CJS to ES6 Module

Convert a CJS module to an ES6 module.

• Unlike other package managers, all import stuff must occur at the top-level of the module.
• Does not support require()s in try/catch statements
• Does not support conditional require()s
• Does not support require()ing the same module multiple times
• Does not support code with its own require() functions or methods
• Does not fix extensions, which might be necessary for ES6 modules
• Probably only supports module MyModule from "cjs-module" syntax, not the import {stuff} from "cjs-module" syntax

API

es6js = convert(cjs)

var convert = require('cjs-to-module');
var js = convert(someCommonJSString);

The output will look something like:

module __0 from "events";
module __1 from "./local";

var __module = {};
(function (module, exports) {

})(__module, __module.exports = {});

export default __module.exports;
