Puggernaut
Simple server push implementation using eventmachine and long polling.
Requirements
gem install puggernaut
How it works
Puggernaut consists of four pieces:
- TCP client to send push messages
- TCP server to receive push messages
- TCP server to deliver messages via WebSockets (em-websocket)
- HTTP server to deliver messages via long poll
Start it up
Run the puggernaut
binary with optional port numbers:
puggernaut <http port> <tcp port> <tcp port (websocket)>
The default HTTP and TCP ports are 8100, 8101, and 8102, respectively.
Set up proxy pass
Set up a URL on your public facing web server that points to the Puggernaut HTTP server (long poll).
We all use Nginx, right?
nginx.conf
server { location /long_poll { proxy_pass http://localhost:8100/; } }
Send push messages
require 'puggernaut' client = Puggernaut::Client.new("localhost:8101", "localhost:9101") client.push :channel => "message" client.push :channel => [ "message 1", "message 2" ], :channel_2 => "message"
The Client.new
initializer accepts any number of TCP server addresses.
Receive push messages
Include jQuery and puggernaut.js into to your HTML page.
Javascript client example:
Puggernaut.path = '/long_poll'; // (default long poll path) Puggernaut.port = 8102; // (default WebSocket port) Puggernaut .watch('channel', function(e, message) { // do something with message }) .watch('channel_2', function(e, message) { // do something with message }); Puggernaut.unwatch('channel');
Running specs
Specs are a work in progress, though we can vouch for some of the functionality :).
Set up Nginx to point to a cloned copy of this project:
nginx.conf
server { listen 80; server_name localhost; root /Users/me/puggernaut/public; passenger_enabled on; location /long_poll { proxy_pass http://localhost:8100/; } }
You have now set up an instance of Puggernaut's spec server.
Start up an instance of Puggernaut by running bin/puggernaut
.
When you visit http://localhost
you will find a page that executes QUnit specs.
