@munsterlander this is a very good question! I actually didn’t know that Web SQL was deprecated. At the moment, Monaca includes just Web SQL plugin but the native Cordova plugin can be imported with a developer or higher plan and should work without any issue. We will discuss about integrating the new plugin in Monaca but I cannot say when it will happen. I don’t think you will have any issue with Web SQL but, of course, it’s better to use the native plugin.
