Web apps like notion,coda,airtable bring new dynamics to spreadsheet database, but most of them are backed up with back-end database,primarily online first and only allow for import and export, for local copy.
What is the best direction to building similar product but limited scope(ie small feature) and most importantly off-line first using file based storage as database, like excel, since am a programmer interact with file storage using sql like abstraction but allow for large dataset.
Basically off-line excel using web technology(react + electron ) but without bundling a database for the app to work, and off-line 90% of the time, thus using file as storage, but program interact with file using a sql abstraction. in future add express server for collaboration.
thanks for the help, this is for insurance company i work at, in Africa, so off-line is crucial.
