ChannelPreview UI
The ChannelPreview UI component receives props via the ChannelPreview wrapper, and
these props are a combination of the ChannelPreview props with additional UI specific items. The wrapper also handles the required logic
while the UI component is responsible for the UI display and the click functionality for channel selection.
This UI component is set via the Preview prop on ChannelList, and if nothing is provided then the default is used, ChannelPreviewMessenger.
Basic Usage#
This UI component is very customizable; below is an example of how to use the Preview prop, and for a more involved step-by-step guide, using the many provided props,
see ChannelPreview Code Example.
const YourCustomChannelPreview = (props) => { // render custom preview info here};
<ChannelList Preview={(previewProps) => <YourCustomChannelPreview {...previewProps} />}/>;Props#
Required channel#
This required prop is the channel to be previewed; comes from either the channelRenderFilterFn or usePaginatedChannels call from
