Motion is an open-source animation library for JavaScript, React, and Vue. It provides a simple API with first-class support for multiple platforms, a hybrid animation engine combining JavaScript with native browser APIs for 120fps GPU-accelerated animations, and production-ready features including TypeScript support, extensive test suite, tree-shakable builds, and a tiny footprint. Batteries included: gestures, springs, layout transitions, scroll-linked effects, and timelines.
The skill is based on Motion v12.29.2, generated at 2026-02-01.
