Calling Netlify function from Nuxt3 server/api - what URL to use?

Support

Hello, I’ve created my first netlify function inside my Nuxt3 project:

netflify/functions/hello.mts

import type { Context } from "@netlify/functions"

export default async (req: Request, context: Context) => {
  return new Response("Hello, world!")
}

I want to call this funcion from inside Nuxt3 server/api/call-function.ts but I am not sure about which path to use?

Do I need to use https://nuxt3-netlify-functions.netlify.app/.netlify/functions/hello in my $fetch request, or something like BASE_URL to not hardcode it or how can I use something like /.netlify/functions/hello?

export default defineEventHandler(async (event) => {
  
  // QUESTION - how to call this without the full URL?
  // ❌ this does NOT work locally
  // const whatever = await $fetch('/.netlify/functions/hello')

  // when running `netfliy dev` this will work if I use this full URL
  // http://localhost:8888/.netlify/functions/hello

  // how is this supposed to work in production? Do I something like BASE_URL?
  
  // this works
  const whatever = await $fetch('https://nuxt3-netlify-functions.netlify.app/.netlify/functions/hello')
  console.log("🐥🐥", whatever)
  return whatever
})

My function is up and running here:
https://nuxt3-netlify-functions.netlify.app/.netlify/functions/hello

My whole repo is here:

Many thanks in advance!

Yes, that’s the ideal way. But if you absolutely want to make it dynamic, you can use:

  1. process.env.URL
  2. OR you can use getRequestURL(event).origin

Though you can avoid all this and simply add whatever functionality you wish to do in Netlify Functions inside the Nuxt API call.

Thanks man! That clears things up for me!
