Advanced example

See example/App.js for a working demo!

Message object

e.g. Chat Message

{
  _id: 1,
  text: 'My message',
  createdAt: new Date(Date.UTC(2016, 5, 11, 17, 20, 0)),
  user: {
    _id: 2,
    name: 'React Native',
    avatar: 'https://facebook.github.io/react/img/logo_og.png',
  },
  image: 'https://facebook.github.io/react/img/logo_og.png',
  // Any additional custom parameters are passed through
}

e.g. System Message

{
  _id: 1,
  text: 'This is a system message',
  createdAt: new Date(Date.UTC(2016, 5, 11, 17, 20, 0)),
  system: true,
  // Any additional custom parameters are passed through
}

• parsePatterns (Function) - Custom parse patterns for react-native-parsed-text used to linkify message content (like URLs and phone numbers), e.g.:

  <GiftedChat
    parsePatterns={(linkStyle) => [
      { type: 'phone', style: linkStyle, onPress: this.onPressPhoneNumber },
      { pattern: /#(\w+)/, style: { ...linkStyle, styles.hashtag }, onPress: this.onPressHashtag },
    ]}
  />
  

Imperative methods

• focusTextInput() - Open the keyboard and focus the text input box

Notes for Redux

The messages prop should work out-of-the-box with Redux. In most cases this is all you need.

If you decide to specify a text prop, GiftedChat will no longer manage its own internal text state and will defer entirely to your prop. This is great for using a tool like Redux, but there's one extra step you'll need to take: simply implement onInputTextChanged to receive typing events and reset events (e.g. to clear the text onSend):

<GiftedChat
  text={customText}
  onInputTextChanged={(text) => this.setCustomText(text)}
  /* ... */ />

Notes for Android

If you are using Create React Native App / Expo, no Android specific installation steps are required -- you can skip this section. Otherwise we recommend modifying your project configuration as follows.

• Make sure you have android:windowSoftInputMode="adjustResize" in your AndroidManifest.xml:

  <activity
    android:name=".MainActivity"
    android:label="@string/app_name"
    android:windowSoftInputMode="adjustResize"
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
  

• If you plan to use GiftedChat inside a Modal, see #200.

Notes for local development

You can use wml to keep the example app in sync with any changes you make to the library during development. Steps:

1. Install it: npm install -g wml
2. Configure it: wml add . example/node_modules/react-native-gifted-chat from the root directory
3. cd example
4. npm start
5. wml start in another terminal window (doesn't matter where)

Note that it's important for wml start to come after npm start, or you'll get Can't find entry file index.js errors. If you have any issues, you can clear your watches using watchman watch-del-all and try again.
