What is Angular JS?
The angular version was focused mainly on the toolchain and other steps to migrate it quicker instead of concentrating on the underlying framework. Depending upon the versions of Angular JS different applications were made with distinctive features. Angular 7 is the latest released version and many people are so enthusiastic to know about the new update features and improvements made. . Simply by using Angular, developers can be able to build live applications on the web, and multiple app designs on mobile applications.
Angular 7 highlights
This Angular 7 upgrade is certainly useful one to the Angular front-end developers which includes improvements to the Angular material and other core frameworks, and CLI with major versions. Angular version 7 is mainly focused on Ivy project and can fulfill the requirements which are not met in the past version. Ivy project is rewriting the angular compiler and code to make it even more efficient and faster.
Following are the some of the extensive features that are packed with the new Angular version,
CLI prompt option is updated to v7.0.2 with various distinctive features. Now it enables the users to get prompts while typing some commands such as @angular/material, ng-add, ng-new etc. These prompts help the users to know about the in-built SCSS support and more options. And the new facility is it’s totally customizable. The user can add schematic.json by using schematic CLI, and can command the Angular CLI prompts to execute.
Google is aiming in improving the performance of the applications, and in that analysis process, they found out the errors made that the developers added reflect-metadata polyfill production. To solve this error and also for the update, Google finally decided to take out the polyfills.ts files automatically, rather than creating an application in the JIT mode. Now the polyfill can be removed in the production phase itself. The user can change the defaults in the angular.json file. Developers’ job is to set the warning and error size.
The Angular Material CDK
At present, a lot of mobile frameworks are inclined to create dynamic loading data pages like images or long lists. To follow that suit, Angular included ScrollingModule to enable the virtual scrolling option. Various elements can get or lose visibility and they can be virtually loaded from the DOM. By using this scrolling option, better performance can be obtained for the user. Angular 7 sticks with cdk-virtual-scroll viewport component to boost the performance.
Drag Drop Module
By using Angular material drag and drop module can be incorporated so that users are able to reorder lists and to transfer different items among the lists. CDK can handle automatic rendering, drop handlers, drag handlers and they can move the data.
Angular Compatibility Compiler (ngcc)
This compiler is used to convert the node modules which are compiled with the ngc to other node modules that are compatible with new Ivy renderer. Angular compatibility compiler transforms node modules that are compiled with ngc to node modules that have to be compiled with ngtsc. This kind of conversion allows the legacy packages in the Ivy rendering engine.
Accessibility of Selects and other elements
Angular 7 came up with the improved accessibility of selects in the application. The native select element is used in the mat form field. Because of this change, easy accessibility, improved performance, and usability can be achieved. Angular elements assist in projecting the content by using certain standards for the custom elements.
