如何使用Cloud Functions for Firebase检测浏览器类型？

Question

Inside a Cloud Function, I would like to serve different pages for mobile and desktop. I would like to know :

1. if its mobile or desktop (or a good guess) that want this page
2. If possible to get the browser/Google default language

The goal is to serve different users with different urls.

     exports.contentServer = functions.https.onRequest((request, response) => {

     //determine here if its mobile or not

You can use the following npm package:

https://www.npmjs.com/package/detect-browser

Install it by executing in the terminal:

npm i detect-browser

Then you can do for example:

const { detect } = require('detect-browser');
const browser = detect();

// handle the case where we don't detect the browser
if (browser) {
  console.log(browser.name);
  console.log(browser.version);
  console.log(browser.os);
}
