Regarding the latest release of Angular version 13, I will make sure to include everything noteworthy as we did in the previous blogposts of Angular 12, Angular 11, and Angular 10. If you are interested in a bird-eye view of what’s new in Angular 13, then here’s a quick sneak peek at Angular 13 release notes, quick Angular core updates and top new features of Angular 13.

Angular 13 Features

Here’s the latest Angular 13 new features that you should to before you upgrade your App to Angular 13.

(1) 100% Ivy

The creators and providers of Angular development services wanted to enable quality improvements in dynamic components. With that consideration, API has been simplified. The new API removes ComponentFactoryResolver with ViewContainerRef.createComponent without producing an associated factory.

Here’s how the components were created with the previous version of Angular.

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

Here’s how new API code can become.

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

(2) RxJS 7.4

Angular v13 update includes RXJS to all the versions upto version 7. New apps created with the CLI will default to RxJS 7.4. In case if you are using RxJS 6 in your existing app, you will have to manually run the command npm install [email protected] for the latest update.

(3) No More Support for Internet Explorer

Angular 13 won’t support internet explorer. If you are planning to hire Angular developer, then you shouldn’t expect anything to create from IE11.

(4) Changes to the Angular Package Format (APF)

Angular package format – APF has streamlined and modernized older output formats, including View Engine metadata. The updated version of APF does not require the usage of ngcc. As a result of these changes in the library developers can expect faster execution and leaner package output.

Angular v13 will ship with the most modern version of APF (Angular Package Format): ES Modules+ES2020

If you've ever maintained an npm library, you know how hard it is to come up with the right package format that is modern & works for most use-cases! ?https://t.co/A8HPqixfKk

(5) TestBed Teardown Now Default

TestBed configuration was added in v12 to conveniently teardown test modules and environment. TestBed teardown is the default feature now, but you can disable and configure it at your ease.

(6) Documentation Improvements

$localize is a stable API. $localize is used to create a more efficient method for built in internationalization (i18n) and tag messages for translation in templates and code! Check out these $localize docs to understand how to make learning and entry easier in Angular!

(7) Inline Support for Adobe Fonts

Just like Google fonts- V11, you can inline Adobe fonts as well. For your reference, I have attached Mark Thompson’s video screenshot to speed up the performance for font inline.

(8) Angular Material Accessibility Improvements

MDC based Angular Material components have accessibility improvements. Emma Twersky detailed more about improving Angular Component’s accessibility in this post.

(9) TypeScript 4.4

TypeScript 4.4 has the full support, and some of the big highlights of TS 4.4 include:

Control Flow Analysis of discriminants and conditions
Template String Pattern Index Signatures
Default Catch Variables (–useUnknownInCatchVariables)
Optional Property (–exactOptionalPropertyTypes)

Angular v13 Performance Improvements

The latest version of Angular 13 comes with several performance improvements:

Opt-in feature is now enabled by default
Improvements to the Angular CLI. There’s 68% performance improvements in build speed usage of persistent build cache by default for new v13 project
Improved build performance to optimize bundles and global scripts.
Incremental builds performance don’t contain any Angular traits like, Component, Directive, Pipe, Injectable, NgModule decorators.

Angular v13 Notable Changes;

Node.js 16 is added in all the node engines by all Angular packages.
The ViewContainerRef.createComponent supports component type directly. The present signature that accepts a ComponentFactory is now deprecated.
The renderModuleFactory from @angular/platform-server is no more required with Ivy. Instead, renderModule can be used.
The Angular language supports autocompletion for union types in templates.
