What is the purpose and how to use Broadcasting in Laravel?

Question

The version 5.3 of Laravel has some news, as the Broadcasting, for example.

I read the documentation, but I could not understand very well on the subject.

I saw that it has some relation (whether direct or indirect, I do not know) with the Websockets. I also saw that, in the folder routes, there is a file called channels.php, where there is an example code:

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

I wanted to know more deeply:

• What is this Broadcasting in Laravel?

• In what situations can I use it, for example?

• What is the relationship between Laravel Broadcasting and Websockets?

_{The question is intended to have the content in the Portuguese language, due to not finding anything on the Internet in our language}

Answer 1

Broadcast serves many things, example you want to trigger a push for all customers at the same time within the application.

Example: A hospital panel needs to update which beds are available or occupied, Broadcast can update all screens according to the update made.

All other answers are in the documentation.

Answer 2

The purpose is to work with Real-time events ex: has 2 open pages one that lists users and another that adds, When adding a new, the page that lists automatically receives the new item.
