I am working on react application using vite and I am using latest version of react-router-dom v 6.23.0. My react application is build on the subdirectory (./new-mobile/dist) of main directory.
Here is my main.tsx file
Login
import ReactDOM from 'react-dom/client'
import App from './App'
import './index.css'
import store from '../redux/store.js'
import { Provider } from 'react-redux'
import {RouterProvider, createBrowserRouter} from 'react-router-dom';
import App3 from './App3'
import TestFile from './TestFile'
const basename = '/new-mobile/dist';
const router = createBrowserRouter([
{
path: '/',
element: <App />,
children: [
{
path: 'testfile',
element: <TestFile />
}
]
},
{
path: 'app3',
element: <App3 />
}
],
{
basename: basename
});
ReactDOM.createRoot(document.getElementById('root') as HTMLElement).render(
<Provider store={store}>
<RouterProvider router={router} />
</Provider>
);
And here is the vite.config.ts file
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import Checker from 'vite-plugin-checker';
// https://vitejs.dev/config/
export default defineConfig({
plugins: [
react(),
Checker({ typescript: true }),
],
base: './new-mobile/dist'
})
The main problem is when i am going on home page https://my-domain/new-mobile/dist it it working correctly, but when I go to its nested page (https://my-domain/new-mobile/dist/testfile) or child/sub-page like (https://my-domain/new-mobile/dist/app3) it breaks outs.
Also, this router is working fine on my local setup but breaks on test environment.
Things I tried: I tried adding basename but is is also not working. I tried jsx version of router, but still not working.
when I try to access /app3, this comes. broser image
I'm integrating Firebase App Check into my Android app and have configured it with the SHA-256 certificate fingerprint from my Google key. However, the setup isn't working, and all requests to Firebase are blocked.
Error output: Error getting App Check token; using placeholder token instead. Error: n8.j: Error returned from API. code: 403 body: App attestation failed.
I've followed the docs:
Enabled APIs
Add the code in my app
Firebase.initialize(context = this)
if (BuildConfig.DEBUG) {
Firebase.appCheck.installAppCheckProviderFactory(
DebugAppCheckProviderFactory.getInstance(),
)
} else {
Firebase.appCheck.installAppCheckProviderFactory(
PlayIntegrityAppCheckProviderFactory.getInstance(),
)
}
Added the SHA256 of the signature key provided in the Play console -> key management section
It works on debug but not on release.
Is there a specific setting that I might be missing, or could this be an issue with the fingerprint itself?
I am currently writing a chat app using react native. In my app, I am trying to fetch data from firebase and restructure it so that it can be displayed in the flatList of the chatscreen of my app. I have written the below code to achieve the aforementioned action:
const [groupChatMessageData, setGroupChatMessageData] = useState();
const [testMessages, setTestMessages] = useState();
const groupId = props.route.params && props.route.params.chatId;
const getNewGroupMessages = async (chatId) => {
try {
const app = getFirebaseApp();
const dbRef = ref(getDatabase(app));
const messagesRef = child(dbRef, `messages/${chatId}`);
const snapshot = await get(messagesRef);
return snapshot.val();
} catch (error) {
console.log(error);
}
};
useEffect(() => {
if (!groupId) return;
const getGroupMessages = async () => {
const data = await getNewGroupMessages(groupId);
setGroupChatMessageData(data);
};
getGroupMessages();
if (groupChatMessageData) {
const groupChatMessages = [];
for (const key in groupChatMessageData) {
const message = groupChatMessageData[key];
groupChatMessages.push({
key,
...message,
});
}
setTestMessages(groupChatMessages);
} else {
return;
}
}, []);
console.log("groupChatMessageData");
console.log(groupChatMessageData);
console.log("groupChatMessages");
console.log(groupChatMessages);
console.log("testMessages");
console.log(testMessages);
The data structure of "groupChatMessageData" is as follows:
{"-abcdefg": {"readBy": {" abcdefg ": [Object]}, "sentAt": "2024-04-26T07:16:19.414Z", "sentBy": "abc123", "text": "Hi"}, "-bcdefgh": {"readBy": {" bcdefgh ": [Object]}, "sentAt": "2024-04-27T05:17:36.020Z", "sentBy": " bcd234 ", "text": "Hi"}}
After running the code, I expect that there would be terminal logs showing for "groupChatMessageData", "groupChatMesages" and "testMesages". However, it appears that only the "groupChatMessageData"can be fetched from the firebase but the data restructuring of "groupChatMessageData" to "groupChatMesages" failed. Moreover, it appears weird that the "testMessages" can sometimes be shown on the terminal log (when I commented out the "groupChatMessages") but sometimes failed. Regardless of the aforemtnioned, the data stored in the "testMessages" can never be displayed in the flatList.
Grateful if anyone could help. Thanks in advance!

How can I fix this problem ?
I am facing some weird problem with setting a hosting site in a firebase project.
Here is the situation.
I want to use this name as a hosting site in my firebase project:
https://worldwonders.webapp.com/
But if I try to set it up, I get this message:
Site ID is unavailable. Available: worldwonders-9709b
At this point all is clear since I am already using the URL:
https://worldwonders.webapp.com/
inside another firebase project.
From now on things get less clear. I go to my other project and remove the site using worldwonders.webapp.com. It therefore becomes available for use.
The problem is that when I come back to my original project to set the hosting site the way I want, I still get the same kind of message as before, though the URL has been freed. What am I missing ? Or what do I need to do to keep using the URL below ? (that I was using up to now)
https://worldwonders.webapp.com/
i have already stored the image in the firebase storage with the path is "Avatar/Assists/0654234.jpg". and i use this code from chat gpt. But the problem i have is it's said "firebase.storage is not a function". IS there another way that i can get URL image from storage?
const express = require('express')
const bodyParser = require('body-parser')
const admin = require('firebase-admin')
const serviceAccount = require("./serviceAccountKey.json")

const firebase = require('firebase/app');
require('firebase/storage');
const firebaseConfig = {

i am trying to code a screenshot system the takes a screenshot then uploads it to firebase storage idk how to do it can someone make me one i can just edit i just cant figure it out ive been trying to find someone to help but i cant find anyone to help i need someone to just help make this reach out if you can help it would really be needed for my app i am making in unity and i would be very thankful.
ive been trying to find someone to help but i cant find anyone to help i need someone to just help make this reach out if you can help it would really be needed for my app i am making in unity and i would be very thankful.
I have an app that uses OpenAI and like many others my key was recently compromised.
I have this simple code:
const functions = require('firebase-functions');
const OpenAI = require("openai");
const openai = new OpenAI({
apiKey: functions.config().openai.key,
});
exports.generateText = functions.https.onCall(async (data, context) => {
try {
const response = await openai.chat.completions.create({
messages: [{ role: 'user', content: data.prompt }],
model: 'gpt-3.5-turbo',
});
return { response: response.choices[0].message.content };
} catch (error) {
throw new functions.https.HttpsError('internal', 'Failed to generate text from OpenAI.');
}
});
that I then call within my iOS app as follows:
let functions = Functions.functions()
func generateText(prompt: String, completion: @escaping (String?, Error?) -> Void) {
functions.httpsCallable("generateText").call(["prompt": prompt]) { result, error in
if let error = error as NSError? {
if error.domain == FunctionsErrorDomain {
let code = FunctionsErrorCode(rawValue: error.code)
let message = error.localizedDescription
let details = error.userInfo[FunctionsErrorDetailsKey]
print(code, message, details)
return
}
}
if let textResponse = (result?.data as? [String: Any])?["response"] as? String {
completion(textResponse, nil)
} else {
completion(nil, NSError(domain: "AppErrorDomain", code: -1, userInfo: [NSLocalizedDescriptionKey: "Failed to parse function response"]))
}
}
}
However as I'm not a backend engineer, I'm wondering if this is secure, or what is to stop someone using this endpoint? E.g. is this automatically restricted to being called from my app? Is there a way to do that?
I note other responses ask to authenticate the user via a login, but I would rather avoid that within my app.
Thank you!
I am creating a app that will read data from firebase and display it on a map. The app keeps crashing because there are hell lot of records to retrieve from the database. I need a way with which I get only the latest node data and not the entire data snapshot.
MainActivity.java:
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback{
FirebaseDatabase db;
DatabaseReference dbReference;
TextView speed_disp;
public List<LatLng> polygon;

return longitude;
}

private double latitude=19.10815888216128;
private double longitude=72.83706388922495;
public void setCord(String lat,String lon){
this.latitude=Double.parseDouble(lat);
this.longitude=Double.parseDouble(lon);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
polygon = new PolyList<>(10);
setContentView(R.layout.activity_main);
db = FirebaseDatabase.getInstance();
speed_disp=findViewById(R.id.speed);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);

// Add marker position to polygon list
polygon.add(current);
// Draw polyline
if (polygon.size() >= 2) {

I want to read only the newest node from the real-time database. Also, I would appreciate if you guys could improve my code.
I've deployed a Nuxt 3 application with Server-Side Rendering (SSR) on Firebase, utilizing Firebase Hosting and Cloud Functions. My app uses the Nuxt Image module with the default IPX provider for image optimization. While everything functions as expected in the local development environment, I encounter a persistent issue in production: all optimized images return a 404 Not Found error.
Example issue:
In production, attempting to access optimized images via URLs structured like /_ipx/f_webp&s_1460x722/images/hero.png results in a 404 error. These URLs are generated by the Nuxt Image module and work without issue locally.
Example use (default configuration):
<NuxtPicture src="/hero.png" preload sizes="sm:100vw lg:1460px" height="722" width="1460" alt="Hero billede" :img-attrs="{ class: 'w-full' }" />
Does anyone know how to fix this?
I have this code below which grabs data from my firebase database, works great! However I now wish to add another feature. when the have made a selection how do I then get the text to show in a text view. My text view Id is 'mTxt'. Please could someone kindly help, I have been trying for hours. I have watched many tutorials however still no luck. Thanks in advance.
My Spinner code:
spinnerV = findViewById(R.id.spinner);
spinnerRef = FirebaseDatabase.getInstance().getReference("Spinner");
spinnerList = new ArrayList<>();
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item, spinnerList);
spinnerV.setAdapter(adapter);
Showdata();
}
private void Showdata() {
spinnerRef.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot snapshot) {
for (DataSnapshot item : snapshot.getChildren()) {
spinnerList.add(item.getValue().toString());
}
adapter.notifyDataSetChanged();
}
@Override
public void onCancelled(@NonNull DatabaseError error) {
}
});
}
I have been trying to resolve this, with no joy..
I have a text box, when you enter a name into the text box, and press submit it will upload to firebase. Then a spinner in an app will show they names.
this is the code to upload which uploads the input data to the Realtime database.
function InsertData() {
push(ref(db, "Spinner/" ),{
Name: enterName.value
})
I have attached a picture. the code above when I submitted the name 'Matthew' you will see it sores it as a child under the random key. I need it to store inline exactly like the 'test one you can see at the top.I hope this makes sense.
I have a datagrid that displays some user data that I have existin in my Firebase DB. At the end of each row on the table, I have an action button that I am looking to display a modal when clicked.
I have the table and modal set up, but am wondering how I should pass the data from each row to the modal when it is clicked.
Here is the code for the datagrid:
const columns = [
{ field: 'firstName', headerName: 'First Name', width: 100 },
{ field: 'lastName', headerName: 'Last Name', width: 100 },
{ field: 'email', headerName: 'Email', width: 150 },
{ field: 'permission', headerName: 'Role', width: 100 },
{ field: 'street', headerName: 'Address', width: 150 },
{ field: 'city', headerName: 'City', width: 100 },
{ field: 'livingState', headerName: 'State', width: 100 },
{ field: 'zip', headerName: 'Zip', width: 100 },
{
field: "action",
headerName: "Action",
sortable: false,
renderCell: (params) => {
const onClick = (e) => {
// Enter logic to pass data to modal here
};
return <Button onClick={handleOpen}>
<ModeIcon />
</Button>;
}
},
];
Here is what the table looks like (Action button on the end of each row)

i almost tried everything without any success also i browser consoel i got the following error : Uncaught SyntaxError: Identifier 'observeDomChanges' has already been declared (at ruleApplier.js:1:1)
but there is no ruleApplier.js in the project at all and the docx for react and firebase have nothing about it :( anyone faced such issue ?!! any suggestion will be helpful at this point :D
I have a springboot project and added firebase dependency and all related things. When I run the project locally, everything works fine. I am using firebase admin sdk to send notifications. The code for sending is:
try {
messagingService.send(message);
logger.info("Firebase notification sent to user: "+user.getUsername());
saveLog(true, "Notification Sent", pushNotificationLog);
return true;
}catch (FirebaseMessagingException e) {
logger.info("Firebase did not send notification to user: "+user.getUsername()+ " Error Message: "+e.getMessage());
saveLog(false, e.getMessage(), pushNotificationLog);
return false;
}
As soon as I do the same on my remote server with different application properties, I get the exception while sending the notification, this is what it says: 2024-03-18 07:27:14.759 INFO 1 --- [nio-8091-exec-4] c.p.service.FirebaseNotificationService : Firebase did not send notification to user: zubair Error Message: Unknown error while making a remote service call: Error getting access token for service account: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext), iss: [email protected]
I have used cryptographic algos in some places of my code and they are working fine, only this isn't.
I tried running my local with the application properties of the remote server and it worked fine. I am unable to figure out the issue.
I'm going through the Firebase tutorial for create a "FriendlyChat" web app. I made it to Step 6.
At this point, it tells you to run the following command
firebase emulators:start
When I do this, however, I get an error.
firebase emulators:start i emulators: Starting emulators: auth, functions, firestore, hosting, storage i emulators: Shutting down emulators. i hub: Stopping emulator hub
Error: Assertion failed: resolving hosting target of a site with no site name or target name. This should have caused an error earlier
I've looked at my firebase.json file and see the following for hosting. Is there something wrong here?
"hosting": [
{
"source": ".",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"frameworksBackend": {
"region": "us-central1"
}
},
{
"target": "friendlychat",
"source": ".",
"frameworksBackend": {}
}
],
Per the tutorial instructions, running the command "firebase emulators:start" should have resulted in the following response. hosting: Local server: http://localhost:5000. Instead, I get the described error.
I want to build editable profile screen that user can upload their image file to profile.
When user upload image, CircleAvatar is changing but application don't save user statement. If I restart application or push another screen, It come back default image. What I confuse thing is firebase storage have image file that user uploaded.
profile_screen.dart
Uint8List? _image;
void selectImage() async {
Uint8List img = await imageSelector(ImageSource.gallery);
setState(() {
_image = img;
});
saveProfile();
}
void saveProfile() async {
String resp = await StoreData().saveData(file: _image!);
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: StreamBuilder<DocumentSnapshot>(
stream:
_firestore.collection('Users').doc(currentUser.email).snapshots(),
builder: (context, snapshot) {
if (snapshot.hasData) {
final userData = snapshot.data!.data() as Map<String, dynamic>;
return ListView(
children: [
const SizedBox(
height: 50.0,
),
Stack(
alignment: Alignment.center,
children: [
_image != null
? CircleAvatar(
radius: 80,
backgroundImage: MemoryImage(_image!),
)
: const CircleAvatar(
radius: 80,
backgroundImage: NetworkImage(

return downloadUrl;
}

String resp = "Some Error Occured";
try {
String imageURL = await uploadImageToStorage('ProfileImage', file);
_firestore.collection('userProfile').add({

image_selector.dart
import 'package:flutter/material.dart';

imageSelector(ImageSource source) async {
final ImagePicker imagePicker = ImagePicker();
XFile? file = await imagePicker.pickImage(source: source);
if (file != null) {
return await file.readAsBytes();
}
print('No Images Selected');
}
I think it is related user statement setting or something but I don't really know how to figure out.
Image file have successfully uploaded :
pubspec.yaml or ios/info.plist or firebase rule setting was done.
I was following this two video.
