nextjs app router + nodejs not working

[rengechan]

What version of Hono are you using?

4.2.1

What runtime/platform is your app running on?

nodejs

What steps can reproduce the bug?

    "next": "14.1.4",
    "@hono/node-server": "^1.9.1",
    "hono": "^4.2.1",

src\app\api\[[...route]]\route.ts

import { Hono } from 'hono';
import { handle } from '@hono/node-server/vercel';

const app = new Hono().basePath('/api');

app.get('/hello', (c) => {
  return c.json({
    message: 'Hello from Hono!',
  });
});

// export const GET = handle(app);
export default handle(app);

with export const GET = handle(app);

error

Hi @rengechan

Hmm. I've tried, but I can't reproduce it. Could you share a minimal project to reproduce it?

[alexandrefuente]

@rengechan, I had the same issue, I was looking for some solution, I have changed the line

import { handle } from '@hono/node-server/vercel'; to import { handle } from 'hono/vercel';

import { Hono } from 'hono';
import { handle } from 'hono/vercel';

const app = new Hono().basePath('/api');

app.get('/hono/:name', async (c) => {
  return c.json({
    message: 'Just a config of Hono backend side GET!'
  });
})

app.post('/hono', async (c) => {
  return c.json({
    message: 'Just a config of Hono backend side POST!'
  });
})

export const GET = handle(app);
export const POST = handle(app);
export default app as never;

Now it is working, but in the terminal still the message. Detected default export in '/src/app/api/[...slug]/route.ts'. Export a named export for each HTTP method instead.

I'm working on a client and service gateway project using vite-dev-server plugin and ran into this issue, but it only happens when I run the vite dev server in a docker container (my preferred workflow).

To reproduce, you can clone the repo and bring up the dev container with compose:

git clone git@github.com:stabledata/surface.git
cd surface
docker-compose up dev

This outputs:

[+] Running 1/0
 ✔ Container surface-dev-1  Created                                                                             0.0s

surface-dev-1  | Expected a Response object

Note the line after the vite command Failed to find Response internal state key. When you view http://localhost:4000 in a browser you see the Bun default page Get started by returning a [Response](https://developer.mozilla.org/en-US/docs/Web/API/Response) object in fetch(request)

Everything works perfectly fine on the local machine when running bun dev.

Not a huge blocker, I prefer to work in docker-compose but saw someone else reported the error and thought since I had an easy repro would post here.

Thanks for all the work on Hono! As a previous express user love the API! ❤️ 🙏 I've been playing with patterns for dependency injection and just found the factory/Env pattern

Just had the same issue when trying to use hono for the first time. I have "next": "^14.2.4", "hono": "^4.4.8","@hono/node-server": "^1.11.4", None of the the documentation examples worked. I tired some other syntaxes like:

//1.
import { Hono } from "hono";
import { handle } from "hono/vercel";

const app = new Hono().basePath("/api");

export const GET = handle(
  app.get("/hello", async (c) => {
    return c.json({
      message: "Hello!",
    });
  })
);

//2.
import { Hono } from "hono";
import { handle } from "hono/vercel";

const app = new Hono().basePath("/api");

app.get("/hello", async (c) => {
  return c.json({
    message: "Hello!",
  });
});

export const GET = handle(app.get());

//3.
import { Hono } from "hono";
import { handle } from "hono/vercel";

const app = new Hono().basePath("/api");

app.get("/hello", async (c) => {
  return c.json({
    message: "Hello!",
  });
});

const handler = handle(app);
export { handler as GET, /* handler as POST ... */ };

all of these worked, and when i went back to the docs example, it was also magically working now 🤷‍♂️

[undesicimo]

Can report that i am reproducing this too. Implementation is right from getting started

    "@hono/node-server": "^1.12.1",
    "hono": "^4.5.6",
    "next": "14.2.4",

https://hono.dev/docs/getting-started/vercel

import { Hono } from 'hono'
import { handle } from '@hono/node-server/vercel'
import type { PageConfig } from 'next'

export const config: PageConfig = {
  api: {
    bodyParser: false,
  },
}

const app = new Hono().basePath('/api')

app.get('/hello', (c) => {
  return c.json({
    message: 'Hello from Hono!',
  })
})

export default handle(app)

[prettyirrelevant]

i'm also getting this error using hono & bun.

$ bun ./dist/index.js
Failed to find Response internal state key
Server is running on port 8787

However, running the command bun dev, this log entry does not appear.

package.json

  "scripts": {
    "dev": "tsx watch src/index.ts",
    "build": "tsc",
    "start": "bun ./dist/index.js",

Im getting the same error

[cif]

I had moment to return to my hono project core and https://github.com/honojs/middleware/issues/627#issuecomment-2219356454 solved the issue for me.

tl;dr update your dev server script to:

bun run --bun vite vs vite

In my case, only in the docker container was broken, so I had to make an additional "dev:docker" script but working for me now 🎉

[jlarmstrongiv]

I am receiving this same error with Deno. Neither switching to react@canary react-dom@canary nor react-dom/server.browser worked for me. Even hono’s JSX renderer had the same error.

[Sutikshan]

I am experiencing this issue on Windows. same setup works fine on Mac. But on Windows I am getting this error - ( have hono, bun, remix vite cloudflare pages setup)

PS C:\Users\61449\MDCode\tess-fs\web> bun run --bun remix vite:dev
