useChannelUpdated

Subscribes to channel.updated events and applies channel updates to your ChannelList state.

Best Practices

• Use this hook where channel list state (setChannels) is owned.
• Provide a custom onChannelUpdated only when default update behavior is insufficient.
• Keep custom update handlers idempotent and side-effect free.
• Avoid mutating the previous channels array directly in custom handlers.
• Use this hook once per list state owner to prevent duplicate updates.

Usage

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

useChannelUpdated({
  setChannels,
  onChannelUpdated: (setChannels, event) => {
    setChannels(
      (channels) =>
        channels?.map((channel) =>
          channel.cid === (event.cid || event.channel?.cid) ? channel : channel,
        ) ?? channels,
    );
  },
});
