Prevent client tsc from typechecking the server
Hello,
I'm trying to use trpc as documented here, but as soon as I put
import type { AppRouter } from "../../src/index.ts"; the tsc for the browser client tries to check the node server and throws errors like
```...Skew protection Vercel TRPC
Was wondering if I can enable vercel skew protection for trpc.
According to docs, adding the dpl query should enable it.

Infer TRoot and TProcedure for specific procedures (polymorphism)
Hello!
I'm trying to build a custom hook that returns specific procedures of a router:

Hey, I only recently got to know trpc in connection with create-t3-app.
Now I have the question, can I use it everywhere or is it only possible in connection with web frameworks?
Would be very nice if you could enlighten me a bit 🙂...
Why Trpc duplicates `shape` and `data` as duplicated JSON field on errors in `errorFormatter`?
I am using error formater and internally TRPC duplicates the data information in the JSON response. Please see the screenshot

I have a problem with the procedure output type. Procedure input types are all correct, but the output type is "any."
The server type is correct, but not on

tRPC 404 in Next.js API Routes
I'm trying to upgrade my Next.js version to 15 and still use tRPC with API route. I'm getting 404 for all trpc api routes. Is anyone else facing the same issue? All the other api routes are working fine.

Hey tRPC community!
I'm working on a monorepo with a standalone tRPC server, a React Native app, and a Next.js app. Both frontend apps share a lot of common logic, particularly custom React hooks that wrap tRPC calls.
Currently, my proposed solution is to create shared hooks that require a React context providing the tRPC client. This approach allows each app to instantiate its own tRPC client (both based on the same AppRouter) while maintaining shared logic....
Prefetch using Next App router not working with useQuery but works with useSuspenseQuery
1. I'm not using the next adapter
2. I'm using the Next App Router
3. Using useSuspenseQuery works as expected, the query doesnt run onMount because it was prefetched, but it always runs using useQuery

tRPC Client Bundling `node_modules`
Hey team, I've been having an issue recently where tRPC seems to be bundling a
.pnpm and node_modules in @trpc/client. This is causing a lot of errors as I'm not using pnpm:
<project>/node_modules/@trpc/client/dist/TRPCClientError.mjs

createContext() function is defined with the FetchCreateContextFnOptions parameter signature, how do you fill that information out when using server side api calls, for example via createCaller? The example in the docs is inaccurate in that it defines a createContext function to require some parameters:
export const createContext = async (opts: CreateNextContextOptions) => { ... }
export const createContext = async (opts: CreateNextContextOptions) => { ... }
Trigger.dev
Is anyone here running tRPC procedures on Trigger.dev v3? I used tRPC just fine on V2, but since V3 code runs in their servers, it's throwing fetch failed errors.
