Server Component where to put?

in Nextjs v14 Server Components can be defined only inside /app? nowhere else I can define it?

I've defined an Arrow Function which uses headers() and returns the IP Address from X-Forwarded-For, and then I imported it in /app/page.tsx but I got an error.

any help where I can place such Arrow Function Codes? I am not defining "use server" explicitly or anything.

Thats a server action first of all not a server component, second of all, you need to provide some code and the actual error here.

// Nextjs
import { headers } from "next/headers"

export const getIPAddr = (): string => {
  const FALLBACK_IP_ADDRESS = "0.0.0.0"
  const forwardedFor = headers().get("x-forwarded-for")

  if (forwardedFor) {
    console.log("forwardedFor.split(", ")[0]", forwardedFor.split(",")[0])

    return forwardedFor.split(",")[0] ?? FALLBACK_IP_ADDRESS
  }

  console.log('headers().get("x-real-ip")', headers().get("x-real-ip"))

  return headers().get("x-real-ip") ?? FALLBACK_IP_ADDRESS
}
this is my code which I have defined inside /src/helpers/get-ip-addr/index.ts and then importing it in app/page.tsx and having a console to check the output

The error?
Egyptian MauOP
and I've /helpers/index.ts

which have the export again like below:

export * from './get-ip-addr'


so my import in /app/page.tsx becomes like

import { getIPAddr } from '@/helpers'
and this is the error

The error explains the problem.
Egyptian MauOP
but if I am importing it like import { getIPAddr } from '@/helpers/get-ip-addr' then there is no error
I am not clear on that
Clown
You cant be using headers from next/header inside the pages dir
U need to use app dir
Clown
This is so weird
@Clown Just do this
Egyptian MauOP
okay!..

I am trying to understand the other way, why it is not working
Clown
I'm not sure but what you are trying to do is a barrel import.

Exporting many files from a single file. Probably causing an issue and is VERY weird way of writing this kind of code.
