Changes

Currently the content server address (content.quakejs.com) is hard coded into the compile compiled ioq3 code. Because QuakeJS is so old, the version of Empscripten used to compile it is no longer available. I'm working on figuring out how to recompile the program. In the meantime, the easiest hack (and it is a hack) I've found to be able to run a local QuakeJS server, without an internet connection, is to edit your hosts file to redirect content.quakejs.com to your localhost. The below instructions will explain how to do this.
