A small React component library (Transition, CSSTransition, SwitchTransition, TransitionGroup) that manages component mounting/unmounting states over time to make enter/exit animations easy. It exposes transition stages and manages classes rather than animating styles itself.
Use cases
- animate react components entering and leaving the dom
- add css transitions on mount and unmount in react
- fade in and out lists when items are added or removed
- manage transition lifecycle stages for react components
- replace react-addons-css-transition-group in modern react
When to choose
- you use React and want declarative enter/exit transitions with CSS classes
- you need fine control over transition stages without a full animation engine
- you want a tiny dependency for mount/unmount animation state
When to avoid
- you want a library that animates styles for you, like react-spring or framer-motion
- you are not using React
- you need complex physics-based or gesture-driven animations
