Laravel broadcast works for one user

Question

I am doing a notification tracking by following a simple example from the internet. Unfortunately, so far, I've managed to make it work for only one user. When I open two users, the message from A to B works, but from B to A does not work. Can someone help me?

channels.php

Broadcast::channel('App.User.{id}', function ($user, $id) {
    return (int) $user->id === (int) $id;
});

bootstrap.js

window.Pusher = require('pusher-js');
import Echo from "laravel-echo";

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: 'some-key',
    cluster: 'mt1',
    forceTLS: true
});

global.js

    var urlChannel = 'App.User.' + $('#user_logado_id').val();
    window.Echo.private(urlChannel)
        .notification((notification) => {
            addNotificacao(notification);
        });

Send notification to user.

$user->notify(new NotificacaoPadrao($param));

I would like notifications to be sent to all users.

You can pass both sender and receiver user_id. So in your channels.php:

Broadcast::channel('App.User.{from_user_id}.{to_user_id}', function ($user, $from_user_id, $to_user_id) {
    return (int) $user->id === (int) $from_user_id || (int) $user->id === (int) $to_user_id;
});

When doing this, you should remember that both user must call the same channel name. E.g. If you have user 1 and 2 sending messages to each other the URL channel of both should be 'App.User.1.2' and NOT 'App.User.2.1'.

Actually there are many ways to do this, one solution is what I mentioned above, but this only works on 1-1 messaging, NOT group message. When you want to send a group message you should create 2 tables: channels (id, name) and channel_users (id, channel_id, user_id). And your broadcasts channel route will be like this:

Broadcast::channel('App.User.{channel_id}', function ($user, $channel_id) {
    return ChannelUser::where('channel_id', $channel_id)->where('user_id', $user->id)->exists();
});
