Reusable animations

A basic understanding of the following concepts:


The 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() 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 app components using the useAnimation() API.

In the above code snippet, transAnimation is made reusable by declaring it as an export variable.

Note: The height, opacity, backgroundColor, and time inputs are replaced during runtime.

You can import the reusable transAnimation variable in your component class and reuse it using the useAnimation() method as shown below.
