/**
|
||
|
* A transition component inspired by the excellent
|
||
|
* [ng-animate](https://docs.angularjs.org/api/ngAnimate) library, you should
|
||
|
* use it if you're using CSS transitions or animations. It's built upon the
|
||
|
* [`Transition`](https://reactcommunity.org/react-transition-group/transition)
|
||
|
* component, so it inherits all of its props.
|
||
|
*
|
||
|
* `CSSTransition` applies a pair of class names during the `appear`, `enter`,
|
||
|
* and `exit` states of the transition. The first class is applied and then a
|
||
|
* second `*-active` class in order to activate the CSS transition. After the
|
||
|
* transition, matching `*-done` class names are applied to persist the
|
||
|
* transition state.
|
||
|
*
|
||
|
* ```jsx
|
||
|
* function App() {
|
||
|
* const [inProp, setInProp] = useState(false);
|
||
|
* return (
|
||
|
* <div>
|
||
|
* <CSSTransition in={inProp} timeout={200} classNames="my-node">
|
||
|
* <div>
|
||
|
* {"I'll receive my-node-* classes"}
|
||
|
* </div>
|
||
|
* </CSSTransition>
|
||
|
* <button type="button" onClick={() => setInProp(true)}>
|
||
|
* Click to Enter
|
||
|
* </button>
|
||
|
* </div>
|
||
|
* );
|
||
|
* }
|
||
|
* ```
|
||
|
*
|
||
|
* When the `in` prop is set to `true`, the child component will first receive
|
||
|
* the class `example-enter`, then the `example-enter-active` will be added in
|
||
|
* the next tick. `CSSTransition` [forces a
|
||
|
* reflow](https://github.com/reactjs/react-transition-group/blob/5007303e729a74be66a21c3e2205e4916821524b/src/CSSTransition.js#L208-L215)
|
||
|
* between before adding the `example-enter-active`. This is an important trick
|
||
|
* because it allows us to transition between `example-enter` and
|
||
|
* `example-enter-active` even though they were added immediately one after
|
||
|
* another. Most notably, this is what makes it possible for us to animate
|
||
|
* _appearance_.
|
||
|
*
|
||
|
* ```css
|
||
|
* .my-node-enter {
|
||
|
* opacity: 0;
|
||
|
* }
|
||
|
* .my-node-enter-active {
|
||
|
* opacity: 1;
|
||
|
* transition: opacity 200ms;
|
||
|
* }
|
||
|
* .my-node-exit {
|
||
|
* opacity: 1;
|
||
|
* }
|
||
|
* .my-node-exit-active {
|
||
|
* opacity: 0;
|
||
|
* transition: opacity 200ms;
|
||
|
* }
|
||
|
* ```
|
||
|
*
|
||
|
* `*-active` classes represent which styles you want to animate **to**, so it's
|
||
|
* important to add `transition` declaration only to them, otherwise transitions
|
||
|
* might not behave as intended! This might not be obvious when the transitions
|
||
|
* are symmetrical, i.e. when `*-enter-active` is the same as `*-exit`, like in
|
||
|
* the example above (minus `transition`), but it becomes apparent in more
|
||
|
* complex transitions.
|
||
|
*
|
||
|
* **Note**: If you're using the
|
||
|
* [`appear`](http://reactcommunity.org/react-transition-group/transition#Transition-prop-appear)
|
||
|
* prop, make sure to define styles for `.appear-*` classes as well.

/**
|
||
|
* 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,
|
||
|
