Phusion Passenger: Node.js WebSocket demo

This application demonstrates WebSocket support in the Phusion Passenger application server for Node.js, through the use of the awesome Socket.io library. Passenger supports all major modern web technologies, such as WebSockets, entirely out of the box. You don't have to do anything: WebSocket support just works.

Getting started

Preparations

  1. Install Phusion Passenger 4.0.45 or later.

  2. Clone this repository:

    git clone https://github.com/phusion/passenger-nodejs-websocket-demo.git
    cd passenger-nodejs-websocket-demo
    
  3. Install dependencies:

    npm install
    

Running the demo in Passenger Standalone

Run:

passenger start --sticky-sessions

Access the demo application at http://0.0.0.0:3000/ and see it in action.

Sticky sessions are required for long polling support.

Running the demo in Passenger for Nginx

Create a virtual host in your Nginx configuration file:

server {
    listen 3000;
    server_name passenger-nodejs-websocket.demo;
    root /path-to/passenger-nodejs-websocket-demo/public;
    passenger_enabled on;

    # Sticky sessions are required for long polling support!
    passenger_sticky_sessions on;
}

Add passenger-nodejs-websocket.demo to your /etc/hosts:

echo 127.0.0.1 passenger-nodejs-websocket.demo | sudo tee -a /etc/hosts

Then restart Nginx, and access the demo application at http://passenger-nodejs-websocket.demo:3000/

Running the demo in Passenger for Apache

Phusion Passenger currently does not support WebSockets on Apache. Having said that, Socket.io gracefully falls back to long polling when run on Apache, so the demo still works.

Create a virtual host in your Apache configuration file:

# Comment out if you already have a "Listen 3000" directive somewhere.
Listen 3000
# Comment out when using Apache >= 2.4.
NameVirtualHost *:3000

<VirtualHost *:3000>
    ServerName passenger-nodejs-websocket.demo
    DocumentRoot /path-to/passenger-nodejs-websocket-demo/public

    # Sticky sessions are required for long polling support!
    PassengerStickySessions on
</VirtualHost>

Add passenger-nodejs-websocket.demo to your /etc/hosts:

echo 127.0.0.1 passenger-nodejs-websocket.demo | sudo tee -a /etc/hosts

Then restart Apache, and access the demo application at http://passenger-nodejs-websocket.demo:3000/

Running the demo in Node.js without Passenger

Run:

node app.js

Then access the demo application at http://0.0.0.0:3000/
