Nodb

By storing JSON items through the API you're actually building your own API, because when you store them (via POST request) you'll create URLs for fetching them as well. I would like someone to try to use it for their side projects and test it for production.
Let me know please your thoughts what you think about this project and what could it have added, adjusted or removed. I have plenty of ideas right now, like joining tables through query params.
