Top New Features of Angular 13

Noting all previous releases, Angular 13 is one of the most well-organized and well-planned changes for Angular's broadly used typescript-style web framework. Angular's creators have created and published eight various beta versions of Angular 13. I am sure you must be curious to know what new features are included in the latest Angular v13? So let’s take a look at the features and main highlights of Angular 13

Highlights of Angular 13

• To design components development of localization API
• Support of Reactive Extensions
• 70% growth in the build cache
• Disabling easier directives
• Advanced execution of APF

1. Ivy is completely Ivy.

The makers and providers of Angular services provider wished to improve the performance of dynamic components. API has been modified with this in mind. ViewContainerRef replaces ComponentFactoryResolver in the new API. createComponent without generating a corresponding factory

This is how the elements were made in the prior Angular version.

@Directive({ … })

export class MyDirective {

constructor(private viewContainerRef: ViewContainerRef,

private componentFactoryResolver:

ComponentFactoryResolver) {}

createMyComponent() {

const componentFactory = this.componentFactoryResolver.

resolveComponentFactory(MyComponent);

this.viewContainerRef.createComponent(componentFactory);

}

}

The new Api code will look like this

@Directive({ … })

export class MyDirective {

constructor(private viewContainerRef: ViewContainerRef) {}

createMyComponent() {

this.viewContainerRef.createComponent(MyComponent);

}

}

The Angular v13 update adds RXJS to all versions up to and including version 7. RxJS 7.4 will be the want for new apps built with the CLI. If you are using version 6, you will need to run the code manually: npm install [email protected] to enjoy the recent update.

2. No More Help for Internet Explorer

Angular 13 won’t support internet explorer. If you plan to hire Angular developers, you shouldn’t expect anything to create from IE11 as this latest version won’t support internet explorer.

3. APF changes

The latest version of APF has improved output formats as now it does not require ngcc usage so that developers can anticipate more agile performance and stronger package output.

4. TestBed Teardown Now Default

In v12, they added the TestBed configuration to make splitting down test modules and conditions more manageable. TestBed teardown is now allowed by default, but you can disable and configure it as needed.

5. Documentation Enhancements

$ localize is a well-maintained API used in templates and code to create a more effective approach for built-in internationalization and tag messages for translation!

6. Enhancements to Angular Material Accessibility

Approachability has been updated for MDC-based Angular Material components. Emma Twersky revealed how to increase the approachability of Angular Components.

7. TypeScript 4.4

1. Discriminant and situation control flow study
2. Index Signs for Template String Patterns
3. Default Catch Variables
4. Optional Property

Performance improvements of Angular v13

• The opt-in feature is now approved by default in the Angular CLI.
• The use of determined build-cache by default increases build speed by 68 percent for new v13 projects.
• Build performance has been updated to optimize packages and global scripts.
• The administration of incremental builds does not include any Angular traits

Changes in Angular v13

• All Angular packages include Node.js 16 in their node engines.
• ViewContainerRef.createComponent directly encourages component type.
• The current sign, which allows a ComponentFactory, has been opposed.
• With Ivy, the renderModuleFactory from @angular/platform-server is no longer required. RenderModule can be used instead.
• The Angular language supports autocompletion for union types in templates.

To conclude these were the new features of Angular 13 that was launched recently. The angular team is always curious to update their service and give the best customer experience. So if you are using old version then now it is time for you to use the new version with lots of new features and upgrades and enjoy the experience. If you want you can also take advantage of angular upgrade service providers for updating your project in the new version so that you can create exceptional applications.
