What’s New in Angular?
For example, Angular 8 has enabled several new launch partners like Angular Console for operating Angular projects, Angular Fire for amalgamating Firebase with Angular, and NativeScript and StackBlitz for developing native mobile apps.
The list of new features and amazing benefits of Angular 8 JS frameworks is never-ending. So, let’s go over and summarize the significant new features and advantages of Angular 8 in conjunction with learning the right way of upgrading Angular seven web apps to Angular 8.
If you have been following Angular frameworks, then you would’ve probably encountered the term ‘Ivy.’ Angular Ivy is a notable change in the history of Angular frameworks. It refers to a different angular renderer that uses incremental DOM.
● Improved build times through an incremental approach
● Enhanced backward compatibility
● Lazy loading of components instead of modules.
● Better and more compatible payload sizes
How Angular 8’s Ivy Works on Incremental DOM?
The main plan behind Incremental DOM is to compile every pre-built element and ready-to-use component into a series of instructions, and these instructions eventually create DOM trees. The template functions are the rendering engines, and hence, they contain all the necessary instructions that are required for rendering as well as updating DOM trees in case of data change.
You need to know that Angular Ivy works on two main concepts:
A) Low Memory Footprint – Incremental DOM doesn’t require any memory to re-render the view, and therefore, it allocates the memory in case of the addition or removal of DOM nodes. Since most of the template or render calls don’t change, it eventually results in huge memory savings.
B) Tree Shakable – It refers to the removal of unused code scraps to allow web apps to focus on codes that are being used. This exclusion of unused instructions eventually results in smaller bundles and faster run time.
WrapPixel preferably uses Angular Ivy in place of the Angular View Engine, as it offers the following benefits to the users.
● Angular Ivy offers a reduced payload size to allow browsers to take less time to parse or download your web apps.
● The code sections that are generated by the Angular compiler are much easier for web developers to read and understand.
● Angular Ivy significantly lessens the rebuild times.
● It provides better Angular 8 template type checking to enable users and developers to catch more errors at build times as well as prevent them at app runtime.
Angular Ivy intends to be largely compatible with the existing Angular web apps, which means that you can get all of Angular Ivy’s advantages without having to change your web apps.
The correct bundle is loaded automatically by the browser and is further used for downloading smaller and more efficient web app bundles with quick loading and fast rendering.
● Creates web-optimized bundles for modern browsers.
● Allows browsers to load the right set of bundles.
● Creates legacy bundles for older web browsers.
● Automates the browser loading process by aiding a CLI extension.
Enhanced Web Worker Bundling
Angular 8 incorporates web workers that are exceedingly essential for enhancing performance and parallelizability while building the production bundles. It means that Angular 8 is adding dynamic building support to CLI, thereby providing one bundle for every web worker.
Angular Router Backwards Compatibility
The possibility of Angular frameworks to build CLI web applications using Bazel is simply outstanding. You need to know that the angular framework embraces the Bazel Support for web developers.
Bazel Support is also included in version 9 of Angular CLI and is readily available as an opt-in. The prime benefits of the Bazel Support feature of the Angular 8 framework are as follows:
● Bazel offers faster build time by aiming for reproducible builds. It also allows the Angular web app to use several libraries and modules during its development.
● Bazel provides incremental build by triggering the smallest build to eventually deploy the changes within the entire web app.
● Enhances the possibility to have remote builds on the build farm.
It is an incredible feature of Angular 8, and it is based on the concepts of angular routing. Lazy loading helps to bring down the large file sizes by lazily loading the required files.
WrapPixel is aware of the fact that in the previous angular versions, the framework’s route configuration uses @loadChildren to accept a string excusing any wrong module name or code typos.
However, Angular 8 includes added support with dynamic imports for router configuration. This use of import statements for lazy module loading eventually allows it to be understood by web packs and IDEs.
Opt-in Usage Sharing
Angular CLI has gained another new feature for aligning with the community needs ad it is opt-in usage sharing. This incredible feature of the Angular 8 framework enables opt-in sharing of Angular CLI usage with the Angular team along with allowing Angular 8 to collect essential data and user commands.
The all-new Angular 8 allows the developers to use Builders API. Developers can use these Builders APIs for performing several main operations like building, testing, linting, serving, and e2e. The builder’s API are functions that can easily implement the behavior and logic for different web app development tasks by replacing commands. You can easily create custom builders with the help of Angular 8 frameworks.
CLI Workflow Enhancements
API Migration Improvements
The angular team provides support for web developers by upgrading AngularJS frameworks as well as integrating them with AngularJS location service in hybrid apps. A new package is also integrated within Angular 8 to help web developers:
● Track all location changes.
● Retrieve the Angular state from location services.
● Test the location service using Mock Platform Location API.
● Retrieve hostname protocol search properties available in AngularJS.
It is also important for you to know that Angular 8 officially provides added firebase support to enable web developers to employ their web applications using Angular CLI.
The Amazing Benefits of Angular 8
Although WrapPixel has been making efficient use of the previous versions of Angular, it is unquestioned that in the making of the fresh new Angular HTML templates, the latest features of Angular 8 have proved to be very significant. With Angular 8, you can easily enjoy the web applications of Ivy along with differential loading and exceptional performance gains. Other benefits of Angular 8 include:
● High Performance
● Unit-Test Friendly
● Component-based architecture
● Higher-Quality Coding
● Updated Typescript with cleaner code, better tooling, and higher scalability
● Angular universal
● Multiple Angular elements
● RxJS for asynchronous and efficient programming
● Angular universal
● Ivy renderer
● Platform-agnostic philosophy
● Google’s long-term support
● Seamless updates with Angular CLI
● Angular Material Design Interface Engineering
How to Update from Angular 7 to Angular 8?
● It is imperative for you to use the 12th version of Node.js to update your Angular framework to Angular 8. To check your current version of the node, you can run the $ node v-command.
● It is possible for different syntax errors to occur because of the presence of typescript version 3.4. It might cause some issues to upgrade to Angular 8.
● While upgrading from Angular 7 to Angular 8, it is imperative for you to update the Angular Material in the application with the help of the $ ng-update command.
Final Thoughts on Angular
Summing up all the above-listed features and benefits, Google’s Angular team has done a great job by developing an incredibly dynamic and interactive framework. Angular 8 is a much more accessible solution that aims at certain essential modern technological trends.
With every new release and unified Angular location services, this framework has ultimately made the platform much better and simpler than it ever was. It is a boon to WrapPixel and its users.
