Am trying to access Firebase Cloud Storage in my Cloud functions but i keep getting the following error in the cloud functions log:
Error: Failed to import the Cloud Storage client library for Node.js. Make sure to install the "#google-cloud/storage" npm package. Original error: SyntaxError: Unexpected token {

admin.initializeApp();
const db = admin.firestore();
exports.initializeNewVideoUpload = functions.firestore.document('new-videos-uploads/{id}').onCreate(async (snapshot, context) => {
const data = snapshot.data();
const fileNames = data.file_names;
const bucket = admin.storage().bucket('trumateappdev.appspot.com');
fileNames.forEach(async fileName => {
const actualFile = bucket.file(fileName);
const resumableUpload = await actualFile.createResumableUpload();
const uploadEndpointUrl = resumableUpload[0];
data.resumable_urls.push(uploadEndpointUrl);
});
await admin.firestore().collection('new-videos-uploads').doc(context.params.id).update(data);
});
Below are the dependencies in my package.json:
"#google-cloud/storage": "^5.5.0",
"firebase-admin": "^9.2.0",
"firebase-functions": "^3.11.0"
PS: Am on the Spark Plan
I found this solution here. Add this to your package.json:
"engines": {"node": "8"}
Apparently this problem occurs because your node.js version is too old

I am trying to deploy some cloud functions using algolia search but it gives me some errors.
When deleting this line:
const algoliasearch = require('algoliasearch') and functions that related to algolia, it deploys successfully.
The error is:

Remove these installations and reinstall again solves the problem .
npm install -g firebase-tools
firebase login
firebase init
cd functions
npm install algoliasearch --save
firebase functions:config:set algolia.appid="YOUR_APP_ID" algolia.apikey="YOUR_API_KEY"
I successfully wrote some tests for my Firebase functions, however now I want to test functions that manipulate Firestore data.
to do so I execute the following
export GOOGLE_APPLICATION_CREDENTIALS="my-project-key.json"
export FIRESTORE_EMULATOR_HOST="localhost:8080"
firebase emulators:start --import ./functions/test/fixture --project my-project
and then I run
npm run test
The test code is as follows:
const test = require("firebase-functions-test")()
const functions = require("../index")
describe("Tests", () => {
it("Do test", async () => {
const wrapped = test.wrap(functions.doTest)
const result = await wrapped({id:"1"})
})
})
The index file imported contains:
const functions = require("firebase-functions")
const admin = require("firebase-admin")
admin.initializeApp()
exports.doTest = functions.https.onCall(async (data) => {
const {id} = data
const vehicleRef = admin.firestore().collection("vehicles").doc(id)
const vehicle = await vehicleRef.get()
})
Yet every time I call a Firebase function that accesses Firestore I get the following error (in this case on vehicleRef.get()):
Error: Could not load the default credentials. Browse to https://cloud.google.com/docs/authentication/getting-started for more information.

What am I doing wrong?
Looks like you're doing everything right, except I don't think you're initializing the initializeApp object correctly. Try this in your index:
admin.initializeApp({
projectId: 'my-project',
credential: admin.credential.applicationDefault(),
});
You'll have to add a condition to use this version based on whether or not the environment variable is set though.
I'm creating a react application. I have code like this
async componentDidMount() {
const questions = await axios.get('getQuestions');
console.log(questions);
}
(I have a baseURL set up for axios and all, so the URL is correct)
I created a firebase function as follows (typescript)
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp();
admin.firestore().settings({ timestampsInSnapshots: true });
const db = admin.firestore();
exports.getQuestions = functions.https.onRequest(async (request, response) => {
const questions = [];
const querySnapshot = await db.collection('questions').get();
const documents = querySnapshot.docs;
documents.forEach(doc => {
questions.push(doc.data());
});
response.json({ questions: questions });
});
Now when I build and run firebase deploy --only functions, and then visit the url directly, everything works. I see my questions.
But in the react app, I get the following error
Access to XMLHttpRequest at '.../getQuestions' from origin
'http://localhost:3000' has been blocked by CORS policy: No
'Access-Control-Allow-Origin' header is present on the requested
resource.
After some googling, I tried
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp();
admin.firestore().settings({ timestampsInSnapshots: true });
const db = admin.firestore();
const cors = require('cors')({ origin: true });
exports.getQuestions = functions.https.onRequest(
cors(async (request, response) => {
const questions = [];
const querySnapshot = await db.collection('questions').get();
const documents = querySnapshot.docs;
documents.forEach(doc => {
questions.push(doc.data());
});
response.json({ questions: questions });
})
);
But that just gave me an error when I ran firebase deploy --only functions
✔ functions: Finished running predeploy script. i functions:
ensuring necessary APIs are enabled... ✔ functions: all necessary
APIs are enabled i functions: preparing functions directory for
uploading...
Error: Error occurred while parsing your function triggers.

And tbh, even if this command worked, I don't know if it is the correct solution
Got it :) I was doing something silly
import * as cors from 'cors';
const corsHandler = cors({ origin: true });
exports.getQuestions = functions.https.onRequest(async (request, response) => {
corsHandler(request, response, async () => {
const questions = [];
const querySnapshot = await db.collection('questions').get();
const documents = querySnapshot.docs;
documents.forEach(doc => {
questions.push(doc.data());
});
response.status(200).json({ questions: questions });
});
});
This answer will help someone who facing cors error.
01 - Create Firebase Function Called BtnTrigger (You can name whatever you like)
// Include Firebase Function
const functions = require('firebase-functions');
// Include Firebase Admin SDK
const admin = require('firebase-admin');
admin.initializeApp();
//cors setup include it before you do this
//run npm install cors if its not in package.json file
const cors = require('cors');
//set origin true
const corsHandler = cors({ origin: true });
//firebase function
export const BtnTrigger = functions.https.onRequest((request, response) => {
corsHandler(request, response, async () => {
//response.send("test");
response.status(200).json({ data: request.body });
});
});
Then Run firebase deploy --only functions this will create your firebase function. if you need you can check it from your Firebase Console.
02 - Create Function Trigger from your Application from your application code
i used same BtnTrigger name to understand it properly you can change variable here but httpsCallable params should same as your Firebase Function Name you created.
var BtnTrigger =firebase.functions().httpsCallable('BtnTrigger');
BtnTrigger({ key: value }).then(function(result) {
// Read result of the Cloud Function.
console.log(result.data)
// this will log what you have sent from Application BtnTrigger
// { key: value}
});
Don't Forget to import 'firebase/functions' from your Application Code
To make sure this is as clean and isolated as possible, I created a new test project with nothing in it other than these steps.
I then enabled cloud firestore in the console. I created a new collection called "blarg" (great name, eh!). I added a document to it, and used the auto-id, then added a field named "humpty" with the string dumpty. It looks like this in the console:
I created a directory called signatures in the storage section of the firebase console. I want to write a file into this directory when my function (below) triggers.
I then added a cloud function with the following code. It shows up (I assume) correctly in the functions section, with the name testItOut and triggering on the event document.update for /blarg/{eventId}.:
const functions = require('firebase-functions');
const os = require('os');
const fs = require('fs');
const path = require('path');
require('firebase-admin').initializeApp();
exports.testItOut = functions.firestore
.document('blarg/{docId}')
.onUpdate((change, context) => {
console.log( "Inside #testItOut" );
const projectId = 'testing-60477';
const Storage = require('#google-cloud/storage');
const storage = new Storage({
projectId,
});
let bucketName = 'signatures';
let fileName = 'temp.txt';
const tempFilePath = path.join(os.tmpdir(), fileName);
console.log( `Writing out to ${tempFilePath}` );
fs.writeFileSync(tempFilePath, "something!" );
return storage
.bucket( bucketName )
.upload( tempFilePath )
.then( () => fs.unlinkSync(tempFilePath) )
.catch(err => console.error('ERROR inside upload: ', err) );
});
The package.json looks like this:
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"lint": "eslint .",
"serve": "firebase serve --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"dependencies": {
"#google-cloud/storage": "^1.7.0",
"firebase-admin": "~5.12.1",
"firebase-functions": "^1.0.3"
},
"devDependencies": {
"eslint": "^4.12.0",
"eslint-plugin-promise": "^3.6.0"
},
"private": true
}
If I change the value of the key "humpty" I see the function invocation. But, I get the error inside the logs.
ERROR inside upload: { ApiError: testing-60477#appspot.gserviceaccount.com does not have storage.objects.create access to signatures/temp.txt.

at Object.handleResp (/user_code/node_modules/#google-cloud/storage/node_modules/#google-cloud/common/src/util.js:131:18)
...
This is as simple as it can get, I'd assume. What am I doing wrong? I thought calling initializeApp() gave my function rights to write to the storage bucket for the account automatically?
The only strange error I see is that billing is not setup. I thought this was necessary only if you use external APIs. Is Google Storage an "external API?" The log message does not indicate that's the issue.
The issue was that I mistakenly thought the call to bucket was to set the subdirectory inside the bucket. Instead of bucket('signatures') I should have made it an empty call like bucket() and then provided an options parameter (like { destination: '/signatures/temp.txt' }) for the upload call:
const functions = require('firebase-functions');
const os = require('os');
const fs = require('fs');
const path = require('path');
const admin = require('firebase-admin');
admin.initializeApp();
exports.testItOut = functions.firestore
.document('blarg/{docId}')
.onUpdate((change, context) => {
console.log( "Inside #testItOut" );
const storage = admin.storage()
let fileName = 'temp.txt';
let destination = '/signatures/temp.txt';
const tempFilePath = path.join(os.tmpdir(), fileName);
console.log( `Writing out to ${tempFilePath}` );
fs.writeFileSync(tempFilePath, "something!" );
return storage
.bucket()
.upload( tempFilePath, { destination } )
.then( () => fs.unlinkSync(tempFilePath) )
.catch(err => console.error('ERROR inside upload: ', err) );
});
I got confused because I saw lots of examples in firebase docs where there are calls to bucket("albums") (like this: https://cloud.google.com/nodejs/docs/reference/storage/1.6.x/Bucket#getFiles) and assumed this meant the bucket can be used to set a subdirectory for uploads. It's obvious to me now the difference, but I was thrown off because the calls to bucket did not look like bucketname-12345.appspot.com as I see in the firebase storage console.
Don't bother trying to use the Google Cloud Storage SDK like this:
const Storage = require('#google-cloud/storage');
const storage = new Storage({
projectId,
});
Instead, just use the Admin SDK after you initialize it. The Admin SDK wraps the Google Cloud Storage SDK. When you initialize admin, you are also implicitly initializing all of the components it wraps.
const admin = require('firebase-admin')
admin.initializeApp()
const storage = admin.storage()
// Now use storage just like you would use #google-cloud/storage
The default service account that's used when you init admin with no args like this should have write access to your project's default storage bucket.
I am trying to run isomorphic react app, using Firebase functions-samples.
But can't get the firebase database and I get the error "firebase.database is not a function"
const firebase = require('firebase')
// Load the Firebase database module.
require('firebase/database')
// Initialize Firebase using a client-side config.
const firebaseConfig = require('./client/firebase-config.json')
firebase.initializeApp(firebaseConfig)
const getDb = (ref) => firebase.database().ref(ref)
// Error firebase.database is not a function
Modules versions:
"firebase": "^4.13.0",
"firebase-admin": "~5.12.0",
"firebase-functions": "^1.0.2",
It works well with firebase-admin
const firebase = require('firebase-admin')
const firebaseConfig = require('./client/firebase-config.json')
firebase.initializeApp(firebaseConfig)
const getDb = (ref) => firebase.database().ref(ref)
