index.js

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

exports.helloWorld = functions.https.onRequest((request, response) => {
 response.send(
    `<!doctype html>
    <html>
    <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" type="text/css" href="style.css">
    </head>
    <body>
    Hello ...
    </body>
    </html>
    `);
});

When it comes to Cloud Functions HTTP triggers, they are not designed to serve static content like HTML, CSS, and JS files automatically. Instead, these triggers are meant for executing code in response to HTTP requests such as API calls.

If you wish to deliver static content alongside your HTTP requests, consider utilizing Firebase Hosting in conjunction with Cloud Functions. Firebase Hosting will handle serving your static content, while when properly set up, it can also direct specific URLs to Cloud Functions for processing by your custom code.

An alternative approach would be configuring an express app within Cloud Functions and defining routes within it. This way, incoming requests that are directed straight to Cloud Functions can access content deployed alongside your functions. However, leveraging Firebase Hosting is typically the more common and beneficial solution.
