Ionic + electron, how can I store my data?

Hello,
I need to dev an app crossplatform android(tablette)/Windows(PC). To do that I choose to use Ionic framework with Electron. My problem is about the storage of my data, I tryed to use sqlite but it doesn’t work with electron.
Error : (Native: tried accessing the SQLite plugin but Cordova is not available.).
This app needs to work offline without server, so I need to store data in local.

My question : How can I do that ?
With Json file maybe ? But Im not sure its a good idea.

Thanks !
