Chat

Chat provides the ChatContext, TranslationContext, and ThemeContext to its child components. Chat is the second highest level component in the Stream Chat for React Native library with only the OverlayProvider at a higher level.

Chat is also responsible for tracking the health of the WebSocket connection with Stream Chat server. The value isOnline provided by the ChatContext indicates the status of the connection.

General Usage

Chat should be rendered inside of the OverlayProvider at a high level of your application, similar to the OverlayProvider.

tip

We recommend using only one instance of Chat provider per application unless absolutely needed.

import { StreamChat } from 'stream-chat';
import { ChannelList, Chat, OverlayProvider } from 'stream-chat-react-native';

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

export const App = () => (
  <OverlayProvider>
    <Chat client={client}>
      <ChannelList />
    </Chat>
  </OverlayProvider>
);

Context Providers

Chat contains providers for the ChatContext, ThemeContext, and TranslationContext. These can be accessed using the corresponding hooks.

Context	Hook
ChatContext	useChatContext
ThemeContext	useTheme
TranslationContext	useTranslationContext

closeConnectionOnBackground

When set to false the WebSocket connection won't disconnect when sending the app to the background. To receive push notifications it's necessary that user doesn't have an active WebSocket connection. By default the WebSocket connection is disconnected when the app goes to the background, and reconnects when app comes to the foreground.
