Framer Motion

Adding expressive animations and smooth interactions to React applications is made easier with Framer Motion. It's described as A production-ready motion library for React, offering a declarative API for defining animations.

Framer Motion handles animating component mounting/unmounting, responding to user gestures like dragging or hovering, and even automatically animating changes in layout, enhancing the overall user experience with fluid motion.

Example: You could use Framer Motion to create an effect where clicking a button smoothly expands a hidden details panel using a spring animation.
