LGTM, just merge this when you're ready

I am not sure why I expected export default './bin/sqlite3-bundler-friendly.mjs'; to export the module and not a literal ./bin/sqlite3-bundler-friendly.mjs string, but that's what I get for trying to multitask during meetings 😆

We should be good now, I'm running the example we have and it's fully typed 😄

Small change I've added, that doesn't affect backwards compatibility is for await promiser('config-get'); to not require a second argument. Previously, we had to provide either {} or undefined, it should work without it now 😄

@tomayac, just so you're aware, I don't have write privileges, so I can't merge it :(
