How can I specify the region of a Google Cloud Function?

I\'m currently using Google Cloud Function to build up my restful API. However, I\'ve found that it\'s slow because the my Google-Cloud-Function server is on \"us-central\",

If you are using the Firebase SDK:

Taken from the documentation - https://firebase.google.com/docs/functions/manage-functions#modify

// before
const functions = require('firebase-functions');

exports.webhook = functions
    .https.onRequest((req, res) => {
            res.send("Hello");
    });

// after
const functions = require('firebase-functions');

exports.webhookAsia = functions
    .region('asia-northeast1')
    .https.onRequest((req, res) => {
            res.send("Hello");
    });
