babel-plugin-transform-system-import-commonjs v1.0.3

babel-plugin-transform-system-import-commonjs

Babel plugin that transforms ES2015 System.import into CommonJS require.

Deprecation notice

Since import() proposal was accepted, System.import function now is obsolete and this plugin is not recommended to use in new projects. Please use import() function with babel-plugin-transform-import-commonjs instead.

How this works

This plugin transforms

var myModule = "./path/to/myModule";

System.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.
