Angular Animations
Angular animations are a way to add motion and visual effects to your application. Animations in Angular are implemented using the @angular/animations
module, which provides a declarative API for defining animations and applying them to components.
To use animations in Angular, you will need to import the BrowserAnimationsModule
into your application module, and include the animations
metadata in your component's @Component
decorator.
Here's an example of how you can define an animation in Angular:
import { trigger, state, style, animate, transition } from '@angular/animations';
export const myAnimation = trigger('myAnimation',[ state('inactive',
style({ backgroundColor: '#eee',
transform: 'scale(1)' })),
state('active',
style({ backgroundColor: '#cfd8dc', transform: 'scale(1.1)' })),
transition('inactive => active', animate('100ms ease-in')),
transition('active => inactive', animate('100ms ease-out'))
]);
In this example, we are using the trigger
, state
, style
, animate
, and transition
functions to define an animation that changes the background color and scale of an element .
Certainly! Here's how you can use the animation in a component:
import { Component } from '@angular/core';
import { myAnimation } from './my-animation';
@Component({
selector: 'my-component',
templateUrl: './my.component.html',
styleUrls: ['./my.component.css'],
animations: [myAnimation]
})
export class MyComponent {
state = 'inactive';
toggleState() {
this.state = (this.state === 'inactive') ? 'active' : 'inactive';
}
}
In this example, we are using the animations
metadata to specify the myAnimation
animation that we defined earlier. We are also using a component property, state
, to control the state of the animation.
To apply the animation to an element in the component's template, you can use the @myAnimation
directive:
<div @myAnimation="state"> This element will animate when the state changes. </div>
You can also use the animation
binding to bind the state of the animation to a component property:
<div [@myAnimation]="state"> This element will animate when the state changes. </div>
