Hi, I'm migrating my app to a mono repo but I just can't get past this error for some reason Cannot access 't' before initialization when using the tRPC instance anywhere be it a middleware or router The server is a standalone node server useAuthenticaton.ts

import { TRPCError } from '@trpc/server'
import { t, User } from '../server/api'
import * as Auth from '../services/auth/auth'

const useAuthentication = t.middleware(async ({ ctx, next }) => {
  try {
    const authToken = ctx.req.headers['token'] as string
    const authResult = (await Auth.verifyJWTToken(authToken)) as User

    return next({
      ctx: {
        user: authResult
      }
    })
  } catch (error) {
    throw new TRPCError({
      code: 'UNAUTHORIZED'
    })
  }
})

export default useAuthentication

tRPC standalone server in monorepo

Hi, I'm using t3-stack monorepo as my base and I've swapped out NextJS backend for standalone HTTP server but I just can't get it work Discord wouldn't let me post the code as it was too long so I've uploaded the api.ts and client.ts along with the error to gist https://gist.github.com/neo773/7c8a314785d5e4f54c724cde7e5fa65c

Request context inside middleware?

Hi, Is it possible to get the request context inside a middleware somehow? I'm trying to migrate a Express Based API

const t = initTRPC.context<Context>().create();

const useAuthentication =  t.middleware(({ next, ctx }) => {
   const token = ctx.req.headers['authorization']
})

const t = initTRPC.context<Context>().create();

const useAuthentication =  t.middleware(({ next, ctx }) => {
   const token = ctx.req.headers['authorization']
})
