babel-plugin-transform-es2015-modules-simple-umd

Limited transformer for ECMAScript 2015 modules (UMD)

Converts this code:

import x from '/path/to/x';
import y from '/path/to/y';
import from '/path/to/z';
doSomething();
export default x + y;

Into this one:

(function (root, factory) {
  if (typeof define === 'function' && define.amd) {
    define(['/path/to/x', '/path/to/y'], factory);  
  } else if (typeof module === 'object' && module.exports) {
    require('/path/to/z');
    module.exports = factory(require('/path/to/x'), require('/path/to/y'));
  } else {
    root.returnExports = factory(root.x, root.y);
  }
})(this, function (x, y) {
  doSomething();
  return x + y;
});

Supported features:

• import SPECIFIER from 'PATH'
• import 'PATH'
• import {SPECIFIER1, SPECIFIER2 as SPECIFIER3} from 'PATH' but not as well as the AMD version. It's difficult to translate to a global variable.
• export default NODE

Other features aren't supported.

Warning. If no import or export are presented in JavaScript file, the plugin does nothing (means it doesn't wrap code with define).
