Laravel + Centrifugo

Centrifugo broadcast driver for Laravel 9 - 11

Introduction

Centrifugo broadcaster for Laravel is based on:

• centrifugal/phpcent

Features

• Compatibility with the latest version of Centrifugo v5.4.6 🚀
• Wrapper for Centrifugo HTTP API 🔌
• JWT token authentication (HMAC algorithm) for anonymous, authorized users, and private channels 🗝️

Requirements

• PHP 8.0 - 8.3
• Laravel 9 - 11
• Guzzlehttp/Guzzle 6 - 7
• Centrifugo Server v5 or newer (see here)

Installation

For Laravel 9-10:

composer require denis660/laravel-centrifugo

For Laravel 11, there are specific instructions below.

Выберите нужную вам версию

Version	PHP	Laravel	Centrifugo	Notes
5.0.*	>= 8.0	9 - 11	5	Current version
3.0.*	>= 7.4	8.75.* - 10	4-5	Previous version

By default, broadcasting is disabled in new Laravel 11 applications. You can enable broadcasting using the install Artisan command:

php artisan install:broadcasting

If asked whether to install Reverb, answer “no.”

Then, install the package for working with Centrifugo via composer by running the following command:

composer require denis660/laravel-centrifugo

Configuration

Run the command centrifuge , which will install centrifuge-laravel with a reasonable set of default configuration options and generate default keys. If you want to make any changes to the configuration, you can update the environment variables in the .env file.

php artisan centrifuge:install

Credentials

To establish a connection with Centrifugo, you need to provide a set of Centrifugo credentials from the config.json file. These credentials are configured on the Centrifugo server, but Laravel will generate example keys that you should replace. You can specify these credentials with the following environment variables:

Required parameters:

CENTRIFUGO_TOKEN_HMAC_SECRET_KEY=token_hmac_secret_key-from-centrifugo-config
CENTRIFUGO_API_KEY=api_key-from-centrifugo-config

Optional parameters, modify if needed:

CENTRIFUGO_URL=http://localhost:8000
CENTRIFUGO_SSL_KEY=/etc/ssl/some.pem
CENTRIFUGO_VERIFY=false

Make sure to check the BROADCAST_DRIVER parameter in the .env file:

BROADCAST_DRIVER=centrifugo

        // Generate a connection token
        $token = $centrifugo->generateConnectionToken((string)Auth::id(), 0, [
            'name' => Auth::user()->name,
        ]);

        // Generate a token for a private channel connection
        $apiSign = $centrifugo->generatePrivateChannelToken((string)Auth::id(), 'channel', time() + 5 * 60, [
            'name' => Auth::user()->name,
        ]);
