type issue on router

[moreorover]

pnpm create better-t-stack@latest tanstack-check --frontend tanstack-router --backend hono --runtime node --api trpc --auth better-auth --payments none --database postgres --orm drizzle --db-setup docker --package-manager pnpm --git --web-deploy none --server-deploy none --no-install --addons biome turborepo --examples todo

both WebStorm and VSCode show same error. Application works fine otherwise.

TS2742: The inferred type of todoRouter cannot be named without a reference to .pnpm/@types+pg@8.15.5/node_modules/@types/pg. This is likely not portable. A type annotation is necessary.

I can reproduce this but not sure whats the solution 🤔

Can you try building the app pnpm run build type errors should go away! 🤔

The error is with the router() function’s return type — Drizzle’s row types are leaking pg internals into the inferred type.

You can confirm this by returning just a plain string — the error disappears.

import { db } from "@tanstack-check/db";
import { todo } from "@tanstack-check/db/schema/todo";
import z from "zod";
import { publicProcedure, router } from "../index";

export const todoRouter = router({
	getAll: publicProcedure.query(async () => {
		return await db.select().from(todo);
	}),

	create: publicProcedure
		.input(z.object({ text: z.string().min(1) }))
		.mutation(async ({ input }) => {
			return "";
		}),

	toggle: publicProcedure
		.input(z.object({ id: z.number(), completed: z.boolean() }))
		.mutation(async ({ input }) => {
			return "";
		}),

	delete: publicProcedure
		.input(z.object({ id: z.number() }))
		.mutation(async ({ input }) => {
			return ""
		}),
});

after building the project the error goes away, but really its a little annoying to have an error out of the box

@AmanVarshney01 this should be related to the way exports in package.json are configured for packages.
You reference ./dist for the DTS files but In development this causes issues.
