babel-plugin-transform-es2015-modules-commonjs 6.24.0

v6.24.0

on Node.js NPM

6.24.0 (2017-03-13)

A quick release for 2 features:

• Thanks to @rwjblue, there is now a noInterop option for our es2015-modules transform to remove the interopRequireDefault and interopRequireWildcard helpers.

Input

import foo from "foo";
foo;

Regular Output

var _foo = require("foo");
var _foo2 = _interopRequireDefault(_foo);
function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }
_foo2.default;

Output with option noInterop

"use strict";
var _foo = require("foo");
(0, _foo.default)();

This also helps ember-cli migrate to Babel 6.

• @izaakschroeder has added dirname to the preset constructor which presets can use to resolve things relative to files.

Example usage of fileContext.dirname in a preset

module.exports = function preset (context, options, fileContext) {
  if (/resolve-addons-relative-to-file$/.test(fileContext.dirname)) {
    return {
      plugins: ['plugin-here'],
    };
  }
  return {};
};

This will help out with reusing a browserslist file for babel-preset-env and for plugins like https://github.com/tleunen/babel-plugin-module-resolver.
