Installs node_modules into temp directory and gives you access to them. This lets you avoid needing a node_modules folder.

	function installDeps(deps, quiet, cb) {
	const hash = require('crypto').createHash('md5').update(__filename).digest('hex')
	const dir = require('os').tmpdir() + require('path').sep + hash
	try {
	require('fs').mkdirSync(dir)
	if (!quiet) console.log(`Created temp folder at "${dir}"`)
	} catch (e) {}
	try {
	require('fs').writeFileSync(dir + require('path').sep + 'package.json', JSON.stringify({
	name: hash, description: hash, author: hash, repository: hash, license: "ISC",

luveti / require.js

Created September 19, 2016 17:12

A simple require function that: takes an array of urls, fetches the code using the Fetch API, then evals them using a wrapper that exposes module.exports to the code.

	function require (urls, cb) {
	if (!Array.isArray(urls) && typeof urls === 'string') urls = [urls];
	var modules = [];
	var i = 0, next = function () {
	fetch(urls[i])
	.then(function (response) {
	return response.text();
	})
	.then(function (code) {
	try {
