Popmotion is a low-level JavaScript animation library providing composable keyframes, spring, and decay animations for numbers, colors, and complex strings. It is framework-agnostic, tiny (~4.5kb for animate), written in TypeScript, and portable to any JavaScript environment.

Use cases

• animate numbers, colors, and css strings in the browser
• create spring physics animations for ui elements
• animate svg path definitions and box shadows
• build custom animation systems on a composable low-level toolbox
• add keyframe and repeat/delay animations to javascript apps
• integrate motion into any framework without a heavy dependency

When to choose

• you need a tiny, framework-agnostic animation engine
• you want spring physics or keyframe animation of arbitrary values and strings
• you are building your own higher-level animation or gesture library
• you need individually importable functions to keep bundle size small

When to avoid

• you want a batteries-included declarative animation framework with components
• you need React-specific animation APIs out of the box (consider Framer Motion, by the same author)
• you require css transition orchestration or scroll-linked animations as built-in features
• you need a project with an explicit license file or very active recent development
