How do I receive data when the client initially joins a channel?
Something like this:
Echo.channel('channel-name')
.onjoin(function (data) {
console.log(data) // Data received from server
})
As soon when the client joins, the server should respond with data, preferably with PHP.
Presence channels return information about the users in the channel at the time the client subscribes.
If you require other data from your server then you could send a post request to your server to get the information. You could invoke this in a pusher:subscription_succeeded binding so it occurs as soon as the subscription is established.
