Async User Call in `createContext` (context.ts) or in `isAuthed` (in trpc.ts)

Hi all! Should I be getting the user in all requests via createContext in the following async call

const { user } = await supabaseAdmin.auth.api.getUserByCookie(opts.req)

const { user } = await supabaseAdmin.auth.api.getUserByCookie(opts.req)

Or would it be more sensible for this to only be called in certain procedures such as middleware like isAuthed? In theory, I don't want public API calls being slower because of the delay it takes to fetch the user....

Mutations and Queries in React Contexts causing unexpected behaviors

In my organization, we recently moved to put all of our mutations/queries into React Contexts and out of components (NextJS with React 18). I am now seeing requests and debouncing behaviors that used to work no longer work.
In some cases it appears we now have race conditions as loading/success are not necessarily being handled, but in other cases we're not getting reactivity from mutations that are in contexts Anyone else have experience or tips re: throwing tRPC stuff into React Contexts?...

Custom error management

Hey peeps! I could've sworn I created a GitHub issue about this, but I must've been dreaming, because I cannot find it. Anyway, it's support-related, so I figured it's better to ask here! I have a large application that has a traditional client/server API and I use Axios to make calls to the server. Now, I'm investigating replacing that with tRPC (because it feels like an amazing developer experience and will quicken development). I have a rather "sophisticated" error management in the application. I have my own custom ApplicationError, which has an errorCode and a custom data object with additional information about the error. Any server-side code in the application can throw this error. A middleware catches this and converts it to a 400 Bad Request with an appropriate JSON response body. In the client, I also have my custom wrapper on top of Axios, that simply catches 400 Bad Request, and converts the JSON back to an ApplicationError and simply throws it. This means that I can easily catch ApplicationError in my client side code, just as if it was originally thrown on the client....

How can I generate trpc Generic Types?

I am building a trpc library, and as part of my implementation, I need the generic types of t, t.mergeRouters, t.procedure, t.router and t.middleware. I've haven't been able to locate those generic types in the @trpc/server and since trpc has such a complex type structure, would love to see an implementation for a generic set of types for the ones listed about....

context question

Why are the context examples only showing opinionated examples with next/react auth ? Also i find it very confusing that it is not mentioned in the docs what kind of arguments the context function is called with.

Is there a way to define the Websocket protocol when using wsLink()

I am attempting to use tRPC with Azure's Pub/Sub Websockets service it appears to require custom protocols to be defined as explained here: https://learn.microsoft.com/en-us/azure/azure-web-pubsub/reference-json-webpubsub-subprotocol They give the following code example: ```js var pubsub = new WebSocket('wss://test.webpubsub.azure.com/client/hubs/hub1', 'json.webpubsub.azure.v1');...

The inferred type of this node exceeds the maximum length the compiler will serialize.

Hey, there I am running into this error when I have more than 12 routers in the mergeRouters function.

The inferred type of this node exceeds the maximum length the compiler will serialize. An explicit type annotation is needed.
