What’s New with Angular 8 Features?

Angular community has released its latest version which is known as Angular 8. If you are familiar with previous version of Angular, it will not be difficult for you. You can easily upgrade your Angular CLI to Angular version 8. In this article, we will cover the most important new features of Angular 8.

First of all let’s see what is Angular?  

Angular is also referred to as AngularJS or Angular.js is an open-source desktop and mobile framework for handling the front-end app development process. This javascript-based framework was originally developed as a complete tool and admired for allowing developers and designers to interact with both front-end and back-end modes of an application.

What is Angular 8?

Angular 8 is a client-side TypeScript based framework which is used to create dynamic web applications. It is very similar to its previous versions except having some wide features. Compared to Angular 7, there are a whole lot of performance and workflow improvements in the latest version of Angular 8.

Angular Version History

  • Angular version 1.0 which is commonly known as AngularJS was launched in 2010 by Google.
  • Angular 2.0 was released in September 2016
  • Angular 4.0 version was introduced in March 2017
  • Angular 5.0 was released in November 2017.
  • Angular 6.0 version was released in May 2018.
  • Angular 7.0 version was released in October 2018.
  • Angular 8 version was released in May 2019.

What is New with Angular 8.3?

A new deploy command added to Angular CLI

Angular CLI has many commands that make development quick such as ng new, serve, test, build and add. Now a new ng deploy has been introduced which allows developers to deploy their final app to the cloud with a few clicks from their command-line interface.

Before using the command, you need to add a builder that provides your project with the capability to deploy to a specific hosting provider. For example, for Firebase, you first need to run the ng add @angular/fire command which takes care of all the configurations you need for Firebase. After that, you can run the ng deploy command which creates an optimized production build and upload it to the web.

Increased speed in production builds

Angular 8.0 introduced differential loading which is a cool feature that allows Angular CLI to produce two production bundles, one for modern browsers targeting ES6+ and one for legacy browsers targeting ES5. As a result, the ng builds –prod takes twice the time needed for building a project. In Angular 8.3 optimized the command as follows:

The ES6+ version is built first,

Next, ES6+ bundles are transformed to ES5, instead of rebuilding the project from scratch.

A new design of the home page of the Angular project

If you have created and served a project with the latest Angular 8.3 version, you’ll notice a nice looking interface with helpful links and common commands to start your development journey:

What’s New with Angular 8 Features?

 

Angular 8 was released and these are the latest and most significant features:

By Default Differential Loading

At the time of building applications, Angular will create a separate bundle of polyfills which completely depends on your browser list file. Angular 8 is being introduced with this amazing feature which decreases the bundle size and helps developers build highly compressed applications. The feature works by building additional files with polyfills that are precisely injected through nomodule attributes.

Lazy Loading with Dynamic Imports

The feature of Lazy loading is custom and was built for the developers’ toolkit since the birth of Angular. With the Angular latest version, this feature has completely being deprecating the loadChildren: string syntax which so far supports to load the application modules lazily.

Before update the syntax used to run like:

loadChildren: ‘./lazy/lazy.module#LazyModule’;

After Angular 8 feature introduction, the module be like:

loadChildren: () => import(‘./lazy/lazy.module’).then(m => m.LazyModule)

Support for Web Worker Bundling

Web worker in this latest Angular version is being added as the best alternatives when you’re into CPU-intensive tasks. This feature speed-up the application performance along with improving parallelizability. Web workers perform by writing the code off the main application thread and offload it to a separate background thread.

Improved Support for TypeScript

Angular 8 is in the market which also welcomed TypeScript 3.4 and allows updating the application’s TypeScript version without trouble and failing.

This angular version feature is known as the update of dependencies which provides an outstanding way to synchronize it with the current ecosystem. This feature also ensured greater benefits when developers wish to generate easily readable and clean JavaScript codes.

Use of SVG as A Template

With Angular 8, developers can now use SVG files as a template. Earlier, they only had the access or option to use inline HTML or external HTML syntax as a template. It’s the best feature that app builders can utilize to save a lot of time and effort.

Ivy Rendering Engine

Ivy is basically the prime feature of this latest Angular version release. This feature is still in the experimental phase and if anyone wants to use it in an application, he can use it with enable-ivy flag set to true. Right now, it’s not fully functional but, yes one can use it to improve View Engine functionality.

One can enable Ivy by in an existing project by setting enableIvy option in the angularCompilerOptions in the project’s tsconfig.app.json.

“angularCompilerOptions”: {“enableIvy”: true}

Further, you can create a new app with a new Engine by using the below syntax.

$ ng new my-app –enable-ivy

Builders API

This new version of the Angular framework allows developers to use Builders API, which is also known as Architect API. Here, Angular 8 uses builders for a few main operations like:

Serve, build, test, lint, and e2e. The best part is that you can see the builders used in your angular.json file.

Bazel Support

With Angular 8, it’s now possible to create a CLI application easily and precisely. It’s because Bazel is here with a new Angular version update. This feature was developed and used by Google to build a tool that can function with different language inputs.

You can add Bazel support by using the given command line.

ng add @angular/bazel

Creating a new app has now become easier with Bazels. Use the code below to get it right.

$ npm install -g @angular/bazel

$ ng new my-app –collection=@angular/bazel

Enhanced Support for Service Worker

Service worker was extremely running in Angular 7 and have now been updated with exceptional potential to build PWAs with exceptional improvements.

  • The best improvement is SwRegistrationOptions which has been added to the latest Angular version.
  • The next is that this feature provides support to multiple apps in one domain.

Support for Location AngularJS API 

Here, with the location service feature, the Angular team initiated to offer enhanced support to all the developers who are using AngularJS framework and want to upgrade to Angular. In the Angular 8s, the community has added support for a $location service when you upgrade to the new version. You will be given a new package angular/common/upgrade.

How to Update From Angular 7 to Angular 8?

Advantages of angular 8

  • It offers clean code development
  • Higher Performance
  • An angular framework can take care of routing, which means moving from one view to another is easy in Angular.
  • Seamless updates using Angular CLI (Command Line Interface).
  • It allows the ability to retrieve the state of location services.
