MessageList

The MessageList component renders a scrollable list of messages. The UI for each individual message is rendered conditionally based on its message.type value. The list renders date separators, new message notifications, system messages, deleted messages, and standard messages containing text and/or attachments.

By default, the MessageList loads the most recent 25 messages held in the channel.state. More messages are fetched from the Stream Chat API and loaded into the DOM on scrolling up the list. The currently loaded messages are held in the ChannelStateContext and can be referenced with our custom hook.

const { messages } = useChannelStateContext();

The MessageList has no required props and by default pulls overridable data from the various contexts established in the Channel component. Customization of the messages rendered within the list is handled by the Message UI component.

Basic Usage

As a context consumer, the MessageList component must be rendered as a child of the Channel component. It can be rendered with or without a provided messages prop. Providing your own messages value will override the default value drawn from the ChannelStateContext.

Example 1 - without messages prop

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

Example 2 - with messages prop

const customMessages = [  // array of messages];
<Chat client={client}>  <ChannelList />  <Channel>    <MessageList messages={customMessages} />    <MessageInput />  </Channel></Chat>;
