Animations play a crucial role in an application’s user experience (UX). A set of well-designed animations can make an application feel fast, polished, and professional. However, creating animations can be a daunting task that involves knowing what is available and how to choose the right approach for each task.

You will start with the easiest methods and move on to more advanced animation methods as you make your way through this course. You’ll start with general animation techniques, covering CSS transitions, animations, and the Web Animations API, followed by Angular animations and integrating external animation libraries. Lastly, you’ll finish with a deep dive into animation performance and debugging.

This course will provide you with information and advice to help you create beautiful and performant animations in Angular applications. By the end of the course, you will be able to create performant animations and choose the right tools to create them effectively.

Animations in Angular

# Start and done events

Angular animations emit two events that we can listen to. They emit a `start` event as the animation starts and a `done` event when the animation completes.


We can listen to the `start` and `done` events by attaching a callback to our element with the animation trigger.

Let’s take a look at an example of an element that has a `slideUp` animation trigger attached to it (**line 2**). We’ll then use the trigger name followed by the word “start” to listen to the `start` event (**line 3**). Similarly, the `done` event uses the trigger name followed by the word “done” (**line 4**).


Angular calls the `animationStarted` and `animationCompleted` functions as the animation starts and completes with information about the animation.


Learn how to listen to events emitted by Angular animations and what properties are returned in these events.
