Hello, is there any way to create a base router with common procedures? like an interface

I want all routers that use it have the state procedure (subscriptions), so I can create a common hook later Although the implementation of the methods is completely different on each router, I just want to guarantee that they have those procedures, like an interface The hook basically will subscribe to the state on mount, and unsubscribe on unmount Thanks

Review of inner and outer context with express

Hello, I didn't find any example that uses inner (for testing) and outer context with express. That's how I implemented it for my express trpc boilerplate, I wanted to know if I did it right, or if there was some error. Thank you so much TLDR; The inner context and options is a custom object with partial express options. the outer context and options is an extension of the inner but now the express options are mandatory.

In the context should I put all my dependencies for my endpoint handlers?

For example I have the end point 'getStuff` In this endpoint the handler call 3 party apis and map the data to the tRPC output. But I have an API key rotator class, to do each request to a 3 party API with the different API key in each request. So should I put in the context the API key rotator class? And this should be a singleton like the db instance? Also the API key rotator has dependency on the db, to store the last used API key, and consult all API keys. Thanks

is there a simple boilerplate that has everything ready to deploy?

For example nodemon, reading the port for .env, etc. (I don't know if that's how it is haha) I use turborepo, so can be an internal package. But I want to see how the project configuration looks for the deploy. It's the first time I am creating a server, for now it will be deployed on a PC on an intranet. It's just a server to everyone in the intranet can access and modify a json file. Thanks
