Cannot use angular in my datasource plugin

Hi allll,

I have defined some input elements in my HTML Now I want to access them with angular. As template I use the simple json plugin. I addes only this to my datasource.js
import angular from ‘angular’;

and in the query method:
var myApp = angular.module(‘myApp’, );

When I start build with grunt I see the following error:
Running “mochaTest:test” (mochaTest) task

Mocha exploded!
TypeError: Cannot read property ‘angular’ of undefined

Can anyone help? I searched the web but cannot find any helpfull information.
Thanks,
Hakan
