useChannelMembers for PubNub Chat Components for React Native

The hook returns a list of members in a channel.

The list includes user metadata for members that have additional metadata stored in the database. Pagination is handled internally. You can adjust the limit of returned members on a single call (max/default 100) and call a function returned by the hook to get another page of results.

This hook also sets up a listener that reacts to removals of already fetched members. Updates and new memberships are not handled due to technical limitations. However, this behavior requires a living subscription to the channel getting updated - this should be handled by the components.

const [members, fetchPage, refetchChannelMembers, total, error] = useChannelMembers({
  channel: "channel",
});

return (
  <Chat {...{ options }}>
    <MemberList members={members} />
  </Chat>
);
