Open source websocket event handler
Pushman is an open source web socket event manager. It allows you to push events over HTTP to your own Pushman server which will push event information down to a client via a Web Socket.
You can bind server side events to client notifications.
Demo on the Pushman Website.
Okay, testing is the next big thing. Thanks to laravel 5.1, I'll write up tests in PHPUnit!
Documentation for usage can be found on the Pushman website.
Documentation for building your own Pushman instance is found below.
Pushman works fantastically on Laravel's Forge! You still need to install prerequisites though.
Pushman requires ZeroMQ which is a custom binary (Windows and Linux), along with it's PHP extension.
You can follow zmq's installation instructions, but you should know building it for a Forge server is easy.
When installing on Windows, you can just install the .exe from their website.
For Debian based systems, there is an apt package:
apt-get install libzmq3-dev
You can always build the PHP extension yourself:
git clone git://github.com/mkoppanen/php-zmq.git $ cd php-zmq phpize && ./configure $ sudo make $ sudo make installWhen building the extension for Windows, you can just download an existing .dll file from their website and place it in the php /ext directory. You will also need to add the
extension=zmq.dllto your php.ini file.
Pushman requires two ports to function, an
PUBLICport, the public port handles websocket connections and the other handles incoming API requests.
By default both of these ports are configurable in the
.envfile in the root directory or by setting an environment variable. You only need to setup a firewall rule for the
PUBLICport, but do ensure both ports are free to bind to.
On forge, you can just build a new site, and give the it the Github repo to install itself.
Duffleman/pushmanon the master branch is what you need to enter.
On a regular server, git clone the directory and run
composer install --no-devto install the requirements.
Pushman requires a database, so for both Forge and a regular server, enter your Database editor of choice, or sqlite, and build a database and enter the details in the
.envfile in the root web directory.
Once the database configuration is set, you can run
php artisan migratefollowed by
php artisan key:generateto publish the database layout. Or on Forge, just redeploy the site.
You MUST set an App Key.
You may also need to run
chmod -R 777 storage/to grant write permissions on your storage folder. You may also need to run
chmod -R 777 bootstrap/cacheto grant write permissions on the cache directory.
Pushman itself can then be run by using
php artisan pushman:run. I highly recommend setting up a supervisord task for this or in Forge, go into your server tab and enter the full path to artisan and Forge will auto monitor the task for you.
php /home/forge/pushman.dfl.mn/artisan pushman:run

Currently we use a TOKEN in the URL string to see if the user is authorized to connect. Could we find a better way to push data to the server, things like a unique ID identifying them as a user perhaps?
After that, we can allow an API to /api/listeners or something which returns the listeners of a channel, the events they listen to, and any of that data. Then we allow an API point for /api/whisper which broadcasts back to a specific user only.
