Quick example of using SQLite with Ionic React. This was created using the blank Ionic starter app and the sample code on the SQLite plugin docs.
I've only used it with Android but iOS should work all the same.
Clone this repo then:
npm install
ionic cap open android
Plug in your device, run the app and tap the 'INIT DB' button.
Open Chrome, go to chrome://inspect and inspect the app to view the results in the JavaScript console.
To create the platform files from scratch, delete the ./android directory and generate the Android platform files.
rm -rf ./android
ionic cap add android
ionic cap sync
