Uncaught (in promise): cordova_not_available in Ionic 2

You are accessing native plugins while testing in the browser. In order to make plugins work, you should use a real device to test.

In order to make your code testable in browser (or actually don’t break when testing in browser) you should have an if-statement checking if Cordova is available :

  if (this.platform.is('cordova')) {
    // You're on a device, call the native plugins. Example: 
    //
    // var url: string = '';
    // 
    // Camera.getPicture().then((fileUri) => url = fileUri);
  } else {
    // You're testing in browser, do nothing or mock the plugins' behaviour.
    //
    // var url: string = 'assets/mock-images/image.jpg';
  }

EDIT:

As Ricky Levi correctly mentions here below, Ionic supports the browser platform. Using this platform, most common plugins are able to work. Note that some plugins would not, for example the Barcode-scanner plugin. As it will prompt you with an alert, asking for the value that has to be scanned. Which will lose the whole use-case of a Barcode Scanner.
