MancJS: Code Golf

A code golf game server for JavaScript.

Running

• Clone the repo
• Install dependencies via npm install
• Set the CG_ADMIN_PASSWORD environment variable to secure access the the /admin page (see package.json start script)
• Start the server locally via npm start

URLs

/

The submission page where players can submit solutions to the current game. Players must enter an email address (used only to render gravatar images) and a team name.

/admin

The admin page for creating new games. Stopped games prevent new submissions and allow players to view other player submissions.

Security

The admin page is protected with HTTP basic auth. The username is admin and the password is the value of the CG_ADMIN_PASSWORD environment variable.

Notes

Changing the title of the game on the admin page and starting the game again will clear current entries and begin a new game. All other modifications update the current game.

Playing

Runtime

Node v16.14.0 with no context and strict mode enforced.

Submissions

Players must write a script containing their solution. The solution must be a single synchronous function named play. The exported function will be called by the game server on each submission. Example:

let play = (input) => {
  return 'your answer';
};

Players can submit updated solutions as often as they like on the submission page.

Rules

• Your solution must be a single synchronous function named play (don't worry about exporting it)
• Your code will be run in strict mode – use node's --use_strict flag to test your script
• All JavaScript language features available in Node.js v16.14.0 are available, with game-specific exceptions
• Scripts are timed-out and fail after 5 seconds of execution time
• Comments, line breaks and whitespace do not count towards your score (we run your code through jsmin 1.0.1 before taking the length)
• The aim is to solve the problem with the shortest possible code (fewest "strokes")
