History of Angular’s versions

With the ever growing list of e-commerce websites coming online coupled with websites and web applications front end development has really evolved and the need for new and efficient technologies is ever expanding. Angular has been one of the most popular front-end JavaScript frameworks along with React and Vue.js that is being used by web developers across the globe.

The first version of the framework was launched in 2009 by the name of Angular JS. Then came in Angular 2 which was not just an update but completely new framework which was released with Typescript. Then on various versions of Angular have been released, the latest one being Angular 9 which was released in February, 2020. We are going to talk about the advantages of Angular 8 here which was released in May 2019.

Advantages of Angular 8

Differential Loading- In Angular 8 apps two separate bundles are created, one for the legacy JavaScript and the other for modern Javascript. To put it in an easier way, two bundles are created for the older and newer browsers. When the application is loaded on a web browser the correct bundle gets loaded by the browser. This improves the performance of the web application.

Ivy Renderer- As more and more people are using smartphones the need for web applications loading faster is also increasing. Ivy is a renderer that uses incremental DOM to build a rendering pipeline for Angular 8. This helps in making the bundles smaller and the tests and builds faster.

Lazy Loading- This is a design pattern to delay the loading or the initialization of an object until the time it is used. When an Angular application is compiled, the compiler creates a Javascript bundle. As an application grows this bundle size which is served at the user end also grows. This would result in the time taken to load the application and hence the performance of the application. In Angular 8 the support for dynamic import to the router configuration has been added to enable the use of import statements for lazy loading the desired module.

Bazel Support- When an application is being developed and there are a few changes in small part of the code then it does not make sense to rebuild the complete application. Bazel helps in incremental buils, that is, it triggers a build of the code that has changed. Bazel also reduces the concurrent build times after the initial build of an application. This is an opt-in option in Angular 8.

Google & Community Support- Google has Long Term Support (LTS) for Angular 8 which makes it clear that Google has long term plans to scaling and supporting the Angular eco system. There is a large community support for Angular and there are many resources available on the internet to support Angular from a developer’s perspective.

At Excelgens, our development teams have been using Angular in our web development projects for out .NET and PHP applications. We have developed projects right from Angular JS to Angular 8 and we acknowledge the Angular team for making the developer’s job easier with each release. Angular 8 is a very developer friendly solution and has the latest features built in to support web development requirements of the modern times.
