Example

import React from 'react'
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 example/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

  title: string
  value: string
  messageId?: any
}

interface QuickReplies {
  type: 'radio' | 'checkbox'

Imperative methods

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 almost 2 solutions to fix it:
- adding KeyboardAvoidingView after GiftedChat see this comment
- adding an opaque background status bar on app.json https://docs.expo.io/versions/latest/guides/configuration.html#androidstatusbar
If you plan to use GiftedChat inside a Modal, see #200.

Notes for local development

Install yarn add -g expo-cli
expo start
