`$ rucksack`

Bundle js files by replacing the require calls in-place.

Note: The current version is not really production ready. It does work for my use-cases, but it should be improved by parsing the real tree. Check out the falafel branch. Contributions in this direction are really welcome! 💖

console.log(rucksack(`${__dirname}/math.js`, "Math"));
// => 
// "use strict"; 
// (function() { 
//     var _rucksackModule = typeof module !== "undefined" ? module : {}; 
//     const sum = (a, b) => a + b; 
//     const square = x => x * x;
