For my Node application, I have a server (app.js) running on Debian serving both html and websocket data using socket.io to my client (index.html). I am attempting to make a turn-based HTML5 multiplayer game.
After performing a number of successful data transmissions using socket.emit()/io.emit() and socket.on(), my server crashes on an socket.emit() call with the error
events.js:72
throw er; //Unhandled 'error' event
RangeError: Maximum call stack size exceeded.
I have quite a few socket.on() event listeners, with each one handling a different function in the game (e.g. roll_dice, end_turn, ready_to_play, etc.).
I attempted researching the problem (found a lot of discussion on async loops), but was unable to find how to apply the solutions to my own code. I attached relevant source here. You can also view all the source on my github at: https://github.com/sjmoon0/gameofdeath
