Angular 8: The Improved Features and Functionalities

Released in the year 2009, AngularJS is one of the most popular front-end JavaScript frameworks for web app development. AngularJS lacked many essential features that were being offered by other JavaScript frameworks in the market. Hence, Google launched Angular, an open-source JavaScript framework, with much more advanced and additional features as compared to AngularJS like AOT, tree-shaking, etc

After the success of Angular, Angular 2, Angular 4, Angular 5, Angular 6, Angular 7 were released, with improved features and now, it has been around 10 years, in 2019, the Angular community has released its latest version Angular 8 with an impressive list of changes and improvements including the much-awaited Ivy compiler as an opt-in feature. Seeing the amazing features, which this framework offers, there is a huge demand for Angular development services among both users and developers. 

To upgrade your Angular 7 web app framework to Angular 8, you just need to follow the following command:-

ng update @angular/cli @angular/core

In this blog, we will discuss the potential features of Angular 8.0, let’s dive right in!

What’s new in Angular 8.0

Angular is written in Typescript, an open-source programming language. It continues to evolve, and the latest major release includes features that focus on performance, stability, and tooling. Angular 8 version allows web developers to create an interactive client-side application. Its advanced feature makes it to be used widely in big companies like Google, Facebook, Paypal, etc.

Angular 8

Let's have a look at some of the highly anticipated features: 

Angular Ivy

Ivy is a major change in Angular history, it uses incremental DOM and is angular rendered. It changes how the framework internally works, without changing our Angular applications. The Ivy project is rewriting the Angular compiler and runtime code. It is a major update of Angular 8. 

Angular team has planned to make an Ivy renderer compatible with existing Angular applications so that you won’t have to make major changes once it is finally released. To use Ivy in your project, you can instruct the Angular CLI to enable Ivy in your project using the --enable-ivy switch:

$ ng new angular-project --enable-ivy  

Lazy Loading

The Angular framework has adopted the more common dynamic import syntax that relies less on parsing class names from strings and enables editors and IDEs to check that you’re importing the correct items. It helps in decreasing the size of large files by lazy loading it. 

Dynamic import syntax understands the mistakes and detects it, which helps to eradicate errors and make the route integration clean. Hence, TypeScript and linters will be able to detect missing or misspelled modules better. Angular 8 can collect commands and build the speed that developers want to improve in the future.

Support for TypeScript 3.4

It is now mandatory to upgrade to TypeScript 3.4 in the Angular 8 update. This has brought many benefits as the TypeScript team always introduces new features in every new release. For a bug-free code, you need a check on the program, which is done with the help of the compiler that TypeScript offers to verify it. It is created and backed by Microsoft. The Angular developers leverage the Typescript for building large-size applications.

Dart-sass for Sass Files

Dart Sass is switched as default Sass compiler in Angular Cl 8. It is well-known as it is the fastest also compiler might be slightly stricter. It would be correct to say that Angular CLI has ditched node-sass for dart-sass to create your Sass files. This new feature offers a basic template for your new web worker for you to worry less about boilerplate syntax and facilitates writing the code very quickly, which you want to run on a background thread.

Changes in ViewChild and ContentChild

Any directive, component, and element which is part of the component template is named as ViewChild. Whereas, any element or component which is projected inside is named as ContentChild. They were implemented so components could request elements that were not in a structural directive, such as ngIf or ngFor.

Bazel – A New Hype

Bazel is created and maintained by Google. It can work across all the languages. The team is trying to integrate Bezel in the toolset to enable Angular developers to perform faster incremental builds on large projects. It enables you to declare tasks with clear input and output and allows you to run only the necessary ones. Hence, if you want to build CLI apps, Bezel is your key. 

Differential Loading

It is a new feature of Angular 8 that lets you create two different production bundles of your app. It has proven to be a performance booster in the application. If you use ng upgrade then, Angular will update your tsconfig.json so that you can reap the benefits of it. 

After this, Angular verifies whether to take advantage of Differential Loading by allowing CLI to keep an eye on the target JS level of your tsconfig.json. It streamlines the process by integrating CLI ext. Angular CLI will now contain separate bundles for legacy JavaScript (ES5) and modern JavaScript (ES2015+).

Builder and Workspace APIs

New APIs allow you to create custom build and deployment commands using hooks into the familiar ng build, ng test, and ng run commands. Angular 8.0 makes modifying and reading the file a lot simpler with new APIs. 

It allows you to open and work with the workspace defined in your angular.json file, which should reduce the amount of manual manipulation required to perfectly configure your project. The latest AngularFire, for instance, adds a deploy command, simplifying the process of build & deploy to Firebase.

Web Worker Support

To improve the parallelizability web workers are included to produce bundles that help increase the performance. Angular 8.0 is thus adding building support to CLI which provides one bundle for every web worker. The updated files include a basic template for your new web worker so you can worry less about boilerplate syntax and focus on writing the code you want to run on a background thread.

If your program is not responding and not loading the data you can depend on Web Worker. Angular CLI can help you create Web Worker by the following thing:

ng generate worker n-queens

Final Words

The present and future of the framework appear bright with Angular 8. It is somehow familiar among developers and most commonly adopted by enterprises. Ivy is the prominent feature of Angular 8 that has gained much attention. The latest version looks quite promising and we look forward to leveraging all of its features for building modern web applications in the near feature. 

So, if you are wondering whether to upgrade to Angular 8.0, the answer is yes. With every release, the framework is getting smoother and smoother. After going through the article, if you would like to transform, then you can contact the Angular JS development company that can help you build your application just the way you dreamt.
