ATTENTION! To address many issues that have come up over the years, the API in v2 and above is not backwards compatible with the original React addon (v1-stable).

For a drop-in replacement for react-addons-transition-group and react-addons-css-transition-group, use the v1 release. Documentation and code for that release are available on the v1-stable branch.

We are no longer updating the v1 codebase, please upgrade to the latest version when possible

A set of components for managing component states (including mounting and unmounting) over time, specifically designed with animation in mind.

• Main documentation
• Migration guide from v1

TypeScript definitions are published via DefinitelyTyped and can be installed via the following command:

npm install @types/react-transition-group 

Clone the repo first:

git@github.com:reactjs/react-transition-group.git 

Then run npm install (or yarn), and finally npm run storybook to start a storybook instance that you can navigate to in your browser to see the examples.
