Productive for both client and server apps. Instead of relative paths:

var env = require("../../../env")

Import relative to the project:

var env = require("_/env")

Install with github and npm:

$ npm install --save aj0strow/underlink

You can use it as a command, like in an npm postinstall script:

$ node_modules/.bin/underlink

For some platforms, like Heroku, it doesn't work. In that case:

require("underlink")("app")
