relative-fs
An NPM module that can wrap the fs module to make it's path arguments relative to the current directory.
Turns this:
var path = require('path');
var fs = require('fs');
var file = fs.readFileSync(path.join(__dirname, './some-file'));
Into this:
var fs = require('relative-fs').relativeTo(__dirname);
var file = fs.readFileSync('./some-file');
The plugin is very straight-forward and does exactly what you would think in just a few lines of code.
