/**
|
||||
* 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'`.
