Issue: Type Error
I setup a Firestore Cloud Function to call from my Android app which is being called as expected, however I am unable to access a Firestore document from within the method and receiving a TypeError in the logs.

Firestore doesn't have a ref() method. Realtime Database does. You're probably confusing the two.
With Firestore, you deal with collections and documents, and there are different methods to get a hold of collection and document references. Maybe you meant to use the doc() method instead, like this?
admin.firestore().doc('qa/content/feeds/main/content/'+contentTitle)
Sorry wrong answer.
You need to pass credential when initializing app.
const admin = require('firebase-admin');
const functions = require('firebase-functions');
admin.initializeApp(functions.config().firebase);
var db = admin.firestore();
or
admin.initializeApp({
credential: admin.credential.cert({
projectId: '<PROJECT_ID>',
clientEmail: 'foo#<PROJECT_ID>.iam.gserviceaccount.com',
privateKey: '-----BEGIN PRIVATE KEY-----\n<KEY>\n-----END PRIVATE KEY-----\n'
}),
databaseURL: 'https://<DATABASE_NAME>.firebaseio.com'
});
initialize the sdk

I have a custom endpoint setup for my FireStore database.
For now, all I want is to print all values to console, but when I call it from a client, the request times out and the console only says:
#firebase/database: FIREBASE WARNING: The Firebase database
'project-name' has been disabled by a database owner.
(https://project-name-de56eb8.firebaseio.com)
Here's my code. Can anyone tell me what is (what thins are) wrong with it?
const util = require('util');
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const language = require('#google-cloud/language');
const client = new language.LanguageServiceClient();
const express = require('express');
const app = express();
app.post('/calculateAverage', async (request, response) => {
const bodyUserId = request.body.id
let query = admin.database().ref(`/user_info/`);
try {
const snapshot = await query.once('value');
snapshot.forEach((childSnapshot) => {
console.log("key: " + childSnapshot.key + " value: " + childSnapshot.val())
});
response.send({"snapshot await": "ok"});
} catch(error) {
console.log('Error getting messages', error.message);
response.send({"snapshot await error": error.message});
}
});
exports.api = functions.https.onRequest(app);
The problem is that you no use firebase realtime data.
in the options of firebase you have database and next *Cloud Firestore and
*Realtime Database, select Realtime Database and after, active this option and with this the solution
I'm trying to build an Android application. In my Firestore database I have Users collection and Counters collection. In Counters collection I have userCounter. What I want to do is whenerever a new user logs in and I push it to firestore, userCounter to increase.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.addNewUser =
functions.firestore.document('Users/{userID}').onCreate((event) => {
var db = admin.firestore();
var counterRef = db.collection("Counters");
var temp = counterRef.doc("0").data().userCounter++;
counterRef.doc("0").update(
{
userCounter: temp
});
});
In this state, this function doesn't work, and I'm a newbie so I'd appreciate any help.
Thx beforehand
EDIT
After implementing Firebaser and Pablo Almécija Rodríguez's answers, my code looks like this.
const Firestore = require('#google-cloud/firestore');
const firestore = new Firestore({
projectId: process.env.GCP_PROJECT,
});
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();
exports.addNewUser =
functions.firestore.document('Users/{userId}').onCreate((snapShot) => {
const userCounterRef = db.collection('Counters').doc('Users');
return db.runTransaction(transaction => {
const doc = transaction.get(userCounterRef);
console.log("1");
const count = doc.data();
console.log(`5`);
const updatedCount = count + 1;
console.log(`6`);
return transaction.update(userCounterRef, {counter: updatedCount })
})
});
And this is the firebase console log. The problem is
const count = doc.data();
TypeError: doc.data is not a function
Firebase Console Log
I suggest you to create a collection named counters and inside it a document named users to handle counter for users. Here is the structure:
- counters (collection)
- users (document)
count: 0 (field)
Then, you should use a transaction to perform an update on this counter document to make sure you are working with up-to-date data to deal with concurrency (multiple accounts created at the same time)
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();
exports.addNewUser =
functions.firestore.document('users/{userId}').onCreate((snapShot) => {
const userCounterRef = db.doc('counters/users');
return db.runTransaction(async transaction => {
const doc = await transaction.get(userCounterRef)
const { count } = doc.data()
const updatedCount = count + 1
return transaction.update(userCounterRef, {count: updatedCount })
})
});
https://firebase.google.com/docs/firestore/manage-data/transactions
EDIT: If you don't want to deal with async/await syntax, update your transaction like that :
return db.runTransaction(transaction => {
return transaction.get(userCounterRef)
.then(doc => {
const count = doc.data().count
const updatedCount = count + 1
transaction.update(userCounterRef, {count: updatedCount })
})
})
I have reproduced it in Cloud Functions, and this simple solution worked. Edited answer to fit Firebase, and it also uses the Firestore dependency for nodejs.
const Firestore = require('#google-cloud/firestore');
const firestore = new Firestore({
projectId: process.env.GCP_PROJECT,
});
const functions = require('firebase-functions');
//I am not using next two lines right now though
const admin = require('firebase-admin');
admin.initializeApp();
exports.helloFirestore =
functions.firestore.document('users/{userID}').onCreate((event) => {
const doc = firestore.doc('Counters/UserCounter/');
doc.get().then(docSnap => {
//Get the specific field you want to modify
return docSnap.get('userCount');
}).then(field => {
field++;
//Log entry to see the change happened
console.log(`Retrieved field value after +1: ${field}`);
//Update field of doc with the new value
doc.update({
userCount: field,
});
});
});
The wildcard you used should be fine, just be careful with the full path for the collection, mind the upper/lower case. For this case, this is how my package.json looks like:
{
"name": "sample-firestore",
"version": "0.0.1",
"dependencies": {
"#google-cloud/firestore": "^1.1.0",
"firebase-functions": "2.2.0",
"firebase-admin": "7.0.0"
}
}
I am working on a dialogflow agent and using fulfillment to fetch data from the firestore.
I have a firestore collection called Users which has name and location fields. But am getting the error which causes the fetching of data to fail.
Warning, estimating Firebase Config based on GCLOUD_PROJECT.
Initializing firebase-admin may fail
The fulfillment code for the agent is as follows
'use strict';
const functions = require('firebase-functions');
const { WebhookClient } = require('dialogflow-fulfillment');
const { Card, Suggestion } = require('dialogflow-fulfillment');
const admin = require('firebase-admin');
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
var name='';
var location='';
admin.initializeApp(functions.config().firebase);
const db = admin.firestore();
function getUserDetails(agent)
{
name= agent.parameters.name;
location=agent.parameters.location;
console.log("buyer name is " + name);
db.collection("Users").doc("101").set({
name: name,
location:location});
agent.add(`User has been inserted`);
}
intentMap.set('Buy Car', getUserDetails);
agent.handleRequest(intentMap);
})
This form of initialization for the Firebase Admin SDK is deprecated:
admin.initializeApp(functions.config().firebase);
You should initialize like this instead:
admin.initializeApp();
I have a React Native application, running on a firebase backend. I have integrated with Stripe. The token is created by the client, and the firebase cloud function creates the charge with that token. I have built the app and tested payments using the test keys in Stripe.
I have now replaced the test keys with the live keys.
The live public key is working in the React Native application, and is creating a token successfully.
here is the function for creating the token code in the React Native application
import Stripe from 'react-native-stripe-api';
async payByCard() {
const { user } = this.props;
const uid = user.uid;
const { number, exp_month, exp_year, cvc } = this.state;
this.setState({ loading: true });
const apiKey = 'pk_live_#######################';
const client = new Stripe(apiKey);
try {
const token = await client.createToken({
number,
exp_month,
exp_year,
cvc,
});
this.props.addToken({ token }, uid);
} catch (error) {
this.setState({ error: error.message, loading: false });
}
}
The firebase cloud functions, however, is still using the secret test key.
here is the loud function for creating a charge.
import * as functions from 'firebase-functions';
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const stripe = require('stripe')(functions.config().stripe.testkey)
export const stripeCharge = functions.database
.ref('/payments/{userUid}/{paymentUid}')
.onWrite((change, context) => {
const payment = change.after.val();
const userUid = context.params.userUid;
const paymentUid = context.params.paymentUid;
if (!payment || payment.charge || !payment.pendingBasket) return;
return admin.database()
.ref(`/users/${userUid}`)
.once('value')
.then(snapshot => {
return snapshot.val();
})
.then(customer => {
const amount = Number(payment.pendingBasket.total * 100).toFixed(0)
const idempotency_key = paymentUid;
const source = payment.token.id;
const currency = 'gbp';
const description = `Athalens ${customer.address.FirstName} ${customer.address.LastName} - ${customer.address.PostCode}`
const charge = {amount, currency, description, source};
return stripe.charges.create(charge, { idempotency_key });
}).catch((error) => {
console.log('error 1 =' + error.message);
admin.database()
.ref(`/payments/${userUid}/${paymentUid}/status`)
.set(error.message)
})
.then(charge => {
admin.database()
.ref(`/payments/${userUid}/${paymentUid}/charge`)
.set(charge)
if (charge.status === "succeeded") {
customerOrders(userUid, paymentUid)
photographerUid(userUid, paymentUid)
clearBasket(userUid)
confirmation(userUid, paymentUid);
} else {
decline(userUid, paymentUid)
}
}).catch((error) => {
console.log('error 2 =' + error.message);
})
})
The process I am doing to upload the Secret key to firebase:
1. Williams-MBP:~ williamgoodhew$ cd /Users/williamgoodhew/projects/athalens/athalens_server_code/basket/functions
2. Williams-MBP:functions williamgoodhew$ firebase functions:config:set stripe.token=“sk_live_#################”
3. Williams-MBP:functions williamgoodhew$ firebase deploy --only functions
When I test the live payment system, a token is created, but no charge is created. and I receive the following error in the cloud functions log:
No such token: tok_############; a similar object exists in live mode, but a test mode key was used to make this request.
I have got in contact with Firebase and it was a silly error my end.
In my cloud function, I had initialized my test key "
const stripe = require('stripe')(functions.config().stripe.testkey)
" instead of using "stripe.token".
I changed stripe.testkey to stripe.token.and everything worked out fine.
I am trying to make a notification function to deploy using cloud functions of firebase
I did the first part of the code and it was successfully done which is:
'use-strict'
const functions = require('firebase-functions');
//const paypal=require('paypal-rest-sdk');
const admin=require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotification=functions.firestore
.document("Users/{user_id}/Notifications/{notification_id}")
onWrite((change, context)=>{
const user_id=context.params.user_id;
const notification_id=context.params.notification_id;
});
without returning promise and it was ok but when i tried to complete like this:
'use-strict'
const functions = require('firebase-functions');
//const paypal=require('paypal-rest-sdk');
const admin=require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotification=functions.firestore
.document("Users/{user_id}/Notifications/{notification_id}")
.onWrite((change, context)=>{
const user_id=context.params.user_id;
const notification_id=context.params.notification_id;
return admin.firestore().collection("Users").doc(user_id)
.collection("Notifications")
.doc(notification_id)
.get()
.then(queryResult=>{
const from_user_id=queryResult.data().from;
const from_data=admin.firestore()
.collection("Users").doc(from_user_id).get();
const to_data=admin.firestore().collection("Users")
.doc(user_id).get();
return Promise.all([from_data,to_data]).then(result=>{
const from_name=result[0].data().name;
const to_name=result[1].data().name;
console.log("from :"+from_name+"TO"+to_name);
});
});
// console.log("user_id"+ user_id+ "notification_id"+notification_id);
});
I have these 2 errors in node.cm:
1-Avoid nesting promises
2-each then()should return a value
how can i fix this problem???
Send push notification through FCM and cloud function when a change in Firestore database
You can try like this
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.sendNotification = functions.firestore
.document('/users/{documentId}')
.onWrite((change, context) => {
console.log("CHANGE in DOCUMENT ID : " + context.params.documentId);
// Fetch data using standard accessors
const userId = change.after.data().userId;
const ownerId = change.after.data().ownerId;
console.log('We have a new request UID:', userId, 'for owner:', ownerId);
const owner_data = admin.firestore().collection('users').doc(ownerId).get();
const user_data = admin.firestore().collection('users').doc(userId).get();
return Promise.all([owner_data, user_data]).then(result => {
const ownerFCMToken = result[0].data().fcmToken;
const userName = result[1].data().displayName;
console.log("OWNER Token : " + ownerFCMToken + " USER: " + userName);
const payload = {
notification: {
title: 'Test title!',
body: `${userName} sent you a following request.`
// icon: follower.photoURL
}
};
admin.messaging().sendToDevice(followedFCMToken, payload)
.then(function (response) {
console.log("Push response : " + response);
return response
})
.catch(function (error) {
console.error("Error in sending push");
});
});
