This is beta documentation for Stream Chat React Native SDK v9. For the latest stable version, see the latest version (v8) .

MessageContext

MessageContext is provided by Message. If you are not familiar with the React Context API, see the React docs.

Best Practices

Use useMessageContext for consistent access and typings.
Keep message-level logic local; avoid reaching into channel state here.
Use actionsEnabled and canModifyMessage to gate UI actions.
Avoid heavy computations in message contexts to prevent list jank.
Treat attachment arrays as read-only and render them efficiently.

Basic Usage

Consume MessageContext in any child of Message:

import { useContext } from "react";
import { MessageContext } from "stream-chat-react-native";

const { isMyMessage, message, files } = useContext(MessageContext);

Alternatively, use the useMessageContext hook.

import { useMessageContext } from "stream-chat-react-native";

const { isMyMessage, message, files } = useMessageContext();
