The [AnimationOptions](api/animations/AnimationOptions) interface in Angular animations enables you to create animations that you can reuse across different components.
|
|
|
|
## Creating reusable animations
|
|
|
|
To create a reusable animation, use the [`animation()`](api/animations/animation) method to define an animation in a separate `.ts` file and declare this animation definition as a `const` export variable. You can then import and reuse this animation in any of your application components using the [`useAnimation()`](api/animations/useAnimation) API.
|
|
|
|
<code-example path="animations/src/app/animations.ts" header="src/app/animations.ts" region="reusable" language="typescript"></code-example>
|
|
|
|
In the above code snippet, `transAnimation` is made reusable by declaring it as an export variable.
|
|
|
|
<div class="alert is-helpful">
|
|
|
|
**Note:** The `height`, `opacity`, `backgroundColor`, and `time` inputs are replaced during runtime.
|
|
</div>
|
|
|
|
You can import the reusable `transAnimation` variable in your component class and reuse it using the `useAnimation()` method as shown below.
|
|
|
|
<code-example path="animations/src/app/open-close.component.3.ts" header="src/app/open-close.component.ts" region="reusable" language="typescript"></code-example>
