import { GiftedChat } from 'react-native-gifted-chat'

class Example extends React.Component {
  state = {
    messages: [],
  }

  componentWillMount() {
    this.setState({
      messages: [
        {
          _id: 1,
          text: 'Hello developer',
          createdAt: new Date(),
          user: {
            _id: 2,
            name: 'React Native',
            avatar: 'https://placeimg.com/140/140/any',
          },
        },
      ],
    })
  }

  onSend(messages = []) {
    this.setState(previousState => ({
      messages: GiftedChat.append(previousState.messages, messages),
    }))
  }

  render() {
    return (
      <GiftedChat
        messages={this.state.messages}
        onSend={messages => this.onSend(messages)}
        user={{
          _id: 1,
        }}
      />
    )
  }
}

Advanced example

See App.js for a working demo!

"Slack" example

See the files in example-slack-message for an example of how to override the default UI to make something that looks more like Slack -- with usernames displayed and all messages on the left.

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',
  // You can also add a video prop:
  video: 'http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4',
  // 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
}

e.g. Chat Message with Quick Reply options

See PR #1211

interface Reply {
  title: string
  value: string
  messageId?: any
}

interface QuickReplies {
  type: 'radio' | 'checkbox'
  values: Reply[]
  keepIt?: boolean
}
  {
    _id: 1,
    text: 'This is a quick reply. Do you love Gifted Chat? (radio) KEEP IT',
    createdAt: new Date(),
    quickReplies: {
      type: 'radio', // or 'checkbox',
      keepIt: true,
      values: [
        {
          title: 'πŸ˜‹ Yes',
          value: 'yes',
        },
        {
          title: 'πŸ“· Yes, let me show you with a picture!',
          value: 'yes_picture',
        },
        {
          title: '😞 Nope. What?',
          value: 'no',
        },
      ],
    },
    user: {
      _id: 2,
      name: 'React Native',
    },
  },
  {
    _id: 2,
    text: 'This is a quick reply. Do you love Gifted Chat? (checkbox)',
    createdAt: new Date(),
    quickReplies: {
      type: 'checkbox', // or 'radio',
      values: [
        {
          title: 'Yes',
          value: 'yes',
        },
        {
          title: 'Yes, let me show you with a picture!',
          value: 'yes_picture',
        },
        {
          title: 'Nope. What?',
          value: 'no',
        },
      ],
    },
    user: {
      _id: 2,
      name: 'React Native',
    },
  }

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">
  • For Expo, there are at least 2 solutions to fix it:

    • Append KeyboardAvoidingView after GiftedChat. This should only be done for Android, as KeyboardAvoidingView may conflict with the iOS keyboard avoidance already built into GiftedChat, e.g.:
<View style={{ flex: 1 }}>
   <GiftedChat />
   {
      Platform.OS === 'android' && <KeyboardAvoidingView behavior="padding" />
   }
</View>

If you use React Navigation, additional handling may be required to account for navigation headers and tabs. KeyboardAvoidingView's keyboardVerticalOffset property can be set to the height of the navigation header and tabBarOptions.keyboardHidesTabBar can be set to keep the tab bar from being shown when the keyboard is up. Due to a bug with calculating height on Android phones with notches, KeyboardAvoidingView is recommended over other solutions that involve calculating the height of the window.

Notes for local development

Native

  1. Install yarn add -g expo-cli
  2. expo start

react-native-web

With expo

  1. Install yarn add -g expo-cli
  2. expo start -w

With create-react-app

  1. yarn add -D react-app-rewired
  2. touch config-overrides.js
module.exports = function override(config, env) {
  config.module.rules.push({
    test: /\.js$/,
    exclude: /node_modules[/\\](?!react-native-gifted-chat|react-native-lightbox|react-native-parsed-text)/,
    use: {
      loader: 'babel-loader',
      options: {
        babelrc: false,
        configFile: false,
        presets: [
          ['@babel/preset-env', { useBuiltIns: 'usage' }],
          '@babel/preset-react',
        ],
        plugins: ['@babel/plugin-proposal-class-properties'],
      },
    },
  })

  return config
}
