Jsonjsdb - Client-side Relational Database

Jsonjsdb is a client-side relational database library specifically designed for static Single Page Applications. It enables offline data storage and querying capabilities, functioning effectively whether the application is run locally via the `file://` protocol or served over HTTP/HTTPS (e.g., localhost or production servers). The current stable JavaScript version is 0.8.10, with the project showing a somewhat active release cadence, although many recent updates have focused on its Python counterpart. A key differentiator is its unique approach to handling database file extensions (`.json.js` for `file://` and `.json` for `http(s)://`) based on the protocol, and its reliance on HTML-embedded configuration, which distinguishes it from more traditional pure JavaScript database solutions.
