> **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)`](https://github.com/reactjs/react-transition-group/tree/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`](https://github.com/reactjs/react-transition-group/tree/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.

## Documentation

- [**Main documentation**](https://reactcommunity.org/react-transition-group/)
- [Migration guide from v1](/Migration.md)

## TypeScript
TypeScript definitions are published via [**DefinitelyTyped**](https://github.com/DefinitelyTyped/DefinitelyTyped) and can be installed via the following command:

```
npm install @types/react-transition-group
```

## Examples

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.

     *   var Props = require('ReactPropTypes');
     *   var MyArticle = React.createClass({
     *     propTypes: {
     *       // An optional string prop named "description".
     *       description: Props.string,
     *
     *       // A required enum prop named "category".

     *
     *   type := array|bool|func|object|number|string|oneOf([...])|instanceOf(...)
     *   decl := ReactPropTypes.{type}(.isRequired)?

     * The animation classNames applied to the component as it appears, enters,
     * exits or has finished the transition. A single name can be provided, which
     * will be suffixed for each stage, e.g. `classNames="fade"` applies:
     *
     * - `fade-appear`, `fade-appear-active`, `fade-appear-done`
     * - `fade-enter`, `fade-enter-active`, `fade-enter-done`
     * - `fade-exit`, `fade-exit-active`, `fade-exit-done`
     *
     * A few details to note about how these classes are applied:
     *
     * 1. They are _joined_ with the ones that are already defined on the child
     *    component, so if you want to add some base styles, you can use
     *    `className` without worrying that it will be overridden.
     *
     * 2. If the transition component mounts with `in={false}`, no classes are
     *    applied yet. You might be expecting `*-exit-done`, but if you think
     *    about it, a component cannot finish exiting if it hasn't entered yet.
     *
     * 2. `fade-appear-done` and `fade-enter-done` will _both_ be applied. This
     *    allows you to define different behavior for when appearing is done and
     *    when regular entering is done, using selectors like
     *    `.fade-enter-done:not(.fade-appear-done)`. For example, you could apply
     *    an epic entrance animation when element first appears in the DOM using
     *    [Animate.css](https://daneden.github.io/animate.css/). Otherwise you can
     *    simply use `fade-enter-done` for defining both cases.
     *
     * Each individual classNames can also be specified independently like:
     *
     * ```js
     * classNames={{
     *  appear: 'my-appear',
     *  appearActive: 'my-active-appear',
     *  appearDone: 'my-done-appear',
     *  enter: 'my-enter',
     *  enterActive: 'my-active-enter',
     *  enterDone: 'my-done-enter',
     *  exit: 'my-exit',
     *  exitActive: 'my-active-exit',
     *  exitDone: 'my-done-exit',
     * }}
     * ```
     *
     * If you want to set these classes using CSS Modules:
     *
     * ```js
     * import styles from './styles.css';
     * ```
     *
     * you might want to use camelCase in your CSS file, that way could simply
     * spread them instead of listing them one by one:
     *
     * ```js
     * classNames={{ ...styles }}
     * ```
     *
     * @type {string | {
     *  appear?: string,

   * The animation classNames applied to the component as it appears, enters,

   *
   * - `fade-appear`, `fade-appear-active`, `fade-appear-done`
   * - `fade-enter`, `fade-enter-active`, `fade-enter-done`
   * - `fade-exit`, `fade-exit-active`, `fade-exit-done`
   *
   * A few details to note about how these classes are applied:
   *
   * 1. They are _joined_ with the ones that are already defined on the child
   *    component, so if you want to add some base styles, you can use
   *    `className` without worrying that it will be overridden.
   *
   * 2. If the transition component mounts with `in={false}`, no classes are
   *    applied yet. You might be expecting `*-exit-done`, but if you think
   *    about it, a component cannot finish exiting if it hasn't entered yet.
   *
   * 2. `fade-appear-done` and `fade-enter-done` will _both_ be applied. This
   *    allows you to define different behavior for when appearing is done and
   *    when regular entering is done, using selectors like
   *    `.fade-enter-done:not(.fade-appear-done)`. For example, you could apply
   *    an epic entrance animation when element first appears in the DOM using
   *    [Animate.css](https://daneden.github.io/animate.css/). Otherwise you can
   *    simply use `fade-enter-done` for defining both cases.
   *
   * Each individual classNames can also be specified independently like:
   *
   * ```js
   * classNames={{
   *  appear: 'my-appear',
   *  appearActive: 'my-active-appear',
   *  appearDone: 'my-done-appear',
   *  enter: 'my-enter',
   *  enterActive: 'my-active-enter',
   *  enterDone: 'my-done-enter',
   *  exit: 'my-exit',
   *  exitActive: 'my-active-exit',
   *  exitDone: 'my-done-exit',
   * }}
   * ```
   *
   * If you want to set these classes using CSS Modules:
   *
   * ```js
   * import styles from './styles.css';
   * ```
   *
   * you might want to use camelCase in your CSS file, that way could simply
   * spread them instead of listing them one by one:
   *
   * ```js
   * classNames={{ ...styles }}
   * ```
   *
   * @type {string | {
   *  appear?: string,
   *  appearActive?: string,
   *  appearDone?: string,
   *  enter?: string,
   *  enterActive?: string,
   *  enterDone?: string,
   *  exit?: string,
   *  exitActive?: string,
   *  exitDone?: string,

/**
 * 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, but can also
 * be used to describe in-place transition states as well.
 *
 * ---
 *
 * **Note**: `Transition` is a platform-agnostic base component. If you're using
 * transitions in CSS, you'll probably want to use
 * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)
 * instead. It inherits all the features of `Transition`, but contains
 * additional features necessary to play nice with CSS transitions (hence the
 * name of the component).
 *
 * ---
 *
 * By default the `Transition` component does not alter the behavior of the
 * component it renders, it only tracks "enter" and "exit" states for the
 * components. It's up to you to give meaning and effect to those states. For
 * example we can add styles to a component when it enters or exits:
 *
 * ```jsx
 * import { Transition } from 'react-transition-group';
 *
 * const duration = 300;
 *
 * const defaultStyle = {
 *   transition: `opacity ${duration}ms ease-in-out`,
 *   opacity: 0,
 * }
 *
 * const transitionStyles = {
 *   entering: { opacity: 1 },
 *   entered:  { opacity: 1 },
 *   exiting:  { opacity: 0 },
 *   exited:  { opacity: 0 },
 * };
 *
 * const Fade = ({ in: inProp }) => (
 *   <Transition in={inProp} timeout={duration}>
 *     {state => (
 *       <div style={{
 *         ...defaultStyle,
 *         ...transitionStyles[state]
 *       }}>
 *         I'm a fade Transition!
 *       </div>
 *     )}
 *   </Transition>
 * );
 * ```
 *
 * There are 4 main states a Transition can be in:
 *  - `'entering'`
 *  - `'entered'`
 *  - `'exiting'`
 *  - `'exited'`
 *
 * Transition state is toggled via the `in` prop. When `true` the component
 * begins the "Enter" stage. During this stage, the component will shift from
 * its current transition state, to `'entering'` for the duration of the
 * transition and then to the `'entered'` stage once it's complete. Let's take
 * the following example (we'll use the
 * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):
 *
 * ```jsx
 * function App() {
 *   const [inProp, setInProp] = useState(false);
 *   return (
 *     <div>
 *       <Transition in={inProp} timeout={500}>
 *         {state => (
 *           // ...
 *         )}
 *       </Transition>
 *       <button onClick={() => setInProp(true)}>
 *         Click to Enter
 *       </button>
 *     </div>
 *   );
 * }
 * ```
 *
 * When the button is clicked the component will shift to the `'entering'` state
 * and stay there for 500ms (the value of `timeout`) before it finally switches
 * to `'entered'`.
 *
 * When `in` is `false` the same thing happens except the state moves from
 * `'exiting'` to `'exited'`.

   * The animation classNames applied to the component as it appears, enters,
   * exits or has finished the transition. A single name can be provided, which
   * will be suffixed for each stage, e.g. `classNames="fade"` applies:
   *
   * - `fade-appear`, `fade-appear-active`, `fade-appear-done`
   * - `fade-enter`, `fade-enter-active`, `fade-enter-done`
   * - `fade-exit`, `fade-exit-active`, `fade-exit-done`
   *
   * A few details to note about how these classes are applied:
   *
   * 1. They are _joined_ with the ones that are already defined on the child
   *    component, so if you want to add some base styles, you can use
   *    `className` without worrying that it will be overridden.
   *
   * 2. If the transition component mounts with `in={false}`, no classes are
   *    applied yet. You might be expecting `*-exit-done`, but if you think
   *    about it, a component cannot finish exiting if it hasn't entered yet.
   *
   * 2. `fade-appear-done` and `fade-enter-done` will _both_ be applied. This
   *    allows you to define different behavior for when appearing is done and
   *    when regular entering is done, using selectors like
   *    `.fade-enter-done:not(.fade-appear-done)`. For example, you could apply
   *    an epic entrance animation when element first appears in the DOM using
   *    [Animate.css](https://daneden.github.io/animate.css/). Otherwise you can
   *    simply use `fade-enter-done` for defining both cases.
   *
   * Each individual classNames can also be specified independently like:
   *
   * ```js
   * classNames={{
   *  appear: 'my-appear',
   *  appearActive: 'my-active-appear',
   *  appearDone: 'my-done-appear',
   *  enter: 'my-enter',
   *  enterActive: 'my-active-enter',
   *  enterDone: 'my-done-enter',
   *  exit: 'my-exit',
   *  exitActive: 'my-active-exit',
   *  exitDone: 'my-done-exit',
   * }}
   * ```
   *
   * If you want to set these classes using CSS Modules:
   *
   * ```js
   * import styles from './styles.css';
   * ```
   *
   * you might want to use camelCase in your CSS file, that way could simply
   * spread them instead of listing them one by one:
   *
   * ```js
   * classNames={{ ...styles }}
   * ```
   *
   * @type {string | {
   *  appear?: string,
   *  appearActive?: string,
   *  appearDone?: string,
   *  enter?: string,
   *  enterActive?: string,
   *  enterDone?: string,
   *  exit?: string,
