Getting started

Installation

Install dependencies

Yarn:

yarn add react-native-gifted-chat react-native-reanimated react-native-safe-area-context

Npm:

npm install --save react-native-gifted-chat react-native-reanimated react-native-safe-area-context

Expo

npx expo install react-native-gifted-chat react-native-reanimated react-native-safe-area-context

Non-expo users

npx pod-install

Setup react-native-safe-area-context

Follow guide: react-native-safe-area-context

react-native-video and expo-av

• Both dependencies are removed since 0.11.0.
• You still be able to provide a video but you need to provide renderMessageVideo prop.

Testing

TEST_ID is exported as constants that can be used in your testing library of choice

Gifted Chat uses onLayout to determine the height of the chat container. To trigger onLayout during your tests, you can run the following bits of code.

const WIDTH = 200; // or any number
const HEIGHT = 2000; // or any number

const loadingWrapper = getByTestId(TEST_ID.LOADING_WRAPPER)
fireEvent(loadingWrapper, 'layout', {
  nativeEvent: {
    layout: {
      width: WIDTH,
      height: HEIGHT,
    },
  },
})

Example

import React, { useState, useCallback, useEffect } from 'react'
import { GiftedChat } from 'react-native-gifted-chat'

export function Example() {
  const [messages, setMessages] = useState([])

  useEffect(() => {
    setMessages([
      {
        _id: 1,
        text: 'Hello developer',
        createdAt: new Date(),
        user: {
          _id: 2,
          name: 'React Native',
          avatar: 'https://placeimg.com/140/140/any',
        },
      },
    ])
  }, [])

  const onSend = useCallback((messages = []) => {
    setMessages(previousMessages =>
      GiftedChat.append(previousMessages, messages),
    )
  }, [])

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

Advanced example

See App.tsx for a working demo!

"Slack" example

See the files in example/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

export interface IMessage {
  _id: string | number
  text: string
  createdAt: Date | number
  user: User
  image?: string
  video?: string
  audio?: string
  system?: boolean
  sent?: boolean
  received?: boolean
  pending?: boolean
  quickReplies?: QuickReplies
}

{
  _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',
  // Mark the message as sent, using one tick
  sent: true,
  // Mark the message as received, using two tick
  received: true,
  // Mark the message as pending with a clock loader
  pending: true,
  // 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?: number | string
}

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',

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.

• adding an opaque background status bar on app.json (even though android:windowSoftInputMode="adjustResize" is set internally on Expo's Android apps, the translucent status bar causes it not to work): https://docs.expo.io/versions/latest/guides/configuration.html#androidstatusbar

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