Custom server not working

[msukmanowsky]

Bug report

Describe the bug

Following the docs for custom server and routing, a simple server.js example runs locally but does not work when deploying to zeit.co.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Clone https://github.com/msukmanowsky/zeit-test and install dependencies npm install
2. Run npm run dev and navigate to http://localhost:3000/a (should show JSON response)
3. Deploy to Zeit via npm run deploy
4. Access https://yoursite.now.sh/a and you'll see you get a 404 error, not the correct JSON response

Expected behavior

Custom route /a should return JSON when deployed to zeit.co but it shows a 404 error.

System information

• OS: macOS
• Version of Next.js: 9.1.3

You could try using Next's API routes instead to serve a JSON response from a specified url.

Otherwise, Zeit Now has some configuration options for Routes: https://zeit.co/docs/configuration/#routes

{
  "routes": [{ "src": "/a" }]
}

Thanks @jamesmosier. API routes won't work for my use case (which by the way is a Shopify app).

Shopify adds some custom OAuth routes and a GraphQL proxy endpoint.

Tried adding that config but still have the same issue. Navigating to https://zeit-test.mikesukmanowsky.now.sh/a produces a 404 error.

I did some more thinking and you can combine the API routes and Now routing.

1. Create your API route under pages/api/a.js
2. Update your now.json to point to this API route:

   {
   "version": 2,
   "routes": [
       { "src": "/a", "dest": "/api/a" }
   ]
   }

@jamesmosier that does work, but the issue I have is that I need to use some Koa middleware and you can't really use those with the pages/api based approach.

Ahhh I see. Then from the resources I found, a custom server and Now won't work together:

All the recommendations I saw were when needing 1 off API endpoints with Next & Now, either use the API routes and now.json routing or create pages that handle this in getInitialProps, both of which won't work if you need a more complex server setup with Koa.

Custom servers do not work on ZEIT Now. You'll need to use our built-in router and potentially the upcoming Custom Routes RFC: #9081.

We'll be removing most of the custom server examples soon-ish. They shouldn't be needed for most applications!
