+BabelPlugin `Add module.exports`  [![NPM version][npm-image]][npm] [![Build Status][travis-image]][travis] [![Coverage Status][cover-image]][cover] [![Climate Status][climate-image]][climate]
+---
+
+> Fix [Kill CommonJS default export behaviour - babel/babel#2212](https://github.com/babel/babel/issues/2212)
+
+Installation
+---
+
+```bash
+npm install babel-plugin-add-module-exports --save-dev
+```
+
+Why?
+---
+
+[babel-plugin-transform-es2015-modules-commonjs@6.1.3](https://www.npmjs.com/package/babel-plugin-transform-es2015-modules-commonjs) doesn't support the `module.exports`.
+
+```js
+// index.js
+export default 'foo'
+```
+
+```bash
+npm install babel-core@6.1.2 --global
+npm install babel-preset-es2015 --save-dev
+npm install babel-plugin-transform-es2015-modules-commonjs --save-dev
+
+babel index.js --presets es2015 --plugins transform-es2015-modules-commonjs > bundle.js
+# 'use strict';
+#
+# Object.defineProperty(exports, "__esModule", {
+#   value: true
+# });
+# exports.default = 'foo';
+```
+
+Therefore, need to use the `.default` at NodeJS.
+
+```js
+require('./bundle.js') // { default: 'foo' }
+require('./bundle.js').default // 'foo'
+```
+
+This plugin add the `module.exports` to EOF.
+
+```bash
+npm install babel-plugin-add-module-exports --save-dev
+babel index.js --presets es2015 --plugins babel-plugin-add-module-exports > bundle.js
+# 'use strict';
+#
+# Object.defineProperty(exports, "__esModule", {
+#   value: true
+# });
+# exports.default = 'foo';
+# module.exports = exports.default;
+```
+
+Therefore, `.default` is the unnecessary.
+
+```js
+require('./bundle.js') // 'foo'
+```
