npm install font
var font = require('font');
// get an array of fonts from the OS's font directory
font.listFonts();
// loads a file from either the font directory or a full path
font.loadFont('filename.ttf')
// the constructor and prototype
font.FontIt's currently very much not done but here's what you get so far:
