useChannels for PubNub Chat Components for React Native

USED BY THE OLD IA, PLEASE DISREGARD

The hook returns a list of channel metadata objects, optionally including the custom data object for each.

Pagination is handled internally. You can adjust the limit of returned channels 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 updates and removals of already fetched channels.

However, this behavior requires a living subscription to channels getting updated - this should be handled by the components.

1const [channels, fetchPage, total, error, isLoading] = useChannels();

4 <Chat {...{ options }}>
5 <ChannelList channels={channels} />
