Deno Babel Demo

What is this?

This project is a proof-of-concept running Babel to transpile code in the Deno runtime.

How do I try it?

1. Clone this repo, e.g.

   git clone https://github.com/davidbailey00/deno-babel-demo
   cd deno-babel-demo

2. Run npm install

3. Run npm run demo (or deno -A loader.js ./demos/babel)

How does it work?

Deno has a semi-complete Node.js compatibility library, and in addition, some Node.js standard packages have been ported to browsers and published to NPM (e.g. assert and util, both of which are used in this demo). By using these as polyfills, we can emulate a substantial amount of the Node.js environment.

Some files also need to be patched in cases where part of the Node.js standard library hasn't yet been ported to Deno, and/or where the behaviour is subtly different - have a look at scripts/patch-modules.js to see the patches.
