3. 100% Ivy and No Extra Assist for View Engine

Angular 13 doesn’t help the View Engine. The all-new model is now 100% Ivy. Now that there isn’t a View Engine-specific metadata or older output codecs, it eliminates the codebase complicacy and upkeep prices in Angular 13.

The framework has transformed all inner instruments to Ivy upfront in order that this alteration can operate seamlessly. Ivy assembles each element individually, which accelerates growth instances.

There isn’t a extra requirement of utilizing ngcc (Angular compatibility compiler) for the libraries created utilizing the most recent APF model. The event workforce can count on faster compilation as there isn’t a extra requirement for metadata and abstract information.

4. Ergonomic APIs

Angular v13 has diminished the load time utilizing ergonomic code-splitting APIs and granular code disruption at a element stage. The brand new launch of ESBuild has additionally introduced an enhancement of efficiency.

With the launch of Angular v13, this framework now helps persistent construct cache by default. It’s a function that caches construct outcomes on disk. It causes as much as 68% enhancement in growth pace. You’ll be able to allow or disable this function in present Angular apps.

6. Adjustments to the Angular Package deal Format(APF)

The Angular Package Format (APF) specifies the format and construction of the Angular Framework packages. It’s an amazing method to packaging each third-party library within the net growth ecosystem.

Angular 13 brings a brand new model of the APF, and we discover some important modifications in it:

• It creates Ivy partial compilation output.
• There isn’t a extra manufacturing of UMD bundles.
• It produces ES2020 output.

8. Element API Updates

Now, you may construct dynamic parts utilizing much less boilerplate code because of the improved ViewContainerRef.createComponent API. In case you use Angular 13, you don’t have to make use of ComponentFactoryResolver.

Right here’s an instance of making dynamic parts utilizing earlier variations of Angular:

@Directive({ … })
export class MyDirective {
    constructor(personal viewContainerRef: ViewContainerRef,
                personal componentFactoryResolver: 
                        ComponentFactoryResolver) {}
    createMyComponent() {
        const componentFactory = this.componentFactoryResolver.
                             resolveComponentFactory(MyComponent);
    
        this.viewContainerRef.createComponent(componentFactory);
    }
}

In Angular 13, this code can change into utilizing new API:

@Directive({ … })
export class MyDirective {
    constructor(personal viewContainerRef: ViewContainerRef) {}
    createMyComponent() {
        this.viewContainerRef.createComponent(MyComponent);
    }
}

9. No Longer Assist for Web Explorer 11

For having fun with the advantages of native net APIs and options of contemporary browsers like CSS variables and net animations, the Angular framework has lower off the help for IE11. It offers a faster load and smaller bundle measurement for purposes and an enhanced consumer expertise as there aren’t any IE-specific polyfills and no requirement for distinctive loading.

The brand new model of Angular has introduced an Accessibility (A11y) enhancement in Angular Materials. The workforce has assessed and checked all MDCs (Materials Design Parts) for improved accessibility. As an illustration, radio buttons and checkboxes now have bigger contact sizes, and different parts function larger distinction modes.

11. New Kind of Types

The discharge of Angular v13 highlights a brand new sort of type: FormControlStatus. It accumulates all standing strings for type controls:
