering speed. Companies that use React can typically expect to see a reduction in load time and a higher rank in search engine results.

Reduced Coding

In React, you can have similar code for both the client-side and server-side of an application. Hence, any website with React has high-speed advantages, making it attractive to crawlers, users, and developers alike.

Moreover, it’s easy to test because React can treat views as functions of a specific state.

Facebook Support

An excellent advantage of React is Facebook itself. A group of individual developers, particular communities, and Facebook itself maintains this framework.

Like Google for Angular, Facebook feels optimistic about React. And because of its great accessibility and usages, React has a wider range of possibilities for new developers to learn this framework quickly and take that first successful step toward app development.

Why Should You Use Angular?

In Angular, everything happens under the same hood. It offers an ecosystem that allows you to create your application effortlessly. Features like templating, two-way binding, RESTful API modularization, Ajax handling, dependency injection, and many more features make your application development accessible and compact.

Though we’ll have a detailed discussion about Angular features in the features section, here are some of the main reasons you should consider picking Angular.

Google Support

The primary advantage of using Angular is Google. Google has long-term support for Angular. That’s why it’s still scaling up the Angular ecosystem.

All Google apps that you encounter use the Angular framework. As confidence in the framework grows, other developers also find opportunities to learn from seasoned Angular professionals.

Detailed Documentation

Angular provides detailed documentation to guide developers. Rather than forcing you to search in different places, you can find all the explanations you need in the same place. In most cases, absorbing comprehensive documentation is the most efficient way to learn a language (besides practicing with code).

Reduced Coding

Angular promises less time spent coding and helps to create blazingly fast apps. TypeScript helps Angular efficiently identify errors and eliminate them in an earlier phase of the development cycle than many other frameworks.

Angular frees you from worrying about whether something’s a component, service, or any other code type, as it organizes them into neat, separate boxes. It then introduces them as modules. These modules make it easy to structure your application’s functionality, separating elements into features and reusable pieces.

Moreover, Angular offers cleaner coding overall. That said, cleaner coding doesn’t ensure better readability. It merely means a more contradiction-free environment.

AngularReact: A quick comparison

React and Angular are popular JS frameworks for building complex and interactive web applications. While they share several similarities, some distinct characteristics make them fundamentally different. Let’s compare the two frameworks briefly before discussing the technical aspects in detail.

Angular React

Ưu và nhược điểm thư viện Reactjs

Ưu điểm

  • Reactjs nổi bật với hiệu suất cao: Tạo ra các DOM ảo giúp cải thiện hiệu suất cho quy trình vận hành. Tùy vào tình trạng, Reactjs tính toán và linh động trong việc cập nhật các thay đổi.
  • Viết các đoạn code JS dễ dàng: Với cú pháp đặc biệt là JSX (Javascript mở rộng) cho phép pha trộn giữa code HTML và Javascript. Đây cũng là một đặc điểm thú vị của Reactjs (điểm bị giới hạn của Angular).
  • Render tầng server: Nói một cách ngắn gọn, ReactJS đã tối ưu hóa việc render ở ngoài trình duyệt sử dụng DOM; tạo hiệu suất ổn định cho các vấn đề tối ưu SEO và thời gian tải trang.
  • Đơn giản và không quá khó khăn trong công tác bảo trì, sửa lỗi, cập nhật hơn nhiều so với Angular

Nhược điểm

Nhược điểm chính của reactjs đó là:

  • Reactjs có bị giới hạn: Do Reactjs không phải là một MVC framework như những framework khác. Render là phần View là chức năng chính, ngoài ra sẽ bị giới hạn khi hoàn toàn không có phần Model và Controller.
  • React khá nặng khi đặt trong phạm vi so sánh với các framework khác
  • Nếu Javascript dễ học và tiếp cận, Angular thuộc tầm trung thì React lại khó tiếp cận với người mới

Tăng trưởng phổ biến : Angular JS so với React JS

Angular và React đều đã trở nên phổ biến trên các diễn đàn thảo luận và trong cộng đồng các nhà phát triển. Trong khi xem xét số liệu thống kê của nền tảng phổ biến nhất, Angular có 56.586 sao và Reactjs có 142.606 sao.

Tuy nhiên, Reactjs là một thư viện chống lại một khuôn khổ chính thức như Angular. Ngược lại, Angular luôn duy trì một con số trung bình ở mức cao về số sao so với Reactjs framework thư viện. Lý do đằng sau số lượng sao nhiều hơn và ít vấn đề hơn trong Reactjs là do Reactjs được phát hành sớm.

Angular vs React vs Vue: Which Framework to Learn in 2022
Angular vs React vs Vue: Which Framework to Learn in 2022

What is React?

React is an open-source JavaScript library for front-end development to build UI components. Its component-based architecture and declarative views let developers create interactive and complex UIs easily. Developers can build fast and scalable apps for all platforms with its “learn once, write anywhere” principle. It is managed by Facebook’s React team and a vast development community.

Here are the distinctive features of React that set it apart from Angular:

  • Declarative views
  • JSX advantage
  • Virtual DOM
  • One-way data binding
  • Building blocks flexibility

Advantages of React

Let’s take a look at some benefits of React:

  • Reusable and more predictable code
  • Easier debugging with declarative views
  • Faster development time
  • Enhanced developer productivity
  • Easy migration between different versions
  • Support for mobile app development with React Native
  • Faster updates with both server-side and front-end support
  • Improved load time and performance with efficiently built UI
  • Integration with third-party libraries

What is React?

React, a JavaScript library used by Facebook was open-sourced in 2013. This framework popularised a web development concept known as component-based architecture, which has several benefits, including:

Components that are modular and coherent, making them highly reusable and contributing to a faster development time.

It’s used in mobile development since it allows developers to reuse the logical section of an app while simply changing the view.

Easy maintenance and improvement due to self-contained components.

React immediately swept the market, overtaking most of the frameworks available at the time, including AngularJS. As a result of the community’s passion for component-based architecture, Google improved their JavaScript framework in 2016 and named it Angular2.

Angular vs React: An In-depth Comparison

Now that you have a good handle on what these two JavaScript children can do, let’s start by taking a look at a side-by-side comparison of Angular vs React.

Parameters Angular React
Type Full-fledged framework JavaScript library
DOM Type Real DOM Virtual DOM
Data binding Bidirectional data binding Unidirectional data binding
Written in Typescript JavaScript
Templates JSX + J% (ES5/ES6) HTML + TypeScript
Abstraction Medium Strong
JavaScript library inclusion in source code Not possible Doable
Model MVC model Virtual DOM
Testing and debugging Complete solution within a single tool Needs an additional set of tools
Freedom Limited Allows a choice of libraries, architecture, and tools

To make things even more clear, in the next sections, we’ll delve into 12 key topics about them.

Similarities

The similarities between Angular and React include:

  • Architecture: Angular and React both have component-based architecture. These components are reusable within other components, making them endlessly recyclable. Notably, a component is a piece of a UI. For instance, the components could be a login dialog box with text, a password field, or a login button.
  • Open source: Both are open source. As a result, React and Angular have large developer communities that regularly enrich the resources.
  • Popular: Developers mostly use both of these technologies to build Single Page Applications. That asserts that you can make single-page applications for faster and better digital solutions.
  • Development environment: Angular and React are used to develop the frontend of a mobile or web application.
  • Rendering: Angular and React provide efficient client-side and server-side rendering.
  • Performance: Angular and React offer similar performance. The difference mostly depends on the user’s perspective.
  • Easy to update: Angular and React both offer easy updating. While Angular uses CLI, React depends on external libraries.

Usefulness

Both Angular and React are beneficial to frontend developers, which is no surprise when considering their respective specialties. Both small- and large-scale apps benefit from their features and flexibility, allowing developers to help their creations reach their full potential.

Here are some of the ways they’re each used.

Angular

As it’s highly effective in cross-platform app development, businesses prefer Angular for building cross-platform apps to reduce expenses. But at the same time, Angular is a very complex platform. Therefore, it requires elevated effort and experience to master it.

So, when you opt to build your project with Angular, veterans will surely reach for it. The framework also offers several advantages that result in faster and more efficient web apps.

With “differential loading” in Angular, a browser can load less code and polyfills to speed things up. The newest version of the framework lets you create two types of code bundles — one for modern browsers and another for older ones.

React provides a built-in advanced Dependency Injection service, which is excellent for resolving productivity factors and speeding up the development process. As a result, users enjoy a more streamlined experience with improved software design functionality.

When you create a large app, code maintainability becomes an important issue. In Angular, it’s a lot hassle-free. When upgrading from one version to another, developers don’t need to worry about compatibility because Angular automatically updates all the related packages, including HTTP, Angular material, and Routing.

Angular’s AOT compiler converts Typescript and HTML code into JavaScript at the time of build. Thus, it’s already compiled before the browser loads the code, resulting in a faster render.

IVY rendering in Angular translates the components and templates to JavaScript code. Its renderer’s tree-shaking technique is unique — it eliminates unused code, so the browser loads a page quicker.

React

React is simple. You can start learning and creating a project within a much shorter time than other platforms. Because you’ll be using raw JavaScript, you’ll have access to the wealth of JavaScript knowledge already compiled on the web.

What’s more, the JSX allows combining HTML and JavaScript in your code. That makes life trouble-free for developers.

As we know, React has server-side rendering. That’s why it’s SEO-friendly — it can deal with most search engines with ease.

Generally, client-side rendering only sends empty HTML code to a browser, while server-side rendering sends the HTML codes and contents to the browser. After that, a browser can easily index it and rank it higher in search results.

React code is stable because it has a downward data flow. Any change in the child components never affects its mother components. This helps the developers to debug with ease.

Features

React and Angular both offer a wide range of features. Some of them are similar, and some are unique. Let’s discuss some of the most significant features of Angular vs React with a comprehensive description.

Angular

Most of the time, the larger a framework, the better it performs. And being a complete framework, Angular offers a whole lot of features.

Here are just a few:

  • Built on TypeScript: Angular is built on top of TypeScript, and Typescript is a superset of JavaScript. To catch errors during developing a mega application and identifying bugs, TypeScript portrays a beneficial purpose. More interestingly, you can directly debug typescript codes in a web browser.
  • Ajax support: Angular has built-in support for Ajax and HTTP, allowing users to connect and communicate with the backend services and boosting performance. In addition, Ajax reduces the response time for both ends’ requests.
  • Component-based architecture: Angular initially started with MVC Model View Controller (MVC) architecture but later shifted to component-based architecture. As a result, you can now divide all applications into completely independent logical and functional components while still testing and running all the application pieces individually.
  • Angular CLI: The Angular Command Line Interface (CLI) is one of the most notable Angular features that developers praise. It automates the whole development process utilizing app initialization and app configuration. It also lets you preview your application with LiveReload support.
  • Readability: Another aspect of the Angular framework is improved readability. Most new developers easily adapt to reading code in Angular. Moreover, its accessibility makes it much easier for the developers to interact with the framework.
  • Easy to maintain: Last but not least, Angular offers superior ease of maintenance. It helps to replace decoupled components with improved ones, which generates clean, easy-to-maintain code and updates.
React

Now let’s take a look at React’s top features:

  • Declarative UI: The React engine uses HTML to compose the application UI. HTML is lighter and less complicated than Java. Consequently, the workflow stays uninterrupted, and Angular itself can determine the program flow rather than you spending your valuable time planning for it.
  • Maneuverability: React offers a simple UI design and provides numerous extensions to provide total support for the application architecture. Likewise, the React native, an inherited framework from React, is commonly known for building cross-platform mobile applications.
  • Clean abstraction: React doesn’t bother the user with its complex internal functions. Internal processes like Digest cycles are not mandatory for the users to learn and understand. As a result, React delivers clear architecture as Flux instead of architectures like MVC/MVVM.
  • Virtual DOMS: React provides a virtual DOM that copies the existing DOM and maintains the cache memory, saving you the effort of re-rendering the DOM trees, again and again, each time you update the HTML code. In other words, if you change any state of a component, the Virtual DOM only changes that particular object in the real DOM.
  • Reusable components: React provides an independent component-based structure. All your React components can also be recycled in other parts of the application because of this reusability.
  • Cross-platform functionalities: Another surprising outcome of React is the spin-off framework called React Native, created for cross-platform mobile application development. In addition, it uses React.js for dedicated mobile application development.

Frameworks

Angular is a full-fledged framework, while React is a JavaScript library. Therefore, React has to be paired with a framework to build fast, beautiful, and compatible UI.

Here are some of the React-based frameworks used by developers:

  • Material UI
  • Ant Design
  • Redux
  • React Bootstrap
  • Atomize

Learning Curve

Learning frameworks like Angular or JavaScript libraries like React can take time and effort. Unfortunately, the process is not similarly smooth for every technology.

To that end, let’s have a brief discussion about the learning curve of Angular vs React.

Angular

The learning curve of a framework depends on its versatility, size, and nature of the framework. If you see a steep learning curve, it’s challenging to learn a language or framework.

The learning curve of Angular is steep because of its enormous structure and dynamics. Therefore, pursuing a wide range of conceptions and relevant codes can be difficult for a beginner.

To learn Angular, you also have to learn TypeScript. Typescript is a superset of JavaScript, and some of its syntaxes are exclusive to Angular and aren’t found in other frameworks.

Google has developed Angular and managed it since its inception. They typically release updates to the framework roughly biannually. Because the release dates aren’t always spaced exactly six months apart, it’s difficult for a developer to keep track of the updates and incorporate them into their ecosystems on time.

In addition, learning Angular features such as dependency injection can be trickier for a developer who has already worked with an alternative. That’s because Angular utilizes them differently.

React

React, on the other hand, is comparatively lightweight and easy to get into. It doesn’t require mastering JavaScript. If you already have intermediate-level experience with the language, you’ll be fine. React also natively includes features like dependency injection, which will reduce the learning time for a new learner.

However, it also has unique features and processes you’ll need to understand and master, such as internal state management and components. Though React may seem simpler to learn than Angular, you’ll need to be more comfortable adapting to new technologies.

While it may take less time considering the complexity of the technology, React still needs dedicated effort to master.

Dependency Injection (DI)

Dependency injection is a pattern of design in which a class will ask for permission externally rather than creating itself. For instance, a computer class may need a “processor” class. The processor class, in that case, is the “dependency.”

Angular

Angular supports dependency injection accommodating flexibility in both testing and debugging. Another great use of dependency injection is the reusability of a class. For example, you can use different types of “processor” in “Computer” to get different computers. Thus, you don’t have to change any code in the Computer class.

Here’s an Angular DI code example:


import { Injectable } from '@angular/core'; @Injectable({ providedIn: 'root', }) export class HeroService { constructor() { } }

React

React has the built-in facility for dependency injection in JSX. DI in React takes place through props and children.

Here’s an example:


const name = 'Josh Perez'; const element =

Hello, {name}

; ReactDOM.render( element, document.getElementById('root') );

Data Binding

Data binding is the process of making a connection between the UI and the displayed data. Though the primary purpose is similar across the board, data binding can function differently in different frameworks.

For instance, you can choose fonts and colors in Microsoft Word and Excel’s “Text Formatting” feature. In the UI, changing the font will show you the output with the selected font. That indicates the establishment of a data connection.

Notably, both Angular and React employ two different kinds of data binding.

What’s more, there’s a significant number of differences between these two.

Angular

Angular uses two-way data binding, also known as bidirectional data binding. This means that if you change something in the UI, it also reflates at the other end in a component class.

However, in technical terms, it’s a comparatively slower process.

React

React, on the other hand, primarily uses unidirectional data binding. A unidirectional data binding indicates a one-way parent-to-child data flow. Therefore, you can’t trace it backward.

In addition, there are a few conditions that maintain the unidirectional data-binding:

  • Component to View: Any change in the component will cause a shift in the view.
  • View to Component: Any change in the view (UI) will cause a shift in the data component.

React one-way data binding (image source: Slideshare)

React one-way data binding explained with directional graph)

This one-way data binding process helps you to write error-free code. It also offers effortless debugging as you have greater control over your data.

However, you can also implement two-way data binding in React if you wish, applying a “change” event on one of your components.

State Management

State management is vital in large applications. That said, it’s not always easy to maintain the state of UI components like text fields, radio buttons, and the like.

Let’s take a look at how state management is handled by Angular vs React.

Angular

In Angular, NGRX is a state management library, which permits the use of reactive state management.

NGRX tends to follow FLUX/REDUX. The advantage NGRX provides is that it stores all the states in a single tree, allowing you to access all the forms from anywhere in an application.

React

In React, every individual React component can have a state, so it’s necessary to manage the states of these components separately. Otherwise, in large-scale applications, a developer may face more bugs and errors than they would otherwise.

Generally, REDUX works as a state management library for React. Another one is Recoil, which is the simplest, most lightweight option. But if you have a good understanding of React, you can use Hooks as the essential state management tool, even without an additional library.

Essential Tools

If you want to start developing with React or Angular, you need to have the essentials for editing, project setup, rendering, and testing. Here are a few tools Angular and React developers use commonly.

Angular

Angular’s tools include:

  • Code editing: Angular is compatible with a variety of code editors. Such as VS Code, Sublime Text, Aptana, etc.
  • Project setup: Setting up a project is very easy with Angular CLI (command line interface).
  • Server-side rendering: Angular Universal does the server-side rendering in Angular.
  • Testing: Jasmine, Protractor, and Karma are widely used for testing an Angular project.
React

React’s tools include:

  • Code editing: VS Code, Sublime Text, and Atom are popular options for React coding.
  • Project setup: Create React apps (CLI) is used to set up a project in React.
  • Server-side rendering: React uses the Next.js framework for server-side rendering.
  • Testing: Jest is well known for testing React apps. Enzyme is another testing utility designed to help React developers check their code.

Performance

In this section, we compare the performance between Angular vs React with execution time for different processes. This gives us a clear idea of how each of these technologies will perform.

Action Angular React
Loading 10ms 7 ms
Scripting 173 ms 102 ms
Rendering 3 ms 6 ms
Painting 4 ms
System 73 129
Idol 3034 3042
Total 3295 3289

Popularity

Now, after all the discussions and explanations above, you may be curious to find out the popularity of Angular vs React among developers.

Most developers find it challenging to pick between these two because of their individuality and conventional performance over the years. However, if we look at the analyzed data of usage percentage, we can get some real idea about the popularity between the two.

Stack Overflow

According to StackOverflow, around 40.14% of 67k respondents in 2021 chose React, while 22.96% kept their hands on Angular.

The data can mislead you to decide unless we dig deep into it. Notably, more questions were tagged for Angular compared to React.

Developers face more complexity with Angular’s ecosystem. And most beginner developers want to start stress-free.

But on the other hand, if a framework’s developer’s community is large and active, it’s arguably easier and less time-consuming to find solutions to any problems that may arise. That’s why many developers choose to depend on the availability of resources rather than on features alone.

GitHub

On GitHub, React has 175k stars on its repository, whereas, for Angular, the number is only 76.5k. Accordingly, GitHub users are likewise interested in React rather than Angular.

We can assume further analysis of the numbers of NPM manager downloads. It seems like React is leading the chart over Angular, and the number is continuously rising every day.

Community

As we already know, Facebook is the creator of React, and Google’s developers built Angular. Support from these two giants is another reason each has gained popularity more quickly than other frameworks. Since their birth, the developer community has done — and continues to do — an exceptional job of updating both React and Angular.

As you might expect, both have large, thriving communities with many active users. Impressive ratings in GitHub and questions tagged in StackOverflow further indicate that.

AngularReact: A quick comparison

React and Angular are popular JS frameworks for building complex and interactive web applications. While they share several similarities, some distinct characteristics make them fundamentally different. Let’s compare the two frameworks briefly before discussing the technical aspects in detail.

Angular React
Type Full-fledged structural framework JavaScript-based library
Purpose Develop dynamic web apps Build interactive UI components
Language TypeScript JavaScript (JSX script)
Developed and maintained by Meta and community
Front-end development approach Extends the functionality of HTML, prefers client-side rendering Uses XML-like syntax called JSX, slight preference for server-side rendering

React và Angular 2 trong khái niệm kiến trúc dựa theo component

Tất cả code của một ứng dụng single-page có thể được gói gọn trong 3 files – index.html, index.css và index.js. Nhưng cách tiếp cận này không cho phép chúng ta mở rộng một SPA. Thay vào đó, chúng ta nên chia nhỏ một SPA thành các phần có nghĩa hay còn gọi là

component

– header, thanh điều hướng, bố cục chính, sidebar, … Sử dụng các component độc lập là cách thích hợp để xây dựng các app SPA hiện đại. Mỗi component sẽ bao gồm markup độc lập, một stylesheet và các Javascript file. Vậy Angular 2 và React đã thực hiện theo kiến trúc dựa vào component như thế nào?

Dưới đây là một ví dụ cách mà ta tạo một component trong React:


import React from "react"; class NewComponent extends React.Component { constructor() { super(); this.state = { component: "New Component!" }; } render() { return(

This is My { this.state.component }

) }; };

Đầu tiên, ta phải import React từ thư viện core để component của ta có thể kế thừa từ React.Component. Trong hàm render, component phải trả về một vài markup JSX.

Một component Angular 2 sẽ khác so với component React:


import { Component } from "@angular/core"; @Component({ selector: "ng2-app", template: `

NG2 {{ title }}

NG2 App

`, css: [` .class { background-color: lightgreen; color: white; } `] }) export class AppComponent { title = 'Application'; }

Với Angular, bạn có thể chèn template và style trực tiếp vào component – mặc dù điều này không được khuyên dùng nếu không phải template và stykle chỉ có vài dòng code. Trong thực tế, component của Angular 2 app không chứa layout và stylesheet. Bạn nên chia mỗi component thành 3 phần: xử lý logic, layout và styles. Do đó, component sẽ giống như:


import { Component } from "@angular/core"; @Component({ selector: "ng-app", templateUrl: "ng-app/ng-app.template.html", styleUrls: [ "ng-app/ng-app.component.css" ] }) export class AppComponent { title = "Application"; }

Cách thực thi của các component sẽ cho ta thấy vài điểm khác biệt giữa Angular 2 và React. Layout của một React component luôn được đặt cùng file với component logic, trong khi các component của Angular 2 cho phép bạn tách logic từ layout.

Cả Angular 2 và React đều quản lý một component khá hiệu quả. Nhưng khi bạn tạo nhiều component cho app, thì một app nên được chia tách thành các đơn vị nhỏ có ý nghĩa chưa logic cụ thể.

Với cả Angular 2 và React, bạn muốn tạo một component chính để giữ tất cả các phần của app. Điều đó rất dễ dàng với cả 2 framework bằng cách sử dụng đặc tính import/ export của ES 6. React quản lý nhiều component theo cách:


import React from "react"; import Header from "./Header"; import Section from "./Section"; import Footer from "./Footer"; class NewComponent extends React.Component { //some business logic goes here render() { return( ) }; };

Bạn sẽ có thể export Header, Footer, Section component từ các file liên quan. Mỗi component con có thể chứa các component con khác. VD, một Header có thể có một Title, và một Section có thể chứa vài component Article.

Angular làm việc đó khá đơn giản tương tự như React. Một App component Angular có thể import một component con và sau đó được chèn vào layout:


import { Component } from "@angular/core"; import { LaptopComponent } from "./laptops/laptop.component"; @Component({ selector: "ng-app", template: `
<br /> {{ title }}<br />
` }) export class AppComponent { title="Application"; }

Với Angular, bạn sẽ phải thực hiện nhiều bước: tất cả các component nhỏ hơn phải được thêm vào file module. Cụ thể , bạn cần phải thêm component Laptop vào @NgModule bên cạnh các component khác


import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { LaptopsComponent } from './laptops/laptop.component'; import { LaptopPartsComponent } from './laptops/laptop-parts.component'; @NgModule({ imports: [ ], declarations: [ AppComponent, LaptopsComponent, LaptopPartsComponent ], bootstrap: [ AppComponent ] }) export class AppModule {}

Đó là một vài sự khác nhau giữa React và Angular trong khái niệm về kiến trúc dựa theo component. Tổng kết, chúng ta có một vài thông tin sau:

  • Angular 2 và React cùng cho phép xây dựng ứng dụng từ các component độc lập riêng rẽ.
  • Cả hai framework khuyến khích chia nhỏ các component phức tạp thành các đơn vị nhỏ hơn.
  • Angular 2 khuyến khích tách các template phức tạp từ component logic, React thì ngươc lại, lưu các template và component logic trong cùng file.
  • Angular 2 sử dụng stylesheet dựa theo component và tách chúng trong các file khác; React không cung cấp cách thức để quản lý CSS stylesheets.

FAQs

Q.1: How is React different from Angular?

Ans: React is a JavaScript library, whereas Angular is a JavaScript framework built on TypeScript. The virtual DOM and one-way data binding are used by React.js, but the real DOM and two-way data binding are used by Angular. There’s also a speed difference (React is faster) and a difference in bundle size (React’s is smaller) (React works a bit faster).

Q.2: Is Angular better than React?

Ans: Because of its virtual DOM implementation and rendering optimizations, React outperforms Angular. It’s also simple to switch between React versions; unlike Angular, you don’t have to install updates one by one. Finally, using React, developers have access to a wide range of pre-built solutions.

Q.3: Can I learn Angular if I know React?

Ans: Yes, knowing how to react is beneficial, but you should not stop there; instead, strive to master it. Of course, you can accomplish almost anything with React that you can do with Angular (perhaps even more), but as a software developer, I believe you should master Angular.

Q.4: Why is React faster than Angular?

Ans: React.js apps make use of a virtual DOM, which allows developers to make changes without having to rewrite the full HTML document. It ensures speedier performance by rendering updates faster.

In this article, we will learn about React js & angular, along with discussing the significant distinction that differentiates Angular from React js.

React.js: React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It’s ‘V’ in MVC. ReactJS is an open-source, component-based front-end library responsible only for the view layer of the application. It is maintained by Facebook. React uses a declarative paradigm that makes it easier to reason about your application and aims to be both efficient and flexible. It designs simple views for each state in your application, and React will efficiently update and render just the right component when your data changes. The declarative view makes your code more predictable and easier to debug.

Features of React js:

  • Scalability: It is reasonable for enormous scale applications because of its adaptable structure and scalability.
  • Rich JavaScript Library: Developers from everywhere throughout the world are placing in exertion to include significantly more features.
  • Code Reusability: It enables the developers to reuse the code components of different levels while working on the project.

Example: This example demonstrates the simple React js syntax.

Angular vs React

Basis of Distinction Angular React
Purpose Full-featured Framework – provides a strong opinion on how your application should be designed, as well as a number of tiny libraries that aid in the development of complex applications. The library is only concerned with UI components. MVC design requires Flux to implement, but it provides you more flexibility in how you wish to organise your code.
Data binding Supports both one way and two way data binding ,two-way data binding means that if we modify the UI input, the model state will change, and vice versa. One-way data binding means that a UI element can’t affect a component’s state.
Language TypeScript is a statically typed language that is a superset of JavaScript. TypeScript can write JavaScript XML (JSX), although it isn’t included by default.
UI Components Material Design Components – Angular includes a number of material design components that make UI configuration a breeze. Material-UI Library & Dependencies – Community-developed UI tools provide a wide range of UI components.
Dependency Injection Dependency injection is supported, allowing for separate life cycles for different stores. React does not fully enable dependency injection because each component has its own global state.
DOM Incremental DOM – when a new DOM is created, it compares it to the previous one and applies the differences to the “actual” DOM, only allocating memory if necessary. Virtual DOM – anytime the DOM changes, a new virtual DOM is created, compared to the previous one, and only the differences are modified in the “real” DOM.

Disadvantages of Angular

The followings are some disadvantages and issues with utilising Angular:

  • For newbies, an angular feature can be perplexing.
  • There isn’t a clear manual or comprehensive, all-encompassing documentation.
  • The learning curve is steep.
  • Limited Routing makes it difficult to debug scopes.
  • When pages have interactive components, Angular can become slow.
  • Integration with third parties is extremely tough.
  • Several complications may arise when upgrading from earlier versions to newer versions.

Difference between React.js & Angular:

Though both react js and angular seems similar, but still there is significant contrast that differentiates both React.js and Angular, which is given below.

Field
React.js
Angular
Used as

React.js is a JavaScript library. As it indicates react js updates only the virtual DOM is present and the data flow is always in a single direction.

Angular is a framework. Angular updates the Real DOM and the data flow is ensured in the architecture in both directions.

Released It was released in 2013. It was released in 2010.
Architecture

React.js is more simplified as it follows MVC ie., Model View Control. This like angular includes features such as navigation but this can be achieved only with certain libraries like Redux and Flux. Needs more configuration and integration.

The architecture of angular on the other hand is a bit complex as it follows MVVM models ie., Model View-ViewModel. This includes lots of tools and other features required for navigation, routing, and various other functionalities.

Performance

React.js holds JSX hence the usage of HTML codes and syntax is enabled. But this doesn’t make react js a subset of HTML. This is purely JavaScript-based.

Angular, on the other, is a mere subset of HTML.

Preference

React.js is preferred when the dynamic content needed is intensive. As react js holds more straightforward programming and since it is reliable many apps such as Instagram, Facebook, and Twitter still prefer to react js over angular.

Angular is platform-independent and hence is compatible to work in any platform. Hence, the HTML app which is compatible with all the browsers can prefer angular. One major app which uses angular is YouTube.

Written

React.js written in JavaScript.

Written in Microsoft’s Typescript language, which is a superset of ECMAScript 6 (ES6).

Dependency Injection

React.js Does not use the Dependency Injection concept.

Angular Hierarchical Dependency Injection system used.

Routing Routing is not easy in React JS. Routing is comparatively easy as compare to React JS.
Scalability It is highly scalable. It is less scalable than React JS.
Data Binding It supports Uni-directional data binding that is one way data binding. It supports Bi-directional data binding that is two data binding.
DOM It has virtual DOM. It has regular DOM.
Testing It supports Unit Testing. It supports both Unit testing and Integration testing.

Note: Angular is a great framework it has many improvements in terms of ReactJS, it is good at bigger applications. If you are a beginner or have less coding practice also if you want stability for your project you can go with ReactJS.

Khi nào nên sử dụng React để phát triển ứng dụng?

Hãy cân nhắc lựa chọn React khi dự án của bạn đáp ứng:

  • Có chuyên môn cao về HTML, CSS và JavaScript
  • Nhóm của bạn cần một giải pháp ứng dụng thực tế với mức độ tùy biến
  • Tính chất thay đổi xảy ra thường xuyên: các mục điều hướng hoạt động/không hoạt động; vấn đề về quyền đăng nhập và quyền truy cập của người dùng, nút được bật/tắt,… đều có liên quan đến quá trình phát triển
  • Việc chia sẻ dự án diễn ra trên các ứng dụng (dự kiến)
  • Thật sự tập trung cho giai đoạn chuẩn bị (giai đoạn bắt tay thực hiện dự án)

Tổng quan về Angular 2 và React

  • Angular 2 là một web framework đầy đủ, trong khi React chỉ là một thư viện. Do vậy, để thực hiện so sánh 2 công cụ này, chúng ta tạm giả định React như một JS framework bởi vì dù sao React cũng luôn được sử dụng cùng với một vài thư viện JS để cung cấp một kiến trúc cho app dựa vào React. VD như các thư viện bao gồm Flux, MobX và Redux.

  • Angular 2 và React cùng là module hóa, cùng sử dụng kiến trúc module để phát triển các function như routing hay quản lý các dependencies trong một app SPA.

  • React cập nhật DOM nhanh hơn dựa vào DOM ảo. Và để khắc phục điểm yếu này, đánh bại được công nghệ DOM ảo của React, Google đã tiến hành thực hiện cơ chế phát hiện thay đổi trong Angular. Nhờ vậy, hiệu năng của cả Angular và ReactJS hiện giờ đủ tốt cho các app web hiện đại.

  • Cả React và Angular đều cùng sử dụng module đống gói là Webpack.

Để thuận tiện hơn, chúng ta có thể theo dõi bảng sau:

Javascript Framework Angular 2 React
Khái niệm Kiến trúc dựa theo component Kiến trúc dựa theo component
DOM thật DOM ảo
Render tại clien và server Render tại server
Cài đặt Tương đối dễ (Angular 1 khó hơn) Tương đối khó
Data binding Data binding 2 chiều Data binding 1 chiều
Quản lý dependency Sử dụng những công cụ được xây dựng sẵn cho quản lý sự phụ thuộc Yêu cầu ReactDI để quản lý sự phụ thuộc
Hỗ trợ ngôn ngữ TypeScript, CoffeeScript, Javascript JSX, JavaScript, TypeScript
Thoải mái khi sử dụng Ít thoải mái, phải tuân theo các quy ước Thoải mái hơn
Khả năng tiếp cận Khó khăn (yêu cầu dev có kiến thức nâng cao về JS) Dễ (chỉ cần dev có kiến thức trung bình về JS)

Trong bài viết này, ta sẽ đề cập đến các khía cạnh sau khi lựa chọn giữa Angular 2 và React cho một app SPA:

  • Cách thực hiện theo kiến trúc dựa vào component
  • Cách quản lý trạng thái của app
  • Chúng làm việc với những ngôn ngữ dựa theo JS gì?
  • Chúng cung cấp khả năng điều hướng gì?
  • Cách thực hiện quản lý sự phụ thuộc
  • Cách gắn dữ liệu giữa các template và các lớp Javascript
  • Cách tạo ra các template động

Angular vs React in 2023: which should you choose?

What is Angular?

Angular is a Google-developed and maintained web framework that was first released in 2010 under the name AngularJS. It quickly became one of the most popular web frameworks at the time. This was owing to capabilities like two-way data binding and dependency injection, as well as the fact that it was supported by a tech giant.

Angular (also known as Angular 2.0) was released in September 2016 as a complete redesign of AngularJS (Angular 1.0), which was first released in 2010.

What is React?

React is an open-source JavaScript library for front-end development to build UI components. Its component-based architecture and declarative views let developers create interactive and complex UIs easily. Developers can build fast and scalable apps for all platforms with its “learn once, write anywhere” principle. It is managed by Facebook’s React team and a vast development community.

Here are the distinctive features of React that set it apart from Angular:

  • Declarative views
  • JSX advantage
  • Virtual DOM
  • One-way data binding
  • Building blocks flexibility

Advantages of React

Let’s take a look at some benefits of React:

  • Reusable and more predictable code
  • Easier debugging with declarative views
  • Faster development time
  • Enhanced developer productivity
  • Easy migration between different versions
  • Support for mobile app development with React Native
  • Faster updates with both server-side and front-end support
  • Improved load time and performance with efficiently built UI
  • Integration with third-party libraries

AngularReact: When to choose which?

Angular: Angular speeds up front-end development and is known as the standalone solution for building the quickest data-driven web applications. Since Google’s Angular team is maintaining it, it is reliable and stable with massive community support. Below are some ideal use cases for Angular:

  • Design, maintain, and scale up large and complex applications (Angular’s use of components and directives makes it easier)
  • Build featureful elements and create customizations for the elements
  • Develop enterprise-scale and mid-level projects where you won’t require additional integrations of plugins and setting up third-party integrations. Adding external elements would add more complexities and a longer period, which is not recommended for complex requirements.

It is also ideal to choose Angular when you:

  • Need to develop feature-rich, enterprise-grade applications
  • Have application complexity from low to medium-level
  • House developers with good knowledge of C#, Java, and versions of Angular and want higher productivity
  • Want to build applications such as video streaming apps, e-commerce apps, real-time data apps, user-generated content-focused apps, and more. For instance, Forbes and Upwork are two popular names using Angular to manage heavy pages.

React: It is used for handling the view layer of the application, and developers prefer it to build reusable UI components. It is fast and scalable to change the data without reloading the page. React was first used on Facebook and later was implemented in the Instagram news feed. Most large-scale applications are using React to load the data without refreshing the pages. Other ideal React use cases include building social networking apps, data visualization tools or dashboards, retail and e-commerce apps, and more.

It is also ideal to choose React when you:

  • Want to build customized or personalized app solutions
  • Need an application with multiple events or sharable elements in your app
  • Have developers with good expertise in JavaScript, HTML, and CSS
  • Want to develop cross-platform mobile apps
Check how we improved the online web experience for International Hockey Federation (FIH) using React.

Angular and React have made significant applications for some major companies in the world. You can check out a few of the big brand names in the image below.

2) ReactJS

ReactJS is more of an open-source JavaScript library rather than a framework. With this, astonishing UI can be built with good rendering performance. React is more dependent on ‘view’ in the Model View Controller (MVC) architecture. It was launched to resolve the rendering issues of large datasets in JavaScript frameworks.

Reasons why ReactJS is recommended:

1) SEO Effective

ReactJS can be easily run on the server and then a virtual DOM will be rendered which will return to the browser as a web page. This a benefit because search engines find it hard to read JS-heavy apps which is the main issue with JS frameworks.

2) Excellent efficiency

ReactJS generates its own virtual DOM and also it takes care of all the changes to made in the DOM and any updates in the DOM tree. For gaining a good performance it is a great and flexible approach.

Here are the other pros and cons of React JS:

Advantages of React JS

  • It offers faster updates
  • Importing components is relatively very easy
  • With ReactJS you can reuse the code
  • JS debugging is smooth
  • It has easy learning API and smooth interface designs
  • Fully component based architecture

Drawbacks of React JS

  • The learning curve is steep
  • It is not a framework and just a library
  • Flux architectures
  • If you integrate React into an MVC framework, some configurations would be required

What is Angular?

Angular is a development platform and application-design framework built on TypeScript with component-based architecture for building scalable web apps. It has a collection of well-integrated libraries and features, such as client-server communication, routing, and more, that help speed up front-end development. It also has a suite of developer tools to develop and scale projects from single-developer size to enterprise-grade applications.

Angular is a complete rewrite of AngularJS (no longer maintained) from the same Google engineers’ team. However, Angular is constantly updated and is backed by a massive community of developers.

Here are the distinctive features of Angular that set it apart from React:

  • Two-way data binding
  • Dependency injection
  • Virtual scrolling
  • Angular CLI
  • Built-in libraries

Advantages of Angular

Let’s take a look at some benefits of Angular.

  • Strong encapsulation and an intuitive application structure
  • Clean code development
  • Ease in building, maintaining, testing, and updating
  • In-built features like Rxjs and AngularCLI
  • Built-in support for HTTP, AJAX, and Observables
  • Rapid rendering of server-side
  • Support for views that lack browser-side rendering
  • Fewer lines of code required due to parallelly running components
  • Improved developer productivity
  • Increased overall performance of the application

Certain Reasons why to choose Angular framework for Web Development

2.1 Created by Google

Angular is an open source framework that is developed as well as maintained by Google. It happens to be considered as one of the most famous frameworks in regards to security. As a result, many businesses have started preferring Angular framework for conducting web app development.

2.2 Simplified MVC Architecture

Angular ensures Model View Controller (MVC) for web application advancement. Actualizing MVC is quite simple here. The developer must be able to component the app and leave the rest to Angular technology.

In fact, with the use of Angular, there is no denying the fact that developers have gained more potential to create interactive, scalable, and feature-rich web applications. Apart from this, one shouldn’t forget about Angular’s MVC architecture, as a developer you have to add the app into components and the rest will be taken care of by the technology itself. Also with the help of MVC pipeline, you can reduce bigger code lines thus saving time and the need to write more code for the same functionality.

2.3 MVC (Model View Controller)

Angular supports MVC Architecture is one of the finest benefits of using Angular framework. Now for the successful implementation of the MVC architecture, Angular experts are expected to add apps into MVC components. That’s it! After this, let the Angular technology do its job. MVC stands for Model View Controller. To make the developer’s job easier Angular also offers an MVC pattern which helps them in managing the User Interface and the database easily. With the help of these angular features, you can accomplish more functionality with less code.

2.4 Active and Large Community

Developed by the tech giant itself, Angular’s tech community is growing by leaps and bounds. In case if the developer gets stuck or doesn’t know how to proceed further he can refer to the community and will soon find an adequate resolution.

In the community, you may come across a wide range of experts having skills and years of experience in the web development arena. They are capable enough to solve issues or frontend app development queries. There are also many Angular tutorials and courses available online for free where you can start learning.

2.5 Two-Way Data Binding

With two-way data binding, creating a template that can be easily synchronized with separate components and models becomes a seamless experience. Technically speaking if one value is changed in any HTML or view the mode value will automatically be changed. In the Angular framework, HTML can also be used as a template language.

On and all, this saves ample time as whatever changes are done can be seen right there on the app interface. With the help of dependency injection and data binding, you can get rid of much of the code which otherwise you had to write in other frameworks.

2.6 Real-Time Testing

By choosing Angular for your next project, there is no concept such as testing time. The real-time and in-built modules can enable developers to test every time. In Angular, you have two options first to go for an end to end testing or go for unit testing.

Now testing is quite essential for any and every web application and your chosen Angular developers will ensure that there is no error or bug found before launching the app.

2.7 Cross-Platform

With Angular, development of PWAs i.e. Progressive Web Apps are possible. Using Angular, developers can create apps that can run across various platforms like web, mobile (using NativeScript), and Desktop(using Electron).

2.8 High-end Performance

Did you know that Angular has this magic of creating clean semantic code from templates? The definition of modern javascript has been redefined.

Angular allows developers to write code (hand-written code) in such a way that it results in high-end speed and optimal server side rendering.

2.9 More on Why AngularJS?

As soon as it encounters aspects such as browser occasions or module modifications or any kind of user actions, what happens is that it automatically carries out the task of updating necessary patterns. Earlier, developers were asked to store links to DOM elements. Now it’s no longer necessary as they can be directly manipulated. Methods like low-level constructions are no longer in use. With angular, you are no longer required to wait for a longer testing time and you can also perform unit testing and integration tests. The tech features real-time and in-built modules. Both of them can be used for in-depth and functional testing. Due to all these features, developers prefer Angular in comparison to other frameworks.

2.10 What is Angular used for?

There is a reason why businesses prefer to use Angular. Angular is an open-source, structural dynamic web application framework, and tech giants like Microsoft and Samsung are found embracing this javascript framework. Other than these, some big-name companies included in the list are Deutsche Bank, Mixer, Gmail, Grasshopper, Delta, Overleaf, PayPal, and Upwork.

Companies use the Angular technology of their MEAN Stack comprising of these aspects –

  • MongoDB Database
  • Angular for front-side application development
  • Express.js web app server
  • Node.js server runtime environment

What Is Angular?

Angular is a TypeScript-based open-source platform and web application framework developed by a team from Google. The framework helps to create single-page applications using TypeScript and HTML. Angular is the technology you want if you’re looking to build applications for both mobile and web.

Unlike other frameworks, Angular offers two-way data-binding. This means that if you change a value in the input box, it will automatically update the added property value of the component class. In other words, it will create a real-time, flawless synchronization of data between model and view.

You may already be aware of this fact, but it bears repeating for new developers in the field who may mistake Angular and AngularJS for the same thing: They aren’t.

The core difference between Angular and AngularJS is that the former uses TypeScript (a superscript for JavaScript) as its core, while the latter uses JavaScript. In practice, Angular is more like an updated version of AngularJS.

3) NodeJS

NodeJS is a server rather than a framework which is powered by Google Chrome V8 JavaScript engine. It executes JavaScript on the server side. Its main application is done for simplifying development of complex applications.

Reasons why NodeJS is recommended:

1) Server-side proxy

NodeJS can handle numerous simultaneous connections in a non-blocking manner as it can be used as a server-side proxy. Mainly it is used when you want to proxy different services with varying response times.

2) NPM

NPM(Node Package Manager) comes by default with your Node.js installation and gives support for package management. NPM’s concept is similar to Ruby Gems. The most popularly used NPM modules are:

  • Mongojs and MongoDB
  • connect
  • moment
  • bluebird
  • pug
  • socket.io and sockjs

Here are the other pros and cons of NodeJS:

Advantages of NodeJS

  • The same piece of code is shared with both client and server side
  • Big files can be easily streamed
  • NPM has already become deep and rising at a fast rate
  • Simple to learn
  • Large support community

Drawbacks of Node JS

  • Not scalable because one CPU is not sufficient to take advantage of multiple tasks
  • Deep understanding of JavaScript is required to work with NodeJS
  • Relational database issues
  • Particularly suited for web servers and not meant for CPU-intensive tasks
  • Nested callbacks

Dependency Injection trong Angular 2 và React

Dependency injection (DI) là một khái niệm để phân biệt Angular 2 và React; DI là một phần trong Angular framework, trong khi trong React thì không định nghĩa khái niệm DI.

Trong một app Angular, dependency injection cho phép chúng ta loại bỏ sự trùng lặp của các lớp giống nhau với các dữ liệu giống nhau trong các component khác nhau. Nếu bạn có 2 component: một component là cha, và component khác là con. Chúng luôn chia sẽ dữ liệu, như một model và một mảng đối tượng. Nếu như không có dependency injection, bạn sẽ phải copy và paste model và mảng từ component cha sang các component con của nó. Nhưng Angular 2 giúp bạn tránh điều đó bằng cách sử dụng module

@Injectable

và một vài lớp dịch vụ đặc biệt:


import { Injectable } from '@angular/core'; import { Team } from '../models/team'; const teams: Team[] = [ { id: 524497, name: 'Renault Sport F1', username: 'RenaultSportF1', image: 'https://pbs.twimg.com/profile_images/833997138417819651/LMzylD_R_400x400.jpg' }, { id: 123153, name: 'McLaren F1', username: '@McLarenF1', image: 'https://pbs.twimg.com/profile_images/831538604409233408/w4jg5JtR_400x400.jpg' }, { id: 125448, name: 'Scuderia Ferrari', username: '@ScuderiaFerrari', image: 'https://pbs.twimg.com/profile_images/712562570897580032/amoHCwrI_400x400.jpg' } ]; @Injectable() export class TeamService { //the function that returns all teams getTeams() { return teams; } }

Service này phải được đăng ký trong NgModule trong mảng provider. Bạn có thể loại bỏ code lặp từ các component cha và con bằng cách sử dụng service inject

Angular tự động tạo ra một dependency injector để bạn có thể cho vào tất cả các đối tượng service chứa cùng thông tin giống nhau được dùng trong các component

Vậy bạn có thể chia sẽ các dữ liệu cho các component React như thế nào? React yêu cầu một thư viện đặc biệt, gọi là

ReactDI

để quản lý sự phụ thuộc. Với thư viện này, nó có thể đăng ký tất các lớp dịch vụ và gửi chúng vào một vài component. Với các component, bạn có thể gọi một dịch vụ cần thiết sử dụng hàm di() và truyền hàm vào service.

Nếu bạn muốn sử dụng Angular, bnaj phải thỏa thuận với dependency injection. Với React, bạn có thể tránh hoàn toàn dependency injection. Tuy nhiên, bạn có thể muốn sử dụng dependency injection trong React. Các thư viện JavaScript như ReactDI và Inversify JS làm cho React có thể sử dụng dependency injection.

Lựa chọn giữa JSX và TypeScript của React và Angular 2

Tác giả của Angular 2 và React đã quyết định cung cấp một framework không đầy đủ. Để đáp ứng với nhưng yêu cầu phức tạp, các dev Angular và React phải học thêm một vài công nghệ bổ sung – TypeScript hay JSX. TypeScript là một tập hợp JavaScript và được khuyến khích cho phát triển Angular 2 app. JSX là một ngôn ngữ đặc biệt, được phát minh bởi Facebook và thay thể Javascript trong app React. TypeScript và JSX rất khác nhau trong syntax và cách làm việc.

Ngôn ngữ TypeScript phù hợp với Angular 2, nó khá giống JavaScript. Sức mạnh thực sự của TypeScript được thể hiện khi bạn muốn xác nhận chính xác kiểu dữ liệu trước khi thực thi. VD, trong một component Angular:


export class Laptop { id: number; title: string; price: number; cost: number; description: string; stock: number; }

Mỗi thuộc tính của model laptop được gán với kiểu cụ thể. Trình biên dịch sẽ so sánh mỗi đối tượng laptop với model trên và thông báo nếu một component được gán sai kiểu giá trị. VD, một mảng các laptop trong LaptopsComponent:


import { Laptop } from './laptop'; //import the Laptop model export class LaptopsComponent { laptops: Laptop[] = [{ "id": 1, "title": "Samsony", "description": "The Best Laptop Ever", "price": 14999, "cost": 10000, "stock": "100500" // Alert! This won’t compile! 'stock' must be a number }, { }, { }];

Cú pháp

Laptop[]

trong ví dụ trên nói với TypeScript là xem xét biến laptop như một mảng các đối tượng của Laptop. Và nếu chứa các giá trị khác ngoài number, TypeScript sẽ cảnh báo chúng ta.

Điều quan trọng cần chú ý là bạn không cần phải bắt buộc sử dụng TypeScript; Angular 2 làm việc tốt với vanilla JavaScript. Và nếu là một Ruby on Rails dev, bạn sẽ thấy vui khi biết là nó có thể sử dụng CoffeScript với Angular 2.

JSX khác xa so với TypeScript về syntax.


class NewComponent extends React.Component { render() { return(

This is My { this.state.component }

This component is a React component.

) }; };

Đằng sau đó, code trong hàm return được dịch thành:


React.createElement("div", { className: 'wrapper' }, React.createElement("h1", { className: 'title' }, `This is My ${ this.state.component }`) )

Hàm createElement sẽ tạo ra một đối tượng JavaScript với các thuộc tính như

div



class

với các giá trị tương ứng.

JSX cũng cho phép bạn gắn JavaScript trực tiếp vào trong template: chỉ cẩn đóng gói code JS vào trong ‘{}’ và JSX sẽ tính toán giá trị tự động.

Mặc dù JSX khá giống HTML, nhưng thực sự nó không hoạt động như HTML. Code trong hàm render sẽ luôn được biên dịch thành một đối tượng JS với một tập các thuộc tính.

Facebook khuyến khích nên sử dụng JSX, nhưng bạn cũng không cần phải bắt buộc dùng nó. Bạn có thể sử dụng vanilla JS nếu thích. VD, tọa một template, bạn có thể gọi hàm createElement với tập các tham số – tên của HTML element, nội dung HTM, .. thay vì viết bằng JSX. Mặc dù vậy, trong thế giới React, bạn luôn có một lời khuyên là sử dụng JSX.

JSX rất dễ đọc, dễ dùng và viết JSX đơn giản hơn viết hàm JS trực tiếp.

1) AngularJS

Angular JS is a client-side web framework launched in 2009 by Google. It was aimed to resolve issues in creating single page application faced by angular developers. With a large support community, it has an extensibility feature and can work well with several libraries.

Reasons why AngularJS is recommended:

1) User interface

AngularJS has the plus point of using HTML for defining web app’s user interface. HTML is less fragile to recognize and also it is a declarative language. Overall it offers simplification of web development process in which you just need to define what you want.

2) Flexibility

Web app development is made flexible with the use of directives and filters. The benefit of using directives is that they bring functionality to HTML rather than manipulating the DOM. Filters, on the other hand, are standalone functions that are separate from the app. Still, they take care of data transformations.

3) Testing

Unit testing in AngularJS is done by injecting mock data and then measuring the output. This is a completely different way of testing web apps in which individual test pages are created.

Let’s go over the technical aspects for choosing AngularJS over others:

Advantages of AngularJS

  • Easily testable framework
  • Data synchronization is done automatically between the components and model view
  • Vast Angular libraries
  • Inbuilt dependency injection subsystem
  • Simple routing
  • Angular Data binding
  • Marvelous UI design
  • Customized Document Object Model can be created easily
  • It provides strong template building solutions

Drawbacks of choosing Angular JS

  • DOM elements come with performance issues
  • Limited Routing offered
  • Scopes are difficult to debug
  • Angular gets slow with pages embedding interactive elements
  • Third party integration is very complex
  • The learning curve is steep

For more detailed information on Angular JS, here is a guide on Angular JS to help you understand the javascript framework better.

AngularReact: When to choose which?

Angular: Angular speeds up front-end development and is known as the standalone solution for building the quickest data-driven web applications. Since Google’s Angular team is maintaining it, it is reliable and stable with massive community support. Below are some ideal use cases for Angular:

  • Design, maintain, and scale up large and complex applications (Angular’s use of components and directives makes it easier)
  • Build featureful elements and create customizations for the elements
  • Develop enterprise-scale and mid-level projects where you won’t require additional integrations of plugins and setting up third-party integrations. Adding external elements would add more complexities and a longer period, which is not recommended for complex requirements.

It is also ideal to choose Angular when you:

  • Need to develop feature-rich, enterprise-grade applications
  • Have application complexity from low to medium-level
  • House developers with good knowledge of C#, Java, and versions of Angular and want higher productivity
  • Want to build applications such as video streaming apps, e-commerce apps, real-time data apps, user-generated content-focused apps, and more. For instance, Forbes and Upwork are two popular names using Angular to manage heavy pages.

React: It is used for handling the view layer of the application, and developers prefer it to build reusable UI components. It is fast and scalable to change the data without reloading the page. React was first used on Facebook and later was implemented in the Instagram news feed. Most large-scale applications are using React to load the data without refreshing the pages. Other ideal React use cases include building social networking apps, data visualization tools or dashboards, retail and e-commerce apps, and more.

It is also ideal to choose React when you:

  • Want to build customized or personalized app solutions
  • Need an application with multiple events or sharable elements in your app
  • Have developers with good expertise in JavaScript, HTML, and CSS
  • Want to develop cross-platform mobile apps

Simple React js example

Angular: It is a popular open-source JavaScript framework created by Google for developing web applications. Front-end developers use frameworks like Angular or React for presenting and manipulating data efficiently. Updated Angular is much more efficient compared to the older version of Angular, especially, the core functionality was moved to different modules. That’s why it becomes so much fast and smooth compare to the older one. Newly added angular CLI. With that package, you can create a scaffolding for your Angular project.

Features of Angular:

  • Accessibility: It provides easier access as it holds ARIA-enabled components.
  • Templates: Angular holds several templates to create UI views in a much faster manner by providing and suggesting some syntax.
  • Testing: The program here is broken into several chunks which makes it easier to test. Testing is performed by the protractor in this case.

Example: This example demonstrates the simple Angular program.

Angular vs React: Which to Choose for Your Front End in 2024?

Some say comparing Angular and React is like comparing apples to oranges. Angular is a JavaScript framework built using TypeScript, while React is a JavaScript library built using JSX. Add a few libraries to React, and you can turn it into a complete framework. But the resulting stack workflow is still very different from Angular, so the comparability is limited.

On the other hand, both React and Angular have component-based architecture, resulting in both having reusable and modular elements aiming to solve similar front-end problems. And thus, there is a never-ending debate on Angular vs React in the development community.

So, which one is better? This article gives an in-depth comparison of Angular and React based on various factors to help you analyze which is best suited for your project.

So, which is better?

All in all, both can be the right frameworks are great for building modern mobile and web applications with component-based architectures. Choose the one that best suits your project functionalities, preferred programming paradigm, project workflows, and the skills of your developers.

React is somewhat choosing an easy way to get the job done since it hasn’t much to do with organizing HTML but instead has the simplest ways to reuse the UI components. While Angular is capable of handling multiple things on its own without depending on any additional help, it may seem tricky at first. However, the benefits foresee the more extended concept and outweigh the time invested.

React is a go-to option for one pizza team since they would want to build an application out of a small learning curve. While building an enterprise-grade application with big development, teams can choose Angular since the bigger learning curve is no bar for them.

Whether it is Angular or React, we are here to help you build highly performant web apps

React is a JavaScript library, whereas Angular is a TypeScript-based JavaScript framework. React uses one-way data binding and virtual DOM trees, whereas Angular uses two-way data binding and real DOM. Moreover, React is faster than Angular as it has a smaller bundle size.

Angular is a full-fledged structural framework based on TypeScript for building mobile and desktop web apps, while React is an open-source library based on JavaScript for creating interactive and complex user interfaces. Angular is mostly used to build complex enterprise-grade apps like single-page apps and progressive web apps.

Angular is better than React if your application is enterprise-grade and you need to incorporate complex functionalities like progressive, single-page, and native web apps. Since it is a full-fledged framework, functions such as data binding, dependency injection, component-based routing, form validation, and project generation can be implemented with Angular packages. In React, this requires additional libraries or modules to be installed.

Moreover, Angular has pre-built material design components. To use them in React requires installing additional library– Material-UI Library & Dependencies. However, React specializes in creating UI components and can be used in any application, including single-page apps.

In terms of performance, bundle size, and backward compatibility, React outperforms Angular. The component-driven architecture of React allows developers to reuse code components, which tends to save cost and time. It also outperforms Angular due to its rendering optimizations and Virtual DOM implementation. Also, React developers can access many pre-built solutions for development.

In comparison to Angular, React is faster and easier to learn. Angular has a steeper learning curve due to several in-built functionalities, so it takes more time initially. React has a shorter learning curve due to its simple structure, use of plain JavaScript, and small package size.

Angular uses TypeScript, a superset of JavaScript. It is an object-oriented, high-level web programming language developed and maintained by Microsoft. JavaScript is a popular scripting language used to create interactive web applications.

Angular is a Google-developed open-source JavaScript framework. Angular is capable of creating all of the dynamic features that are often seen on a website. Its primary goal is to aid in the development of a single-page application because Angular places a premium on code readability and configurability, web developers prefer the angular framework over any other JavaScript Framework. Amazon, Netflix, and Gmail are just a few of the major websites and services that leverage and love Angular.

The following post emphasizes what Angular is and why this frontend framework is highly recommended for developing web applications . However, this is not it, for optimal implementation of Angular project/s, one must also look around for Angular best practices and robust security.

Conclusion

With so many frameworks to pick from, each with its unique set of characteristics, settling on the best framework can be a difficult task.

We felt the same way when we first opted to build the app in Vue.js and now while we’re exploring Angular.

When it comes to choosing between Angular and React, I believe it comes down to personal preference, as they both tackle the same problems but in different ways.

However, when making a selection, keep in mind that React has a simpler learning curve, which leads to faster development, but Angular offers more built-in functionality.

Both technologies are extremely powerful, a significant advancement from the early days of web programming in terms of improving, facilitating, and speeding up development.

So sánh Angular và React

Mức độ phổ biến

Theo Google Trending, React nhận được quan tâm nhiều hơn so với Angular. Tuy có sự phân chia rõ về lượt tìm kiếm; song cả hai đều phổ biến và có sức ảnh hưởng riêng trên thị trường.

Kiến trúc

Cả 2 đều có kiến trúc component-based. Nghĩa là có cùng các thành phần gắn kết, tái sử dụng và mô đun. Nhưng, trong sự giống nhau tổn tại sự khác biệt. Và điều đó nằm ở khía cạnh công nghệ.

React sử dụng JavaScript trong khi Angular đi kèm với Typescript với việc phát triển web nhỏ gọn hơn.

Lộ trình học tập

Cả hai đều đòi hỏi ứng viên nắm bắt và trau dồi các kiến thức cơ bản nhất; trước khi quyết định đi đến giai đoạn học tập nâng cao. Làm quen với các khái niệm và ngôn ngữ khác nhau như templates, pipes, dependency injection, RxJS, TypeScript… là một trong những yêu cầu cần thiết.

Hệ sinh thái Angular rất đa dạng, tạo môi trường tốt để nâng cấp các kỹ năng. Và đôi khi, nó rất thách thức. Ngược lại, Reactjs cho phép bạn dễ dàng tìm hiểu và tạo một ứng dụng trong hệ sinh thái nếu bạn thật sự giỏi về JavaScript.

Tốc độ phát triển và năng suất

Angular toàn diện hơn khi cung cấp trải nghiệm phát triển nâng cao – nhờ vào CLI. Vậy nên, quy trình tích hợp được xử lý hiệu quả; theo dõi và cập nhật các giải pháp tối ưu với các tính năng code rõ ràng.

Mặt khác, React với tốc độ phát triển và năng suất bị ảnh hưởng do sự tham gia của các thư viện bên thứ ba. Chính vì điều này mà việc xác định cấu trúc ban đầu trở thành một vấn đề khá quan trọng đối với các lập trình viên.

Mức độ phổ biến

Một yếu tố khác góp phần vào sự lựa chọn React và Angular là tính linh hoạt. React framework mang lại sự tự do lựa chọn các công cụ; thư viện và kiến trúc để phát triển một ứng dụng.

Khác với Reactjs, Angular tính linh hoạt bị giới hạn. Và nhiều chứng minh thực tế cũng cho thấy React mang đến sự linh hoạt và tự do tốt hơn so với Angular.

DOM (Document Object Model)

Một thực tế dễ đoán khi React sử dụng Virtual DOM chiến thắng Angular khi sử dụng real DOM. Cả hai đều có những ưu điểm riêng. Thế nhưng, Virtual DOm nổi bật hơn hẳn nhờ việc theo dõi và cập nhật các thay đổi mà không ảnh hưởng đến các phần khác.

Ràng buộc dữ liệu

Data Binding được cho là yếu tố ảnh hưởng đến việc xác định khung phù hợp.

React sử dụng liên kết dữ liệu một chiều. Trong khi đó, Angular gắn liền với phương pháp ràng buộc hai chiều. Cho dù cách tiếp cận của Angular được xem là dễ dàng và hiệu quả hơn. Nhưng xét trên khía cạnh tổng thể về mức độ ổn định của dữ liệu, React thật sự vượt xa mong đợi khi cung cấp một tổng quan dữ liệu tốt hơn so với Angular.

Hiệu suất ứng dụng và trải nghiệm người dùng

React dùng Virtual DOM và Fiber để kiểm soát các ứng dụng dẫn đến AngularJS. Còn Angular thì đưa ra các tính năng và yếu tố như ShadowAPI.

Giải pháp di động

>>> Xem thêm: tuyển dụng angular

React nổi trội hơn hẳn khi tạo ra trải nghiệm UI thực sự riêng biệt; nó khác hoàn toàn với Angular. Dù Angular đi kèm với bộ chứa Cordova và thư viện thành phần UI hấp dẫn. Tuy vậy, so về tính linh hoạt thì React có phần nhỉnh hơn đôi chút.

Kiểm tra – Nên học angular hay react?

Đối với Angular, việc kiểm tra và sửa lỗi không quá khó khăn khi có công cụ phù hợp và đòi hỏi tính kỹ thuật cao. Nhưng, Reactjs thì ngược lại, nó không thể thực hiện được trong trường hợp phát triển ứng dụng React js.

Tính dễ cập nhật

Angular có CLI giúp dễ dàng nâng cấp ứng dụng lên các phiên bản mới hơn một cách nhanh nhất.

React cũng tương tự về việc có các bản cập nhật mới. Tuy vậy, vấn đề bên thứ 3 tạo ra nhiều bất cập. Các developer phải kiểm tra mọi lúc về tính tương thích của khung JavaScript sao cho phù hợp nhất. Điều này là cản trở khá lớn và khiến React chậm nhịp hơn Angular.

Tài liệu

Tài liệu trong khung Angular so với Reactjs chậm hơn do quá trình phát triển đang diễn ra. Tuy nói như vậy nhưng khung React cũng đang được cập nhật thường xuyên.

Hỗ trợ cộng đồng

Cộng đồng GitHub cho thấy sự phát triển và lan tỏa khả mạnh mẽ. Và minh chứng rõ ràng nhất là cuộc đua giữa React và Angular. Với những khảo sát thực tế từ cộng đồng, thì React có tính hỗ trợ cộng đồng cao hơn Angular.

What Is React?

React is an open-source JavaScript library developed by a team from Facebook. React is commonly used to create user interfaces for single-page applications from isolated components.

It can handle web and mobile apps’ view layers. Thus, React supports web and mobile app development. This flexible framework also makes it possible to create complex apps if you utilize it alongside other supporting libraries.

React has one-way data binding, meaning its structure flows from parent to child. However, for two-way data binding, React offers LinkedStateMixin, which sets up the general data flow loop pattern.

In the traditional data flow, for every new data input, one had to reload the whole page to view the changes. In React, a reload isn’t necessary. That’s because React doesn’t create any extra Document Object Models (DOM) as a traditional data flow would when accepting new updates to data.

What is Angular?

In addition to the overview, Angular was constructed in 2009 by Google engineers with the intention of easing front-end development. It has grown in popularity across engineers and creators alike due to the fact that it includes everything necessary to build out the front end of websites.

Angular overcomes several of HTML’s constraints and spares developers from needing to either fool the reader into performing what they want or enjoying hours writing a bunch of additional code.

Presently, Angular is the most widely used framework in the web development industry for developing Single Page Applications (SPA’s), such as PayPal. The Angular framework streamlines the whole web development cycle, and it is supported by a vibrant community of engineers and users.
