WebAssembly is the magic sauce that transforms server-side code into client-side code. MySQL unfortunately is not yet supported by WebAssembly, so I applied a plugin that adds SQLite supports to WordPress [0]. The WebAssembly application has its own in-memory filesystem that lives in a specific browser tab and is scraped as soon as you close it.
So – technically it exposes db credentials, and even the entire DB, but that you are the only user of that DB so it's okay.
> What would the backend look like
The only backend is a static file server where the code and the database live. Your browser downloads a copy of the database and allows you to modify it in the current tab, but the updates are never saved back to the server.
