Key Features Of Angular V13

Angular is a structural framework for developing dynamic web apps. It allows developers to use HTML as a template language and allows HTML’s syntax to express the application’s components briefly and clearly.

It is a fully featured JavaScript framework that helps developing dynamic, single page web apps. It also supports the (MVC) programming structure.

Angular 13 features
Changes to APF 

The Angular Package Format (APF) defines the format and structure of Angular Framework packages and View Engine metadata.

The Angular Package Format (APF) improvements are below. 

Older output formats, including some View Engine-specific metadata, are removed
The output size is small and faster execution
Libraries built with the latest version of the APF will no longer require the use of ngcc.
IE 11 support removed

Angular will no longer support Internet Explorer 11 as of version 13. Dropping IE 11 is a positive factor because it results in smaller bundle size and faster app loading.

In addition, Angular can now use modern browser features like CSS variables and web animations via native web APIs due to these enhancements.

IE-specific pollyfills helps to provide support to load applications on old browsers. It helps to provide differential loading. 

Improved APIs and infrastructure will be an advantage for developers, while application users will benefit from faster loading and a better user experience.

During project migration, running ng update will automatically remove these IE-specific polyfills and reduce the bundle size.

TypeScript 4.4 Support

TypeScript 4.4 support is now available in Angular 13 version. As a result, versions prior to TypeScript 4.2 and 4.3 are no longer supported.

Highlights of TypeScript 4.4 are:

Improved detection of type guards.
Default catch variables.
Faster incremental builds.
The control flow of conditions can be analyzed.
Symbol and template string pattern index signatures.
Form Validation Improvements 

In angular13 one of the new features, Form Control Status, was introduced and it is used to apply to better check on form controls. Previously we could find the valid and invalid status. Now we can also find  ‘Enabled’, ‘Disabled’ and ‘Pending’. 


It is showing form control status is enabled when control is including any values in the controls. 


It is showing form control status is disabled when control is excluded from any computations or calculations of validity. 


It is showing form control status is pending when async validation is happening and errors do not yet exist for typed value. 

Improvements to Angular Testing  

The Angular team has made some notable changes to TestBed, which now correctly tears down test environments and modules after each test.

The DOM is now cleaned after every test and developers can expect faster, less memory-intensive, less interdependent, and more optimized tests. 

beforeEach(() => {


   TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting(), {

       teardown: {

           destroyAfterEach: true




Removal of View Engine

The legacy View Engine has been completely removed to reduce the complexity of the Angular 13 codebase.

Angular 13 has completely shifted to Ivy which makes it easier for developers to improvise the dynamic components easily.

Ivy can reduce its reliance on ngcc. And Faster compilation because metadata and summary files are no longer included.

Router Improvements

Routing help us to handle navigation from one view to the another. It enables easy navigation by interpreting a browser URL as an instruction to change the view.

With the latest update, the router no longer replaces the browser URL when new navigation cancels the current navigation.

A new option called canceledNavigationResolution is added to the router. It helps the router to restore the state when navigation is canceled. The routerLinkActive now has a new output isActiveChange. It is an event emitter and returns a Boolean value. Return true when the link is hit or gets active and return false when the link becomes inactive.

Angular CLI enhancements 

Angular CLI stands out to be one of the most crucial aspects of the overall angular architecture. Angular CLI helps standardize the process of handling the complexities of the modern web development ecosystem by minimizing these complexities on a large scale.

With the release of Angular 13, significant changes to the Angular CLI are introduced for performance improvement.

Built-in support of persistent build cache
Easy enabling and disabling options for the build cache by the angular.json file
Up to 68% increase in speed of build-cache leading to faster deployment activities.
Framework Modifications and Dependency Updates

The Angular 13 update adds RxJS, a reactive extension for JavaScript, and includes all versions of RxJS up to and including version 7.

For apps created with ng newRxJS 7.4 has become the default.

Existing RxJS v6.x apps will need to be manually updated with the npm install rxjs@7.4 command. You can always rely on RxJS 7 for new project creation. As for migrations, existing projects should keep on RxJS 6.

Inline Support for Adobe Fonts 

In angular 13 inline fonts can improve your app performance by speeding up the First Contentful Paint. 

Now we can get access to everybody by default. But we need to give ng update command. 

Improvements in Localization 

Localize is a consistent API. Developers use it to produce an effective way for in-built internationalization (i18n) and tag messages for translation in code and templates. 

Angular 13 update 

If you need to update the old versions of the currently working project you can easily update to angular 13. Enter the command ng update to update the angular project to the latest version.

ng update @angular/cli @angular/core

If you update the angular 13 main focus time things will be less complex and there will be improved application performance as well.
