lottie

To render After Effects animations as lightweight JSON, use lottie-web with a container element and an animation source provided via a file path or animationData object. Optional rendererSettings and event hooks can be configured to control playback behavior.

Lightweight JSON animations are used for loading indicators, decorative UI motion, and interactive feedback in web and mobile apps. They replace heavy video assets to reduce app size and improve rendering performance.

Yes, you can use Lottie to replace heavy video assets in mobile apps. It renders vector-based After Effects animations as JSON data, significantly reducing app size while maintaining scalable UI motion.

Before displaying Lottie animations on the web, you need to install the lottie-web library and define a container element in your DOM. You then provide the animation source via a path or animationData object.

Lottie vector animations are generally better for UI motion than video assets because they are lightweight and scalable. Using JSON data instead of video files reduces app size and improves playback performance across web and mobile platforms.

You can configure event hooks and rendererSettings by passing them as optional parameters when initializing the Lottie animation. This allows you to control rendering behavior and respond to animation playback events.
