How do I deploy my firebase functions into a specific region?

Question

const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp()

exports.sendChatMsgNotification = functions.region('europe-west1')
firestore
  .document('chats/{idChat}/messages/{idMessage}')
  .onCreate((snap, context) => {
    console.log('----------------start function--------------------')

I am trying to deploy my Firebase cloud function into europe-west1 region because the default is us-central1, but I am always getting errors.

Yes, I have already tried to follow the official documentation https://firebase.google.com/docs/functions/locations#android. I just have no idea how to apply it correctly. I have tried many times.

If someone can just show me how to apply the correct way using my code above, would be highly appreciated!

Are you missing a dot (.) after the region and before firestore? — Jason Berryman

Oh it was really just the dot (.) after all! How have I not noticed this all the time. Thanks for pointing it out! — Sufian

Before

exports.sendChatMsgNotification = functions.region('europe-west1')
firestore

After (working)

exports.sendChatMsgNotification = functions.region('europe-west1').
firestore

I was only missing a dot (.) before "firestore". Thanks @Jason Berryman for pointing it out!

For v2: https://firebase.google.com/docs/functions/2nd-gen-upgrade#set_runtime_options

import {onDocumentCreated} from "firebase-functions/v2/firestore";
import {setGlobalOptions} from "firebase-functions/v2";
// locate all functions closest to users
setGlobalOptions({region: "us-west2"});
export const userCreated =
  onDocumentCreated("users/{userId}", (event) => { ... });

For firebase v2 gen cloud functions you can use the below style.

exports.yourapi = onRequest({ region: "us-central1" }, expressjscode);
