Live streams in Laravel

One person presents live to everyone watching: the picture, a chat beside it, reactions, and the count of who watches. The host goes live from the browser, a phone or OBS. Viewers may be signed in or not.

Who is who

Your app declares streams beside its rooms and calls, in boot() of a service provider. The rule says who each person is in the stream:

$this->callAfterResolving( Realtime::class, function ( Realtime $realtime ) {
    // The show of the shop, show:mugs: Ann presents it, and everyone else watches and writes in its chat, signed in or not.
    $realtime->streams( 'show:{id}', function ( $user, array $p ) {
        if ( 'mugs' !== $p['id'] ) {
            return false;
        }

        return null !== $user && 'Ann' === User::find( $user )?->name ? 'host' : 'viewer';
    }, [ 'reactions' => true ] );
} );

• The answer: false, 'host' or 'viewer', or an array: role, info (what others see of them), chat (write or read), mod (keeps the chat), src and quality (what the host sends).
• A visitor who is not signed in comes with $user null, and may only be a viewer.
• The settings of the stream, the third argument: reactions, people and chat (offline, links, fresh), each a value or a closure of the parts of the name (live streams in depth).

The calls route of the browser (/wordplus/realtime/calls) answers streams too: nothing more to add.

The page

const calls = await rt.calls();
const show = await calls.stream( 'show:mugs' );

show.watch( document.querySelector( '#show video' ) );      // the picture and its sound
show.on( 'state', ( state ) => draw( state ) );            // idle, live, ended
show.on( 'viewers', ( n ) => ( count.textContent = `${ n } watching` ) );
show.on( 'message', ( m ) => addLine( m.from.name, m.text ) );
await show.chat.send( 'Hello!' );

if ( show.role === 'host' ) {
    await show.preview();    // the camera, shown in the same video
    await show.goLive();
}

The show card of the Example Shop does exactly this, in showCard() of resources/js/shop.js.
