Angular v8 is Released

Angular v8 is Released

Angular's 8.0.0 release is here! This is a major release that brings some nice features.

Let's talk about some of the changes.

How to update to version 8

Visit update.angular.io for detailed information and guidance. For most developers, one command should take care of this update:

ng update @angular/cli @angular/core

Differential Loading by Default

Differential loading is a process by which the browser chooses between modern or legacy JavaScript based on its own capabilities. We now take advantage of this by default by performing a modern build (es2015) and a legacy build (es5) of your application. When users load your application, they’ll automatically get the bundle they need.

If you use ng update, we update your tsconfig.jsonfor you to take advantage of this. Our CLI looks at the target JS level in your tsconfig.json to determine whether or not to take advantage of Differential Loading.

{
  "compilerOptions": {
  …
  "module": "esnext",
  "moduleResolution": "node",
  …
  "target": "es2015",
  …
},


When target is set to es2015, we generate and label two bundles.

At runtime, the browser uses attributes on the script tag to load the right bundle.

<script type="module" src="…"> // Modern JS

<script nomodule src="…"> // Legacy JS

On angular.io we saved over 40kB of initial bundle size for modern browsers. From the community we’ve heard that applications generally save 7–20% of their bundle size, depending on the amount of modern JavaScript features they take advantage of.


The bundle size on angular.io shrunk by about 41Kb

Route Configurations use Dynamic Imports

We highly recommend you lazily load parts of your application using the router. This is accomplished by using the loadChildren key in your route configuration.

Previously this looked like:

{path: '/admin', loadChildren: './admin/admin.module#AdminModule'}

This syntax was custom to Angular and built into our toolchain. With version 8 we’re migrating to the industry standard dynamic imports.

Now this will look like:

{path: `/admin`, loadChildren: () => import(`./admin/admin.module`).then(m => m.AdminModule)}

This will improve the support from editors like VSCode and WebStorm who will now be able to understand and validate these imports for you.

If you use ng update, we’ll update your code automatically to use the new best practice.

Builder APIs in the CLI

In the same way that Schematics allow you to tap into ng new ng generate ng add and ng update, we’ve released new Builder APIs that allow you to tap into ng build ng test and ng run to perform processes like build and deployment.

Check out our blog post on these new APIs.

Or read the API documentation.

We’ve also been working with cloud providers to begin taking advantage of these APIs. Today you can try the latest version of AngularFire, which adds a deploy command, making build & deploy to Firebase easier than ever:

ng add @angular/fire
ng run my-app:deploy

Once installed, this deployment command will both build and deploy your application in the way recommended by AngularFire.

Workspace APIs in the CLI

Previously developers using Schematics had to manually open and modify their angular.json to make changes to the workspace configuration. With 8.0, we’re introducing a new API to make it easier to read and modify this file.

Read more about the available Workspace APIs.

Web Worker Support

Web workers are a great way to speed up your application if you do any sort of cpu-intensive processing. Web workers allow you to offload work to a background thread, such as image or video manipulation. We use web workers on angular.io for in-app search indexing.

You can now generate new web workers from the CLI. To add a worker to your project, you can run:

ng generate webWorker my-worker

Once you have a web worker, you can use it normally in your application, and the CLI will be able to bundle and code split it correctly:

const worker = new Worker(`./my-worker.worker`, { type: `module` });

Read more about web workers in the Angular CLI.

AngularJS Migration Improvements

If you use the $location service in an AngularJS application, Angular now provides a LocationUpgradeModule that enables a unified location service that shifts responsibilities from the AngularJS $location service to the Angular Location Service. This should improve the lives of applications using ngUpgrade who need routing in both the AngularJS and Angular part of their application.

Read more about the Unified Angular Location Service.

We’ve also documented best practices around lazy loading parts of your AngularJS application from Angular, making it easier to migrate the most commonly used features first, and only loading AngularJS for a subset of your application.

Read more about Lazy Loading AngularJS.

New Deprecation Guide

We are committed to maintaining Semantic Versioning and a high degree of stability even across major versions. For our public API, we are committed to supporting features for N+2 releases. This means that a feature that is deprecated in 8.1 will keep working in the following two major releases (9 and 10). For example, we are deprecating platform-webworker in version 8.

We are making it easier to find deprecations and removals in Angular. For a comprehensive list of all deprecations, see the new Deprecation Guide.

Ivy & Bazel

Ivy (new rendering engine) is one of the most exciting things in the Angular pipeline. These are opt-in previews and more updates will come soon.

In the current scenarios, e-commerce companies are very keen to create an online impact. The web and app development market are at its peak of popularity. There is a high demand for web and app developers with a growing number of websites. Angular has been a top choice for web development and it's the latest version AngularJS has gained popularity in the industry. This java script framework has created its prominent position in creating web apps.
Regardless of whether there are numerous different systems accessible for web development, AngularJS can support among them all. Since its introduction in the market, Angular has been creating waves in the market.

Introduction

Angular js is a powerful framework that was developed by Google. It is used to build dynamic apps with power-packed features. It was first introduced in 2010 and created by developers at Google. This framework was created to simplify and remove the challenges in creating dynamic apps. It uses HTML, CSS, and java script to create dynamic single-page applications. Angular Js is inclusive of Mongo DB and it is a frontend fragment of Mean Stack. In the developer's community, Angular is considered as a reliable and fast Java script framework. Many popular apps like PayPal. You tube, Netflix, the guardian, Lego are built using the AngularJS framework.

In this blog, we are listing some compelling reasons to pick angular development to familiarize you with its potential

• Open-source framework: It is not a library but open-source frameworks that enable the developers to build well-performing single page web applications. Just after its launch, it became hugely popular among the developers and it is not going to come at a halt.

• Simplified MVC structure: Developers use AngularJS to build robust and interactive web applications. AngularJS framework uses MVC architecture to create interactive applications. AngularJS makes it easy for developers to create apps as they are only required to split the applications.

• Extensive community: As angular is built by Google, it is backed by a very large community of professionals. The Angular JS conferences of the professionals are held all over the world. Hackathons are also organized in IT communities that include some professional and skilled engineers who can help with the queries and questions related to Angular.

• Declarative code system: In Angular JS developers can create declarative patterns by using declarative paradigms. It enables developers to be less heavy, and easy to read. In this framework, the developers get data models that are not too complex to write that abolishes the need to use any getter/setters and with easy data manipulation.

• Two-way data binding: It is one of the impeccable features that makes Angularjs popular in the developers' community. It allows seamless projections of the models and data binding. In this framework, any changes in the user interface make an impact on the application objects. The developers are not required to fresh the cycle and that makes it vulnerable to bugs.

• Using directives: AngularJS makes use of Directives as the developers can build custom HTML tags that function as custom widgets and it can be possible using directives. Its implications are also in the case of the use of decorating components and manipulation of DOM elements in appealing ways.

• Enterprise-level testing: When using Angular JS there is no need for demanding any other supplementary framework or additional plugins. In the process, parts of applications are put in the angular framework which is not too complex for manipulation. In module separation, developers can load essential services in an effective way for the performance of automatic testing.

• Client-side situation: AngularJS mainly works at the client-side and it is fully compatible with both web and mobile browsers. It can function with any projects without the need for any backend notifications. The developers can easily use AngularJS for the front end of applications.

• Easy to use: AngularJS is rich with its features and facilitates developers to reduce any need for writing codes. It reduces the burden of developers by the application of MVC architecture and data models.

Many other significant features make AngularJS prioritize by the developers than other Javascript frameworks. The above-mentioned reasons have made it the top choice for reputed companies all across the globe for web development. Developers at the company master the skills to work with Angular JS development for web.
