And if you need to get the newest version, just head over to the official download page for Node. With that command, your lazy loaded route imports will be migrated to the new import syntax automatically. We’ll have to wait a little bit more for Ivy, the new rendering engine, and Bazel, the new build system, to be ready for official use with Angular. The change in syntax will be taken care of for you if you’re using the ng upgrade command to upgrade your app.

There should be plenty of new features here to help you build better apps today and give you reason to be excited about the future of Angular.

How To Choose The Right Tech Stack For Web Development

The proper bundle will be loaded automatically by the browser itself. Angular 8 comes with a new rendering version called Ivy, which uses incremental DOM. It comes with many features like producing smaller bundle sizes, faster compile time, and easy debugging. There are strong reasons why Google didn’t go with the Virtual DOM in Angular 8. Incremental DOM helps the application to perform excellently on mobiles by optimizing the bundle size as well as memory footprint. Now, it added assistance for dynamic imports while configuring the routes.

Before Angular 9, there was a get function TestBed.get() that congested taking string values after Angular 8. To solve the issue, they came up with a solution known as TestBed.inject() and criticized the get function. But now the TestBed API has been enhanced and made inject function work the same as get function.

CLI Builder API is secure and obtainable to developers who want to tailor the Angular CLI by accumulation or amending the commands.

To keep their efforts in alignment with the community’s needs Angular CLI will be gaining another new feature i,e opt-in usage sharing. Obviously, some newer browsers will have smaller bundles to load (even up to 20%).

This will help the Angular team to make better Angular development tools. Command Line Interface will now produce separate bundles for modern JavaScript Apache Avro Java 1 7 6 API (ES2015+) and legacy JavaScript . Advanced modern browsers with ES2015+ support will be able to download more productive app bundles.

With view-engine enhancements and code generation reductions in Angular 4, applications consumed less memory and they run quicker than their previous versions. Angular Universal was introduced as the core Angular Module which makes it easy to import the functions from the library. Angular is one of the most popular front-end JavaScript framework comparing React & Vue.js for web app development. Its first version was released in 2009 and It has been around for the past 10 years, and since then, it brought an impressive list of changes and improvements.

  • Ivy is a new compiler/runtime of Angular and Angular 8 is a first release to offer a switch to opt-in into Ivy officially.
  • Differential Loading is an Angular 8 feature that will make web apps load faster and perform better.
  • Angular 8 comes with the support of TypeScript 3.1 which is a pretty major update over the previous iterations of the framework.
  • Though this doesn’t bring changes in Sass files, the compiling process might become a little complex.

It allows developers to utilize import statements that facilitate the lazy loading of modules.

It hampered the process of automatic bundling of Javascript into as few files as possible. It was launched in May 2019, seven months after its previous version, i.e., Angular 7.

Angular is the trending web technology and it helps web developers in creating better front end development. Angular has updated a number of versions and the latest one is Angular 9.

Alex Eagle said that Bazel is a build tool for XL apps, Angular apps, and apps which have above 2500 components. It’s because the time of building may be too long – that’s annoying and nobody likes it. Bazel will improve building speed with incremental builds and deploys.

The extensions consist of Angular snippets, ESLint, as well as the debugging extensions. Along with these, the stability and performance level problems have even been fixed-up. Moreover, the update has lesser breaking changes which allow your existing applications to work smoothly without any alterations.
