How to deploy express to Firebase?

Currently i'm learning express and Firebase. I can deploy an angular or react page (front-end) to Firebase.

And now, i'm trying to create the back-end using express, then i realize, i cant just simply deploying it as another project to Firebase since Firebase hosting will looking for index.html as entry point (*please correct me if i'm wrong). I've tried Firebase functions but still can't.

Can i set a javascript (expressjs) file to Firebase as entry point?

thanks.

You can deploy an Express app to Cloud Functions for Firebase as an HTTP trigger. There is a sample that illustrates this. The basic form of implementation looks like this in your Cloud Functions index.js:

const functions = require('firebase-functions')
const express = require('express')
const app = express()
// configure app here, add routes, whatever
exports.api = functions.https.onRequest(app)

Now you can access your routes under the path https://your-assigned-hostname/api/whatever

EDIT

You also need to configure your firebase.json file if you want to redirect every request to the Express app.

Add this line inside the hosting object: "rewrites" : [{"source" : "**", "function" : "api"}]
