With CodePen Projects you have a web IDE right in your browser, with preprocessing built-in. But what about installing dependencies via the
npm ecosystem? With some minimal effort it’s possible:
All you need to do is make a folder called
node_modules, and then inside of that make a file named after the module (e.g.
react.js) with the module’s code.
├── my-project.js └── node_modules └── react.js └── react-dom.js
From then on you can just import the libraries as you would normally do:
// my-project.js import React from 'react'; …
