React Transition Group

Exposes simple components useful for defining entering and exiting transitions. React Transition Group is not an animation library like React-Motion, it does not animate styles by itself. Instead it exposes transition stages, manages classes and group elements and manipulates the DOM in useful ways, making the implementation of actual visual transitions much easier. Since react-transition-group is fairly small, the overhead of including the library in your application is negligible. However, in situations where it may be useful to benefit from an external CDN when bundling. A set of components for managing component states (including mounting and unmounting) over time, specifically designed with animation in mind. The Transition component lets you describe a transition from one component state to another over time with a simple declarative API. Most commonly it's used to animate the mounting and unmounting of a component.
