 [React Native][react-native-url] components and APIs for the Web.
 
+Browser support: Chrome, Firefox, Safari >= 7, IE 10, Edge.
+
+## Overview
+
+"React Native for Web" is a project to bring React Native's building blocks and
+touch handling to the Web.
+
+React Native provides a foundational layer to support interoperable,
+zero-configuration React component development. This is missing from React's
+web ecosystem where OSS components rely on inline styles (usually without
+vendor prefixes), or require build tool configuration. This project allows
+components built upon React Native to be run on the Web, and it manages all
+component styling out-of-the-box.
+
+For example, the [`View`](docs/apis/View.md) component makes it easy to build
+cross-browser layouts with flexbox, such as stacked and nested boxes with
+margin and padding. And the [`StyleSheet`](docs/guides/style.md) API converts
+styles defined in JavaScript into "Atomic CSS".

+/**
+ * `PanResponder` reconciles several touches into a single gesture. It makes
+ * single-touch gestures resilient to extra touches, and can be used to
+ * recognize simple multi-touch gestures.
+ *
+ * It provides a predictable wrapper of the responder handlers provided by the
+ * [gesture responder system](docs/gesture-responder-system.html).
+ * For each handler, it provides a new `gestureState` object alongside the
+ * native event object:
+ *
+ * ```
+ * onPanResponderMove: (event, gestureState) => {}
+ * ```
+ *
+ * A native event is a synthetic touch event with the following form:
+ *
+ *  - `nativeEvent`
+ *      + `changedTouches` - Array of all touch events that have changed since the last event
+ *      + `identifier` - The ID of the touch
+ *      + `locationX` - The X position of the touch, relative to the element
+ *      + `locationY` - The Y position of the touch, relative to the element
+ *      + `pageX` - The X position of the touch, relative to the root element
+ *      + `pageY` - The Y position of the touch, relative to the root element
+ *      + `target` - The node id of the element receiving the touch event
+ *      + `timestamp` - A time identifier for the touch, useful for velocity calculation
+ *      + `touches` - Array of all current touches on the screen
+ *
+ * A `gestureState` object has the following:
+ *
+ *  - `stateID` - ID of the gestureState- persisted as long as there at least
+ *     one touch on screen
+ *  - `moveX` - the latest screen coordinates of the recently-moved touch
+ *  - `moveY` - the latest screen coordinates of the recently-moved touch
+ *  - `x0` - the screen coordinates of the responder grant
+ *  - `y0` - the screen coordinates of the responder grant
+ *  - `dx` - accumulated distance of the gesture since the touch started
+ *  - `dy` - accumulated distance of the gesture since the touch started
+ *  - `vx` - current velocity of the gesture
+ *  - `vy` - current velocity of the gesture
+ *  - `numberActiveTouches` - Number of touches currently on screen
+ *
+ * ### Basic Usage

+ *         // The most recent move distance is gestureState.move{X,Y}
+ *
+ *         // The accumulated gesture distance since becoming responder is
+ *         // gestureState.d{x,y}
+ *       },
+ *       onPanResponderTerminationRequest: (evt, gestureState) => true,
+ *       onPanResponderRelease: (evt, gestureState) => {
+ *         // The user has released all touches while this view is the
+ *         // responder. This typically means a gesture has succeeded
+ *       },
+ *       onPanResponderTerminate: (evt, gestureState) => {
+ *         // Another component has become the responder, so this gesture
+ *         // should be cancelled
+ *       },
+ *       onShouldBlockNativeResponder: (evt, gestureState) => {
+ *         // Returns whether this component should block native components from becoming the JS
+ *         // responder. Returns true by default. Is currently only supported on android.
+ *         return true;
+ *       },
+ *     });
+ *   },
+ *
+ *   render: function() {
+ *     return (
+ *       <View {...this._panResponder.panHandlers} />
+ *     );
+ *   },
+ *

+   *
+   * Gesture that calculates cumulative movement over time in a way that just
+   * "does the right thing" for multiple touches. The "right thing" is very
+   * nuanced. When moving two touches in opposite directions, the cumulative
+   * distance is zero in each dimension. When two touches move in parallel five
+   * pixels in the same direction, the cumulative distance is five, not ten. If
+   * two touches start, one moves five in a direction, then stops and the other
+   * touch moves fives in the same direction, the cumulative distance is ten.
+   *
+   * This logic requires a kind of processing of time "clusters" of touch events
+   * so that two touch moves that essentially occur in parallel but move every
+   * other frame respectively, are considered part of the same movement.
+   *
+   * Explanation of some of the non-obvious fields:
+   *
+   * - moveX/moveY: If no move event has been observed, then `(moveX, moveY)` is
+   *   invalid. If a move event has been observed, `(moveX, moveY)` is the
+   *   centroid of the most recently moved "cluster" of active touches.
+   *   (Currently all move have the same timeStamp, but later we should add some
+   *   threshold for what is considered to be "moving"). If a palm is
+   *   accidentally counted as a touch, but a finger is moving greatly, the palm
+   *   will move slightly, but we only want to count the single moving touch.
+   * - x0/y0: Centroid location (non-cumulative) at the time of becoming
+   *   responder.
+   * - dx/dy: Cumulative touch distance - not the same thing as sum of each touch
+   *   distance. Accounts for touch moves that are clustered together in time,
+   *   moving the same direction. Only valid when currently responder (otherwise,
+   *   it only represents the drag distance below the threshold).
+   * - vx/vy: Velocity.

+   * touches, and calculate how the centroid has changed just for those

+   * to (at least) handle the case where the user is moving three fingers, and

+   *
+   * This is very different than taking all of the recently moved touches and

+   * changes* in the centroid of recently moved touches.
+   *
+   * There is also some nuance with how we handle multiple moved touches in a

+   * individual events, multiple touches generate two 'move' events, each of
+   * them triggering `onResponderMove`. But with the way `PanResponder` works,
+   * all of the gesture inference is performed on the first dispatch, since it
+   * looks at all of the touches (even the ones for which there hasn't been a
+   * native dispatch yet). Therefore, `PanResponder` does not call
+   * `onResponderMove` passed the first dispatch. This diverges from the

+ * `Touchable`: Taps done right.
+ *
+ * You hook your `ResponderEventPlugin` events into `Touchable`. `Touchable`
+ * will measure time/geometry and tells you when to give feedback to the user.
+ *
+ * ====================== Touchable Tutorial ===============================
+ * The `Touchable` mixin helps you handle the "press" interaction. It analyzes
+ * the geometry of elements, and observes when another responder (scroll view
+ * etc) has stolen the touch lock. It notifies your component when it should
+ * give feedback to the user. (bouncing/highlighting/unhighlighting).
+ *
+ * - When a touch was activated (typically you highlight)
+ * - When a touch was deactivated (typically you unhighlight)
+ * - When a touch was "pressed" - a touch ended while still within the geometry
+ *   of the element, and no other element (like scroller) has "stolen" touch
+ *   lock ("responder") (Typically you bounce the element).
+ *
+ * A good tap interaction isn't as simple as you might think. There should be a
+ * slight delay before showing a highlight when starting a touch. If a
+ * subsequent touch move exceeds the boundary of the element, it should
+ * unhighlight, but if that same touch is brought back within the boundary, it
+ * should rehighlight again. A touch can move in and out of that boundary
+ * several times, each time toggling highlighting, but a "press" is only
+ * triggered if that touch ends while within the element's boundary and no
+ * scroller (or anything else) has stolen the lock on touches.
+ *
+ * To create a new type of component that handles interaction using the
+ * `Touchable` mixin, do the following:
+ *
+ * - Initialize the `Touchable` state.
+ *
+ *   getInitialState: function() {
+ *     return merge(this.touchableGetInitialState(), yourComponentState);
+ *   }
+ *
+ * - Choose the rendered component who's touches should start the interactive
+ *   sequence. On that rendered node, forward all `Touchable` responder
+ *   handlers. You can choose any rendered node you like. Choose a node whose
+ *   hit target you'd like to instigate the interaction sequence:
+ *
+ *   // In render function:
+ *   return (
+ *     <View
+ *       onStartShouldSetResponder={this.touchableHandleStartShouldSetResponder}
+ *       onResponderTerminationRequest={this.touchableHandleResponderTerminationRequest}
+ *       onResponderGrant={this.touchableHandleResponderGrant}
+ *       onResponderMove={this.touchableHandleResponderMove}
+ *       onResponderRelease={this.touchableHandleResponderRelease}
+ *       onResponderTerminate={this.touchableHandleResponderTerminate}>
+ *       <View>
+ *         Even though the hit detection/interactions are triggered by the
+ *         wrapping (typically larger) node, we usually end up implementing
+ *         custom logic that highlights this inner one.
+ *       </View>
+ *     </View>
+ *   );
+ *
+ * - You may set up your own handlers for each of these events, so long as you
+ *   also invoke the `touchable*` handlers inside of your custom handler.
+ *
+ * - Implement the handlers on your component class in order to provide
+ *   feedback to the user. See documentation for each of these class methods
+ *   that you should implement.
+ *
+ *   touchableHandlePress: function() {
+ *      this.performBounceAnimation();  // or whatever you want to do.
+ *   },
+ *   touchableHandleActivePressIn: function() {
+ *     this.beginHighlighting(...);  // Whatever you like to convey activation
+ *   },
+ *   touchableHandleActivePressOut: function() {
+ *     this.endHighlighting(...);  // Whatever you like to convey deactivation
+ *   },
+ *
+ * - There are more advanced methods you can implement (see documentation below):
+ *   touchableGetHighlightDelayMS: function() {
+ *     return 20;
+ *   }
+ *   // In practice, *always* use a predeclared constant (conserve memory).

+ * ========== Geometry =========
+ * `Touchable` only assumes that there exists a `HitRect` node. The `PressRect`
+ * is an abstract box that is extended beyond the `HitRect`.
+ *
+ *  +--------------------------+
+ *  |                          | - "Start" events in `HitRect` cause `HitRect`
+ *  |  +--------------------+  |   to become the responder.
+ *  |  |  +--------------+  |  | - `HitRect` is typically expanded around
+ *  |  |  |              |  |  |   the `VisualRect`, but shifted downward.
+ *  |  |  |  VisualRect  |  |  | - After pressing down, after some delay,
+ *  |  |  |              |  |  |   and before letting up, the Visual React
+ *  |  |  +--------------+  |  |   will become "active". This makes it eligible
+ *  |  |     HitRect        |  |   for being highlighted (so long as the
+ *  |  +--------------------+  |   press remains in the `PressRect`).
+ *  |        PressRect     o   |
+ *  +----------------------|---+
+ *           Out Region    |
+ *                         +-----+ This gap between the `HitRect` and
+ *                                 `PressRect` allows a touch to move far away
+ *                                 from the original hit rect, and remain
+ *                                 highlighted, and eligible for a "Press".
+ *                                 Customize this via
+ *                                 `touchableGetPressRectOffset()`.

+ * backgroundColor of the wrapped view isn't explicitly set to an opaque color.

+ * ```
