Uncaught ReferenceError: module is not defined

as title says; error when including the JS file

Short answer
Use npm.

If not, try this in the Node.js REPL:

// assuming node (or node.exe) is run from the same directory as lunicode.js
var Lm;
limp = import('./lunicode.js');
limp.then((module) => {Lm = module.default;});

// Lm now has Lunicode powers
Lm.tools.mirror.encode('HEY BRVH'));

UPDATE: Just realised you can just assign exported stuff to variables in JS

If you like golf, here's my one-liner import statement:

import('./lunicode.js').then((m)=>{Lm=m.default;});

Note for those running into Cross-Origin Security Errors

If you're doing this in a browser, you might run into Cross-Origin security errors. There are ways around it, like 'setting up a local server' (MDN Web Docs). The restrictions are intended to prevent security incidents given how risky browsers (large attack surface + public WAN-facing) can be. I might create a Dockerfile to make things easier.

Long Answer

Lunicode.js was designed for use with npm's require(), which has some perks like dynamic async loading, but makes little try-at-home experiments more contrived. Importing lunicode.js doesn't help because of the way the Lunicode tools are exported:

module.exports = new Lunicode();

The actual Lunicode() function isn't exported, just its results. The results of this call would only work with a dynamic import, or npm's require().
