What is @angular/elements?

@angular/elements allows Angular components to be used as custom elements (web components). This enables the integration of Angular components into non-Angular applications and enhances reusability across different frameworks and libraries.

What are @angular/elements's main functionalities?

Creating a Custom Element

This code demonstrates how to create a custom element from an Angular component. The `createCustomElement` function is used to convert `MyComponent` into a custom element named 'my-element'.

import { Injector, NgModule } from '@angular/core';
import { createCustomElement } from '@angular/elements';
import { BrowserModule } from '@angular/platform-browser';
import { MyComponent } from './my-component.component';

@NgModule({
  declarations: [MyComponent],
  imports: [BrowserModule],
  entryComponents: [MyComponent]
})
export class AppModule {
  constructor(private injector: Injector) {
    const myElement = createCustomElement(MyComponent, { injector });
    customElements.define('my-element', myElement);
  }

  ngDoBootstrap() {}
}

Using the Custom Element in HTML

Once the Angular component is converted into a custom element, it can be used in any HTML file just like a standard HTML element. This example shows how to include and use the custom element 'my-element' in an HTML file.

<!DOCTYPE html>
<html>
<head>
  <title>Angular Element</title>
  <script src="path/to/your/angular-element.js"></script>
</head>
<body>
  <my-element></my-element>
</body>
</html>
