Basically I am trying to have a firebase function simply output values in a document, I have only achieved this locally... but the function won't deploy to the cloud. Below is the function
const functions = require('firebase-functions');
const firebase = require('firebase/app');
require('firebase/firestore');
const firebaseConfig = {
projectId: "covid-info-bw"
};
const db = firebase
.initializeApp(firebaseConfig)
.firestore()
// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
exports.helloWorld = functions.https.onRequest((request, response) => {
response.send("Hello from Firebase! Dawg I am beast");
});
exports.getData = functions.https.onRequest((req, res) => {
const docRef = db.collection('FunctionTest').doc('Cm38kBYShNnyuLVpizcy');
const getDoc = docRef.get()
.then(doc => {
if (!doc.exists) {
console.log('No such document!');
return res.send('Not Found')
}
console.log(doc.data());
return res.send(doc.data());
})
.catch(err => {
console.log('Error getting document', err);
});
This is a snippet from the package.json
"dependencies": {
"#firebase/app": "^0.6.1",
"#firebase/firestore": "^1.14.0",
"#google-cloud/firestore": "^3.7.4",
"firebase-admin": "^8.10.0",
"firebase-functions": "^3.6.0"
},
This is the error I am getting from running " firebase deploy --only functions:getData,functions:helloWorld"
λ firebase deploy --only functions:getData,functions:helloWorld

Functions deploy had errors with the following functions:
getData
helloWorld
To try redeploying those functions, run:
firebase deploy --only functions:getData,functions:helloWorld
To continue deploying other features (such as database), run:
firebase deploy --except functions
Error: Functions did not deploy properly.
You're not supposed to use the Firebase client SDKs for backend code. What you're trying to do can be achieved using only the Google Cloud Firestore SDK (#google-cloud/firestore) or the Firebase Admin SDK (firebase-admin, which just writes the Cloud SDK). Just remove the Firebase client SDKs (beginning with #firebase) and use only the backend SDKs you prefer.

I want to use p-queue npm nodejs. But it get me error. Help me why it was and how to fix it? Here my code:
const shell = require("shelljs");
const async = require("async");
const fs = require("fs");
const path = require("path");
const { default: PQueue } = require("p-queue");
const queue = new PQueue({ concurrency: 1 });
And this error:

FIXED, the names of the folders in my pc changed when uploaded to github
So, my app looks something like this
├── config

└── index.js
app.js
Here i have all my env variables, so I have a central point from which to extract them
require('dotenv').config()
module.exports = {
appPort: process.env.PORT,
appUrl: process.env.APP_URL,
appKey: process.env.APP_KEY,
frontendUrl: process.env.FRONTEND_URL
}
index.js
central file of the server
const express = require('express')
const cors = require('cors')
const app = express()
const { appPort, frontendUrl } = require('./config/app')
app.listen(appPort , () => {
console.log(`Server listening on port ${appPort}`);
})
The problem here is that when i deploy it and starts the server, it throws me error
node:internal/modules/cjs/loader:936
throw err;
^

and i really don't know why, because it works perfectly fine in my pc
the code for the whole project is actually much bigger, but only this files are the ones throwing me errors
Hope someone can help see what is happening that throws that error

first try to remove the globally installed express
then initialize a package.json file with npm init. Here you will have a list of your dependencies, scripts and name of your package and some other data.
Then install express with npm i express.
after installing try to run it with node server.js or npm start if you have written the script to run the start command in package.json
I got the answer

When deploying my cloud functions using the command firebase deploy I am getting this error for all of my functions:
! functions[deleteGame-DeleteGameFunction(us-central1)]: Deployment error.
Function load error: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?

'use strict';

const glob = require("glob");
const camelCase = require("camelcase");
const files = glob.sync('./**/*.f.js', { cwd: __dirname, ignore:
'./node_modules/**'});
for(let f=0,fl=files.length; f<fl; f++){
const file = files[f];

This index.js file is a way to organize your firebase cloud functions that I found on https://postmarkapp.com/blog/sending-transactional-emails-via-firebase-and-cloud-functions that got it from https://codeburst.io/organizing-your-firebase-cloud-functions-67dc17b3b0da
Thank you for your help!
It sounds like you need to run this from your functions directory:
npm install glob
And probably also
npm install camelcase
You can't require a module without first installing it into your project like this.
I am trying to use the onAuthStateChanged trigger but I am getting "is not a function" when using "firebase deploy".
when executing :
firebase deploy
I got the following error:
Error: Error occurred while parsing your function triggers.

I have also tried firebase.default.auth.onAuthStateChanged as mentionned in the solution posted by Joao Lopes in this question ut it gave the same error!
I have already my domain added Firebase project>Authentication>Sign-In Method>Authorized Domains.
I am using:Ubuntu 16.04,npm 5.6.0,Firebase Spark.
Here is my package.json:
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"serve": "firebase serve --only functions",
"shell": "firebase experimental:functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"dependencies": {
"consolidate": "^0.15.0",
"express": "^4.16.2",
"firebase-admin": "^5.8.2",
"firebase-functions": "^0.8.1",
"handlebars": "^4.0.11"
},
"private": true
}
and my index.js:
const functions = require('firebase-functions');
const firebase=require('firebase-admin');
const express=require('express');
const engines=require('consolidate');
firebase.initializeApp(functions.config().firebase);
const app=express();
app.engine('hbs',engines.handlebars);
app.set('views','./views');
app.set('view engine','hbs');
app.get('/',(req,res)=>{
res.render('index',{Loginsignup:"LoginSignup"});
});
/*Here is the probleme*/
firebase.auth().onAuthStateChanged(function(user) {
user.sendEmailVerification();
if(!auth.currentUser.emailVerified){
user.sendEmailVerification();
console.log('signed in');
}
});
/********************/
exports.app = functions.https.onRequest(app);
So what am I missing?
There is no onAuthStateChanged function in the firebase-admin SDK. This function is available only in the client-side package.
Firebase Admin Auth Reference: https://firebase.google.com/docs/reference/admin/node/admin.auth.Auth
Firebase Javascript Auth Reference: https://firebase.google.com/docs/reference/js/firebase.auth.Auth
You're trying to login with the admin SDK.
onAuthStateChanged dosen't reside here. https://firebase.google.com/docs/reference/admin/node/admin.auth
Start by adding the firebase client package to your project.
$ npm install firebase --save
and change const firebase=require('firebase-admin'); => const firebase=require('firebase');
That might be sufficient. Not sure if you need to pass diffrent credentials to initializeApp() once it's on the client side.
Here's the authoriziation in the client documentation.
https://firebase.google.com/docs/reference/node/firebase.auth.Auth
