Introduction

Unlock the power of Laravel's broadcasting system with Wave. Imagine that real-time server broadcasting is possible over native HTTP without any WebSockets setup. Meet the Server-sent Events 🛜 Works seamlessly with Laravel's default redis broadcasting driver and supports Laravel Echo.

Experience it live with our demo streaming tweets 🐤.

Server-Sent Events (SSE) is specially tuned for real-time server-to-client communication.

Compatible with

🌟 Key Features

⚡ Works with native Redis Driver: Wave seamlessly integrates with Laravel's default redis broadcasting driver, ensuring efficient real-time data transfer.

🔄 Resume From Last: Connection drops? No problem! Wave intelligently resumes the event stream from the last event, ensuring no crucial data is lost in transit.

🟢 Live Models: With a simple interface that respects Laravel's native conventions for Model Events Broadcasting and Broadcast Notifications, Wave turbocharges your application with real-time updates.e

🍃 Resource-Friendly Broadcasting with pauseInactive: This feature maximizes resource efficiency by closing the data stream when user inactive ( such as when the user minimizes the browser) and automatically reopens it upon resumption of visibility. Turned off by default.

🎛️️ Full Requests Control: Wave hands you the reins over connection and authentication requests, granting you the freedom to shape your broadcasting setup to your exact requirements.

Installation

Laravel 11 or higher

Install the package via Composer at first, then install broadcasting setup:

composer require qruto/laravel-wave
php artisan install:broadcasting

Laravel 10 or lower

Install Wave on both server and client sides using Composer and npm:

composer require qruto/laravel-wave
npm install laravel-wave

Then, set your .env file to use the redis broadcasting driver:

BROADCAST_DRIVER = redis

Usage

After installing Wave, your server is ready to broadcast events. You can use it with Echo as usual or try Wave model API to work with predefined Eloquent events.

In Laravel 11 or higher, after install:broadcasting, you will find:

• broadcasting channel authorization file in routes/channels.php
• broadcasting configuration file in config/broadcasting.php
• echo instance in resources/echo.js
• (optional) Wave configuration file in config/wave.php

Manual usage

Import Laravel Echo with WaveConnector and pass it to the broadcaster option:

import Echo from 'laravel-echo';

import { WaveConnector } from 'laravel-wave';

window.Echo = new Echo({broadcaster: WaveConnector});

For Laravel 10 or lower, locate Echo connection configuration in resources/js/bootstrap.js file.

- import Echo from 'laravel-echo';

- import Pusher from 'pusher-js';
- window.Pusher = Pusher;

- window.Echo = new Echo({
-     broadcaster: 'pusher',
-     key: import.meta.env.VITE_PUSHER_APP_KEY,
-     wsHost: import.meta.env.VITE_PUSHER_HOST ?? `ws-${import.meta.env.VITE_PUSHER_APP_CLUSTER}.pusher.com`,
-     wsPort: import.meta.env.VITE_PUSHER_PORT ?? 80,
-     wssPort: import.meta.env.VITE_PUSHER_PORT ?? 443,
-     forceTLS: (import.meta.env.VITE_PUSHER_SCHEME ?? 'https') === 'https',
-     enabledTransports: ['ws', 'wss'],
- });
+ import Echo from 'laravel-echo';

+ import { WaveConnector } from 'laravel-wave';

+ window.Echo = new Echo({ broadcaster: WaveConnector });

Use Echo as you typically would.

Use Live Eloquent Models

With native conventions of Model Events Broadcasting and Broadcast Notifications you can use Wave models to receive model events and notifications.

import { Wave } from 'laravel-wave';

window.Wave = new Wave();

wave.model('User', '1')
    .notification('team.invite', (notification) => {
        console.log(notification);
    })
    .updated((user) => console.log('user updated', user))
    .deleted((user) => console.log('user deleted', user))
    .trashed((user) => console.log('user trashed', user))
    .restored((user) => console.log('user restored', user))
    .updated('Team', (team) => console.log('team updated', team));

Start by calling the model method on the Wave instance with the model name and key.

By default, Wave prefixes model names with App.Models namespace. You can customize this with the namespace option:

window.Wave = new Wave({namespace: 'App.Path.Models'});

    endpoint: '/sse-endpoint',
    bearerToken: 'bearer-token',
    //...
});

// or

new Wave({

Persistent Connection with Nginx + PHP FPM

Wave is designed to automatically reconnect after a request timeout. During reconnection, you won't lose any events because Wave stores event history for one minute by default and resumes it. You can adjust the duration of event history storage by modifying the resume_lifetime value in the config file.

However, if you want to maintain a persistent connection, let's configure your web server.

fastcgi_read_timeout

By default, the fastcgi_read_timeout value is 60s for Nginx + PHP FastCGI server setup.

Option 1. Without changing the fastcgi_read_timeout value

Ensure that the interval between events pushed into Wave connection is shorter than the read timeout value

To enhance the certainty of events occurring more frequently than the standard timeout, Wave attempts to send a ping event with each Server-Sent Events (SSE) connection request, provided that the previous event occurred prior to the ping.frequency configuration value.

If your application doesn't expect many real-time connections, specify the list of environments in which a ping event will be sent with each Wave connection. By default, this is set to local.

Option 2. Manual ping control

To ensure accurate frequency sending a ping event:

1. Disable automatic sending by changing the ping.enable config value to false
2. Use the sse:ping command to manually send a single ping or operate at an interval

Run the command with the --interval option to send a ping event at a specified interval in seconds, for example let's send a ping event every 30s:

php artisan sse:ping --interval=30

So, every 30s, the command will send a ping event to all active connections and ensure that the connection remains persistent, because the frequency of sending events is less than 60s.

Alternatively, use the Laravel Tasks scheduler to send a ping event every minute or more often if fastcgi_read_timeout value is greater than 60s:

protected function schedule(Schedule $schedule)
{
    $schedule->command('sse:ping')->everyMinute();
}

request_terminate_timeout

Some platforms, such as Laravel Forge, configure the PHP FPM pool with request_terminate_timeout = 60, terminating all requests after 60s.

You can disable this in the /etc/php/8.1/fpm/pool.d/www.conf config file:

request_terminate_timeout = 0

or you can configure a separate pool for the SSE connection.
