Installation

For Laravel 9-10:

For Laravel 11-12, there are specific instructions below.

Select the version you need

Version	PHP	Laravel	Centrifugo	Notes

`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 centrifuge:install command, which will publish the configuration file and generate the necessary environment variables in your .env file with default values.

php artisan centrifuge:install

Credentials

To establish a connection with Centrifugo, you need to provide credentials from your Centrifugo server's config.json file. Laravel will generate example keys that you should replace with your actual server credentials. 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
