What's the benefit of using the context instead of a direct import for the database connection?

I've wondered why I should use the tRPC context instead of just importing my database singleton from a module. Is there any benefit to it? Because of TS performance issues, I'm creating multiple functions for bigger procedures. And passing the db connection around may be an unnecessary overhead.

i think people are doing it so they don’t have to import it everytime which is trivial to me. curious others people thoughts

Personally I import it where I use it I used to have it in the context so I think it caught on I don't think singletons belong there unless they're tied to some specific authed proc or similar

Thanks for the insights. Yeah, I find importing it way simpler, since VS Code just does it for me. But passing the context to each function is really annoying 😅 I wonder why the docs take the database connection as an example, while e.g. a user's profile is potentially different for each request.

If you want to unit test your work, it makes injecting mocks much easier It’s very much a best practice in other ecosystems Obviously in JS land we can mock modules, so a bit of personal preference exists

Yeah, sometimes we are a bit spoiled here in JS land. (Or almost going crazy because there's so many ways to do any given thing)
