May 13, 2022
Angular is a robust and open-source framework that allows web developers to create more appealing websites. With advancements in its architecture, a well-off Angularjs development agency can now make your site more appealing with greater ease than ever before.
Since its inception in 2010, the Angular developer community is constantly involved in improving the framework by providing the latest upgrades and enhancements in the angular framework.
After Angular 12, Angular released v13 on November 4, 2021, which is now openly available as an active version till May 04, 2022. Significant changes and features are observed in this latest version, making the development process more efficient.
With recent advancements in typescript, NodeJs & Angular CLI versions; the removal of Internet Explorer 11 to improve browser compatibility for users is one major update that sets it apart from its older counterpart.
The releases of Angular have been eagerly awaited by many web developers as it is one the most streamlined and previously planned upgrades for a widely accepted TypeScript-based framework.

Type Script 4.4 Support Enabled
The new version: Angular 13 supports Typescript 4.4, which means we can now use many fantastic language features that were previously not available to us due to a backward-incompatible change in earlier releases such as setters and getters being removed from the type system. Though Node.js versions older than V12.20 are no longer supported due to Angular packages, one beneficial effect of using this update however is that it won’t disrupt your app when running on older versions like Type Script 4.2 and 4.3 or even before.
100% Ivy and No More Support for View Engine specific metadata
Angular 13 no longer supports the View Engine, but all-new versions are now 100% Ivy. This means that there are less codebase complicacy and maintenance costs because older output formats will not work with this new update removing any compatibility issues caused by previous changes made in the Framework version 4. The framework has converted all internal tools to Ivy in advance so that this change can function seamlessly. Ivy assembles every component individually, which accelerates development times.
Angular CLI Enhancements
The Angular CLI is an essential tool for modern web developers. It makes the workflow easier and smoother by doing most of what you need to do in one place, saving time on multiple steps throughout your development process which is otherwise tedious or requires expertise that not everyone has access to. Angular CLI basically does everything you need it to and helps take care of all those pesky little problems that often come up in web apps.
With the new version 13, angular developers can now enable a persistent build-cache by default. This feature will cause up to 68% enhancement in development speed for existing apps and is an added benefit that caches build on disk which speeds things right along.
Ergonomic APIs
The release of Angular v13 has reduced the load time using ergonomic code-splitting APIs and granular disruption at a component level. ESBuild also brings an enhancement in performance with this new update.
The ESBuild JS Bundle is a highly-efficient way to pack your website with minimal coding. Now, it works in tandem with Terser for optimized global scripts that work across all frameworks including Vue, Elm, or Svelte depending on what you need.
Enhancements to Angular Tests
The Angular team has made a few changes to TestBed that currently functions properly in order for the test environment and modules to be torn down after every single one of your tests. With DOM cleaning now possible, expecting developers will have more optimized less interdependent applications with lower memory requirements as well quicker runs on their battery life.
Improvements in Angular Package Format (APF)
The Angular Package Format is an industry-standard package format for storing libraries used in web app development. It provides great guidelines and structures every third-party library into its own unique repository, which makes it easy to find what you need when working on projects with multiple developers or yourself.
Angular 13 brings a new version of the APF, and we find some significant changes in it:
- There is no more production of UMD bundles.
- It produces ES2020 output.
- It creates Ivy partial compilation output.
- The node command-line tool exports all of its available outputs to files with a subpath pattern, making them easy for developers to use multiple versions or paths in their projects.
Component API Updates
The ViewContainerRef now offers an improved API to create dynamic components with less boilerplate code. If you use Angular 13, there is no need for ComponentFactoryResolver anymore.
Here’s an example of creating dynamic components using the previous versions of Angular:-
In Angular 13, this code will appear when the new API is used:-
No more support for Internet Explorer 11
The Angular framework has discontinued support for Internet Explorer 11, which means you can no longer utilize the APIs and features of modern browsers like CSS variables and web animations in this browser. There are no IE-specific polyfills or need for separate loading, resulting in a quicker load and smaller bundle size for apps.
Some organizations or authorities that are still using IE 11 and haven’t yet migrated to Microsoft Edge or other modern browsers will notice a significant difference.
Improvements in Localization
$localize is an efficient API that offers developers the perfect way to produce for internationalization (i18n) and tag messages in code or templates.
Changes in Framework and Dependency Updates
The latest version of Angular 13 also comes with some crucial changes and updates. Now, RxJS v7 is the default for new applications built using the ng module; however current users must update manually by installing rxjs@7 during their build process if they want access to its features such as observables or reactive requests (which replaces Subject).
Accessibility Update in Angular Material
With the new version of Angular, Google has introduced an accessibility enhancement in their Material Design Components. They have assessed and checked all MDCs for improved A11y features like larger touch sizes on radio buttons or checkboxes that feature higher contrast modes to make them easier to use when someone has a cognitive disability.
New and Improvised Forms
The introduction of Angular v13 introduces a new kind of form: FormControlStatus. It gathers all status messages for form controls:
For example, the AbstractControl.status is now FormControlStatus instead of a string.
The type of StatusChanges is now Observable<FormControlStatus> in place of Observable<any>.
Inline Support for Adobe fonts
The introduction of Angular 13 has introduced an exciting change that allows users to use Adobe fonts by default. These enhanced apps are able to make FCP (First Contentful Paint), which is significant for optimizing app performance and user experience!
This new update means you don’t need any extra modules or libraries anymore- just ng update will do it all.
Wondering how to Upgrade to Angular 13?
