Angular 9 New Features

What’re the Angular 9 New Features?

We all are familiar with the most popular open-source platform i.e Angular for web and mobile application development.

It is built by Google and has evolved over the years into an ideal front-end development platform that provides all the resources and components needed to build a web app.

For developers across the world, Angular is the first choice for front-end development. It is becoming highly major for the team to fix bugs and modify the already existing framework.

On 7 February 2020, Angular has finally released its latest version i.e Angular 9. We all know about Angular is the most popular JavaScript framework, primarily responsible for developing front-end desktop web apps or single-page applications, giving rise to every AngularJS Development Company in the world.

So, what’s new about Angular 9? All existing drawbacks have been modified in this new update. A lot of factors have been affected by the previous versions of Angular.

What’s new with Angular 9?

  • Compiling Ivy applications is the norm in Angular 9 
  • The Angular code is compiled Ahead-of-Time (AOT). It ensures that the Angular AOT compiler must compile and run all the HTML and TypeScript present in your code into JavaScript before your browser downloads it.
  • Angular 9 is provided by TypeScript 3.7. Some lower versions are not provided.
  • tslib (TypeScript runtime library) has now become a peer dependency rather than a direct one. Previously, this library would be built automatically, but now you’re going to have to add this directly using npm or yarn.

Let’s have a detailed of the view on the latest features:-

JavaScript Bundles and Performance

Ivy has now become an Angular 9 standard renderer with more performance and ease of implementation. 

The problem of Angular bundles is solved by Ivy, as it generates much smaller JavaScript bundles and ivy is expected to deliver one level-up output to Angular 9.

Faster Mobile Apps

Mobile phones pick up half of the traffic on the website globally. A considerable number of users come from places where Internet connections are slow.

It is therefore important for Angular 9 developers to redesign and reduce the size of downloadable files and increase the experience of mobile users.

By reducing the size of the JavaScript packages, Ivy opens a forum for developers to speed up the application.

Betterment in Debugging

In Angular 9, you’re not going to have to debug through the system, but you can do it on the feature itself, which lets you debug the code instantly.

Improved CSS class and style binding

Ivy compiler and runtime handle style in a predictable manner. Under previous versions, if the specification had conflicting style concepts, such styles would override each other.

With this Angular 9 functionality, you can manage styles through a simple, consistent order of precedence that does not depend on timing.

Enables the AOT compiler to default 

In the new IVY architecture, we see a significant change in the compiler’s performance. It means that the AOT builds are going to be noticeably faster.

Changes in compiler and runtime would no longer require entryComponents. andng serve. 

Typescript 3.7 Support

The update of Typescript 3.7 in November 2019 gave a big upsurge to a new angular 9. Corner 9 is revised to function with TypeScript 3.6 and 3.7.

The null coalescing and optional chaining feature of Typescript 3.7 helps to keep the environment in sync.

Enhanced Internationalization (i18n) 

Internationalization is an important feature of Angular 9. The new solution appears with Angular 9 which balances most of the drawbacks without losing efficiency, and Ivy makes it easier to carry out the entire process.

Advancement in Angular Forms

The advantage of angular applications in Angular 9 has come with a few forms of changes. The <ngForm></ngForm> is not a functional selection of the refreshing Angular form. Now with the new version of <ng-form></ng-form> is used.

Language service improvements

One such code is the Angular Language Service, which adds many features to the VS Code. This helps us to write our Angular code. Other extensions include useful Angular snippets, ESLint extensions, and debugging extensions.

In addition to increased performance and stability issues, many long-standing bugs have also been fixed in this Angular 9 feature.

Conclusion

The main purpose of Angular 9 is to make the Ivy compiler available for all the applications and the main advantage of Ivy is to decrease the size of applications for better user experience.

With the modification in Angular 9, Angular developers can now understand a clearer structure and syntax for their projects. With this update, developers will breathe relief as they can harness the power of Ivy’s renderer to create versatile and faster Angular applications.
