Usage noteslink

To use this service, add it to your component or directive as a dependency. The service is instantiated along with your component.

Apps do not typically need to create their own animation players, but if you do need to, follow these steps:

1. Use the build() method to create a programmatic animation using the animate() function. The method returns an AnimationFactory instance.

2. Use the factory object to create an AnimationPlayer and attach it to a DOM element.

3. Use the player object to control the animation programmatically.

For example:

      
        content_copy
      
      
// import the service from BrowserAnimationsModule
import {AnimationBuilder} from '@angular/animations';
// require the service as a dependency
class MyCmp {
  constructor(private _builder: AnimationBuilder) {}
 
  makeAnimation(element: any) {
    // first define a reusable animation
    const myAnimation = this._builder.build([
      style({ width: 0 }),
      animate(1000, style({ width: '100px' }))
    ]);
 
    // use the returned factory object to create a player
    const player = myAnimation.create(element);
 
    player.play();
  }
}
