Oogle Sign-In, Google Drive and Sync with Ionic webapp

I’m trying to create an Ionic app where I can use the Google Sign-In feature and Google drive files to sync with a web version of my app.

I want my app to share the users preferences and details through a file(json) stored on google drive. So the user will log on the site, make some changes, log on the app and receive those changes.

I’m here to ask your guidance on my problem, cause I don’t know if this is the best way to do it. Should I keep trying and implement this solution or try another approach?

Thanks for your comments!

I’m using Ionic2 and Angular 4.
