@good-ghosting/random-name-generator/src/generator.js

Generate a random, unique, heroku-like name for your app/project/server etc. e.g. "resonant-silence". Extends the original package from Akash Kurdekar (git://github.com/aceakash/project-name-generator.git) by allowing custom adjectives and nouns.

const _ = require('lodash');
const nouns = require('./nouns');
const adjectives = require('./adjectives');
