Hallo,

i'm new to javascript and webstorm IDE.

I have a problem to get es6 running with ws.

I used this how to: http://mcculloughwebservices.com/2015/12/10/webstorm-babel-6-plugin/

test.js

my-module.js

If i run test.js i get:

"C:\Program Files (x86)\JetBrains\WebStorm 2016.1.1\bin\runnerw.exe" "C:\Program Files\nodejs\node.exe" test.js
d:\javascript\es6\src\test.js:5
import { cube, foo } from 'my-module';
^^^^^^

my-module.js.map

fileWatchter:

Okay how can i run the test.js without an error?

What are the *.map files for?

Thank you for any help.

The test.js in /dist folder looks like this:

'use strict';

var _myModule = require('my-module');

console.log((0, _myModule.cube)(3)); // 27
/**
 * Created by thilo on 15.05.2016.
 */

console.log(_myModule.foo); // 4.55580621596288

console.log(_myModule.foo); // 4.5558062159628555
console.log(_myModule.foo); // 4.5558062159628555

var square = function square(x) {
  return x * x;
};
//# sourceMappingURL=test.js.map

and the my-module.js is:

"use strict";

Object.defineProperty(exports, "__esModule", {
  value: true
});
exports.cube = cube;
/**
 * Created by thilo on 15.05.2016.
 */
// Modul "my-module.js"
function cube(x) {
  return x * x * x;
}
var foo = Math.PI + Math.SQRT2;
exports.foo = foo;


var square = function square(x) {
  return x * x;
};
//# sourceMappingURL=my-module.js.map

running this test.js i get this error:

"C:\Program Files (x86)\JetBrains\WebStorm 2016.1.1\bin\runnerw.exe" "C:\Program Files\nodejs\node.exe" test.js
module.js:327
throw err;
^

1. your first error occurs because you run original ES6 code (d:\javascript\es6\src\test.js) instead of the transpiled one (d:\javascript\es6\dist\test.js)

2. your next error is caused by the way you import your module. Try changing 'from 'my-module'' to 'from './my-module''
