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.
npm install react-transition-group --save
yarn add react-transition-group
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, link to the following CDN: https://unpkg.com/react-transition-group/dist/react-transition-group.js
