react-native-video and expo-av

• Both dependencies are removed since 0.11.0.

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 'expo-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,
      }}
    />
  )
}

Message object

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
}
