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 ${duration}ms ease-in-out`,\n * opacity: 0,\n * }\n *\n * const transitionStyles = {\n * entering: { opacity: 1 },\n * entered: { opacity: 1 },\n * exiting: { opacity: 0 },\n * exited: { opacity: 0 },\n * };\n *\n * const Fade = ({ in: inProp }) => (\n *
\n * {state => (\n * \n * I'm a fade Transition!\n *
\n * )}\n * \n * );\n * ```\n *\n * There are 4 main states a Transition can be in:\n * - `'entering'`\n * - `'entered'`\n * - `'exiting'`\n * - `'exited'`\n *\n * Transition state is toggled via the `in` prop. When `true` the component\n * begins the \"Enter\" stage. During this stage, the component will shift from\n * its current transition state, to `'entering'` for the duration of the\n * transition and then to the `'entered'` stage once it's complete. Let's take\n * the following example (we'll use the\n * [useState](https://reactjs.org/docs/hooks-reference.html#usestate) hook):\n *\n * ```jsx\n * function App() {\n * const [inProp, setInProp] = useState(false);\n * return (\n *
\n * \n * {state => (\n * // ...\n * )}\n * \n * \n *
\n * );\n * }\n * ```\n *\n * When the button is clicked the component will shift to the `'entering'` state\n * and stay there for 500ms (the value of `timeout`) before it finally switches\n * to `'entered'`.\n *\n * When `in` is `false` the same thing happens except the state moves from\n * `'exiting'` to `'exited'`.\n */\n\nvar Transition = /*#__PURE__*/function (_React$Component) {\n _inheritsLoose(Transition, _React$Component);\n\n function Transition(props, context) {\n var _this;\n\n _this = _React$Component.call(this, props, context) || this;\n var parentGroup = context; // In the context of a TransitionGroup all enters are really appears\n\n var appear = parentGroup && !parentGroup.isMounting ? props.enter : props.appear;\n var initialStatus;\n _this.appearStatus = null;\n\n if (props.in) {\n if (appear) {\n initialStatus = EXITED;\n _this.appearStatus = ENTERING;\n } else {\n initialStatus = ENTERED;\n }\n } else {\n if (props.unmountOnExit || props.mountOnEnter) {\n initialStatus = UNMOUNTED;\n } else {\n initialStatus = EXITED;\n }\n }\n\n _this.state = {\n status: initialStatus\n };\n _this.nextCallback = null;\n return _this;\n }\n\n Transition.getDerivedStateFromProps = function getDerivedStateFromProps(_ref, prevState) {\n var nextIn = _ref.in;\n\n if (nextIn && prevState.status === UNMOUNTED) {\n return {\n status: EXITED\n };\n }\n\n return null;\n } // getSnapshotBeforeUpdate(prevProps) {\n // let nextStatus = null\n // if (prevProps !== this.props) {\n // const { status } = this.state\n // if (this.props.in) {\n // if (status !== ENTERING && status !== ENTERED) {\n // nextStatus = ENTERING\n // }\n // } else {\n // if (status === ENTERING || status === ENTERED) {\n // nextStatus = EXITING\n // }\n // }\n // }\n // return { nextStatus }\n // }\n ;\n\n var _proto = Transition.prototype;\n\n _proto.componentDidMount = function componentDidMount() {\n this.updateStatus(true, this.appearStatus);\n };\n\n _proto.componentDidUpdate = function componentDidUpdate(prevProps) {\n var nextStatus = null;\n\n if (prevProps !== this.props) {\n var status = this.state.status;\n\n if (this.props.in) {\n if (status !== ENTERING && status !== ENTERED) {\n nextStatus = ENTERING;\n }\n } else {\n if (status === ENTERING || status === ENTERED) {\n nextStatus = EXITING;\n }\n }\n }\n\n this.updateStatus(false, nextStatus);\n };\n\n _proto.componentWillUnmount = function componentWillUnmount() {\n this.cancelNextCallback();\n };\n\n _proto.getTimeouts = function getTimeouts() {\n var timeout = this.props.timeout;\n var exit, enter, appear;\n exit = enter = appear = timeout;\n\n if (timeout != null && typeof timeout !== 'number') {\n exit = timeout.exit;\n enter = timeout.enter; // TODO: remove fallback for next major\n\n appear = timeout.appear !== undefined ? timeout.appear : enter;\n }\n\n return {\n exit: exit,\n enter: enter,\n appear: appear\n };\n };\n\n _proto.updateStatus = function updateStatus(mounting, nextStatus) {\n if (mounting === void 0) {\n mounting = false;\n }\n\n if (nextStatus !== null) {\n // nextStatus will always be ENTERING or EXITING.\n this.cancelNextCallback();\n\n if (nextStatus === ENTERING) {\n if (this.props.unmountOnExit || this.props.mountOnEnter) {\n var node = this.props.nodeRef ? this.props.nodeRef.current : ReactDOM.findDOMNode(this); // https://github.com/reactjs/react-transition-group/pull/749\n // With unmountOnExit or mountOnEnter, the enter animation should happen at the transition between `exited` and `entering`.\n // To make the animation happen, we have to separate each rendering and avoid being processed as batched.\n\n if (node) forceReflow(node);\n }\n\n this.performEnter(mounting);\n } else {\n this.performExit();\n }\n } else if (this.props.unmountOnExit && this.state.status === EXITED) {\n this.setState({\n status: UNMOUNTED\n });\n }\n };\n\n _proto.performEnter = function performEnter(mounting) {\n var _this2 = this;\n\n var enter = this.props.enter;\n var appearing = this.context ? this.context.isMounting : mounting;\n\n var _ref2 = this.props.nodeRef ?

Sometimes it's called a \"filter\",\n// but that's not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored. (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it's not a\n// necessarily symmetric or synchronous transformation. For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here's how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes. When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there's a lot of pending writes\n// buffered up. When you call read(), that calls _read(n) until\n// there's enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer. When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb's as it consumes chunks. If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit 'readable' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk. However,\n// a pathological inflate type of transform can cause excessive buffering\n// here. For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output. In this case, you could write a very small\n// amount of input, and end up with a very large amount of output. In\n// such a pathological inflating mechanism, there'd be no way to tell\n// the system to stop doing the transform. A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n'use strict';\n\nmodule.exports = Transform;\n\nvar _require$codes = require('../errors').codes,\n ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED,\n ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK,\n ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING,\n ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0;\n\nvar Duplex = require('./_stream_duplex');\n\nrequire('inherits')(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n var ts = this._transformState;\n ts.transforming = false;\n var cb = ts.writecb;\n\n if (cb === null) {\n return this.emit('error', new ERR_MULTIPLE_CALLBACK());\n }\n\n ts.writechunk = null;\n ts.writecb = null;\n if (data != null) // single equals check for both `null` and `undefined`\n this.push(data);\n cb(er);\n var rs = this._readableState;\n rs.reading = false;\n\n if (rs.needReadable || rs.length < rs.highWaterMark) {\n this._read(rs.highWaterMark);\n }\n}\n\nfunction Transform(options) {\n if (!(this instanceof Transform)) return new Transform(options);\n Duplex.call(this, options);\n this._transformState = {\n afterTransform: afterTransform.bind(this),\n needTransform: false,\n transforming: false,\n writecb: null,\n writechunk: null,\n writeencoding: null\n }; // start out asking for a readable event once data is transformed.\n\n this._readableState.needReadable = true; // we have implemented the _read method, and done the other things\n // that Readable wants before the first _read call, so unset the\n // sync guard flag.\n\n this._readableState.sync = false;\n\n if (options) {\n if (typeof options.transform === 'function') this._transform = options.transform;\n if (typeof options.flush === 'function') this._flush = options.flush;\n } // When the writable side finishes, then flush out anything remaining.\n\n\n this.on('prefinish', prefinish);\n}\n\nfunction prefinish() {\n var _this = this;\n\n if (typeof this._flush === 'function' && !this._readableState.destroyed) {\n this._flush(function (er, data) {\n done(_this, er, data);\n });\n } else {\n done(this, null, null);\n }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n this._transformState.needTransform = false;\n return Duplex.prototype.push.call(this, chunk, encoding);\n}; // This is the part where you do stuff!\n// override this function in implementation classes.\n// 'chunk' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.
