I did this once. A client wanted a website that mimicked the functionality of a complicated spreadsheet that he had created to calculate quotes for customers and didn't have enough money to pay to have all the logic rewritten in a webserver (not to mention continually updated).
I imported the spreadsheet into google sheets, gave him access, and had the webserver paste the values in the spreadsheet via the google sheets api and read them back out.
Not to detract from this project, buy this is a good opportunity to mention Apps Script.
You can do all sorts of interesting things between a form, spreadsheet, and other services including your own. Nobody seems to use it, but internally we do all sorts of gloriously hacky workflows with it.
You can easily script forms/sheets/calendar/Gmail together to create pretty much anything you need.
I use it to send daily email reports of data fed into a spreadsheet.
Ah sure, no problem, feel free to do a PR mentioning App Scripts as well if you'd like.
From a quick overview it seems like if you need serious work with spreadsheets/GDocs then App Scripts is a good choice. However drive-db is more like a (very) quick way of putting a Spreadsheet into your Node.js backend as an array/db. I purposefully didn't even allow edit since that'd require API keys from users and defeat the quick part of it.
