Babel Package Import

A way of structuring JS modules

Example

Package Structure

myApp
├── moduleA
│   └── index.js
├── moduleB
│   └── index.js
├── moduleC
│   └── index.js
└── index.js

In

import * as myApp from './myApp/*';

Out(ES6)

let myApp = {};
myApp['index'] = require('./myApp/index');
myApp['moduleA'] = {};
myApp['moduleA']['index'] = require('./myApp/moduleA/index');
myApp['moduleB'] = {};
myApp['moduleB']['index'] = require('./myApp/moduleB/index');
myApp['moduleC'] = {};
myApp['moduleC']['index'] = require('./myApp/moduleC/index');
 

Out(Raw)

use strict';
var _index = require('./myApp/index');
var $$_import_N1ebPFQ6qx = _interopRequireWildcard(_index);
var _index2 = require('./myApp/moduleA/index');
var $$_import_EJb_vtXT9l = _interopRequireWildcard(_index2);
var _index3 = require('./myApp/moduleB/index');
var $$_import_4yG_vtQ65l = _interopRequireWildcard(_index3);
var _index4 = require('./myApp/moduleC/index');
var $$_import_NJmbPFXa5g = _interopRequireWildcard(_index4);
 
function _interopRequireWildcard(obj) { if (obj && obj.__esModule) { return obj; } else { var newObj = {}; if (obj != null) { for (var key in obj) { if (Object.prototype.hasOwnProperty.call(obj, key)) newObj[key] = obj[key]; } } newObj.default = obj; return newObj; } }
 
var $$_export_VJZwKQT9l = {};
$$_export_VJZwKQT9l['index'] = $$_import_N1ebPFQ6qx;
$$_export_VJZwKQT9l['moduleA'] = {};
$$_export_VJZwKQT9l['moduleA']['index'] = $$_import_EJb_vtXT9l;
$$_export_VJZwKQT9l['moduleB'] = {};
$$_export_VJZwKQT9l['moduleB']['index'] = $$_import_4yG_vtQ65l;
$$_export_VJZwKQT9l['moduleC'] = {};
$$_export_VJZwKQT9l['moduleC']['index'] = $$_import_NJmbPFXa5g;
var myApp = $$_export_VJZwKQT9l;

Usage

Via .babelrc (Recommended)

.babelrc

{
  "plugins": ["babel-package-import"]
}

Via CLI

$ babel --plugins babel-package-import script.js

Via Node API

import { transform } from 'babel-core';
transform('code', {
  plugins: ['babel-package-import']
});

Installation

npm install --save-dev babel-package-import

Import Cache

Babel Package Import will cache modules which has been imported for every file.

Example

In

import * as myApp from './myApp/*';
import myApp2, { index as indexJS, moduleA } from './myApp/*';
 

Out(Raw)

'use strict';
var _index = require('./myApp/index');
var $$_import_4ygTNmf9qx = _interopRequireWildcard(_index);
var _index2 = require('./myApp/moduleA/index');
var $$_import_4J_TNXM55e = _interopRequireWildcard(_index2);
var _index3 = require('./myApp/moduleB/index');
var $$_import_NkzTEmzq9e = _interopRequireWildcard(_index3);
var _index4 = require('./myApp/moduleC/index');
var $$_import_4JXpEmG99e = _interopRequireWildcard(_index4);
 
function _interopRequireWildcard(obj) { if (obj && obj.__esModule) { return obj; } else { var newObj = {}; if (obj != null) { for (var key in obj) { if (Object.prototype.hasOwnProperty.call(obj, key)) newObj[key] = obj[key]; } } newObj.default = obj; return newObj; } }
 
var $$_export_EyaEmM5qx = {};
$$_export_EyaEmM5qx['index'] = $$_import_4ygTNmf9qx;
$$_export_EyaEmM5qx['moduleA'] = {};
