babel-plugin-transform-es2015-modules-systemjs

This plugin transforms ES2015 modules to SystemJS.

Example

In

export default 42;

Out

System.register([], function (_export, _context) {
  return {
    setters: [],
    execute: function () {
      _export("default", 42);
    }
  };
});

For dynamic import support (import('./lazy.js').then(m => ...)), enable the syntax-dynamic-import plugin before this one.
