How to integrate new modules

[Jortana]

If I write a module for user login, in what folder should I add it and how do I go about planning the dependent modules?

Same here.

Since nestjs have multiple modules, is there a good way to integrate tRPC with those modules' endpoint?

I saw from https://github.com/trpc/trpc/discussions/1504 seems that there have been a good way to do it?

And also somebody have wrote a adapter to do it https://github.com/macstr1k3r/trpc-nestjs-adapter
