I am trying to test Firebase analytics in a test page. Below is the code.
However, I see no traffic on the analytics plots.
No errors in the page logs. How should I continue to test my firebase is setup right? I just used it out of the box.

firebase.database is not a function
(9 answers)
Closed 3 years ago.
I am working on an application for android that lets people login and add their data for an amusement park and I also need an app to view the data stored in the database (such as name, birthdate, children etc) on a PC. I have tried to write a web app but I have a problem connecting it to the database. I am new to databases so it might be from my code, can someone help me? The app only needs to show me the database all the time and update when a person registers.
Currently, I am getting this error:
Uncaught TypeError: firebase.database is not a function

Here is my index.html file:

Along with firebase-app and firebase-analytics, you must import the firebase-database service.

I'm working on a vuejs + firebase project and i was trying to import firestore but when i access my page, this is displayed into the console: ReferenceError: require is not defined
I'v tried to put the import section in mounted() but it says my that i need to put the import stuffs in the top, that's what i did
This is below my html (register.html) body:

The top of my register.js

require("firebase/firestore");
var app = new Vue({

},
And mounted()
if(this.numberOfInit = 0)
firebase.initializeApp({
apiKey: 'AIzaSyCNYH-sKZZXZhZt5LxQSDqwet7OTo5KgHM',
authDomain: 'thelogoagency.tk',
projectId: '1:101296201242:web:00d0e7e3554b518d'
});
this.db = firebase.firestore();
this.numberOfInit ++
this.db.collection("users").add({
first: "Ada",
last: "Lovelace",
born: 1815
})
.then(function(docRef) {
console.log("Document written with ID: ", docRef.id);
})
.catch(function(error) {
console.error("Error adding document: ", error);
});
}
It should normaly just work fine because it copied it from firebase's doc.
I know i'm probably doing it all wrong :) Thank for helping
If you're using Javascript and not NodeJS, you just must link your lib with
<script src="https://my/lib.js"></script>
So you can remove your require line :)
Require notation is only used when you are using npm and compiling the JS code. I think that you intend to only use the CDN script tag so you can remove the require line.
Install firebase-admin & firebase on npm , and then try this one "require('firebase-admin')" instead of require("firebase/firestore"); , and a note for you, it is impossible to run Backend Service in Client Side
The way i fixed it was, i just removed these two lines!
const firebase = require("firebase");
require("firebase/firestore");
not needed if you are using javascript, and not NodeJS.
you only need these cdns
<script src="https://www.gstatic.com/firebasejs/8.0.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.0.1/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.0.1/firebase-firestore.js"></script>
and to start to firestore:
firebase.initializeApp(firebaseConfig);
var db = firebase.firestore();
I am just beginning to use the Firebase Web Cloud Messaging and stumbled upon an issue where I can not proceed.
The cloud messaging is integrated with a Tizen Web application(Samsung device application), where the goal is to use cloud messaging and to receive messages.
The console shows´ Uncaught SyntaxError: Unexpected token ´ to a line in the .html file.
Here is where the code stops/malfunctions: return.messaging.getToken();
How do I need to solve this problem?
I tried using this Firebase link (this link it the first page of the documentation)
This part is included and written to .html

See:
https://firebase.google.com/support/release-notes/js#cloud-messaging

Deprecated requestPermission(). Use the native browser API Notification.requestPermission() instead.
In any case, try to use Notification.requestPermission().
I am trying to upload an image on firebase cloud storage with web javascript. I am getting "firebase.firestore () is not a function" on my console. Am I going any wrong way?
I have done insert and fetch data on firebase database. But I have to stop for upload image on firebase cloud storage.

var firebaseConfig = {

storageBucket: "XXX",
messagingSenderId: "XXX",

};
// Initialize Firebase
var defaultProject = firebase.initializeApp (firebaseConfig);
// Get a reference to the database service
var fileName = selectedFile.name;
var storageRef = firebase.firestore ().ref ('image' + fileName).put (selectedFile);
updating node on the computer seemed to have fixed the issue. I updated it to v16.15.1
change
firebase.firestore ().ref ('image' + fileName).put (selectedFile);
to
firebase.storage().ref('image' + fileName).put (selectedFile);
here is my Javascript code. its simply copy from the firebase Docs

after clicking my save button it shows the error mention below.
when i use the same code on simple project without any JS or Bootstrap it works fine but same code i placed in My real project with Bootstrap it shows errors

Fallback font will be used while loading:
By doing
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase.js"/></script>
<script src="https://www.gstatic.com/firebasejs/5.3.0/firebase-firestore.js"></script>
you load the 'firestore' Firebase service twice, see the doc: https://firebase.google.com/docs/web/setup
You should either do
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase.js"></script>
or
<!-- Firebase App is always required and must be first -->
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase-app.js"></script>
<!-- Add additional services that you want to use -->
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase-firestore.js"></script>
Also note that in your code you have mixed versions (i.e. 5.4.2 and 5.3.0). Most probably something to avoid.
Following your comment below, in order to check that it writes correctly to the db, modify you code as follows and just open the HTML page (the set() method will be triggered automatically)
