Install

composer require akbarali/nats-listener

After installing Nats Listener, publish its assets using the nats:install Artisan command:

php artisan nats:install

Configuration

After publishing Nats Listener's assets, its primary configuration file will be located at config/nats.php. This configuration file allows you to configure the queue worker options for your application. Each configuration option includes a description of its purpose, so be sure to thoroughly explore this file.

Running Nats Listener

Once you have configured your supervisors and workers in your application's config/nats.php configuration file, you may start Nats Listener using the nats:listener Artisan command. This single command will start all the configured worker processes for the current environment:

php artisan nats:listener

You may pause the Nats Listener process and instruct it to continue processing jobs using the nats:pause and nats:continue Artisan commands:

php artisan nats:pause

php artisan nats:continue

Deploying Nats Listener

When you're ready to deploy Nats Listener to your application's actual server, you should configure a process monitor to monitor the php artisan Nats Listener command and restart it if it exits unexpectedly. Don't worry, we'll discuss how to install a process monitor below. During your application's deployment process, you should instruct the Nats Listener process to terminate so that it will be restarted by your process monitor and receive your code changes:

php artisan nats:terminate

Supervisor Configuration

Supervisor configuration files are typically stored within your server's /etc/supervisor/conf.d directory. Within this directory, you may create any number of configuration files that instruct supervisor how your processes should be monitored. For example, let's create a nats.conf file that starts and monitors a nats listener process:

[program:nats_listener]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/artisan nats:listener
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
numprocs=1
user=forge
redirect_stderr=true
stdout_logfile=/var/www/supervisor/nats_listener_queue.log

Emotional Damage

I originally wrote this package because RabbitMQ was slow and had a lot of issues with our entire project. I thought NATS would be faster and more reliable. But in the end, it turned out that RabbitMQ is 25% faster.
