useUsers for PubNub Chat Components for React
Migrate to Chat SDK
PubNub will stop supporting Chat Components on January 1, 2025 but you are welcome to contribute. Learn how to migrate to the Chat SDK here.
The hook returns a list of User ID metadata objects, optionally including the custom data object for each.
User ID / UUID
User ID is also referred to as UUID
/uuid
in some APIs and server responses but holds the value of the userId
parameter you set during initialization.
Pagination is handled internally. You can adjust the limit
of returned users 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 will react to updates and removals of already-fetched users.
However, this behavior requires a living subscription to users getting updated - this should be handled by the components.
const [users, fetchPage, total, error, isLoading] = useUsers();
return <Chat users={users}>{/* Add components here */}</Chat>;
