|

|
||||
[React Native][react-native-url] components and APIs for the Web.
|
||||
"React Native for Web" brings the platform-agnostic Components and APIs of
|
||||
[React Native][react-native-url] to the Web.
|
||||
|
||||
Browser support: Chrome, Firefox, Safari >= 7, IE 10, Edge.
|
||||
* **High-quality user interfaces**: React Native for Web makes it easy to
|
||||
create [fast](https://github.com/necolas/react-native-web/blob/master/packages/benchmarks/README.md),
|
||||
adaptive web UIs in JavaScript. It provides native-like interactions, support
|
||||
for multiple input modes (touch, mouse, keyboard), optimized vendor-prefixed
|
||||
styles, built-in support for RTL layout, built-in accessibility, and integrates
|
||||
with React Dev Tools.

|
||||
* **Write once, render anywhere**: React Native for Web interoperates with
|
||||
existing React DOM components and is compatible with the majority of the
|
||||
React Native API. You can develop new components for native and web without
|
||||
rewriting existing code. React Native for Web can also render to HTML and
|
||||
critical CSS on the server using Node.js.
|
||||
|
||||
## Overview
|
||||
Who is using React Native for Web? [Twitter](https://mobile.twitter.com),
|
||||
[Major League Soccer](https://matchcenter.mlssoccer.com),
|
||||
[Flipkart](https://www.flipkart.com/), Playstation, Uber, [The
|
||||
Times](https://github.com/newsuk/times-components), [React Native's
|
||||
documentation](http://facebook.github.io/react-native/).
|
||||
|
||||
"React Native for Web" is a project to bring React Native's building blocks and
|
||||
touch handling to the Web.
|
||||
|
||||
Browse the [UI Explorer](https://necolas.github.io/react-native-web/storybook/)
|
||||
to see React Native examples running on Web. Or remix the [React Native for
|
||||
Web: Playground](https://glitch.com/edit/#!/react-native-web-playground) on
|
||||
Glitch.
|
||||
Browser support: Chrome, Firefox, Edge, Safari 7+, IE 10+.
|
||||
|
||||
## Quick start
|
||||
|
||||
NOTE: React Native for Web supports React/ReactDOM 15.4, 15.5, or 15.6.
|
||||
|
||||
Install in your existing app using `yarn` or `npm`:
|
||||
|
||||
```
|
||||
yarn add react@15.6 react-dom@15.6 react-native-web
|
||||
```
|
||||
|
||||
Then read the [Getting Started](docs/guides/getting-started.md) guide.
|
||||
The easiest way to get started with React Native for Web is to use this
|
||||
[CodeSandbox](https://codesandbox.io/s/q4qymyp2l6) template (or
|
||||
[Glitch](https://glitch.com/edit/#!/react-native)). You don’t need to install
|
||||
anything to try it out.
|
||||
|
||||
## Documentation
|
||||
|
||||
The [UI Explorer](https://necolas.github.io/react-native-web/storybook/)
|
||||
interactively documents all the APIs and Components.
|
||||
You can find the React Native for Web API documentation [on the

## Examples
|
||||
|
||||
## Example code
|
||||
There are several examples [on the website][website-url] and in the [website's
|
||||
source code](https://github.com/necolas/react-native-web/blob/master/website).
|
||||
Here is an example to get you started:
|
||||
|
||||
```js
|
||||
import React from 'react'
|
||||
import { AppRegistry, Image, StyleSheet, Text, View } from 'react-native'
|
||||
import React from 'react';
|
||||
import { AppRegistry, StyleSheet, Text, View } from 'react-native';
|
||||
|
||||
// Components
|
||||
const Card = ({ children }) => <View style={styles.card}>{children}</View>
|
||||
const Title = ({ children }) => <Text style={styles.title}>{children}</Text>
|
||||
const Photo = ({ uri }) => <Image source={{ uri }} style={styles.image} />
|
||||
const App = () => (
|
||||
<Card>
|
||||
<Title>App Card</Title>
|
||||
<Photo uri="/some-photo.jpg" />
|
||||
</Card>
|
||||
)
|
||||
|
||||
// Styles
|
||||
const styles = StyleSheet.create({
|
||||
card: {
|
||||
flexGrow: 1,
|
||||
justifyContent: 'center'
|
||||
},
|
||||
title: {
|
||||
fontSize: '1.25rem',
|
||||
fontWeight: 'bold'
|
||||
},
|
||||
image: {
|
||||
height: 40,
|
||||
marginVertical: 10,
|
||||
width: 40
|
||||
class App extends React.Component {
|
||||
render() {
|
||||
return (
|
||||
<View style={styles.box}>
|
||||
<Text style={styles.text}>Hello, world!</Text>
|
||||
</View>
|
||||
);
|
||||
}
|
||||
})
|
||||
}
|
||||
|
||||
// App registration and rendering
|
||||
AppRegistry.registerComponent('MyApp', () => App)
|
||||
AppRegistry.runApplication('MyApp', { rootTag: document.getElementById('react-root') })
|
||||
const styles = StyleSheet.create({
|
||||
box: { padding: 10 },
|
||||
text: { fontWeight: 'bold' }
|
||||
});
|
||||
|
||||
AppRegistry.registerComponent('App', () => App);
|
||||
AppRegistry.runApplication('App', { rootTag: document.getElementById('react-root') });
|
||||
```
|
||||
|
||||
## Related projects
|
||||
This example will render the `App` into a container on the page.
|
||||
|
||||
* [react-primitives](https://github.com/lelandrichardson/react-primitives/)
|
||||
* [react-sketchapp](https://github.com/airbnb/react-sketchapp)
|
||||
* [reactxp](https://github.com/microsoft/reactxp)
|
||||
* [react-native-web-player](https://github.com/dabbott/react-native-web-player)
|
||||
You'll notice that there is no reference to `react-dom`; the `App` component is
|
||||
defined using the platform-agnostic APIs and Components introduced by React
|
||||
Native. This allows the app to be rendered to web and native platforms.

# Performance
|
||||
|
||||
To run these benchmarks:
|
||||
|
||||
```
|
||||
npm run build:performance
|
||||
open ./performance/index.html
|
||||
```
|
||||
|
||||
Append `?fastest` to the URL to include the fastest "other libraries", and
|
||||
`?all` to include all the "other libraries".
|
||||
|
||||
## Notes
|
||||
|
||||
The components used in the render benchmarks are simple enough to be
|
||||
implemented by multiple UI or style libraries. The implementations are not
|
||||
equivalent in functionality. For example, React Native for Web's stylesheet is
|
||||
unique in that it also converts React Native styles to DOM styles, has
|
||||
deterministic resolution, and supports RTL layout.
|
||||
|
||||
`react-native-web/stylesheet` is a comparative baseline that implements a
|
||||
simple `View` without much of React Native's functionality.
|
||||
|
||||
## Benchmark results

||||

|
||||
| `radium@0.19.1` | `518.48` `±69.74` | `1058.85` `±120.85` |
|
||||
|
||||
These results indicate that styled render performance is not a significant
|
||||
differentiating factor between `aphrodite`, `css-modules`, `react-native-web`,
|
||||
and `styletron`.

# AppRegistry
|
||||
|
||||
`AppRegistry` is the control point for registering, running, prerendering, and
|
||||
unmounting all apps. App root components should register themselves with
|
||||
`AppRegistry.registerComponent`. Apps can be run by invoking
|
||||
`AppRegistry.runApplication` (see the [getting started guide](../guides/getting-started.md) for more details).
|
||||
|
||||
To "stop" an application when a view should be destroyed, call
|
||||
`AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was passed
|
||||
into `runApplication`. These should always be used as a pair.
|
||||
|
||||
## Methods
|
||||
|
||||
(web) static **getApplication**(appKey:string, appParameters: object)
|
||||
|
||||
Returns the given application element. Use this for server-side rendering.
|
||||
Return object is of type `{ element: ReactElement; stylesheets: [ ReactElement ] }`.
|
||||
|
||||
static **registerConfig**(config: Array<AppConfig>)
|
||||
|
||||
Registry multiple applications. `AppConfig` is of type `{ appKey: string;
|
||||
component: ComponentProvider; run?: Function }`.
|
||||
|
||||
static **registerComponent**(appKey: string, getComponentFunc: ComponentProvider)
|
||||
|
||||
Register a component provider under the given `appKey`.
|
||||
|
||||
static **registerRunnable**(appKey: string, run: Function)
|
||||
|
||||
Register a custom render function for an application. The function will receive
|
||||
the `appParameters` passed to `runApplication`.
|
||||
|
||||
static **getAppKeys**()
|
||||
|
||||
Returns all registered app keys.
|
||||
|
||||
static **runApplication**(appKey: string, appParameters?: object)
|
||||
|
||||
Runs the application that was registered under `appKey`. The `appParameters`
|
||||
must include the `rootTag` into which the application is rendered, and
|
||||
optionally any `initialProps`.
|
||||
|
||||
On web, if the `rootTag` is a sub-section of your application it should be
|
||||
styled as `position:relative` and given an explicit height.
|
||||
|
||||
static **unmountApplicationComponentAtRootTag**(rootTag: HTMLElement)
|
||||
|
||||
To "stop" an application when a view should be destroyed, call
|
||||
`AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was passed
|
||||
into `runApplication`
|
||||
|
||||
## Example
|
||||
|
||||
```js
|
||||
AppRegistry.registerComponent('MyApp', () => AppComponent)
|
||||
AppRegistry.runApplication('MyApp', {
|
||||
initialProps: {},
|
||||
rootTag: document.getElementById('react-root')

## AppState
|
||||
|
||||
`AppState` can tell you if the app is in the foreground or background, and
|
||||
notify you when the state changes.
|
||||
|
||||
States
|
||||
|
||||
* `active` - The app is running in the foreground
|
||||
* `background` - The app is running in the background (i.e., the user has not focused the app's tab).
|
||||
|
||||
## Properties
|
||||
|
||||
static **currentState**
|
||||
|
||||
Returns the current state of the app: `active` or `background`.
|
||||
|
||||
## Methods
|
||||
|
||||
static **addEventListener**(type: string, handler: Function)
|
||||
|
||||
Add a handler to `AppState` changes by listening to the `change` event type and
|
||||
providing the `handler`. The handler is called with the app state value.
|
||||
|
||||
static **removeEventListener**(type: string, handler: Function)
|
||||
|
||||
Remove a handler by passing the change event `type` and the `handler`.
|
||||
|
||||
## Examples
|
||||
|
||||
To see the current state, you can check `AppState.currentState`, which will be
|
||||
kept up-to-date. This example will only ever appear to say "Current state is:
|
||||
active" because the app is only visible to the user when in the `active` state,
|
||||
and the null state will happen only momentarily.
|
||||
|
||||
```js
|
||||
class Example extends React.Component {
|
||||
constructor(props) {
|
||||
super(props)
|
||||
this.state = { currentAppState: AppState.currentState }
|
||||
}

||||
componentDidMount() {
|
||||
AppState.addEventListener('change', this._handleAppStateChange);

||||
componentWillUnmount() {
|
||||
AppState.removeEventListener('change', this._handleAppStateChange);

# AsyncStorage
|
||||
|
||||
`AsyncStorage` is a simple, asynchronous, persistent, key-value storage system
|
||||
that is global to the domain. It's a facade over, and should be used instead of
|
||||
`window.localStorage` to provide an asynchronous API and multi functions. Each
|
||||
method returns a `Promise` object.
|
||||
|
||||
It is recommended that you use an abstraction on top of `AsyncStorage` instead
|
||||
of `AsyncStorage` directly for anything more than light usage since it operates
|
||||
globally.
|
||||
|
||||
The batched functions are useful for executing a lot of operations at once,
|
||||
allowing for optimizations to provide the convenience of a single promise after
|
||||
all operations are complete.
|
||||
|
||||
## Methods
|
||||
|
||||
static **clear**()
|
||||
|
||||
Erases all AsyncStorage. You probably don't want to call this - use
|
||||
`removeItem` or `multiRemove` to clear only your own keys instead. Returns a
|
||||
Promise object.
|
||||
|
||||
static **getAllKeys**()
|
||||
|
||||
Gets all known keys. Returns a Promise object.
|
||||
|
||||
static **getItem**(key: string)
|
||||
|
||||
Fetches the value of the given key. Returns a Promise object.
|
||||
|
||||
static **mergeItem**(key: string, value: string)
|
||||
|
||||
Merges existing value with input value, assuming they are stringified JSON.
|
||||
Returns a Promise object.
|
||||
|
||||
static **multiGet**(keys: Array<string>)
|
||||
|
||||
`multiGet` results in an array of key-value pair arrays that matches the input
|
||||
format of `multiSet`. Returns a Promise object.
|
||||
|
||||
```js
|
||||
multiGet(['k1', 'k2']) -> [['k1', 'val1'], ['k2', 'val2']]
|
||||
```
|
||||
|
||||
static **multiMerge**(keyValuePairs: Array<Array<string>>)
|
||||
|
||||
multiMerge takes an array of key-value array pairs that match the output of
|
||||
`multiGet`. It merges existing values with input values, assuming they are
|
||||
stringified JSON. Returns a Promise object.
|
||||
|
||||
static **multiRemove**(keys: Array<string>)
|
||||
|
||||
Delete all the keys in the keys array. Returns a Promise object.
|
||||
|
||||
static **multiSet**(keyValuePairs: Array<Array<string>>)
|
||||
|
||||
`multiSet` takes an array of key-value array pairs that match the output of
|
||||
`multiGet`. Returns a Promise object.
|
||||
|
||||
```js
|
||||
multiSet([['k1', 'val1'], ['k2', 'val2']]);
|
||||
```
|
||||
|
||||
static **removeItem**(key: string)
|
||||
|
||||
Removes the value of the given key. Returns a Promise object.
|
||||
|
||||
static **setItem**(key: string, value: string)
|
||||
|
||||
Sets the value of the given key. Returns a Promise object.

## Methods

||||

|
||||
|
||||
Copies a string to the clipboard. On web, some browsers may not support copying
|
||||
to the clipboard, therefore, this function returns a boolean to indicate if the
|
||||
copy was successful.

|

Note: dimensions may change (e.g due to device rotation) so any rendering logic

every render, rather than caching the value.

# NetInfo
|
||||
|
||||
`NetInfo` asynchronously determines the online/offline status of the
|
||||
application.
|
||||
|
||||
Connection types:
|
||||
|
||||
* `bluetooth` - The user agent is using a Bluetooth connection.
|
||||
* `cellular` - The user agent is using a cellular connection (e.g., EDGE, HSPA, LTE, etc.).
|
||||
* `ethernet` - The user agent is using an Ethernet connection.
|
||||
* `mixed` - The user agent is using multiple connection types.
|
||||
* `none` - The user agent will not contact the network (offline).
|
||||
* `other` - The user agent is using a connection type that is not one of enumerated connection types.
|
||||
* `unknown` - The user agent has established a network connection, but is unable to determine what is the underlying connection technology.
|
||||
* `wifi` - The user agent is using a Wi-Fi connection.
|
||||
* `wimax` - The user agent is using a WiMAX connection.
|
||||
|
||||
## Methods
|
||||
|
||||
Note that support for retrieving the connection type depends upon browswer
|
||||
support (and is limited to mobile browsers). It will default to `unknown` when
|
||||
support is missing.

# PixelRatio
|
||||
|
||||
`PixelRatio` gives access to the device pixel density.
|
||||
|
||||
## Methods
|
||||
|
||||
static **get**()
|
||||
|
||||
Returns the device pixel density. Some examples:
|
||||
|
||||
* PixelRatio.get() === 1
|
||||
* mdpi Android devices (160 dpi)
|
||||
* PixelRatio.get() === 1.5
|
||||
* hdpi Android devices (240 dpi)
|
||||
* PixelRatio.get() === 2
|
||||
* iPhone 4, 4S
|
||||
* iPhone 5, 5c, 5s
|
||||
* iPhone 6
|
||||
* xhdpi Android devices (320 dpi)
|
||||
* PixelRatio.get() === 3
|
||||
* iPhone 6 plus
|
||||
* xxhdpi Android devices (480 dpi)
|
||||
* PixelRatio.get() === 3.5
|
||||
* Nexus 6
|
||||
|
||||
static **getPixelSizeForLayoutSize**(layoutSize: number)
|
||||
|
||||
Converts a layout size (dp) to pixel size (px). Guaranteed to return an integer
|
||||
number.
|
||||
|
||||
static **roundToNearestPixel**(layoutSize: number)
|
||||
|
||||
Rounds a layout size (dp) to the nearest layout size that corresponds to an
|
||||
integer number of pixels. For example, on a device with a PixelRatio of 3,
|
||||
`PixelRatio.roundToNearestPixel(8.4)` = `8.33`, which corresponds to exactly
|
||||
`(8.33 * 3)` = `25` pixels.
|
||||
|
||||
## Examples
|
||||
|
||||
Fetching a correctly sized image. You should get a higher resolution image if
|
||||
you are on a high pixel density device. A good rule of thumb is to multiply the
|
||||
size of the image you display by the pixel ratio.
|
||||
|
||||
```js
|
||||
const image = getImage({
|
||||
width: PixelRatio.getPixelSizeForLayoutSize(200),

# Platform
|
||||
|
||||
Detect what is the platform in which the app is running. This piece of
|
||||
functionality can be useful when only small parts of a component are platform
|
||||
specific.
|
||||
|
||||
## Properties
|
||||
|
||||
**OS**: string
|
||||
|
||||
`Platform.OS` will be `web` when running in a Web browser.
|
||||
|
||||
```js
|
||||
import { Platform } from 'react-native';
|
||||
|
||||
const styles = StyleSheet.create({
|
||||
height: (Platform.OS === 'web') ? 200 : 100,
|
||||
});
|
||||
```
|
||||
|
||||
## Methods
|
||||
|
||||
**select**(object): any
|
||||
|
||||
`Platform.select` takes an object containing `Platform.OS` as keys and returns
|
||||
the value for the platform you are currently running on.
|
||||
|
||||
```js
|
||||
import { Platform } from 'react-native';

# StyleSheet
|
||||
|
||||
The `StyleSheet` abstraction converts predefined styles to (vendor-prefixed)
|
||||
CSS without requiring a compile-time step. Styles that cannot be resolved
|
||||
outside of the render loop (e.g., dynamic positioning) are usually applied as
|
||||
inline styles. Read more about [how to style your
|
||||
application](../guides/style.md).
|
||||
|
||||
## Methods
|
||||
|
||||
**create**(obj: {[key: string]: any})
|
||||
|
||||
Each key of the object passed to `create` must define a style object.
|
||||
|
||||
**flatten**: function
|
||||
|
||||
Flattens an array of styles into a single style object.
|
||||
|
||||
(web) **getStyleSheets**: function
|
||||
|
||||
Returns an array of stylesheets (`{ id, textContent }`). Useful for
|
||||
compile-time or server-side rendering.
|
||||
|
||||
## Properties
|
||||
|
||||
**absoluteFill**: number
|
||||
|
||||
A very common pattern is to create overlays with position absolute and zero positioning,
|
||||
so `absoluteFill` can be used for convenience and to reduce duplication of these repeated
|
||||
styles.
|
||||
|
||||
```js
|
||||
<View style={StyleSheet.absoluteFill} />
|
||||
```
|
||||
|
||||
**absoluteFillObject**: object
|
||||
|
||||
Sometimes you may want `absoluteFill` but with a couple tweaks - `absoluteFillObject` can be
|
||||
used to create a customized entry in a `StyleSheet`, e.g.:
|
||||
|
||||
```js
|
||||
const styles = StyleSheet.create({
|
||||
wrapper: {
|
||||
...StyleSheet.absoluteFillObject,
|
||||
backgroundColor: 'transparent',
|
||||
top: 10
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
**hairlineWidth**: number
|
||||
|
||||
## Example
|
||||
|
||||
```js
|
||||
<View style={styles.container}>
|
||||
<Text
|
||||
children={'Title text'}
|
||||
style={[
|
||||
styles.title,
|
||||
this.props.isActive && styles.activeTitle

# Vibration
|
||||
|
||||
Vibration is described as a pattern of on-off pulses, which may be of varying
|
||||
lengths. The pattern may consist of either a single integer, describing the
|
||||
number of milliseconds to vibrate, or an array of integers describing a pattern
|
||||
of vibrations and pauses. Vibration is controlled with a single method:
|
||||
`Vibration.vibrate()`.
|
||||
|
||||
The vibration is asynchronous so this method will return immediately. There
|
||||
will be no effect on devices that do not support vibration.
|
||||
|
||||
## Methods
|
||||
|
||||
static **cancel**()
|
||||
|
||||
Stop the vibration.
|
||||
|
||||
static **vibrate**(pattern)
|
||||
|
||||
Start the vibration pattern.
|
||||
|
||||
## Examples
|
||||
|
||||
Vibrate once for 200ms:
|
||||
|
||||
```js
|
||||
Vibration.vibrate(200);
|
||||
Vibration.vibrate([200]);
|
||||
```
|
||||
|
||||
Vibrate for 200ms, pause for 100ms, vibrate for 200ms:

(In order to retrieve the image dimensions, the image may first need to be
|
||||
loaded or downloaded, after which it will be cached. This means that in
|
||||
principle you could use this method to preload images, however it is not

not fully load/download the image data.)

# ScrollView
|
||||
|
||||
A scrollable `View` that provides itegration with the touch-locking "responder"
|
||||
system. `ScrollView`'s must have a bounded height: either set the height of the
|
||||
view directly (discouraged) or make sure all parent views have bounded height
|
||||
(e.g., transfer `{ flex: 1}` down the view stack).
|
||||
|
||||
## Props
|
||||
|
||||
[...View props](./View.md)
|
||||
|
||||
**contentContainerStyle**: ?style
|
||||
|
||||
These styles will be applied to the scroll view content container which wraps
|
||||
all of the child views.
|
||||
|
||||
**horizontal**: ?boolean = false
|
||||
|
||||
When `true`, the scroll view's children are arranged horizontally in a row
|
||||
instead of vertically in a column.
|
||||
|
||||
**keyboardDismissMode**: ?enum('none', 'on-drag') = 'none'
|
||||
|
||||
Determines whether the keyboard gets dismissed in response to a scroll drag.
|
||||
|
||||
* `none` (the default), drags do not dismiss the keyboard.
|
||||
* `on-drag`, the keyboard is dismissed when a drag begins.
|
||||
* `interactive` (not supported on web; same as `none`)
|
||||
|
||||
**onContentSizeChange**: ?function
|
||||
|
||||
Called when scrollable content view of the `ScrollView` changes. It's
|
||||
implemented using the `onLayout` handler attached to the content container
|
||||
which this `ScrollView` renders.
|
||||
|
||||
**onScroll**: ?function
|
||||
|
||||
Fires at most once per frame during scrolling. The frequency of the events can
|
||||
be contolled using the `scrollEventThrottle` prop.
|
||||
|
||||
Invoked on scroll with the following event:
|
||||
|
||||
```js
|
||||
{
|
||||
nativeEvent: {
|
||||
contentOffset: { x, y },
|
||||
contentSize: { height, width },
|
||||
layoutMeasurement: { height, width }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**refreshControl**: ?element
|
||||
|
||||
TODO
|
||||
|
||||
A [RefreshControl](../RefreshControl) component, used to provide
|
||||
pull-to-refresh functionality for the `ScrollView`.
|
||||
|
||||
**scrollEnabled**: ?boolean = true
|
||||
|
||||
When false, the content does not scroll.
|
||||
|
||||
**scrollEventThrottle**: ?number = 0
|
||||
|
||||
This controls how often the scroll event will be fired while scrolling (as a
|
||||
time interval in ms). A lower number yields better accuracy for code that is
|
||||
tracking the scroll position, but can lead to scroll performance problems. The
|
||||
default value is `0`, which means the scroll event will be sent only once each
|
||||
time the view is scrolled.
|
||||
|
||||
## Instance methods
|
||||
|
||||
**getInnerViewNode()**: any
|
||||
|
||||
Returns a reference to the underlying content container DOM node within the `ScrollView`.
|
||||
|
||||
**getScrollableNode()**: any
|
||||
|
||||
Returns a reference to the underlying scrollable DOM node.
|
||||
|
||||
**getScrollResponder()**: Component
|
||||
|
||||
Returns a reference to the underlying scroll responder, which supports
|
||||
operations like `scrollTo`. All `ScrollView`-like components should implement
|
||||
this method so that they can be composed while providing access to the
|
||||
underlying scroll responder's methods.
|
||||
|
||||
**scrollTo(options: { x: number = 0; y: number = 0; animated: boolean = true })**
|
||||
|
||||
Scrolls to a given `x`, `y` offset (animation is not currently supported).
|
||||
|
||||

# Text
|
||||
|
||||
`Text` is component for displaying text. It supports style, basic touch
|
||||
handling, and inherits typographic styles from ancestor elements.
|
||||
|
||||
The `Text` is unique relative to layout: child elements use text layout
|
||||
(`inline`) rather than flexbox layout. This means that elements inside of a
|
||||
`Text` are not rectangles, as they wrap when reaching the edge of their
|
||||
container.
|
||||
|
||||
Unsupported React Native props:
|
||||
`allowFontScaling` (ios),
|
||||
`suppressHighlighting` (ios)
|
||||
|
||||
## Props
|
||||
|
||||
NOTE: `Text` will transfer all other props to the rendered HTML element.
|
||||
|
||||
(web) **accessibilityLabel**: ?string
|
||||
|
||||
Overrides the text that's read by a screen reader when the user interacts
|
||||
with the element. (This is implemented using `aria-label`.)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility) for more information.
|
||||
|
||||
(web) **accessibilityRole**: ?oneOf(roles)
|
||||
|
||||
Allows assistive technologies to present and support interaction with the view
|
||||
in a manner that is consistent with user expectations for similar views of that
|
||||
type. For example, marking a touchable view with an `accessibilityRole` of
|
||||
`button`. (This is implemented using [ARIA roles](http://www.w3.org/TR/wai-aria/roles#role_definitions)).
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility) for more information.
|
||||
|
||||
**accessible**: ?boolean
|
||||
|
||||
When `true`, indicates that the view is an accessibility element (i.e.,
|
||||
focusable) and groups its child content. By default, all the touchable elements
|
||||
and elements with `accessibilityRole` of `button` and `link` are accessible.
|
||||
(This is implemented using `tabindex`.)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility) for more information.
|
||||
|
||||
**children**: ?any
|
||||
|
||||
Child content.
|
||||
|
||||
**importantForAccessibility**: ?enum('auto', 'no-hide-descendants', 'yes')
|
||||
|
||||
A value of `no` will remove the element from the tab flow.
|
||||
|
||||
A value of `no-hide-descendants` will hide the element and its children from
|
||||
assistive technologies. (This is implemented using `aria-hidden`.)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility) for more information.
|
||||
|
||||
**numberOfLines**: ?number
|
||||
|
||||
Truncates the text with an ellipsis after this many lines. Currently only supports `1`.
|
||||
|
||||
**onLayout**: ?function
|
||||
|
||||
Invoked on mount and layout changes with `{ nativeEvent: { layout: { x, y, width,
|
||||
height } } }`, where `x` and `y` are the offsets from the parent node.
|
||||
|
||||
**onPress**: ?function
|
||||
|
||||
This function is called on press.
|
||||
|
||||
**selectable**: ?boolean

|
||||
|
||||
**autoCorrect**: ?boolean = true
|
||||
|
||||
Automatically correct spelling mistakes (only available in iOS Safari).

in a document with `autofocus` is focused.
|
||||
|
||||
**blurOnSubmit**: ?boolean
|
||||
|
||||
If `true`, the text field will blur when submitted. The default value is `true`
|
||||
for single-line fields and `false` for multiline fields. Note, for multiline
|
||||
fields setting `blurOnSubmit` to `true` means that pressing return will blur
|
||||
the field and trigger the `onSubmitEditing` event instead of inserting a
|
||||
newline into the field.
|
||||
|
||||
**clearTextOnFocus**: ?boolean = false
|
||||
|
||||
If `true`, clears the text field automatically when focused.
|
||||
|
||||
**defaultValue**: ?string
|
||||
|
||||
Provides an initial value that will change when the user starts typing. Useful
|
||||
for simple use-cases where you don't want to deal with listening to events and
|
||||
updating the `value` prop to keep the controlled state in sync.
|
||||
|
||||
**editable**: ?boolean = true
|
||||
|
||||
If `false`, text is not editable (i.e., read-only).
|
||||
|
||||
**keyboardType**: enum('default', 'email-address', 'numeric', 'phone-pad', 'search', 'url', 'web-search') = 'default'
|
||||
|
||||
Determines which keyboard to open. (NOTE: Safari iOS requires an ancestral
|
||||
`<form action>` element to display the `search` keyboard).
|
||||
|
||||
(Not available when `multiline` is `true`.)
|
||||
|

||||
**onFocus**: ?function
|
||||
|
||||
Callback that is called when the text input is focused.
|
||||
|
||||
**onKeyPress**: ?function
|
||||
|
||||
Callback that is called when a key is pressed. This will be called with `{
|
||||
nativeEvent: { key: keyValue } }` where keyValue is 'Enter` or 'Backspace' for
|
||||
respective keys and the typed-in character otherwise including ' ' for space.
|
||||

||||
|
||||
**focus()**
|
||||
|
||||
Focus the underlying DOM input.
|
||||
|
||||
**isFocused()**
|
||||
|

# TouchableWithoutFeedback
|
||||
|
||||
Do not use unless you have a very good reason. All the elements that respond to
|
||||
press should have a visual feedback when touched. This is one of the primary
|
||||
reason a "web" app doesn't feel "native".
|
||||
|
||||
**NOTE: `TouchableWithoutFeedback` supports only one child**. If you wish to have
|
||||
several child components, wrap them in a View.
|
||||
|
||||
## Props
|
||||
|
||||
[...View props](./View.md)
|
||||
|
||||
**delayLongPress**: ?number
|
||||
|
||||
Delay in ms, from `onPressIn`, before `onLongPress` is called.
|
||||
|
||||
**delayPressIn**: ?number
|
||||
|
||||
Delay in ms, from the start of the touch, before `onPressIn` is called.
|
||||
|
||||
**delayPressOut**: ?number
|
||||
|
||||
Delay in ms, from the release of the touch, before `onPressOut` is called.
|
||||
|
||||
**disabled**: ?boolean
|
||||
|
||||
If `true`, disable all interactions for this component.
|
||||
|
||||
**onLongPress**: ?function
|
||||
|
||||
**onPress**: ?function
|
||||
|
||||
Called when the touch is released, but not if cancelled (e.g. by a scroll that steals the responder lock).
|
||||
|
||||
**onPressIn**: ?function
|
||||
|
||||
**onPressOut**: ?function
|
||||
|
||||
**pressRetentionOffset**: ?`{top: number, left: number, bottom: number, right: number}`
|
||||
|
||||
When the scroll view is disabled, this defines how far your touch may move off
|
||||
of the button, before deactivating the button. Once deactivated, try moving it
|
||||
back and you'll see that the button is once again reactivated! Move it back and
|
||||
forth several times while the scroll view is disabled. Ensure you pass in a
|
||||
constant to reduce memory allocations.

# View
|
||||
|
||||
`View` is the fundamental UI building block. It is a component that supports
|
||||
style, layout with flexbox, and accessibility controls. It can be nested
|
||||
inside another `View` and has 0-to-many children of any type.
|
||||
|
||||
Also, refer to React Native's documentation about the [Gesture Responder
|
||||
System](http://facebook.github.io/react-native/releases/0.22/docs/gesture-responder-system.html).
|
||||
|
||||
Unsupported React Native props: `collapsable`, `onAccessibilityTap`, `onMagicTap`.
|
||||
|
||||
## Props
|
||||
|
||||
NOTE: `View` will transfer all other props to the rendered HTML element.
|
||||
|
||||
**accessibilityLabel**: ?string
|
||||
|
||||
Overrides the text that's read by a screen reader when the user interacts
|
||||
with the element. (This is implemented using `aria-label`.)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility.md) for more information.
|
||||
|
||||
**accessibilityLiveRegion**: ?enum('assertive', 'none', 'polite')
|
||||
|
||||
Indicates to assistive technologies whether to notify the user when the view
|
||||
changes. The values of this attribute are expressed in degrees of importance.
|
||||
When regions are specified as `polite` (recommended), updates take low
|
||||
priority. When regions are specified as `assertive`, assistive technologies
|
||||
will interrupt and immediately notify the user. (This is implemented using
|
||||
[`aria-live`](http://www.w3.org/TR/wai-aria/states_and_properties#aria-live).)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility.md) for more information.
|
||||
|
||||
(web) **accessibilityRole**: ?enum(roles)
|
||||
|
||||
Allows assistive technologies to present and support interaction with the view
|
||||
in a manner that is consistent with user expectations for similar views of that
|
||||
type. For example, marking a touchable view with an `accessibilityRole` of
|
||||
`button`. (This is implemented using [ARIA roles](http://www.w3.org/TR/wai-aria/roles#role_definitions)).
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility.md) for more information.
|
||||
|
||||
**accessible**: ?boolean
|
||||
|
||||
When `true`, indicates that the view is an accessibility element (i.e.,
|
||||
focusable) and groups its child content. By default, all the touchable elements
|
||||
and elements with `accessibilityRole` of `button` and `link` are accessible.
|
||||
(This is implemented using `tabindex`.)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility.md) for more information.
|
||||
|
||||
**children**: ?element
|
||||
|
||||
Child content.
|
||||
|
||||
**hitSlop**: ?object
|
||||
|
||||
This defines how far a touch event can start away from the view (in pixels).
|
||||
Typical interface guidelines recommend touch targets that are at least 30 - 40
|
||||
points/density-independent pixels.
|
||||
|
||||
For example, if a touchable view has a height of `20` the touchable height can
|
||||
be extended to `40` with `hitSlop={{top: 10, bottom: 10, left: 0, right: 0}}`.
|
||||
|
||||
**importantForAccessibility**: ?enum('auto', 'no', 'no-hide-descendants', 'yes')
|
||||
|
||||
A value of `no` will remove the element from the tab flow.
|
||||
|
||||
A value of `no-hide-descendants` will hide the element and its children from
|
||||
assistive technologies. (This is implemented using `aria-hidden`.)
|
||||
|
||||
See the [Accessibility guide](../guides/accessibility.md) for more information.
|
||||
|
||||
**onLayout**: ?function
|
||||
|
||||
Invoked on mount and layout changes with `{ nativeEvent: { layout: { x, y, width,
|
||||
height } } }`, where `x` and `y` are the offsets from the parent node.
|
||||
|
||||
**onMoveShouldSetResponder**: ?function => boolean
|
||||
|
||||
Does this view want to "claim" touch responsiveness? This is called for every
|
||||
touch move on the `View` when it is not the responder.
|
||||
|
||||
**onMoveShouldSetResponderCapture**: ?function => boolean
|
||||
|
||||
If a parent `View` wants to prevent a child `View` from becoming responder on a
|
||||
move, it should have this handler return `true`.
|
||||
|
||||
**onResponderGrant**: ?function
|
||||
|
||||
The `View` is now responding to touch events. This is the time to highlight and
|
||||
show the user what is happening. For most touch interactions, you'll simply
|
||||
want to wrap your component in `TouchableHighlight` or `TouchableOpacity`.
|
||||
|
||||
**onResponderMove**: ?function
|
||||
|
||||
The user is moving their finger.
|
||||
|
||||
**onResponderReject**: ?function
|
||||
|
||||
Another responder is already active and will not release it to the `View`
|
||||
asking to be the responder.
|
||||
|
||||
**onResponderRelease**: ?function
|
||||
|
||||
Fired at the end of the touch.
|
||||
|
||||
**onResponderTerminate**: ?function
|
||||
|
||||
The responder has been taken from the `View`.
|
||||
|
||||
**onResponderTerminationRequest**: ?function
|
||||
|
||||
Some other `View` wants to become responder and is asking this `View` to
|
||||
release its responder. Returning `true` allows its release.
|
||||
|
||||
**onStartShouldSetResponder**: ?function => boolean
|
||||
|
||||
Does this view want to become responder on the start of a touch?
|
||||
|
||||
**onStartShouldSetResponderCapture**: ?function => boolean
|
||||
|
||||
If a parent `View` wants to prevent a child `View` from becoming the responder
|
||||
on a touch start, it should have this handler return `true`.
|
||||
|
||||
**pointerEvents**: ?enum('auto', 'box-only', 'box-none', 'none') = 'auto'
|
||||
|
||||
Controls whether the View can be the target of touch events. The enhanced
|
||||
`pointerEvents` modes provided are not part of the CSS spec, therefore,
|
||||
`pointerEvents` is excluded from `style`.
|
||||
|
||||
`box-none` is the equivalent of:
|
||||
|
||||
```css
|
||||
.box-none { pointer-events: none !important; }
|
||||
.box-none > * { pointer-events: auto; }
|
||||
```
|
||||
|
||||
`box-only` is the equivalent of:
|
||||
|
||||
```css
|
||||
.box-only { pointer-events: auto !important; }
|
||||
.box-only > * { pointer-events: none; }

# Getting started
|
||||
|
||||
This guide will help you to correctly configure build and test tools to work
|
||||
with React Native for Web. (Alternatively, you can quickly setup a local
|
||||
project using the starter kits listed in the README.)
|
||||
|
||||
It is recommended that your application provide a `Promise` and `Array.from`
|
||||
polyfill.
|
||||
|
||||
## Web packager
|
||||
|
||||
[Webpack](https://webpack.js.org) is a popular build tool for web apps. Below is an
|
||||
example of how to configure a build that uses [Babel](https://babeljs.io/) to
|
||||
compile your JavaScript for the web.
|
||||
|
||||
Create a `web/webpack.config.js` file:
|
||||
|
||||
```js
|
||||
// web/webpack.config.js
|
||||
|
||||
// This is needed for webpack to compile JavaScript.
|
||||
// Many OSS React Native packages are not compiled to ES5 before being
|
||||
// published. If you depend on uncompiled packages they may cause webpack build
|
||||
// errors. To fix this webpack can be configured to compile to the necessary
|
||||
// `node_module`.
|
||||
const babelLoaderConfiguration = {
|
||||
test: /\.js$/,
|
||||
// Add every directory that needs to be compiled by Babel during the build
|
||||
include: [
|
||||
path.resolve(__dirname, 'src'),
|
||||
path.resolve(__dirname, 'node_modules/react-native-uncompiled')
|
||||
],
|
||||
use: {
|
||||
loader: 'babel-loader',
|
||||
options: {
|
||||
cacheDirectory: true,
|
||||
// The 'react-native' preset is recommended (or use your own .babelrc)
|
||||
presets: ['react-native']
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
// This is needed for webpack to import static images in JavaScript files
|
||||
const imageLoaderConfiguration = {
|
||||
test: /\.(gif|jpe?g|png|svg)$/,
|
||||
use: {
|
||||
loader: 'url-loader',
|
||||
options: {
|
||||
name: '[name].[ext]'
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
module.exports = {
|
||||
// ...the rest of your config
|
||||
|
||||
module: {
|
||||
rules: [
|
||||
babelLoaderConfiguration,
|
||||
imageLoaderConfiguration
|
||||
]
|
||||
},
|
||||
|
||||
plugins: [
|
||||
// `process.env.NODE_ENV === 'production'` must be `true` for production
|
||||
// builds to eliminate development checks and reduce build size. You may
|
||||
// wish to include additional optimizations.
|
||||
new webpack.DefinePlugin({
|
||||
'process.env.NODE_ENV': JSON.stringify('production')
|
||||
})
|
||||
],
|
||||
|
||||
resolve: {
|
||||
// Maps the 'react-native' import to 'react-native-web'.
|
||||
alias: {
|
||||
'react-native': 'react-native-web'
|
||||
},
|
||||
// If you're working on a multi-platform React Native app, web-specific
|
||||
// module implementations should be written in files using the extension
|
||||
// `.web.js`.
|
||||
extensions: [ '.web.js', '.js' ]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
To run in development:
|
||||
|
||||
```
|
||||
./node_modules/.bin/webpack-dev-server -d --config web/webpack.config.js --inline --hot --colors
|
||||
```
|
||||
|
||||
To build for production:
|
||||
|
||||
```
|
||||
./node_modules/.bin/webpack -p --config web/webpack.config.js
|
||||
```
|
||||
|
||||
Please refer to the Webpack documentation for more information on configuration.
|
||||
|
||||
## Web entry
|
||||
|
||||
Create a `index.web.js` file (or simply `index.js` for web-only apps).
|
||||
|
||||
### Client-side rendering
|
||||
|
||||
Rendering using `AppRegistry`:
|
||||
|
||||
```js
|
||||
// index.web.js
|
||||
|
||||
import App from './src/App';
|
||||
import React from 'react';
|
||||
import ReactNative, { AppRegistry } from 'react-native';
|
||||
|
||||
// register the app
|
||||
AppRegistry.registerComponent('App', () => App);
|
||||
|
||||
AppRegistry.runApplication('App', {
|
||||
initialProps: {},
|
||||
rootTag: document.getElementById('react-app')
|
||||
});
|
||||
```
|
||||
|
||||
Rendering within existing web apps is also possible using `ReactNative`:
|
||||
|
||||
```js
|
||||
import AppHeader from './src/AppHeader';
|
||||
import React from 'react';
|
||||
import ReactNative from 'react-native';
|
||||
|
||||
ReactNative.render(<AppHeader />, document.getElementById('react-app-header'))
|
||||
```
|
||||
|
||||
And finally, `react-native-web` components will also be rendering within a tree
|
||||
produced by calling `ReactDOM.render` (i.e., an existing web app), but
|
||||
otherwise it is not recommended.
|
||||
|
||||
### Server-side rendering
|
||||
|
||||
Server-side rendering is supported using the `AppRegistry`:
|
||||
|
||||
```js
|
||||
import App from './src/App';
|
||||
import ReactDOMServer from 'react-dom/server'
|
||||
import ReactNative, { AppRegistry } from 'react-native'
|
||||
|
||||
// register the app
|
||||
AppRegistry.registerComponent('App', () => App)
|
||||
|
||||
// prerender the app
|
||||
const { element, stylesheets } = AppRegistry.getApplication('App', { initialProps });
|
||||
const initialHTML = ReactDOMServer.renderToString(element);
|
||||
const initialStyles = stylesheets.map((sheet) => ReactDOMServer.renderToStaticMarkup(sheet)).join('\n');
|
||||
|
||||
// construct HTML document
|
||||
const document = `
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<head>
|
||||
${initialStyles}
|
||||
</head>
|
||||
<body>
|
||||
${initialHTML}
|
||||
`
|
||||
```
|
||||
|
||||
## Web-specific code
|
||||
|
||||
Minor platform differences can use the `Platform` module.
|
||||
|
||||
```js
|
||||
import { Platform } from 'react-native';
|
||||
|
||||
const styles = StyleSheet.create({
|
||||
height: (Platform.OS === 'web') ? 200 : 100,
|
||||
});
|
||||
```
|
||||
|
||||
More significant platform differences should use platform-specific files (see
|
||||
the webpack configuration above for resolving `*.web.js` files):
|
||||
|
||||
For example, with the following files in your project:
|
||||
|
||||
```
|
||||
MyComponent.android.js
|
||||
MyComponent.ios.js
|
||||
MyComponent.web.js
|
||||
```
|
||||
|
||||
And the following import:
|
||||
|
||||
```js
|
||||
import MyComponent from './MyComponent';
|
||||
```
|
||||
|
||||
React Native will automatically import the correct variant for each specific
|
||||
target platform.
|
||||
|
||||
## Testing with Jest
|
||||
|
||||
[Jest](https://facebook.github.io/jest/) also needs to map `react-native` to `react-native-web`.
|
||||
|
||||
```
|
||||
"jest": {
|
||||
"moduleNameMapper": {
|
||||
"react-native": "<rootDir>/node_modules/react-native-web"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Please refer to the Jest documentation for more information.

# Known issues
|
||||
|
||||
## Safari flexbox performance
|
||||
|
||||
Safari version prior to 10.1 can suffer from extremely [poor flexbox
|
||||
performance](https://bugs.webkit.org/show_bug.cgi?id=150445). The recommended
|
||||
way to work around this issue (as used on mobile.twitter.com) is to set
|
||||
`display:block` on Views in your element hierarchy that you know don't need
|
||||
flexbox layout.
|
||||
|
||||
## Missing modules and components
|
||||
|
||||
Not all of the views present on iOS/Android are currently available on Web. We
|
||||
are very much interested in the community's feedback on the next set of modules
|
||||
and views.
|
||||
|
||||
Not all the modules or views for iOS/Android can be implemented on Web. In some
|
||||
cases it will be necessary to use a Web counterpart or to guard the use of a
|
||||
module with `Platform.OS` (e.g. `NativeModules`)
|
||||
|
||||
## Missing component props
|
||||
|
||||
There are properties that do not work across all platforms. All web-specific
|
||||
props are annotated with `(web)` in the documentation.
|
||||
|
||||
## Platform parity
|
||||
|
||||
There are some known issues in React Native where APIs could be made more
|
||||
consistent between platforms. For example, React Native for Web includes
|
||||
`ActivityIndicator` and a horizontal `ProgressBar` for Web use, in anticipation
|
||||
of the convergence between the iOS and Android components in React Native.

# babel-plugin-react-native-web
|
||||
|
||||
[![npm version][package-badge]][package-url] [](https://reactjs.org/docs/how-to-contribute.html#your-first-pull-request)
|
||||
|
||||
A Babel plugin that will alias `react-native` to `react-native-web` and exclude
|
||||
any modules not required by your app (keeping bundle size down).
|
||||
|
||||
## Installation
|
||||
|
||||
```
|
||||
yarn add --dev babel-plugin-react-native-web
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
**.babelrc**
|
||||
|
||||
```
|
||||
{
|
||||
"plugins": ["react-native-web"]
|
||||
}
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
NOTE: `react-native-web` internal paths are _not stable_ and you must not rely
|
||||
on them. Always use the Babel plugin to optimize your build. What follows is an
|
||||
example of the rewrite performed by the plugin.
|
||||
|
||||
**Before**
|
||||
|
||||
```js
|
||||
import { StyleSheet, View } from 'react-native';
|
||||
```
|
||||
|
||||
**After**
|
||||
|
||||
```js
|
||||
import StyleSheet from 'react-native-web/dist/exports/StyleSheet';
|
||||
import View from 'react-native-web/dist/exports/View';
|
||||
```

# benchmarks
|
||||
|
||||
Try the [benchmarks app](https://necolas.github.io/react-native-web/benchmarks) online.
|
||||
|
||||
To run the benchmarks locally:
|
||||
|
||||
```
|
||||
yarn benchmarks
|
||||
open ./packages/benchmarks/dist/index.html
|
||||
```
|
||||
|
||||
Develop against these benchmarks:
|
||||
|
||||
```
|
||||
yarn compile --watch
|
||||
yarn benchmarks --watch
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
These benchmarks are approximations of extreme cases that libraries may
|
||||
encounter. Their purpose is to provide an early-warning signal for performance
|
||||
regressions. Each test report includes the mean and standard deviation of the
|
||||
timings, and approximations of the time spent in scripting (S) and layout (L).
|
||||
|
||||
The components used in the render benchmarks are simple enough to be
|
||||
implemented by multiple UI or style libraries. The benchmark implementations
|
||||
and the features of the style libraries are _only approximately equivalent in
|
||||
functionality_.
|
||||
|
||||
No benchmark will run for more than 20 seconds.
|
||||
|
||||
### Mount deep/wide tree
|
||||
|
||||
These cases look at the performance of mounting and rendering large trees of
|
||||
elements that use static styles.
|
||||
|
||||
### Update dynamic styles
|
||||
|
||||
This case looks at the performance of repeated style updates to a large mounted
|
||||
tree. Some libraries choose to inject new styles for each "dynamic style",
|
||||
whereas others choose to use inline styles. Libraries without built-in support
|
||||
for dynamic styles (i.e., they rely on user-authored inline styles) are not
|
||||
included.
|
||||
|
||||
