TL;DR

A React library that animates values using spring physics instead of fixed timing, so UI motion feels natural and responsive.

Why would anyone build with this?

REASON 1

Animate a sidebar sliding open with natural, bouncy motion instead of rigid timed transitions.

REASON 2

Make a notification pop in and settle smoothly using spring stiffness and damping values.

REASON 3

Animate a list rearranging itself in real time as underlying data changes.

REASON 4

Build a carousel or menu that adjusts mid-animation if new data arrives, without glitching or restarting.

Spring-based timing means you can't predict exactly when an animation finishes, so avoid it for millisecond-synced effects.

Show me how to use react-motion to animate a sidebar sliding open with a spring instead of a fixed-duration transition.
Prompt 2
Explain how to tune react-motion's stiffness and damping values to make a notification feel bouncy versus smooth.
Prompt 3
Using react-motion, animate a list of items reordering themselves when the underlying data changes.
Prompt 4
What's the tradeoff of react-motion's physics-based animation versus time-based animation, and when should I avoid it?
