Angular 9: Introduction and features

In this Blog, we will gonna see a brief introduction to Angular 9. The Angular 9 is launched on Feb 7, 2020. So the versioning change from 8 to 9. Angular version 9 is an evolutionary release and it includes many new features and bug fixes.

In this blog, we going to discuss the following topics:

– Complete Development with Angular

– Angular View Engines Understanding

– Long-standing problems solve by Angular Ivy

– Angular Ivy and Mobile compatibility

– The Future of Angular

Angular is an outstanding open-source framework for web and mobile application development. which maintained by Google, Angular is a framework with a complete set of tools which require to build the application. Angular follow the proper roadmap, Angular release a new version every six months with new features and bug fixes. The Google team works hard and Dedicatedly maintains Angular, so API will not need to change like as before in Angular 1 & 2 we have faced drastically change in API. That’s a great thing, Which keeps up-to-date the things with the best practice and advanced features supported by JavaScript and TypeScript.

In this blog, we will discuss the Ivy compiler in detail, we will discuss the Ivy and why Ivy is important features for angular. The spoiler alert is solved the different problem with large bundle and application performance. we also discuss different features like internationalization support and selector less binding

Java Script Performance and Bundles

We cant feel difference at the run time. The angular runtime performance is good but loading time is longer because the simple app is also large.

The JavaScript bundle also drow our attention to another problem. We can learn more things with the angular because angular provides many built-in developers tools. While the other JS framework libraries are focused on components.

Understanding of Angular View Engines :

Before the release of Angular 8, The angular framework relied on ViewEngine for the render and build code in the browser. The Angular component is written using the typescript language. The typescript is a set of JavaScript. We can use the compiler to render the TypeScript. angular relied on view-engine for transpiling typescript code into JavaScript.

Angular ViewEngine can take the Component and Templates, and translate them into the regular JavaScript and HTML so a browser can interpret and display them.

Long-standing problems solve by Angular Ivy :

Ivy is the most significant feature that was released with Angular 8. It acts as an internal build and pipeline render. A renderer is a kind of engine that takes the instructions which we input into the Angular component. after that, it translates them into instructions that change the Document Object Model (DOM).

Changing the view engine with Ivy it’s not replaced our way of work with Angular. but its definitely an impact on the generated code.

Angular 8 preview allows the user to play around with Ivy But in Angular 9 Ivy is the standard renderer. The purpose of Ivy is a more efficient renderer or easier to implement. It allows us to ship less code because it requires fewer instructions.

Ivy generates even smaller bundles of JavaScript and Ivy solves the drawbacks of Angular’s bundles. Ivy will be a game-changer because it takes Angular applications in terms of performance and scale to a whole new level.

Ivy doesn’t change the way you use Angular, but it does change the way the app is created. The Angular team has concentrated on projects such as modern JavaScript’s differential initialization, which was shipped with Angular.

Angular Ivy and Mobile compatibility

The world’s half website traffic came from Smartphone devices. A large number of such mobile devices view web pages from areas suffering from slow internet connections.

The developers can rebuild existing apps to reduce the size of downloadable assets and increase the mobile user experience, but these changes can be challenging, costly, and bring unforeseen risks to their projects.

Through, reducing the size of JavaScript packages, Ivy is becoming a welcome improvement for developers who want to speed up the initialization of applications.

The Future of Angular

Angular 9 provides a better developer experience. with an all-new Angular 9 Developer has a clear project structure and a clear syntax.

Possible changes will be introducing in Angular in the near feature.

The Angular team had indicated that there are no huge changes are required in the API. Will there be more deprecations, and perhaps an alternative form of part creation? An enhanced experience with the developers is always something to hope for.

Maybe we’ll spend more time in the future developing components and directives, and less time trying to put them together.

Hope this article helps you in introducing Agular 9 and its features !!
