Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including up2require with all npm packages installed. Try it out:

var up2require = require("up2require")

all documents on RunKit are public
require() any package directly from npm
use arrow functions, classes, template strings, and most of ES6
await any promise instead of using callbacks (example)
create your own embedded node.js snippets

up2require v1.3.0

Upgrade-to-Update for the nodejs require() function. It replaces with and/or adds to the normal require way(s) to refresh functions imported with require(module). Function upgradeToUpdate(require) provided by this module returns the replacement function watchfulRequire(module, reloadUpdated) which has the option to clear require.cache for selected modules when they are updated and return wrappers for the imported functions. Those wrappers reload modules each time those are updated.
