TypeError: Cannot read property 'openDatabase' of undefined

Question

I want to work with sqlite with cordova framework for the first time. As I\'ve read on a tutorial I should use ngcordova like this:

var db = null;
app.contro

You might take a look at this tutorial:

https://www.thepolyglotdeveloper.com/2014/11/use-sqlite-instead-local-storage-ionic-framework/

When you see this error:

TypeError: Cannot read property 'openDatabase' of undefined

It is happening for one of a few reasons:

1. You are not wrapping the $cordovaSQLite methods in the $ionicPlatform.ready() function.
2. You are trying to test this native plugin from a web browser.
3. You have not actually installed the base SQLite plugin into your project.

The most common reasons for this error are #1 and #2. Native plugins, must be used only after the application is confirmed ready, thus the $ionicPlatform.ready() method. Since native plugins use native code, you cannot test them from your web browser.

Read through the tutorial I linked because it should help you.

Actually, I opened an old project and I get this error only when I run the project with -cls (because of liverelaod). But I have a small bug to fix there so I didn't investigate it too much(just fix it without livereload). But maybe this little hint helps somebody.
