Chat

The Chat component is a React Context provider that wraps the entire Stream Chat application. It provides the ChatContext to its children, which includes the StreamChat client instance. All other components within the library must be nested as children of Chat to maintain proper functionality.

Basic Usage

The Chat component does not inject any UI, so its implementation is fairly simple. Once an instance of the StreamChat client has been created, you pass the client object as a prop to add it to the ChatContext.

<Chat client={client}>
  <Channel channel={channel}>
    <MessageList />
    <MessageInput />
  </Channel>
</Chat>

Any child of the Chat component has access to the ChatContext. Each React Context in the component library can be accessed with one of our custom hooks, which must be imported individually. The ChatContext values are accessed with useChatContext hook.

const { client } = useChatContext();

useImageFlagEmojisOnWindows

Windows 10 does not support country flag emojis out of the box. It chooses to render these emojis as characters instead. Stream Chat can override this behavior by loading a custom web font that will render images instead (PNGs or SVGs depending on the platform). Set this prop to true if you want to use these custom emojis for Windows users.

caution

If you're moving from older versions to 11.0.0 then make sure to import related stylesheet from stream-chat-react/css/v2/emoji-replacement.css as it has been removed from our main stylesheet to reduce final bundle size for integrators who do not wish to use this feature.

Type	Default
boolean	false
