nodeHTTPHandler with Nitro

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

node-http

node-http

adapter.

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

undefined

.

I've also tried the

trpc-nuxt

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).

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

trpc-nuxt
