babel-plugin-transform-import-commonjs

Fork of https://github.com/kiurchv/babel-plugin-transform-system-import-commonjs that compiles import instead of System.import, now that the import() proposal has been accepted.

Babel plugin that transforms ES2015 import into CommonJS require.

https://github.com/tc39/proposal-dynamic-import

How this works

This plugin transforms

var myModule = "./path/to/myModule";
 
import(myModule).then(function (module) {
  console.log(module);
});

to

var myModule = "./path/to/myModule";
 
new Promise(function(resolve) {
  resolve(require(myModule));
}.bind(this)).then(function (module) {
  console.log(module);
});

Requirements

You need support for Promise, use polyfill if needed.
