Channel

The Channel component is the main entry point for many Stream Chat customizations and contains the majority of the content providers and a significant amount of the logic utilized by Stream Chat for React Native. Components, custom and out of the box, channel information, and UI integrated chat functions are disseminated by the contexts contained in Channel. MessageList, MessageInput, and Thread all rely on Channel to function correctly.

Basic Usage

Channel takes an instance of a StreamChat channel as a prop. You can create a channel, or if you are navigating from the ChannelList, access the selected channel via the parameter passed to the onSelect function.

import { StreamChat } from 'stream-chat';
import { Channel, Chat, MessageInput, MessageList, OverlayProvider } from 'stream-chat-react-native';

const client = StreamChat.getInstance('api_key');

export const App = () => {
  const [channel, setChannel] = useState();

  useEffect(() => {
    const createAndWatchChannel = async () => {
      const newChannel = client.channel('messaging', 'channel_id');
      await newChannel.watch();
      setChannel(newChannel);
    };

    createAndWatchChannel();
  }, []);

  return (
    <OverlayProvider>
      <Chat client={client}>
        <Channel channel={channel}>
          <MessageList />
          <MessageInput />
        </Channel>
      </Chat>
    </OverlayProvider>
  );
};

Context Providers

Channel contains providers for the ChannelContext, KeyboardContext, MessageInputContext, MessagesContext, PaginatedMessageListContext, SuggestionsContext, ThreadContext, and TypingContext. These can be accessed using the corresponding hooks.

Context	Hook
ChannelContext	useChannelContext
KeyboardContext	useKeyboardContext
MessageInputContext	useMessageInputContext
MessagesContext	useMessagesContext
PaginatedMessageListContext	usePaginatedMessageListContext
SuggestionsContext	useSuggestionsContext
ThreadContext	useThreadContext
TypingContext	useTypingContext

UI Customizations

Channel is the entry point for customizing the majority of the Stream Chat for React Native SDK. The UI can be tailored to your design by replacing any number of components with custom components. Custom components provided as props to Channel will be utilized throughout the SDK where appropriate.

Customizing the message avatar can be done easily by providing a custom component to the appropriate prop.

import { Image } from 'react-native';
import { Channel, useMessageContext } from 'stream-chat-react-native';

const CustomAvatar = () => {
  const { message } = useMessageContext();

  return <Image source={{ uri: message.user?.image }} />;
};

<Channel MessageAvatar={CustomAvatar} />;

The additionalInfo prop is handy for getting information from certain click events. A good example of this is getting the user details when a textMention (for example @Enigma-I-am) is clicked.

For example:

    <Channel
      onPressMessage={({ additionalInfo, defaultHandler, emitter }) => {

          if (emitter === 'textMention') {
            console.log(additionalInfo?.user);
            return;
          }

          if (emitter === 'card' || emitter === 'textLink') {
            console.log(additionalInfo?.url);
            return;
          }

          if (emitter === 'fileAttachment') {
            console.log(additionalInfo?.attachment);
            return;
          }
