Any way I can `require` a file from the project’s folder?

I’m writing a project that uses WiFi and I’d like to publish it on github. However, I don’t want to publish my WiFi credentials. The way I’d usually solve this is by creating a settings file and putting it in .gitignore. In this case it would look something like this:

var WiFiCredentials = require('./wifi-credentials.js');

I also wrote some modules and I’d prefer to publish them alongside with the main project file rather than separately.

Is there any way I can require a local module not from the modules folder?
