How to create your first mobile app using Ionic Angular

Who uses Angular?

The best way to show that technology is effective and efficient is if market leaders use it for their projects. For Angular, this is true, as some of the biggest companies in the world rely on it.

Google created Angular and was the first to utilize it for various projects: Google Ads, Google Store, Google Cloud Source Repositories, G Suite, and Gmail.

Angular can be used for interactive support for Microsoft Office users and other applications like FindTime, Microsoft Events, or Microsoft Flow.

Apple generally favors developing its technologies and systems; however, it borrowed Angular from other developers to create an after-sales support service.

The Angular framework handles Adobe product user support.

Cisco Systems, a technology giant, needed a search engine that could keep up with its large and ever-growing data. So it built its own using Angular.

Angular was used to develop the main portions of McDonald’s’ website and mobile versions.

WIX is one of the largest CMS platforms, and Angular was instrumental in helping her build support for her users.

Step 2: Create a New Ionic Angular Project

Once the Ionic CLI is installed, you can use it to create a new Ionic-enabled Angular project. To do this, run the following command in your terminal:


ionic start myAppName tabs --type=angular

This command will create a new Angular project with Ionic, the name “myAppName”, and the tabs starter template.

Introduction

Let’s start my describing each of the tools we’ll be working with.

If you’re reading this article, you probably already know that Angular is a framework for building complex, single-page web applications (SPAs) and dynamic user interfaces. It uses a component-based architecture, in which individual pieces of functionality are broken down into reusable components that combine into larger applications.

Ionic is a popular open-source mobile app development framework that provides a set of pre-built UI components and tools for developing hybrid mobile applications that can be deployed to multiple platforms, including iOS, Android, and the web. One of the most common ways to use Ionic is in conjunction with Angular.

Capacitor is an open-source cross-platform native runtime that provides a set of APIs for accessing native device functionality, such as camera, geolocation, and sensors. Capacitor was created by the Ionic team, and it is designed to work seamlessly with the Ionic Framework, as well as other popular frameworks like React, Vue, and Angular.

Finally, Electron provides a runtime environment that allows developers to wrap web applications and run them as desktop applications on Windows, macOS, and Linux.

Now let’s combine these tools so we can create iOS, Android, and desktop apps using Angular.

Angular mobile app development models: cross-platform and hybrid

Angular is primarily considered a web technology, but in fact, it’s a cross-platform powerhouse, perfectly fit for developing mobile applications. Obviously, decisions about tech stack are not easy. A lot depends on the project’s requirements and the skills of your developers.

Let’s make things clear from the start: you can’t use Angular to create native mobile apps for iOS and Android. If the native approach is your priority, you need to go for native technologies, i.e., Swift/Objective-C for iOS and Java/Kotlin for Android. Still, Angular can help you deliver high-performance mobile apps with great UIs if you couple it with complementary technologies.

Google’s framework is an excellent choice if you’re fine with a non-native approach and want to develop hybrid apps or cross-platform apps. For the latter option, Angular is often used in combination with NativeScript, which acts as a bridge between Angular codebase and the native APIs of iOS and Android.

Instead of using a webview like hybrid applications, NativeScript translates Angular components and code into native UI components and functionality. This means that your app runs directly on the device, providing a native-like user experience.

Ionic, on the other hand, takes a hybrid approach by using web technologies (HTML, CSS, JavaScript programming language) to create mobile apps that run inside a webview. While it provides a consistent and responsive UI, Ionic apps are not truly native since they rely on web technology wrapped in a native container.

Still, Ionic apps offer a consistent user interface and are known for their quick development cycle and broad code reuse.

Install Ionic Tooling

Run the following in the command line terminal to install the Ionic CLI (

ionic

),

native-run

, used to run native binaries on devices and simulators/emulators, and

cordova-res

, used to generate native app icons and splash screens:

To open a terminal in Visual Studio Code, go to Terminal -> New Terminal.


npm install -g @ionic/cli native-run cordova-res

The

-g

option means install globally. When packages are installed globally,

EACCES

permission errors can occur.

Consider setting up npm to operate globally without elevated permissions. See Resolving Permission Errors for more information.

Create an App

Next, create an Ionic Angular app that uses the “Tabs” starter template and adds Capacitor for native functionality:


ionic start photo-gallery tabs --type=angular --capacitor

When prompted to choose between

NgModules

and

Standalone

, opt for

NgModules

as this tutorial follows the

NgModules

approach.

This starter project comes complete with three pre-built pages and best practices for Ionic development. With common building blocks already in place, we can add more features easily!

Next, change into the app folder:


cd photo-gallery

Next we’ll need to install the necessary Capacitor plugins to make the app’s native functionality work:


npm install @capacitor/camera @capacitor/preferences @capacitor/filesystem

PWA Elements

Some Capacitor plugins, including the Camera API, provide the web-based functionality and UI via the Ionic PWA Elements library.

It’s a separate dependency, so install it next:


npm install @ionic/pwa-elements

Next, import

@ionic/pwa-elements

by editing

src/main.ts

.


import { defineCustomElements } from '@ionic/pwa-elements/loader';

// Call the element loader before the bootstrapModule/bootstrapApplication calldefineCustomElements(window);

That’s it! Now for the fun part – let’s see the app in action.

Code sharing

One of the best features of Native Script is code sharing. As we mentioned above, there are no differences from Angular 2. If native functionality is required, it is simply injected as a provider or a service into the app.

Here is a real app (based on cross-platform Seed), where not a line was changed, except for layout templates.

iOS Simulator, Android Emulator, and Chrome. This is a demo app, which contains all the key points of a real app, several pages, localization, routing, and a simplest data structure. Besides that, this app is assembled as a desktop one, using ElectronJS for macOS and Windows as a basis. The source data can be downloaded here: github.com/NathanWalker/angular-seed-advanced

We should mention the opportunity of making a native app with Ionic 2 and NativeScript: hybridtonative.com/#developing-a-ui-with-ionic-2. This is a massive document that describes the step-by-step process of making a native app out of an existing PhoneGap/Ionic application.

One more advantage is an option of using ES6 by default. As we mentioned, NativeScript utilizes the V8 virtual machine in Android and JavaScript Core in iOS. All the ES6, which is available in the abovementioned machines, can be used directly in NativeScript.

  • Extension of existing native apps
  • Native modules in С++ are similar to Node.js add-ons
  • Node.JS API by the end of the year
  • Work with Android widgets
  • Tests with Mocha.js, Appium, etc.
  • Universal Windows Platform
  • Telerik App Builder
  • WebInspector & NodeInspector for debugging
  • Default Themes
  • v.2.4

The evolution of Angular: from AngularJS to Angular

Angular is frequently mixed up with AngularJS due to the name similarity. In reality, both frameworks are fundamentally different in architecture and capabilities. Plus, AngularJS was discontinued in January 2022 and is no longer supported. Nevertheless, both technologies have more in common than the name.

AngularJS, also known simply as Angular 1, made its debut in 2010 under the stewardship of Google. It was a groundbreaking JavaScript framework designed to simplify web app development. AngularJS pioneered two-way data binding, enabling sharing data between a component class and its template.

It also prioritized declarative programming – over the imperative approach recommended for business logic – in building user interfaces and joining software components. Overall, it helped enhance user experience while heavily reducing the amount of boilerplate code developers had to write, saving time and costs.

The framework quickly gained popularity and became a cornerstone for building dynamic web applications. However, in the tech industry, things change fast. Soon, AngularJS started to show limitations related to building large-scale applications. Performance was also far from stellar.

A few years into its evolution, the framework struggled to keep pace with modern web requirements. As hurdles piled up, Google’s Angular team had no other option but to rethink their approach. In 2016, the company released Angular 2.

The new iteration was not an incremental update but a complete rewrite of the framework. It successfully addressed the shortcomings of AngularJS and provided developers with a more robust and flexible toolset for building exceptional user interfaces.

One of the key differences between Angular and AngularJS is the language used. While AngularJS relied on JavaScript, Angular adopted TypeScript, a statically typed superset of JavaScript. TypeScript brought strong typing, enhanced tooling, and improved code maintainability to the table, making Angular applications more robust.

Another vital update is the change from two-way data binding to one-way data flow. Angular introduced a unidirectional data flow model, making it easier to manage the state of applications and reducing unexpected side effects. This change helped developers build more predictable and maintainable code.

Angular 2 and its later versions (an interesting tidbit is that the number 3 was left out due to a router’s package versioning misalignment) were structured as a collection of reusable components, emphasizing code reusability.

Since its “refurbishment,” the framework has been heavily focused on performance optimization, aided by features like Ahead-of-Time (AOT) compilation or change detection mechanisms. These and other refinements helped to deal with the predecessor’s major drawbacks, making Angular web and mobile applications faster and more efficient.

Conclusion

With the help of Capacitor, Ionic, and Electron, we can easily integrate our Angular apps with iOS, Android, and desktop OSes, and debug them using standard debugging tools. This allows for a streamlined development process and faster time to market for your mobile and desktop apps.

Angular is a popular framework backed by a huge community, favored by many developers, and used by leading corporations, including Google, Microsoft, and Samsung. Find out how it can streamline mobile app development.

In software development, efficiency is paramount. Building maintainable and scalable applications requires a lot of proficiency and experience, which enable you to leverage the right development tools to optimize the cost-benefit ratio without compromising quality.

That’s exactly the role of frameworks. They are convenient toolboxes comprising reusable libraries, preset tools, SDKs, ready-to-use components, etc. Frameworks provide engineers with a structured, time-tested approach to streamline the software development process, ultimately contributing to superior user experience and cost reduction.

So which one fits your project better – ReactNative or NativeScript?

ReactNative developers will help you create a rather simple app and launch it quickly on the market. As the software product owner, you might leave out a couple of ideas regarding design or functionality in case there is no corresponding plugin for a needed component or feature. ReactNative works best if your software product stands out not with its design, but rather with the business logic.

NativeScript – requires more effort to ensure responsiveness for the end-user—the same responsiveness that is achieved in ReactNative with Web Workers in case of complex calculations. In return, you get absolute control over any native functionality and high level of customization of any control directly from JS code. Your developer does not need to know Objective-C or Java to write a new plugin or a wrapper for a 3rd-party native library. What’s more, it’s possible to extend classes of native components using JS.

These two tools address different cases and have different pros and cons.

Key features and advantages of Angular for mobile development

With its ability to target multiple platforms simultaneously, Angular is one of the best toolsets for secure mobile app development. Well-crafted Angular-based software doesn’t fall far behind native apps in terms of performance or user experience while offering cost efficiency and a much shorter time to market.

Let’s look at the key features and strengths of Google’s open-source framework.

Code reusability

Angular’s component-based architecture promotes reusing code. Developers can create reusable UI components, services, and logic, minimizing redundant code, speeding up development, and streamlining maintenance and updates. Again: lower costs, faster results.

Convenient CLI

Angular CLI simplifies project setup, scaffolding, and maintenance, ensuring a smooth development process. It comes with various optimization techniques, such as ahead-of-time (AOT) compilation, that minimize bundle size and enhance app performance.

TypeScript

Angular’s use of TypeScript enhances code quality and maintainability by identifying errors at compile time instead of runtime. Such an approach effectively reduces the likelihood of bugs making it to the production phase.

TypeScript also ensures consistency in data structures and interfaces across the app, contributing to maximized performance.

Native app-like experience

With technologies like NativeScript and Ionic, Angular mobile apps can be transpiled into native code, leveraging the capabilities of a mobile device for a seamless user experience.

Both Angular frameworks provide the means to create efficient and visually appealing near-native apps, all while benefiting from the productivity and code reusability of the Angular ecosystem.

State management

Angular provides robust solutions for state management, i.e., handling application inputs across multiple related data flows. They include built-in support for reactive programming through RxJS and NgRx for more complex state management scenarios.

State management tools facilitate controlling the application’s state and managing numerous interactions, contributing to the responsiveness, maintainability, and scalability of Angular mobile apps.

Progressive Web App (PWA) support

Angular offers strong support for progressive web application development with features like service workers and the @angular/pwa package, simplifying PWA implementation.

Angular service workers (JavaScript middleware acting as a proxy server between an app, a browser, and the network) provide offline support, background synchronization, and efficient caching of assets and data.

Additionally, Angular’s responsive design capabilities make it easier to create PWAs that adapt seamlessly to a user’s mobile screen size.

A couple of words about performance

Only old versions were tested. However, it’s enough for general understanding and evaluation.

Last update: March 2016

Requirements: iOS 8 + device (iPhone 5S)

  • Native – Xcode 6.3.2
  • NativeScript – NativeScript for iOS 1.6.0
  • Xamarin – Xamarin Studio 5.10.2
  • Appcelerator – Appcelerator CLI 4.1.0
  • Cordova – Apache Cordova 5.1.1
  • React Native – 0.19

We will start with the simplest: startup time of a simplest app with a single button:

Platform Run 1 Run 2 Run 3
Native 111ms 105ms 108ms
React Native 358ms 361ms 353ms
Xamarin Forms 484ms 471ms 469ms
Cordova 613ms 612ms 609ms
NativeScript 674ms 672ms 670ms

As you can see, NativeScript ranks last. When an app loads, a reflection of JS code call to corresponding native objects is being built. It takes time. The official website offers tips to speed up the startup time, e.g. code minification and packaging in a single bundle. However, this refers only once to startup time. This mechanism is not required after the launch.

Now we’d like to discuss work with primitive data types. The following tables illustrate data transmissions between the native and JS parts:

Here is transmission of average data packages (1 kilobyte) between the JS and native parts.

Platform Run 1 Run 2 Run 3
Native 5ms 4ms 4ms
Xamarin 27ms 27ms 28ms
NativeScript 989ms 998ms 980ms
Cordova 613ms 612ms 609ms
Appcelerator 34444ms 33969ms 35916ms
React Native 130600ms 125140ms 127220ms
Cordova 351420ms 357940ms 356740ms

However, test and real life are two different things. Real native apps require a special approach to ensure and increase responsiveness.

Debugging on iOS and Android

Once your Ionic Angular app is integrated with iOS and Android using Capacitor, you can use standard debugging tools to debug your app on each mobile platform.

For iOS:

  • Open your Xcode project and select the “myAppName” target
  • Select the “myAppName” target and go to “Signing & Capabilities”
  • Select your development team, then press “Run” to start debugging on an iOS simulator or an iOS device.

For Android:

  • Open your Android Studio project and select the “myAppName” target
  • Select the “myAppName” target and press the “Run” button to start debugging on an Android emulator or an Android device.

Additionally, you can also use the browser’s developer tools to debug your app while it runs on the device. To do this, you can use the

npx cap serve

command to start a local development server for your app. Then, you can connect to this server from your device using the browser’s developer tools.

Note: Make sure that your device and your computer are on the same network and use the IP address of your computer to connect.

Combine NativeScript, a framework for building native iOS and Android apps using JavaScript, and Angular, a framework for architecting JavaScript applications of all sizes, and you have a powerful software architecture—one that allows you to build mobile and web apps using the same technology stack, and in some cases, the same code.

The NativeScript core team works with the Angular team at Google to ensure NativeScript and Angular are seamlessly integrated. If you know Angular, you’re already ready to develop amazing native mobile apps with NativeScript. With NativeScript and Angular, a single code base (and skillset) can be used to create web apps and native mobile apps with 100% native performance and power. Buttery smooth animations, direct access to 100% of the native platform APIs, it’s pretty amazing.

One skillset. One code base. Three platforms: iOS, Android, and Web.Learn more on the Angular blog.

Using Angular with NativeScript is a snap. From your terminal or command line, just start a new project with this command:


$ tns create my-angular-app --ng

This will create a new NativeScript project with all of the necessary Angular files, folders and settings ready to go. By default, Angular projects use TypeScript, so NativeScript will also handle all of the TypeScript setup and configuration. Learn more about NativeScript and TypeScript.

Once you’ve got your project, it’s time to build your native mobile app! Use these resources to get started quickly:

Our documentation will help you learn the ins and outs of making truly native mobile applications with Angular and NativeScript.

Angular + NativeScript Docs

Angular provides all of the plumbing necessary to create high quality, highly maintainable NativeScript apps. Reuse Angular concepts such as data binding, dependency injection, services, and routing to build native mobile apps.

Work smarter, not harder, right? Use Angular and TypeScript to build “native” apps for the web and, with NativeScript, for iOS and Android. You can even reuse JavaScript npm modules, as well as native iOS CocoaPod and Android Arsenal libraries, directly in NativeScript.

With NativeScript, you can finally create zero compromise mobile apps with Angular that feature truly native UI and performance. Enjoy glorious 60fps without being a CSS or JavaScript wizard, even on Android. Say goodbye to mobile jank.

Tap into the huge Angular developer community, more than 1 million strong, to get extra help, training and reusable code that can be directly applied to NativeScript mobile projects. NativeScript is the way for Angular developers to create native mobile apps.

When starting a new NativeScript Angular project, make sure to use the -ng flag to get the skeleton code.

In your views, do not use self-closing XML like . Instead close all elements with a discrete closing tag:

If you’re planning to add NativeScript to an existing Angular “web” codebase, keep in mind window does not exist in NativeScript, therefore ensure to remove any explicit dependencies on the browser’s global window object in your code.

Find code samples for common app scenarios on the NativeScript Marketplace.

Remember, there is no DOM in NativeScript, so separate layout from business logic for maximal reuse.

We have an entire documentation section on sharing code between web and native apps with Angular. Check it out here.

Photo Gallery!!!

There are three tabs. Click on the Tab2 tab. It’s a blank canvas, aka the perfect spot to transform into a Photo Gallery. The Ionic CLI features Live Reload, so when you make changes and save them, the app is updated immediately!

Open the photo-gallery app folder in your code editor of choice, then navigate to

/src/app/tab2/tab2.page.html

. We see:



Tab 2






Tab 2




ion-header

represents the top navigation and toolbar, with “Tab 2” as the title (there are two of them due to iOS Collapsible Large Title support). Rename both

ion-title

elements to:



Photo Gallery

We put the visual aspects of our app into . In this case, it’s where we’ll add a button that opens the device’s camera as well as displays the image captured by the camera. Start by adding a floating action button (FAB) to the bottom of the page and set the camera image as the icon.

Next, open

src/app/tabs/tabs.page.html

. Change the label to “Photos” and the icon name to “images”:


Photos

Save all changes to see them automatically applied in the browser. That’s just the start of all the cool things we can do with Ionic. Up next, implement camera taking functionality on the web, then build it for iOS and Android.

How is it possible? How does it work? Can it become the perfect budget-saving solution to base your software product on? Read further to see!

Angular mobile app development models: cross-platform and hybrid

Angular is primarily considered a web technology, but in fact, it’s a cross-platform powerhouse, perfectly fit for developing mobile applications. Obviously, decisions about tech stack are not easy. A lot depends on the project’s requirements and the skills of your developers.

Let’s make things clear from the start: you can’t use Angular to create native mobile apps for iOS and Android. If the native approach is your priority, you need to go for native technologies, i.e., Swift/Objective-C for iOS and Java/Kotlin for Android. Still, Angular can help you deliver high-performance mobile apps with great UIs if you couple it with complementary technologies.

Google’s framework is an excellent choice if you’re fine with a non-native approach and want to develop hybrid apps or cross-platform apps. For the latter option, Angular is often used in combination with NativeScript, which acts as a bridge between Angular codebase and the native APIs of iOS and Android.

Instead of using a webview like hybrid applications, NativeScript translates Angular components and code into native UI components and functionality. This means that your app runs directly on the device, providing a native-like user experience.

Ionic, on the other hand, takes a hybrid approach by using web technologies (HTML, CSS, JavaScript programming language) to create mobile apps that run inside a webview. While it provides a consistent and responsive UI, Ionic apps are not truly native since they rely on web technology wrapped in a native container.

Still, Ionic apps offer a consistent user interface and are known for their quick development cycle and broad code reuse.

Angular features

Angular is a framework powered by Google, loved by developers, and used by leading corporations worldwide. Below you will find the benefits that made it famous.

Typescript provides a series of benefits that other JavaScript frameworks cannot match. It is due to the language’s “typing” feature, which streamlines scaling and bug identification. Typescript saves time in the development process and reduces chances for errors by allowing developers to debug while they code.

The Angular team is dedicated to supporting the most important libraries and solutions. With Angular, you don’t have to depend on code from unreliable sources- meaning you can avoid crashes or disruptions in service. Furthermore, the Angular documentation is regularly updated so that users can always access relevant information.

Developers don’t waste time searching for answers to issues since they’ve already prepared everything. Angular unifies architecture and code, allowing you to communicate with people worldwide.

The Angular team supports the majority of libraries. Consequently, you’ll find fewer bugs, better security, and assurance that the package you pick will continue to function soon.

The beauty of Angular is that all the testing tools you need are readily available, so developers can build software more quickly and feel confident making refactors anytime. Another big plus is that developers don’t need to focus on rereading code, as frequent testing helps them reduce errors. It leads to significant time and money savings.

Modularity is essential in current software engineering. It allows for more effortless app scalability and the replacement or reuse of components. Thanks to generic components, coding modules becomes a quick process. In addition, Angular’s lazy loading deferrers module downloads until it’s necessary for the user.

It’s the official Google UI component library for web applications, offering both mobile and desktop support. Using this library, you can build your application much faster because the components are based on the community’s best practices that have been well-tested and improved upon. It will speed up your progress immeasurably. The documentation is also excellent, so you can be confident that you know what you’re doing.

Key features and advantages of Angular for mobile development

With its ability to target multiple platforms simultaneously, Angular is one of the best toolsets for secure mobile app development. Well-crafted Angular-based software doesn’t fall far behind native apps in terms of performance or user experience while offering cost efficiency and a much shorter time to market.

Let’s look at the key features and strengths of Google’s open-source framework.

Code reusability

Angular’s component-based architecture promotes reusing code. Developers can create reusable UI components, services, and logic, minimizing redundant code, speeding up development, and streamlining maintenance and updates. Again: lower costs, faster results.

Convenient CLI

Angular CLI simplifies project setup, scaffolding, and maintenance, ensuring a smooth development process. It comes with various optimization techniques, such as ahead-of-time (AOT) compilation, that minimize bundle size and enhance app performance.

TypeScript

Angular’s use of TypeScript enhances code quality and maintainability by identifying errors at compile time instead of runtime. Such an approach effectively reduces the likelihood of bugs making it to the production phase.

TypeScript also ensures consistency in data structures and interfaces across the app, contributing to maximized performance.

Native app-like experience

With technologies like NativeScript and Ionic, Angular mobile apps can be transpiled into native code, leveraging the capabilities of a mobile device for a seamless user experience.

Both Angular frameworks provide the means to create efficient and visually appealing near-native apps, all while benefiting from the productivity and code reusability of the Angular ecosystem.

State management

Angular provides robust solutions for state management, i.e., handling application inputs across multiple related data flows. They include built-in support for reactive programming through RxJS and NgRx for more complex state management scenarios.

State management tools facilitate controlling the application’s state and managing numerous interactions, contributing to the responsiveness, maintainability, and scalability of Angular mobile apps.

Progressive Web App (PWA) support

Angular offers strong support for progressive web application development with features like service workers and the @angular/pwa package, simplifying PWA implementation.

Angular service workers (JavaScript middleware acting as a proxy server between an app, a browser, and the network) provide offline support, background synchronization, and efficient caching of assets and data.

Additionally, Angular’s responsive design capabilities make it easier to create PWAs that adapt seamlessly to a user’s mobile screen size.

Step 4: Integrate With Electron

To be able to run your Ionic Angular app on a desktop operating system, you will need to integrate it with Electron. We can accomplish this using the @capacitor-community/electron package, which is a community-maintained Electron plugin for Capacitor.

To install the plugin in your application, run the following command in the terminal:


npm install @capacitor-community/electron

You will also need to register the plugin in your

capacitor.config.json

file by adding it to the

plugins

array:


{ "plugins": { "Electron": { "path": "./node_modules/@capacitor-community/electron" } } }

Then you can use the following command to add the Electron platform to your project:


npx cap add electron

To run the app on the electron, you can use the command:


npx cap open electron

This will open the electron development environment and you can run the app and debug it.

Note: The @capacitor-community/electron package is a community-maintained package and may not be as stable or feature-complete as official Capacitor plugins. It’s recommended to test your app thoroughly before deploying to production.

In conclusion, with the help of the @capacitor-community/electron package, you can easily integrate your Ionic Angular app with Electron and run it on Windows, Mac and Linux. With this Electron support and the Capacitor support for iOS and Android, you are able to provide a much more comprehensive solution for your end-users and increase the reach of your app.

What is Angular?

Angular is a comprehensive framework for building web applications quickly and easily. It offers programmers a set of ready-to-use tools, libraries, and code snippets that can be supplemented with custom code. Angular has an efficient architecture and comes with pre-built components that make development faster by providing general functionality that can be customized to meet specific needs. It saves engineers from reinventing the wheel whenever they encounter common problems in different applications.

Google introduced Angular in May 2016, making it a relatively young technology. Since then, numerous new versions have been released; the framework has become one of the most popular among application developers. According to the definition, Angular’s primary goal is to make developers’ lives easier.

To install the plugin in your application, run the following command in the terminal:


npm install @capacitor-community/electron

You will also need to register the plugin in your

capacitor.config.json

file by adding it to the

plugins

array:


{ "plugins": { "Electron": { "path": "./node_modules/@capacitor-community/electron" } } }

Then you can use the following command to add the Electron platform to your project:


npx cap add electron

To run the app on the electron, you can use the command:


npx cap open electron

This will open the electron development environment and you can run the app and debug it.

Note: The @capacitor-community/electron package is a community-maintained package and may not be as stable or feature-complete as official Capacitor plugins. It’s recommended to test your app thoroughly before deploying to production.

In conclusion, with the help of the @capacitor-community/electron package, you can easily integrate your Ionic Angular app with Electron and run it on Windows, Mac and Linux. With this Electron support and the Capacitor support for iOS and Android, you are able to provide a much more comprehensive solution for your end-users and increase the reach of your app.

Step 4: Integrate With iOS, Android, and Electron

Assuming you have the prerequisite mobile SDKs installed from above, you can now integrate these into your project.

To build your Ionic Angular app for iOS, run the following command in your terminal:


npx cap add ios npx cap open ios

To build your Ionic Angular app for Android, run the following command in your terminal:


npx cap add android npx cap open android

To run your app on iOS or Android, you can use the Ionic DevApp, which is a mobile app that allows you to test Ionic apps on your device without having to go through the process of building and deploying.

Prerequisites

Before we begin, it’s important to note that you will need to have Node.js and Node Package Manager (NPM) installed on your computer. If you don’t have these tools installed, you can download them from the official Node.js website.

Also, to integrate your Angular app with iOS and Android, you will need to have the corresponding SDKs (Software Development Kits) installed on your computer. For iOS you will need Xcode (which means you will need to be working on a Mac), and for Android you will need Android Studio.

Apps You Can Build With Angular

Angular may be a valuable tool for modern web application development. Let’s take a look at some of the sorts of apps that are possible with Angular:

  • Single Page Applications (SPA)

Due to the framework’s routing and data management features, single-page applications based on Angular platforms have quick load times.

By using Angular to build your spa, you are provided with fantastic UI support and unparalleled performance that will result in a lag-free, dynamic user experience. SPAs, or single-page applications, have surged in popularity due to the excellent user experience compared to standard multipage applications. With Angular’s easy routing and data management, it has become simple to construct a SPA that loads quickly and provides users with a great experience.

Angular mobile and web applications have high-class, secure, scalable software, which is crucial for large enterprises and corporations like Google, YouTube, or Microsoft. In addition, Angular has an MVC architecture and code reuse, which reduces Angular mobile app development time.

Angular is a fantastic tool for building mobile apps. Reusing front-end code between mobile and web devices makes creating Angular mobile app development easier in less time. Cross-platform web applications are frequently developed using Angular frameworks.

You can create high-end mobile applications by combining Angular with NativeScript. Another great option for creating hybrid apps is to combine Angular with Ionic, which provides an almost native experience while allowing most of the code to be shared between iOS and Android.

  • Progressive Web Applications (PWA)

Progressive Web Apps have changed the game regarding mobile web applications. By providing functionality similar to a native app, they offer users a great experience while ensuring that experienced developers can quickly adapt the application to different screen sizes and ensure fast loading times. Plus, with offline support and features that mimic the look and feel of a real app, progressive web apps are quickly becoming the standard for mobile development.

Creating a PWA application with Angular opens the door to sophisticated capabilities such as responsive design, mobile-like functionality, and an unrivaled offline experience.

Of course, PWAs require additional work and poisoning programmers with appropriate experience.

  • Server-side Rendered (SSR) Apps

Angular makes it easier to create an SSR, which improves and speeds up performance. Apps web applications can be displayed in a browser or on a server. When the server prepares or pre-populates custom user data, loading times are reduced significantly.

For SSR applications, Angular improves page load speed and site traffic on Google’s search results page (SERP), making it the preferred option for many developers.

Suppose animations are the key distinguishing feature of your software development project. In that case, you must consider using Angular for the development process.

Engaging, surprising animations are the features of the EdTech application and all educational platforms. Of course, they can also be used in other industries because well-developed animations steal users’ hearts, which translates into market success.

No matter your organization’s size, Angular is the best choice for building applications across domains and industries. Its high performance, robust features, ready-to-use components, and extensive libraries create a powerful support system for all types of businesses.

The features and scope of the project will ultimately determine which software to choose. Angular provides all the necessary features, but it is also powered by Google and has a strong online presence within its community.

What is Angular Native made of?

Angular Native is not a brand name. It’s more of a bundle of two technologies, Angular 2 and NativeScript. We are going to see how it works, exemplify it with real cases, and cover strengths and weaknesses of both platforms.

NativeScript is a platform developed by Telerik (currently Progress) for cross-platform mobile app development, which is backed by Google at the moment. The latest releases of NativeScript are marketed not as a standalone technology, but in an inseparable bundle with Angular 2. This allows to write apps for mobile, desktop and web.

But now let’s proceed to each of the two parts.

Summary

Due to its advantages, Angular enjoys a large population among developers. Since Angular was designed to build dynamic web applications, it is most commonly used in single-page or SPA applications. It can also be used in mobile applications, proven by giants such as Microsoft and Google.

As a mobile & web application company, we are happy to share our knowledge and advise you on the choice of a language tailored to the needs of your project.

Performance in real apps

In order to ensure high responsiveness in native apps, flows are used. All business logic, all calculations are in a separate UI flow, which helps the app react to any interaction with the end user instantly.

Here is an interesting fact about ReactNative—the reason why it fell behind NativeScript in tests. Both technologies have different realization of architecture. In NativeScript, interaction with native code is synchronous. In ReactNative, JS code is in a separate flow, and interaction with the native functionality is asynchronous—there is no need to take care of it.

This illustration is taken from the London React keynote. This is why they have a lapse in performance at the moment when flows in ReactNative transmit data between each other.

The end-user does not care how many milliseconds it takes to run an operation. They need an app that looks great, works fast and does everything that has been promised. In this regard, flows become the killer feature of ReactNative. NativeScript solves this problem differently, supports standards, and suggests the use of Web Workers in apps.

They have the same APIs as browsers and the same functionality, with a subtle difference: if you work with Web Workers in the browser, there will be no access to DOM. Access to UI is granted; however, its use becomes an obstacle to all flows. Web Workers are the optimal solution here.

Angular in Angular Nativestandard Angular

It should be noted that Angular Native isn’t really different from the usual Angular 2, except for templates:

They have no HTML tags, things you got used to in the HTML layouting. Views and layouts are native here.

In ReactNative it’s necessary to use JSX, which leads to duplications of code of components for different platforms. As opposed to that, in Angular Native you simply have different templates for different platforms, for cases of need. Otherwise, NativeScript provides cross-platform abstractions over native views.

We should mention a major difference on the platform level. In ReactNative app development, all layouts are based on the FlexBox positioning algorithm. In NativeScript, there are simpler cross-platform abstractions for implementation of positioning. It means that you have options for every case.

Another thing that helps in NativeScript development is automated use of specified code for every platform.

*.android.* *.ios.* *.-common.*

There are magic postfixes for that. When they are used, NativeScript utilizes platform-specific code. This related to templates and JS code.

Conclusions

  1. First and foremost, the platform is product-ready.
  2. But keep in mind that it’s required to know the specifics of the platforms.
  3. Async does not equal flows. If complex calculations are required, Web Workers should be used.
  4. Keep an eye on official bugs. We had a case when an Android app was lagging, and within 4-5 seconds after transition to another screen, the app stopped responding altogether. The official repository had an issue, and we found a solution in a matter of minutes.

How NativeScript works

A rather simple idea like “to write a native app in JavaScript” can conceal substantial issues. The main question here is, how do you define a native app? There are two possible answers:

  • 100% native functionality in your app
  • 100% native performance in your app (including UI)

It is important to differentiate these two criteria clearly.

Let us start with 100% native functionality. If we speak about PhoneGap, we speak about an app with an in-built web browser, which becomes the environment for your JS-based app. JS code runs in this browser and gets limited access to API via Cordova plugins. Thus, if you need some element of native functionality, you need a plugin. The good news is that this plugin might already have been written and made available for use.

In case of Xamarin or NativeScript, your code gains full access to native API. How does it work?

The implementation is different for different platforms:

In the code, everything looks way simpler:

var file = new java.io.File(path);

This is a valid line in NativeScript, when a variable file is created and a native object java.io.File is assigned to it. Here is the description of the steps that follow, taken from documentation:

  • The virtual machine executes the JavaScript code.
  • Binding defines corresponding call methods from the native side.
  • The transfer service transforms the JavaScript string into object java.lang.String.
  • The outcome of the function call is a custom JavaScript object—it works as a proxy for a native object java.io.File, created on the Android side. When a method called for that proxy, it is delegated to the underlying native object instance.

However, it works when the program is launched; the virtual machine executes JS code – V8 for Android and JavaScript Core for iOS. These are two different virtual machines with different mechanisms and interactions with native device API.

But the general idea of how it works remains the same for all platforms. We use the mechanism of metadata, which contains signature for a native method that should be called when you execute JS code.

This means, whenever something new appears in the native SDK, the developers of NativeScript write a method that is called on the native side and a corresponding method signature on the JS side in the metadata file. It’s simply a table. When you get a new SDK, they add a new entry for work with this method. This allows to ensure support for the so-called day zero. Within 5-6 hours from the release of the new SDK, an update of NativeScript is released, which already supports this functionality. The developer doesn’t have to rewrite anything. Metadata, which allows to use the reflection mechanism between JS and native code, is used for building required interfaces at the moment of app launch. It sets up the correspondence between calls of native objects and the array of JS names. This is the reason why the startup time in NativeScript is longer than in its rivals. However, version 2.5 promises “drastically improved startup time.”

The evolution of Angular: from AngularJS to Angular

Angular is frequently mixed up with AngularJS due to the name similarity. In reality, both frameworks are fundamentally different in architecture and capabilities. Plus, AngularJS was discontinued in January 2022 and is no longer supported. Nevertheless, both technologies have more in common than the name.

AngularJS, also known simply as Angular 1, made its debut in 2010 under the stewardship of Google. It was a groundbreaking JavaScript framework designed to simplify web app development. AngularJS pioneered two-way data binding, enabling sharing data between a component class and its template.

It also prioritized declarative programming – over the imperative approach recommended for business logic – in building user interfaces and joining software components. Overall, it helped enhance user experience while heavily reducing the amount of boilerplate code developers had to write, saving time and costs.

The framework quickly gained popularity and became a cornerstone for building dynamic web applications. However, in the tech industry, things change fast. Soon, AngularJS started to show limitations related to building large-scale applications. Performance was also far from stellar.

A few years into its evolution, the framework struggled to keep pace with modern web requirements. As hurdles piled up, Google’s Angular team had no other option but to rethink their approach. In 2016, the company released Angular 2.

The new iteration was not an incremental update but a complete rewrite of the framework. It successfully addressed the shortcomings of AngularJS and provided developers with a more robust and flexible toolset for building exceptional user interfaces.

One of the key differences between Angular and AngularJS is the language used. While AngularJS relied on JavaScript, Angular adopted TypeScript, a statically typed superset of JavaScript. TypeScript brought strong typing, enhanced tooling, and improved code maintainability to the table, making Angular applications more robust.

Another vital update is the change from two-way data binding to one-way data flow. Angular introduced a unidirectional data flow model, making it easier to manage the state of applications and reducing unexpected side effects. This change helped developers build more predictable and maintainable code.

Angular 2 and its later versions (an interesting tidbit is that the number 3 was left out due to a router’s package versioning misalignment) were structured as a collection of reusable components, emphasizing code reusability.

Since its “refurbishment,” the framework has been heavily focused on performance optimization, aided by features like Ahead-of-Time (AOT) compilation or change detection mechanisms. These and other refinements helped to deal with the predecessor’s major drawbacks, making Angular web and mobile applications faster and more efficient.

NativeScript + Angular - Build Real Native Mobile Apps for iOS and Android
NativeScript + Angular – Build Real Native Mobile Apps for iOS and Android

What it looks like in the code

Calls of native methods in the app look like this:

// iOS var array = new NSMutableArray(); array.addObject(new NSObject()); // Android var context = …; var button = new android.widget.Button(context); // “My Button” is converted to java.lang.String button.setText(“My Button”);

In the first example, you work with a native array of objects in iOS. In the second one, you create a native button and assign a text to it. This is the most fascinating thing. Even in NativeScript all plugins for interaction with native functionality, e.g. accelerometer, are written in pure JS.

The following code was taken from a real project. It shows how it’s possible to disable selected colors for iOS in NativeScript ListView:

var listView = this.page.getViewById(“list_view”); listView.on(ListView.itemLoadingEvent, (args: ItemEventData)=> { // disable select colors if it iOS if (args.ios) { args.ios.selectionStyle = UITableViewCellSelectionStyle.UITableViewCellSelectStyleNone; } });

What We’ll Build

We’ll create a Photo Gallery app that offers the ability to take photos with your device’s camera, display them in a grid, and store them permanently on the device.

Highlights include:

  • One Angular-based codebase that runs on the web, iOS, and Android using Ionic Framework UI components.
  • Deployed as a native iOS and Android mobile app using Capacitor, Ionic’s official native app runtime.
  • Photo Gallery functionality powered by the Capacitor Camera, Filesystem, and Preferences APIs.

Difficulties for software developers:

• Command-line interface. The problem is that simulators don’t always launch on the first try. There’s a large stack that loads for quite a while.

• You cannot put a container in a view. That’s the reason why emulators may crash during composition of a component structure from standard layout templates.

• Unfortunately, currently there is no inspector that would help check the layout. It’s native development, and components are different for every platform (e.g. listview for Android and UI table for iOS).

• No option of using standard HTML elements in layouts. There is no HTML here. Stylization of off-the-shelf templates is hindered by the impossibility to see basic CSS properties. No wonder—native development is less flexible. It provides fewer opportunities for stylization and customization of elements than web development.

Now let’s proceed to the positive impressions:

Command-line interface, off-the-shelf animations, keyframe animation, off-the-shelf layout elements, which are rendered according to the specifics of every platform.

Now, what were the negative impressions?

First of all, NativeScript development is less convenient than web development. It does not have the set of tools as broad and convenient as the one for web development. Stylization with a custom design is also problematic.

Here is an opinion of a developer who was not involved; he simply sees the NativeScript-based apps on the market:

App demos are regularly studied by developers on framework websites.

ReactNative gains the upper hand because it’s asynchronous, and the developer does not need to understand the specifics of native development. However, it will never provide you with the same stylization without a native developer, as opposed to Angular Native. The latter is closer to native rather than the web.

We have a test case: a project called Property Cross, made for evaluation of different platforms for cross-platform development. Currently, we have an app there, which utilizes an older version of NativeScript (1.7, as opposed to the current 2.5). Feel free to visit GitHub and check the implementation of the same app with a variety of frameworks.

You can see animations, transitions, rounded images, and stylization of native controls.
