WebSocket Echo Server

This is a simple WebSocket echo server written in Node.js. When the server receives a message, that message is sent to all connected clients.

This was originally designed as a server reference for simple multiplayer games for a Flash game development summer camp at the University of Calgary and was intended to be hosted on Heroku's free tier.

Configuration

• The server utilizes the PORT environment variable as the port, and defaults to 8080.
• To enable the keep-alive feature for running on Heroku or other platforms that allows inactive apps to sleep, set KEEP_ALIVE to true and set the URL environment variable to point towards your app.

Running the Server

node run start
