Latest features in angular 13

We are familiar with the fact that angular is taking on a vital role in application development. We can acquire remarkable features by using this updated version of angular. We can also update your current version of angular to get multiple features. It can be done by following simple tips. This version is crowded with Ivy-based features to improve our experience. Updated APF is another reason for users’ satisfaction and attraction. Now we are going to discuss the latest features of angular v13.

  1. Ivy-based features: It is regarded as one of the most important features of Angular v13. Support for the view engine has been removed to incorporate the facilitation of the Ivy engine. This advancement is enough to make the ways for introducing improvement in features of Angular v13. It plays a key in delivering the best tools and techniques for developers to attain perfect results regarding their projects. Omitting the view engines helps to decrease the dependency of Angular on ngcc. It results in a quick compilation by excluding summary files and metadata.
  2. Alterations to APF (Angular Package Format): It is another thing to be considered about the latest version of Angular. The previous format of output has been omitted to update the APF in v13. Latest JS formats are also involved to modernise APF. There is no need for ngcc for the libraries that are developed with the updated version of the angular package format. It helps to complete the execution in less time and it is quite a fascinating factor for developers. This advanced APF also supports Node Package Exports.
  3. Improved Command Line Interface CLI: Angular permits the usage of persistent build-cache by default for the projects using v13. This update helps to improve the build speed by 68%. ESBuilt helps in improving the performance by working with terser for the optimization of the global script. It is also a reason for global CSS optimization and all style sheets. It also supports CSS source maps.
  4. Updates in component API: Ivy also assists developers to create the components dynamically.  This process of creating the components requires boilerplate code. 
    1. The latest API has omitted the need for ComponentFactoryResolver. Ivy helps to detect the component with the help of ViewContainerRef.createComponent. There is no need to create an associated factory in this concern.
    2. From @angular/platform-server the renderModuleFactory is no longer necessary with Ivy and renderModule should be prefered in the app instead.

Applications that are created with ng new contain RxJS 7.4 by default. But the existing apps must be updated manually for relishing the latest features. The latest version also supports TypeScript 4.4.
  1. Improved Angular tests: The Angular v13 also made some useful changes in TestBed for performing the job to disintegrate the test modules after completion of each test. Quicker, lesser memory intensive and extremely optimised tests can be performed due to the changes introduced by Angular in version 13. It can be done by cleaning the DOM after every test. The Angular testing module option destroyAfterEach default value is set to true as of Angular 13. This option was introduced in Angular 12.1 and previously it was defaulted to true.
