javascript - import class and call static method with es6 modules with babel transpiler

Question

I have the following class definition:

class EmberReflux{
  static createActions(actions) {
    console.log(actions);
  }
}

export { EmberReflux };

When I import it from a different file:

import EmberReflux from '../utils/ember-reflux';

let TodoActions = EmberReflux.createActions(
[
  "addItem",
  "undo",
  "redo"
]);

export { TodoActions };

The transpiled looks like this

define('ember-reflux/utils/todo-actions', ['exports', 'ember-reflux/utils/ember-reflux'], function (exports, EmberReflux) {

    'use strict';

    var TodoActions = EmberReflux['default'].createActions(["addItem", "undo", "redo"]);

    exports.TodoActions = TodoActions;

});

I'm not sure what the default is in EmberReflux['default']

I want to call the static class method like this:

EmberReflux.createActions

But instead I have to call it like this:

EmberReflux.EmberReflux.createActions

You have two options:

1. Export EmberReflux like you are doing:

   export { EmberReflux };
   

   and then import it like:

   import { EmberReflux } from '../utils/ember-reflux';
   

2. Use default when exporting:

   export default EmberReflux;
   

   and import it (like you are doing):

    import EmberReflux from '../utils/ember-reflux';
   

In both cases you can then use your EmberReflux like:

EmberReflux.createActions();
