laravel-echo

What is laravel-echo?

Laravel Echo is a JavaScript library that makes it easy to work with WebSockets in a Laravel application. It provides a simple API for subscribing to channels and listening for events broadcast by your Laravel application.

What are laravel-echo's main functionalities?

Subscribing to Channels

This feature allows you to subscribe to a public channel and listen for events. In this example, the client subscribes to the 'orders' channel and listens for the 'OrderShipped' event.

Echo.channel('orders').listen('OrderShipped', (e) => { console.log(e.order); });

Private Channels

This feature allows you to subscribe to private channels that require authentication. In this example, the client subscribes to a private 'orders' channel specific to a user and listens for the 'OrderShipped' event.

Echo.private('orders.' + userId).listen('OrderShipped', (e) => { console.log(e.order); });

Presence Channels

Presence channels build on the concept of private channels and allow you to track the presence of users in a channel. In this example, the client joins a 'chat' room and logs the users currently in the room, as well as users joining and leaving.

Echo.join('chat.' + roomId).here((users) => { console.log(users); }).joining((user) => { console.log(user.name); }).leaving((user) => { console.log(user.name); });

Notifications

This feature allows you to listen for notifications sent to a user. In this example, the client subscribes to a private channel for a specific user and listens for notifications.

Echo.private('App.User.' + userId).notification((notification) => { console.log(notification.type); });
