Server category rules

• Sandbox server

  • You can find the official sandbox server at https://github.com/js13kGames/js13kserver.

• Package size still below 13 kB

  • Game package will contain all the game code and assets, for the client and the server.

• Sandboxed environment

  • Your game will run in a node.js based sandbox environment. That means you will not really use node. You cannot require modules and your own modules shipped by your 13k pack.

• Do not leak the sandbox

  • This is not a hacking competition. This is a way to help the competition admins, the site persistence, and you. Do not touch the procfile and the index.js file.

• Socket.io client lib

  • You can use it. Simply add <script src="https://github.com/Cypher1/13k_lost/raw/master/socket.io/socket.io.js"></script> to your HTML and that will be loaded. No server configuration will be needed. The sandbox already did it.

• Can I test the sandbox before submitting?

  • Yes, you can and you must! Installing and getting it running is simple. Visit the project page at https://github.com/js13kGames/js13kserver.

• Is there any example? How do I develop my game using the sandbox server?

  • There's a simple "Rock, Paper, Scissors" example in the public folder.

• I have more questions!

  • Feel free to send them to server@js13kgames.com.
