Is it possible to use local SQLite3 file with FileSystemAPI and WebAssembly in a web app?

Considering that:

• Browser's File System API enables web apps to write on local files, without subsequent asks for permissions.
• WebAssembly can run a native SQLite3 client.

It's possible to create a web app that asks for a local SQLite3 file and give WebAssembly client access to it? For example, to create a full-static "SQLite3 administrator" web app.

I want to start an open source project like this (React+Go+WebAssembly), as a proof of concept, but I don't know if these APIs support that.

Thanks!

This use case is exactly what the Storage Foundation API proposal was created for. You can test this API in Chrome by setting the #experimental-web-platform-features flag. If you run into any trouble, please file a new Issue in the GitHub repository.
