I am having an "Unexpected token export" issue in Webstorm that has not been solved by the other StackOverflow posts. Essentially I am trying to use the import/export module functionality with the package.json and bar.js code below. I am using Node.js 5x, Babel 6, and I have a File Watcher setup to do the Babel transforms on the fly.
The code should speak for itself, and I appreciate any thoughts on how to resolve it. Again, I have tried the other StackOverflow suggestions with no luck at this point.
//bar.js
'use strict';
export class Bar{
constructor(){
this.tempish = 'allo';
}
}
//bar-compiled.js
'use strict';
Object.defineProperty(exports, "__esModule", {
value: true
});
function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }
var Bar = exports.Bar = function Bar() {
_classCallCheck(this, Bar);
this.tempish = 'allo';
};
//# sourceMappingURL=bar-compiled.js.map
//index.js
'use strict';
import {Bar} from './bar'
console.log('This is a test.');
//index-compiled.js
'use strict';
var _bar = require('./bar');
console.log('This is a test.');
//# sourceMappingURL=index-compiled.js.map
//package.json

what does your index-compiled.js
code look like? seems it requires original bar.js
rather than bar-compiled.js
. Node.js can't natively execute ES6 code, thus the errors.
I'd recommend configuring the compiler to output transpiled code into a separate directory to avoid using 'compiled' postfix. Please see the following link for instructions on setting up Babel 6 with WebStorm: http://mcculloughwebservices.com/2015/12/10/webstorm-babel-6-plugin/
