Rebound-js is a JavaScript library that models spring dynamics for driving physical animations in web interfaces. It provides a SpringSystem that iterates Spring objects through a physics solver until equilibrium, letting developers map position updates to UI property animations.

Use cases

• add springy bounce animations to web UI elements
• animate scale, translation, or rotation with physics-based motion
• create press-and-release interactive effects on buttons and logos
• drive interface animations from a lightweight physics simulation
• port Android-style spring animations to the web

When to choose

• you want natural, physics-based spring animations without a full animation framework
• you need a small, dependency-free library for bouncy UI interactions
• you want consistent spring behavior matching Facebook's Android Rebound library

When to avoid

• you need a full-featured animation library with timelines, keyframes, and easing
• you require actively maintained software with ongoing support
• you need GPU-accelerated or CSS-only animation solutions
