+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOM.render(<MyComponent />, node);
+```
+
+### On the server
+
+```js
+var React = require('react');
+var ReactDOMServer = require('react-dom/server');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOMServer.renderToString(<MyComponent />);
+```

+# react
+
+An npm package to get you immediate access to [React](https://facebook.github.io/react/),
+without also requiring the JSX transformer. This is especially useful for cases where you
+want to [`browserify`](https://github.com/substack/node-browserify) your module using
+`React`.
+
+**Note:** by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages.
+
+To use React in production mode, set the environment variable `NODE_ENV` to `production`. A minifier that performs dead-code elimination such as [UglifyJS](https://github.com/mishoo/UglifyJS2) is recommended to completely remove the extra code present in development mode.
+
+## Example Usage
+
+```js
+var React = require('react');
+
+// Addons are in separate packages:
+var createFragment = require('react-addons-create-fragment');
+var immutabilityHelpers = require('react-addons-update');
+var CSSTransitionGroup = require('react-addons-css-transition-group');
+```
+
+For a complete list of addons visit the [addons documentation page](https://facebook.github.io/react/docs/addons.html).

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occuring, the responder lock can be transfered to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderID`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendents of the
+ *   *current* responderID, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

+/**
+ * A note about event ordering in the `EventPluginHub`.
+ *
+ * Suppose plugins are injected in the following order:
+ *
+ * `[R, S, C]`
+ *
+ * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+ * `onClick` etc) and `R` is `ResponderEventPlugin`.
+ *
+ * "Deferred-Dispatched Events":
+ *
+ * - The current event plugin system will traverse the list of injected plugins,
+ *   in order, and extract events by collecting the plugin's return value of
+ *   `extractEvents()`.
+ * - These events that are returned from `extractEvents` are "deferred
+ *   dispatched events".
+ * - When returned from `extractEvents`, deferred-dispatched events contain an
+ *   "accumulation" of deferred dispatches.
+ * - These deferred dispatches are accumulated/collected before they are
+ *   returned, but processed at a later time by the `EventPluginHub` (hence the
+ *   name deferred).
+ *
+ * In the process of returning their deferred-dispatched events, event plugins
+ * themselves can dispatch events on-demand without returning them from
+ * `extractEvents`. Plugins might want to do this, so that they can use event
+ * dispatching as a tool that helps them decide which events should be extracted
+ * in the first place.
+ *
+ * "On-Demand-Dispatched Events":
+ *
+ * - On-demand-dispatched events are not returned from `extractEvents`.
+ * - On-demand-dispatched events are dispatched during the process of returning
+ *   the deferred-dispatched events.
+ * - They should not have side effects.
+ * - They should be avoided, and/or eventually be replaced with another
+ *   abstraction that allows event plugins to perform multiple "rounds" of event
+ *   extraction.
+ *
+ * Therefore, the sequence of event dispatches becomes:
+ *
+ * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+ * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+ * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+ * - `R`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `S`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `C`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ *
+ * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+ * on-demand dispatch returns `true` (and some other details are satisfied) the
+ * `onResponderGrant` deferred dispatched event is returned from
+ * `extractEvents`. The sequence of dispatch executions in this case
+ * will appear as follows:
+ *
+ * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+ * - `touchStartCapture`       (`EventPluginHub` dispatches as usual)
+ * - `touchStart`              (`EventPluginHub` dispatches as usual)
+ * - `responderGrant/Reject`   (`EventPluginHub` dispatches as usual)
+ *
+ * @param {string} topLevelType Record from `EventConstants`.

+ * `Transaction` creates a black box that is able to wrap any method such that
+ * certain invariants are maintained before and after the method is invoked
+ * (Even if an exception is thrown while invoking the wrapped method). Whoever
+ * instantiates a transaction can provide enforcers of the invariants at
+ * creation time. The `Transaction` class itself will supply one additional
+ * automatic invariant for you - the invariant that any transaction instance
+ * should not be run while it is already being run. You would typically create a
+ * single instance of a `Transaction` for reuse multiple times, that potentially
+ * is used to wrap several different methods. Wrappers are extremely simple -
+ * they only require implementing two methods.

+ * - (Future use case): Layout calculations before and after DOM updates.

+ * Transactional plugin API:

+# `react-dom`
+
+This package serves as the entry point of the DOM-related rendering paths. It is intended to be paired with the isomorphic React, which will be shipped as `react` to npm.
+
+## Installation
+
+```sh
+npm install react react-dom
+```
+
+## Usage
+
+### In the browser
+
+```js
+var React = require('react');
+var ReactDOM = require('react-dom');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOM.render(<MyComponent />, node);
+```
+
+### On the server
+
+```js
+var React = require('react');
+var ReactDOMServer = require('react-dom/server');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOMServer.renderToString(<MyComponent />);
+```
+
+## API
+
+### `react-dom`
+
+- `findDOMNode`
+- `render`
+- `unmountComponentAtNode`
+
+### `react-dom/server`
+
+- `renderToString`
+- `renderToStaticMarkup`

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+ * `Transaction` creates a black box that is able to wrap any method such that

+ * should not be run while it is already being run. You would typically create a
+ * single instance of a `Transaction` for reuse multiple times, that potentially
+ * is used to wrap several different methods. Wrappers are extremely simple -

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+ * `Transaction` creates a black box that is able to wrap any method such that

+ * should not be run while it is already being run. You would typically create a

+ * is used to wrap several different methods. Wrappers are extremely simple -

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occurring, the responder lock can be transferred to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderInst`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendants of the
+ *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

+/**
+ * A note about event ordering in the `EventPluginHub`.
+ *
+ * Suppose plugins are injected in the following order:
+ *
+ * `[R, S, C]`
+ *
+ * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+ * `onClick` etc) and `R` is `ResponderEventPlugin`.
+ *
+ * "Deferred-Dispatched Events":
+ *
+ * - The current event plugin system will traverse the list of injected plugins,
+ *   in order, and extract events by collecting the plugin's return value of
+ *   `extractEvents()`.
+ * - These events that are returned from `extractEvents` are "deferred
+ *   dispatched events".
+ * - When returned from `extractEvents`, deferred-dispatched events contain an
+ *   "accumulation" of deferred dispatches.
+ * - These deferred dispatches are accumulated/collected before they are
+ *   returned, but processed at a later time by the `EventPluginHub` (hence the
+ *   name deferred).
+ *
+ * In the process of returning their deferred-dispatched events, event plugins
+ * themselves can dispatch events on-demand without returning them from
+ * `extractEvents`. Plugins might want to do this, so that they can use event
+ * dispatching as a tool that helps them decide which events should be extracted
+ * in the first place.
+ *
+ * "On-Demand-Dispatched Events":
+ *
+ * - On-demand-dispatched events are not returned from `extractEvents`.
+ * - On-demand-dispatched events are dispatched during the process of returning
+ *   the deferred-dispatched events.
+ * - They should not have side effects.
+ * - They should be avoided, and/or eventually be replaced with another
+ *   abstraction that allows event plugins to perform multiple "rounds" of event
+ *   extraction.
+ *
+ * Therefore, the sequence of event dispatches becomes:
+ *
+ * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+ * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+ * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+ * - `R`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `S`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `C`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ *
+ * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+ * on-demand dispatch returns `true` (and some other details are satisfied) the
+ * `onResponderGrant` deferred dispatched event is returned from
+ * `extractEvents`. The sequence of dispatch executions in this case
+ * will appear as follows:
+ *
+ * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+ * - `touchStartCapture`       (`EventPluginHub` dispatches as usual)
+ * - `touchStart`              (`EventPluginHub` dispatches as usual)
+ * - `responderGrant/Reject`   (`EventPluginHub` dispatches as usual)

+ * `Transaction` creates a black box that is able to wrap any method such that
+ * certain invariants are maintained before and after the method is invoked
+ * (Even if an exception is thrown while invoking the wrapped method). Whoever
+ * instantiates a transaction can provide enforcers of the invariants at
+ * creation time. The `Transaction` class itself will supply one additional
+ * automatic invariant for you - the invariant that any transaction instance
+ * should not be run while it is already being run. You would typically create a
+ * single instance of a `Transaction` for reuse multiple times, that potentially
+ * is used to wrap several different methods. Wrappers are extremely simple -
+ * they only require implementing two methods.

+# `react-test-renderer`
+
+This package provides two React renderers that can be used for testing purposes:
+
+#### Test renderer
+
+Renders React components to pure JavaScript objects without depending on the DOM or a native mobile environment. This makes it easy to grab a snapshot of the "DOM tree" rendered by a React DOM or React Native component without using a browser or jsdom.
+
+```jsx
+const ReactTestRenderer = require('react-test-renderer');
+
+const renderer = ReactTestRenderer.create(
+  <Link page="https://www.facebook.com/">Facebook</Link>
+);
+
+console.log(renderer.toJSON());
+// { type: 'a',
+//   props: { href: 'https://www.facebook.com/' },
+//   children: [ 'Facebook' ] }
+```
+
+You can also use Jest's snapshot testing feature to automatically save a copy of the JSON tree to a file and check in your tests that it hasn't changed: http://facebook.github.io/jest/blog/2016/07/27/jest-14.html.
+
+#### Shallow renderer
+
+Shallow rendering lets you render a component "one level deep" and assert facts about what its render method returns, without worrying about the behavior of child components, which are not instantiated or rendered. This does not require a DOM.
+
+```jsx
+const ReactShallowRenderer = require('react-test-renderer/shallow');
+
+const renderer = new ReactShallowRenderer();
+renderer.render(<MyComponent />);
+
+const result = renderer.getRenderOutput();
+expect(result.type).toBe('div');
+expect(result.props.children).toEqual([
+  <span className="heading">Title</span>,
+  <Subcomponent foo="bar" />
+]);
+```
+
+This renderer was previously located in `react-addons-test-utils`.

+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occurring, the responder lock can be transferred to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderInst`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendants of the
+ *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

+/**
+ * A note about event ordering in the `EventPluginHub`.
+ *
+ * Suppose plugins are injected in the following order:
+ *
+ * `[R, S, C]`
+ *
+ * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+ * `onClick` etc) and `R` is `ResponderEventPlugin`.
+ *
+ * "Deferred-Dispatched Events":
+ *
+ * - The current event plugin system will traverse the list of injected plugins,
+ *   in order, and extract events by collecting the plugin's return value of
+ *   `extractEvents()`.
+ * - These events that are returned from `extractEvents` are "deferred
+ *   dispatched events".
+ * - When returned from `extractEvents`, deferred-dispatched events contain an
+ *   "accumulation" of deferred dispatches.
+ * - These deferred dispatches are accumulated/collected before they are
+ *   returned, but processed at a later time by the `EventPluginHub` (hence the
+ *   name deferred).
+ *
+ * In the process of returning their deferred-dispatched events, event plugins
+ * themselves can dispatch events on-demand without returning them from
+ * `extractEvents`. Plugins might want to do this, so that they can use event
+ * dispatching as a tool that helps them decide which events should be extracted
+ * in the first place.
+ *
+ * "On-Demand-Dispatched Events":
+ *
+ * - On-demand-dispatched events are not returned from `extractEvents`.
+ * - On-demand-dispatched events are dispatched during the process of returning
+ *   the deferred-dispatched events.
+ * - They should not have side effects.
+ * - They should be avoided, and/or eventually be replaced with another
+ *   abstraction that allows event plugins to perform multiple "rounds" of event
+ *   extraction.
+ *
+ * Therefore, the sequence of event dispatches becomes:
+ *
+ * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+ * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+ * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+ * - `R`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `S`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `C`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ *
+ * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+ * on-demand dispatch returns `true` (and some other details are satisfied) the
+ * `onResponderGrant` deferred dispatched event is returned from
+ * `extractEvents`. The sequence of dispatch executions in this case
+ * will appear as follows:
+ *
+ * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+ * - `touchStartCapture`       (`EventPluginHub` dispatches as usual)
+ * - `touchStart`              (`EventPluginHub` dispatches as usual)
+ * - `responderGrant/Reject`   (`EventPluginHub` dispatches as usual)

+ * `Transaction` creates a black box that is able to wrap any method such that
+ * certain invariants are maintained before and after the method is invoked
+ * (Even if an exception is thrown while invoking the wrapped method). Whoever
+ * instantiates a transaction can provide enforcers of the invariants at
+ * creation time. The `Transaction` class itself will supply one additional
+ * automatic invariant for you - the invariant that any transaction instance
+ * should not be run while it is already being run. You would typically create a
+ * single instance of a `Transaction` for reuse multiple times, that potentially
+ * is used to wrap several different methods. Wrappers are extremely simple -
+ * they only require implementing two methods.

+/**
+ * Summary of `ReactBrowserEventEmitter` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactEventListener, which is injected and can therefore support pluggable
+ *    event sources. This is the only work that occurs in the main thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginHub` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginHub` then dispatches the events.
+ *

+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occurring, the responder lock can be transferred to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderInst`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendants of the
+ *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

+/**
+ * A note about event ordering in the `EventPluginHub`.
+ *
+ * Suppose plugins are injected in the following order:
+ *
+ * `[R, S, C]`
+ *
+ * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+ * `onClick` etc) and `R` is `ResponderEventPlugin`.
+ *
+ * "Deferred-Dispatched Events":
+ *
+ * - The current event plugin system will traverse the list of injected plugins,
+ *   in order, and extract events by collecting the plugin's return value of
+ *   `extractEvents()`.
+ * - These events that are returned from `extractEvents` are "deferred
+ *   dispatched events".
+ * - When returned from `extractEvents`, deferred-dispatched events contain an
+ *   "accumulation" of deferred dispatches.
+ * - These deferred dispatches are accumulated/collected before they are
+ *   returned, but processed at a later time by the `EventPluginHub` (hence the
+ *   name deferred).
+ *
+ * In the process of returning their deferred-dispatched events, event plugins
+ * themselves can dispatch events on-demand without returning them from
+ * `extractEvents`. Plugins might want to do this, so that they can use event
+ * dispatching as a tool that helps them decide which events should be extracted
+ * in the first place.
+ *
+ * "On-Demand-Dispatched Events":
+ *
+ * - On-demand-dispatched events are not returned from `extractEvents`.
+ * - On-demand-dispatched events are dispatched during the process of returning
+ *   the deferred-dispatched events.
+ * - They should not have side effects.
+ * - They should be avoided, and/or eventually be replaced with another
+ *   abstraction that allows event plugins to perform multiple "rounds" of event
+ *   extraction.
+ *
+ * Therefore, the sequence of event dispatches becomes:
+ *
+ * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+ * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+ * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+ * - `R`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `S`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `C`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ *
+ * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+ * on-demand dispatch returns `true` (and some other details are satisfied) the
+ * `onResponderGrant` deferred dispatched event is returned from
+ * `extractEvents`. The sequence of dispatch executions in this case
+ * will appear as follows:
+ *
+ * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+ * - `touchStartCapture`       (`EventPluginHub` dispatches as usual)
+ * - `touchStart`              (`EventPluginHub` dispatches as usual)
+ * - `responderGrant/Reject`   (`EventPluginHub` dispatches as usual)

+ * `Transaction` creates a black box that is able to wrap any method such that
+ * certain invariants are maintained before and after the method is invoked
+ * (Even if an exception is thrown while invoking the wrapped method). Whoever
+ * instantiates a transaction can provide enforcers of the invariants at
+ * creation time. The `Transaction` class itself will supply one additional
+ * automatic invariant for you - the invariant that any transaction instance
+ * should not be run while it is already being run. You would typically create a
+ * single instance of a `Transaction` for reuse multiple times, that potentially
+ * is used to wrap several different methods. Wrappers are extremely simple -
+ * they only require implementing two methods.

+# react
+
+An npm package to get you immediate access to [React](https://facebook.github.io/react/),
+without also requiring the JSX transformer. This is especially useful for cases where you
+want to [`browserify`](https://github.com/substack/node-browserify) your module using
+`React`.
+
+**Note:** by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages.
+
+To use React in production mode, set the environment variable `NODE_ENV` to `production`. A minifier that performs dead-code elimination such as [UglifyJS](https://github.com/mishoo/UglifyJS2) is recommended to completely remove the extra code present in development mode.
+
+## Example Usage
+
+```js
+var React = require('react');
+```

+# `react-dom`
+
+This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as `react` to npm.
+
+## Installation
+
+```sh
+npm install react react-dom
+```
+
+## Usage
+
+### In the browser
+
+```js
+var React = require('react');
+var ReactDOM = require('react-dom');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOM.render(<MyComponent />, node);
+```
+
+### On the server
+
+```js
+var React = require('react');
+var ReactDOMServer = require('react-dom/server');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOMServer.renderToString(<MyComponent />);
+```
+
+## API
+
+### `react-dom`
+
+- `findDOMNode`
+- `render`
+- `unmountComponentAtNode`
+
+### `react-dom/server`
+
+- `renderToString`
+- `renderToStaticMarkup`

+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occurring, the responder lock can be transferred to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderInst`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendants of the
+ *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

+/**
+ * A note about event ordering in the `EventPluginRegistry`.
+ *
+ * Suppose plugins are injected in the following order:
+ *
+ * `[R, S, C]`
+ *
+ * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+ * `onClick` etc) and `R` is `ResponderEventPlugin`.
+ *
+ * "Deferred-Dispatched Events":
+ *
+ * - The current event plugin system will traverse the list of injected plugins,
+ *   in order, and extract events by collecting the plugin's return value of
+ *   `extractEvents()`.
+ * - These events that are returned from `extractEvents` are "deferred
+ *   dispatched events".
+ * - When returned from `extractEvents`, deferred-dispatched events contain an
+ *   "accumulation" of deferred dispatches.
+ * - These deferred dispatches are accumulated/collected before they are
+ *   returned, but processed at a later time by the `EventPluginRegistry` (hence the
+ *   name deferred).
+ *
+ * In the process of returning their deferred-dispatched events, event plugins
+ * themselves can dispatch events on-demand without returning them from
+ * `extractEvents`. Plugins might want to do this, so that they can use event
+ * dispatching as a tool that helps them decide which events should be extracted
+ * in the first place.
+ *
+ * "On-Demand-Dispatched Events":
+ *
+ * - On-demand-dispatched events are not returned from `extractEvents`.
+ * - On-demand-dispatched events are dispatched during the process of returning
+ *   the deferred-dispatched events.
+ * - They should not have side effects.
+ * - They should be avoided, and/or eventually be replaced with another
+ *   abstraction that allows event plugins to perform multiple "rounds" of event
+ *   extraction.
+ *
+ * Therefore, the sequence of event dispatches becomes:
+ *
+ * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+ * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+ * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+ * - `R`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
+ * - `S`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
+ * - `C`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
+ *
+ * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+ * on-demand dispatch returns `true` (and some other details are satisfied) the
+ * `onResponderGrant` deferred dispatched event is returned from
+ * `extractEvents`. The sequence of dispatch executions in this case
+ * will appear as follows:
+ *
+ * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+ * - `touchStartCapture`       (`EventPluginRegistry` dispatches as usual)
+ * - `touchStart`              (`EventPluginRegistry` dispatches as usual)
+ * - `responderGrant/Reject`   (`EventPluginRegistry` dispatches as usual)

+/**
+ * Summary of `DOMEventPluginSystem` event handling:
+ *
+ *  - Top-level delegation is used to trap most native browser events. This
+ *    may only occur in the main thread and is the responsibility of
+ *    ReactDOMEventListener, which is injected and can therefore support
+ *    pluggable event sources. This is the only work that occurs in the main
+ *    thread.
+ *
+ *  - We normalize and de-duplicate events to account for browser quirks. This
+ *    may be done in the worker thread.
+ *
+ *  - Forward these native events (with the associated top-level type used to
+ *    trap it) to `EventPluginRegistry`, which in turn will ask plugins if they want
+ *    to extract any synthetic events.
+ *
+ *  - The `EventPluginRegistry` will then process each event by annotating them with
+ *    "dispatches", a sequence of listeners and IDs that care about that event.
+ *
+ *  - The `EventPluginRegistry` then dispatches the events.

+   *   immediately to indicate so, either by highlighting or moving accordingly.
+   * - To be the responder means, that touches are exclusively important to that
+   *   responder view, and no other view.
+   * - While touches are still occurring, the responder lock can be transferred to
+   *   a new view, but only to increasingly "higher" views (meaning ancestors of
+   *   the current responder).
+   *
+   * Responder being granted:
+   * ------------------------
+   *
+   * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+   * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+   *   the "appropriate place".
+   * - If nothing is currently the responder, the "appropriate place" is the
+   *   initiating event's `targetID`.
+   * - If something *is* already the responder, the "appropriate place" is the
+   *   first common ancestor of the event target and the current `responderInst`.
+   * - Some negotiation happens: See the timing diagram below.
+   * - Scrolled views automatically become responder. The reasoning is that a
+   *   platform scroll view that isn't built on top of the responder system has
+   *   began scrolling, and the active responder must now be notified that the
+   *   interaction is no longer locked to it - the system has taken over.
+   *
+   * - Responder being released:
+   *   As soon as no more touches that *started* inside of descendants of the
+   *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+   *   current responder, and the responder lock is released.
+   *
+   * TODO:
+   * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+   *   determines if the responder lock should remain.
+   * - If a view shouldn't "remain" the responder, any active touches should by
+   *   default be considered "dead" and do not influence future negotiations or
+   *   bubble paths. It should be as if those touches do not exist.
+   * -- For multitouch: Usually a translate-z will choose to "remain" responder
+   *  after one out of many touches ended. For translate-y, usually the view
+   *  doesn't wish to "remain" responder after one of many touches end.
+   * - Consider building this on top of a `stopPropagation` model similar to
+   *   `W3C` events.
+   * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+   *   not `onResponderTerminationRequest` returns `true` or `false`.

+  /**
+   * A note about event ordering in the `EventPluginRegistry`.
+   *
+   * Suppose plugins are injected in the following order:
+   *
+   * `[R, S, C]`
+   *
+   * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+   * `onClick` etc) and `R` is `ResponderEventPlugin`.
+   *
+   * "Deferred-Dispatched Events":
+   *
+   * - The current event plugin system will traverse the list of injected plugins,
+   *   in order, and extract events by collecting the plugin's return value of
+   *   `extractEvents()`.
+   * - These events that are returned from `extractEvents` are "deferred
+   *   dispatched events".
+   * - When returned from `extractEvents`, deferred-dispatched events contain an
+   *   "accumulation" of deferred dispatches.
+   * - These deferred dispatches are accumulated/collected before they are
+   *   returned, but processed at a later time by the `EventPluginRegistry` (hence the
+   *   name deferred).
+   *
+   * In the process of returning their deferred-dispatched events, event plugins
+   * themselves can dispatch events on-demand without returning them from
+   * `extractEvents`. Plugins might want to do this, so that they can use event
+   * dispatching as a tool that helps them decide which events should be extracted
+   * in the first place.
+   *
+   * "On-Demand-Dispatched Events":
+   *
+   * - On-demand-dispatched events are not returned from `extractEvents`.
+   * - On-demand-dispatched events are dispatched during the process of returning
+   *   the deferred-dispatched events.
+   * - They should not have side effects.
+   * - They should be avoided, and/or eventually be replaced with another
+   *   abstraction that allows event plugins to perform multiple "rounds" of event
+   *   extraction.
+   *
+   * Therefore, the sequence of event dispatches becomes:
+   *
+   * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+   * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+   * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+   * - `R`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
+   * - `S`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
+   * - `C`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
+   *
+   * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+   * on-demand dispatch returns `true` (and some other details are satisfied) the
+   * `onResponderGrant` deferred dispatched event is returned from
+   * `extractEvents`. The sequence of dispatch executions in this case
+   * will appear as follows:
+   *
+   * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+   * - `touchStartCapture`       (`EventPluginRegistry` dispatches as usual)
+   * - `touchStart`              (`EventPluginRegistry` dispatches as usual)
+   * - `responderGrant/Reject`   (`EventPluginRegistry` dispatches as usual)

+   *
+   *  - We normalize and de-duplicate events to account for browser quirks. This
+   *    may be done in the worker thread.
+   *
+   *  - Forward these native events (with the associated top-level type used to
+   *    trap it) to `EventPluginRegistry`, which in turn will ask plugins if they want
+   *    to extract any synthetic events.
+   *
+   *  - The `EventPluginRegistry` will then process each event by annotating them with
+   *    "dispatches", a sequence of listeners and IDs that care about that event.
+   *
+   *  - The `EventPluginRegistry` then dispatches the events.

+# `react-test-renderer`
+
+This package provides an experimental React renderer that can be used to render React components to pure JavaScript objects, without depending on the DOM or a native mobile environment.
+
+Essentially, this package makes it easy to grab a snapshot of the "DOM tree" rendered by a React DOM or React Native component without using a browser or jsdom.
+
+Documentation:
+
+[https://reactjs.org/docs/test-renderer.html](https://reactjs.org/docs/test-renderer.html)
+
+Usage:
+
+```jsx
+const ReactTestRenderer = require('react-test-renderer');
+
+const renderer = ReactTestRenderer.create(
+  <Link page="https://www.facebook.com/">Facebook</Link>
+);
+
+console.log(renderer.toJSON());
+// { type: 'a',
+//   props: { href: 'https://www.facebook.com/' },
+//   children: [ 'Facebook' ] }
+```
+
+You can also use Jest's snapshot testing feature to automatically save a copy of the JSON tree to a file and check in your tests that it hasn't changed: https://facebook.github.io/jest/blog/2016/07/27/jest-14.html.

+# `react`
+
+React is a JavaScript library for creating user interfaces.
+
+The `react` package contains only the functionality necessary to define React components. It is typically used together with a React renderer like `react-dom` for the web, or `react-native` for the native environments.
+
+**Note:** by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the [production build](https://reactjs.org/docs/optimizing-performance.html#use-the-production-build) when deploying your application.
+
+## Example Usage
+
+```js
+var React = require('react');
+```
