JS Bundler

A Rust based toy bundler for Javascript For research purposes only, not production ready!

Currently performs a "webpack" style bundling process that condenses all modules into a single file that provides a module dictionary that grants each module a require and exports object.

ex. 
const modules = {
	"modA": (require, exports) => {...},
	"modB": (require, exports) => {...},
}

Handled Use Cases

• Transforms relative imports to require statements

ex.
import area from "../square" -> const { default: area} = require("../square");
import area, { anotherFn } from "../square" -> const { default: area, anotherFn} = require("../square");

• Transforms exports to module exports

export default area -> exports.default = area;
export const area = _area -> exports.area = _area;
export { area } -> exports.area = area;

• NodeJS modules imports

import express from "express"

• "Rollup" style bundling
• Bundle beautifier after generating
