airbnb/lottie-web

This system is a JavaScript-based animation player, specifically lottie-web, designed to render vector-based animations exported from Adobe After Effects. It provides a modular architecture that supports multiple rendering backends, including SVG, Canvas, and HTML/DOM, allowing for flexible and performant animation playback. The system handles complex animation features such as 3D transforms, audio synchronization, visual effects, and expression-driven properties, while also offering headless rendering capabilities via web workers.

The project underwent a comprehensive architectural overhaul, refactoring the animation player into modular, class-based components for SVG, Canvas, and HTML rendering. This period also introduced web worker support for headless processing and expanded the expression engine to support complex 3D transforms and audio integration.

17 changes

This period focused on a comprehensive refactoring of the player's internal architecture, introducing a modular system for rendering, object pooling, and text animation. The changes significantly expanded support for advanced vector effects, SVG-based visual filters, and dynamic shape manipulation, while improving performance through memory management and structural improvements.

8 changes

The project focused on restructuring the codebase into a modular architecture, allowing users to import only specific renderers and effects. This period also introduced automated build scripts to streamline library distribution and added centralized audio and marker parsing utilities to enhance player functionality.
