#jsdroid#

Code evaluation bot for IRC.

• Code is run in a Docker container to hinder tampering
• When relevant, console logs and return values are returned separately
• Output is sanitized and long results are pasted and linked
• Currently supports JavaScript

###JavaScript###

JavaScript is evaluated using Node middleware that sandboxes the code to limit available methods. The middleware also summarizes the result to include e.g. the type of the return value. It makes available popular libraries like lodash, Moment.js and Math.js. The Dockerfile and middleware is installed as a dependency and can be found in node_modules/jsdroid-node/, where it can be built with Docker as follows:

docker build -t jsdroid-node .

The middleware can be modified before building the image to remove default libraries or install and include new ones. This does not require jsdroid to be restarted; the bot will immediately start using the new image. To remove the old image first and prevent a graveyard of unused images, run docker rmi -f jsdroid-node before building.
