-
-## [4.4.3](https://github.com/reactjs/react-transition-group/compare/v4.4.2...v4.4.3) (2022-07-30)
-
-
-### Bug Fixes
-
-* enter animations with mountOnEnter or unmountOnExit ([#749](https://github.com/reactjs/react-transition-group/issues/749)) ([51bdceb](https://github.com/reactjs/react-transition-group/commit/51bdceb96c8b6a79f417c32326ef1b31160edb97))
-
-## [4.4.2](https://github.com/reactjs/react-transition-group/compare/v4.4.1...v4.4.2) (2021-05-29)
-
-
-### Bug Fixes
-
-* `nodeRef` prop type for cross-realm elements ([#732](https://github.com/reactjs/react-transition-group/issues/732)) ([8710c01](https://github.com/reactjs/react-transition-group/commit/8710c01549e09f55eeefec2aadb3af0a23a00f82))
-
-## [4.4.1](https://github.com/reactjs/react-transition-group/compare/v4.4.0...v4.4.1) (2020-05-06)
-
-
-### Bug Fixes
-
-* transition SSR ([#619](https://github.com/reactjs/react-transition-group/issues/619)) ([2722bb6](https://github.com/reactjs/react-transition-group/commit/2722bb6b755943b8292f0f2bc2fdca55df5c28f0))
-
-# [4.4.0](https://github.com/reactjs/react-transition-group/compare/v4.3.0...v4.4.0) (2020-05-05)
-
-
-### Features
-
-* add `nodeRef` alternative instead of internal `findDOMNode` ([#559](https://github.com/reactjs/react-transition-group/issues/559)) ([85016bf](https://github.com/reactjs/react-transition-group/commit/85016bfddd3831e6d7bb27926f9f178d25502913))
- - react-transition-group internally uses `findDOMNode`, which is deprecated and produces warnings in [Strict Mode](https://reactjs.org/docs/strict-mode.html), so now you can optionally pass `nodeRef` to `Transition` and `CSSTransition`, it's a ref object that should point to the transitioning child:
-
- ```jsx
- import React from "react"
- import { CSSTransition } from "react-transition-group"
-
- const MyComponent = () => {
- const nodeRef = React.useRef(null)
- return (
-
-
Fade
-
- )
- }
- ```
-### Bug Fixes
-
-* set the values of constants attached to `Transition` to match the exported ones ([#554](https://github.com/reactjs/react-transition-group/pull/554))

-# Migration Guide from v1 to v2
-
-_A few notes to help with migrating from v1 to v2._
-
-The `` component has been removed. A `` component has been added for use with the new `` component to accomplish the same tasks.
-
-### tl;dr:
-
-- `transitionName` -> `classNames`
-- `transitionEnterTimeout` and `transitionLeaveTimeout` -> `timeout={{ exit, enter }}`
-- `transitionAppear` -> `appear`
-- `transitionEnter` -> `enter`
-- `transitionLeave` -> `exit`
-
-## Walkthrough
-
-Let's take the [original docs example](https://github.com/reactjs/react-transition-group/tree/v1-stable/#high-level-api-csstransitiongroup) and migrate it.
-
-Starting with this CSS:
-
-```css
-.example-enter {
- opacity: 0.01;
-}
-
-.example-enter.example-enter-active {
- opacity: 1;
- transition: opacity 500ms ease-in;
-}
-
-.example-leave {
- opacity: 1;
-}
-
-.example-leave.example-leave-active {
- opacity: 0.01;
- transition: opacity 300ms ease-in;
-}
-```
-
-And this component:
-
-```js
-class TodoList extends React.Component {
- constructor(props) {
- super(props);
- this.state = {items: ['hello', 'world', 'click', 'me']};
- this.handleAdd = this.handleAdd.bind(this);
- }
-
- handleAdd() {
- const newItems = this.state.items.concat([
- prompt('Enter some text')
- ]);
- this.setState({items: newItems});
- }
-
- handleRemove(i) {
- let newItems = this.state.items.slice();
- newItems.splice(i, 1);
- this.setState({items: newItems});
- }
-
- render() {
- const items = this.state.items.map((item, i) => (
-
this.handleRemove(i)}>
- {item}
-
- ));
-
- return (
-
-
-
- {items}
-
-
- );
- }
-}
-```
-
-The most straightforward way to migrate is to use `` instead of ``:
-
-```diff
- render() {
- const items = this.state.items.map((item, i) => (
-
this.handleRemove(i)}>
- {item}
-
- ));
-
- return (
-
-
--
-+
- {items}
--
-+
-
- )
- }
-```
-
-That doesn't get us much, since we haven't included anything to do the animation. For that, we'll need to wrap each item in a ``. First, though, let's adjust our CSS:
-
-```diff
- .example-enter {
- opacity: 0.01;
- }
-
- .example-enter.example-enter-active {
- opacity: 1;
- transition: opacity 500ms ease-in;
- }
-
--.example-leave {
-+.example-exit {
- opacity: 1;
- }
-
--.example-leave.example-leave-active {
-+.example-exit.example-exit-active {
- opacity: 0.01;
- transition: opacity 300ms ease-in;
- }
-```
-
-All we did was replace `leave` with `exit`. v2 uses "exit" instead of "leave" to be more symmetric, avoiding awkwardness with English tenses (like with "entered" and "leaved").
-
-Now we add the `` component:
-
-```diff
- render() {
- const items = this.state.items.map((item, i) => (
-+
-
this.handleRemove(i)}>
- {item}
-
-+
- ));
-
- return (
-
-
-
- {items}
-
-
- )
- }
-```
-
-Note that we replaced `transitionName` with `classNames`. `` otherwise has essentially the same signature as ``. We also replaced `transitionEnterTimeout` and `transitionLeaveTimeout` with a single `timeout` prop with an object.
-
-> **Hint:** If your enter and exit timeouts are the same you can use the shorthand `timeout={500}`.
-
-If we want to make this a bit more encapsulated, we can wrap our `` into a separate component for reuse later:
-
-```js
-const FadeTransition = (props) => (
-
-);
-```
-
-We can then use it like:
-
-```diff
- render() {
- const items = this.state.items.map((item, i) => (
--
-+
-

Usage with React Router
\n
\n People often want to animate route transitions, which can result in\n delightful UX when used in moderation. The first instinct might be to\n use wrap all routes in TransitionGroup, but that approach\n requires hacks and falls apart easily when used with trickier components\n of React Router like Redirect. You should use{' '}\n CSSTransition for each route and manage their{' '}\n in prop on their own.\n
\n
\n The main challenge is the exit transition because React\n Router changes to a new route instantly, so we need to keep the old\n route around long enough to transition out of it. Fortunately,{' '}\n Route\n 's children prop also accepts a function, which\n should not be confused with the render prop! Unlike the{' '}\n render prop, children function runs whether\n the route is matched or not. React Router passes the object containing a{' '}\n match object, which exists if the route matches, otherwise\n it's null. This enables us to manage the in{' '}\n prop of CSSTransition based on the presence of{' '}\n match.\n
\n
\n Exit transitions will cause the content of routes to linger until they\n disappear, which might pose some styling challenges. Make sure that\n routes don't affect each other's layout, for example you can remove them\n from the flow of the document by using absolute or fixed positioning.\n
\n
\n
\n Note: When using React Transition Group with React Router, make\n sure to avoid using the Switch component because it only\n executes the first matching Route.

Testing Components with Transitions
\n
\n In some situations, like visual snapshot testing, it's helpful to\n disable transitions so they don't complicate the test, or introduce\n abitrary waits. To make this easier react-transition-group{' '}\n exposes a way to globally toggle transitions. When set,{' '}\n all transitions, when toggled, will immediately switch\n to their entered or exited states as appropriate.\n
\n Note: This does not automatically disable\n animations. It only disabled waits in Transition. You may\n also have to disable animation as appropriate for the library.\n example:{' '}\n Mocking in Velocity.js\n

React Transition Group

\n Since react-transition-group is fairly small, the overhead of\n including the library in your application is negligible. However,\n in situations where it may be useful to benefit from an external\n CDN when bundling, link to the following CDN:{' '}\n \n https://unpkg.com/react-transition-group/dist/react-transition-group.js\n \n

Most commonly\n * it's used to animate the mounting and unmounting of a component, but can also\n * be used to describe in-place transition states as well.\n *\n * ---\n *\n * **Note**: `Transition` is a platform-agnostic base component. If you're using\n * transitions in CSS, you'll probably want to use\n * [`CSSTransition`](https://reactcommunity.org/react-transition-group/css-transition)\n * instead. It inherits all the features of `Transition`, but contains\n * additional features necessary to play nice with CSS transitions (hence the\n * name of the component).\n *\n * ---\n *\n * By default the `Transition` component does not alter the behavior of the\n * component it renders, it only tracks \"enter\" and \"exit\" states for the\n * components. It's up to you to give meaning and effect to those states. For\n * example we can add styles to a component when it enters or exits:\n *\n * ```jsx\n * import { Transition } from 'react-transition-group';\n *\n * const duration = 300;\n *\n * const defaultStyle = {\n * transition: `opacity ${duration}ms ease-in-out`,\n * opacity: 0,\n * }\n *\n * const transitionStyles = {\n * entering: { opacity: 1 },\n * entered: { opacity: 1 },\n * exiting: { opacity: 0 },\n * exited: { opacity: 0 },\n * };\n *\n * const Fade = ({ in: inProp }) => (\n * \n * {state => (\n *
\n * I'm a fade Transition!\n *
\n * )}\n * \n * );\n * ```\n *\n * There are 4 main states a Transition can be in:\n * - `'entering'`\n * - `'entered'`\n * - `'exiting'`\n * - `'exited'`\n *\n * Transition state is toggled via the `in` prop. When `true` the component\n * begins the \"Enter\" stage. During this stage, the component will shift from\n * its current transition state, to `'entering'` for the duration of the\n * transition and then to the `'entered'` stage once it's complete. Let's take\n * the following example (we'll use the\n * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):\n *\n * ```jsx\n * function App() {\n * const [inProp, setInProp] = useState(false);\n * return (\n *
- 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, link to the following CDN:{' '}
-
- https://unpkg.com/react-transition-group/dist/react-transition-group.js
-
-
- In some situations, like visual snapshot testing, it's helpful to
- disable transitions so they don't complicate the test, or introduce
- abitrary waits. To make this easier react-transition-group{' '}
- exposes a way to globally toggle transitions. When set,{' '}
- all transitions, when toggled, will immediately switch
- to their entered or exited states as appropriate.
-
- Note: This does not automatically disable
- animations. It only disabled waits in Transition. You may
- also have to disable animation as appropriate for the library.
- example:{' '}
- Mocking in Velocity.js
-
- People often want to animate route transitions, which can result in
- delightful UX when used in moderation. The first instinct might be to
- use wrap all routes in TransitionGroup, but that approach
- requires hacks and falls apart easily when used with trickier components
- of React Router like Redirect. You should use{' '}
- CSSTransition for each route and manage their{' '}
- in prop on their own.
-
-
- The main challenge is the exit transition because React
- Router changes to a new route instantly, so we need to keep the old
- route around long enough to transition out of it. Fortunately,{' '}
- Route
- 's children prop also accepts a function, which
- should not be confused with the render prop! Unlike the{' '}
- render prop, children function runs whether
- the route is matched or not. React Router passes the object containing a{' '}
- match object, which exists if the route matches, otherwise
- it's null. This enables us to manage the in{' '}
- prop of CSSTransition based on the presence of{' '}
- match.
-
-
- Exit transitions will cause the content of routes to linger until they
- disappear, which might pose some styling challenges. Make sure that
- routes don't affect each other's layout, for example you can remove them
- from the flow of the document by using absolute or fixed positioning.
-
-
-
- Note: When using React Transition Group with React Router, make
- sure to avoid using the Switch component because it only
- executes the first matching Route. This would make the
- exit transition impossible to achieve because the exiting route will
- no longer match the current URL and the children function
- won't execute.
