nodeHTTPHandler with Nitro

I'm trying to setup trpc with nitro.unjs.io using the node-httpadapter.

import { nodeHTTPRequestHandler } from "@trpc/server/adapters/node-http";
import { appRouter } from "~/lib/trpc/router";

export default defineEventHandler(async (event) => {
    console.log('trpc route handler');
    const res = await nodeHTTPRequestHandler({
        req: event.node.req,
        res: event.node.res,
        router: appRouter,
        path: '/api/trpc',
    });
    console.log(res) // returns undefined
});

import { nodeHTTPRequestHandler } from "@trpc/server/adapters/node-http";
import { appRouter } from "~/lib/trpc/router";

export default defineEventHandler(async (event) => {
    console.log('trpc route handler');
    const res = await nodeHTTPRequestHandler({
        req: event.node.req,
        res: event.node.res,
        router: appRouter,
        path: '/api/trpc',
    });
    console.log(res) // returns undefined
});

Frontend setup:

    const [queryClient] = useState(() => new QueryClient());
    const [trpcClient] = useState(() => trpc.createClient({
        links: [
            httpBatchLink({
                url: 'http://localhost:3000/api/trpc',
            }),
        ],
    }));

    const [queryClient] = useState(() => new QueryClient());
    const [trpcClient] = useState(() => trpc.createClient({
        links: [
            httpBatchLink({
                url: 'http://localhost:3000/api/trpc',
            }),
        ],
    }));

const { data, isLoading } = trpc.formList.useQuery();

const { data, isLoading } = trpc.formList.useQuery();

There are no TS errors anywhere so the router setup should be correct. However the nodeHTTPRequestHandler function always returns undefined. I've also tried the trpc-nuxt package because apparently that's supposed to work with Nitro but I couldn't get it to work because I'm using trpc v11.

Solution:

Nvm, it seems to work like this. Have to return the correct response of course (which revealed another error with the path). ```ts export default defineEventHandler(async (event) => { console.log('trpc route handler');...

Nvm, it seems to work like this. Have to return the correct response of course (which revealed another error with the path).

export default defineEventHandler(async (event) => {
    console.log('trpc route handler');
    const res = await nodeHTTPRequestHandler({
        req: event.node.req,
        res: event.node.res,
        router: appRouter,
        path: getRequestURL(event).pathname.replace('/api/trpc/', ''),
    });
    return event.node.res;
});

export default defineEventHandler(async (event) => {
    console.log('trpc route handler');
    const res = await nodeHTTPRequestHandler({
        req: event.node.req,
        res: event.node.res,
        router: appRouter,
        path: getRequestURL(event).pathname.replace('/api/trpc/', ''),
    });
    return event.node.res;
});

No need for trpc-nuxt :POGGIES:
