Taffy integration with Google Sheets?

[gerfnitauthor]

I just "finished" a Javascript project that uses a Google Sheet as persistent storage for my data. Currently, the app is read-only for search, but I know I'll need to add update capability eventually. How difficult would it be to develop an extension so that Taffy would load from a Google Sheet, allow search and modification like it already does, and then send only the updated records/rows back to the Google Sheet when the database was "closed" (as opposed to the whole thing)?
