Subscription for a specific user

How can I create a TRPC subscription that takes a userId? When updates occur elsewhere in my app, I want to broadcast them to relevant users. Trying to avoid a full Socket.io rooms implementation

How to get the type of context after middleware context extension?

I have a middleware where I validate and set a userId. My router knows that userId is no longer undefined, but I need to pass the route context to another function. How do I set the input type for that function such that userId is no longer undefined?

Efficient way to use tRPC client with auth headers from secure storage

Wondering if anyone has a recommended pattern on caching the deviceId / authHeader using a React Context instead of fetching it async on each request. Thanks!

export const trpc = createTRPCClient<AppRouter>({
  links: [
    httpBatchLink({
      url: getServerUrl(),
      async headers() {
        const authorization = await getAuthHeader()
        const deviceId = await createOrGetDeviceIdFromStore()
        return {
          authorization,
          'x-device-id': deviceId,
        }
      }
    })
  ]
})
