I am getting this error when i try to use the rtdb on an angularfire2 app.

I imported firebase as follows:
import * as firebase from 'firebase/app';
The following gives me the above error:
db = firebase.database();
Import it like this:
import * as firebase from 'firebase';
import 'firebase/firestore';
use AngularFire2, It can be insalled by npm

You should import like this:
import { initializeApp } from "firebase/app";
const firebaseConfig = {...};
const app = initializeApp(firebaseConfig);
You may want to visit this documentation and learn how to use Firebase Services such as Firestore.
In my React Native project I'm migrating react-native-firebase from version 5 to version 6 using this guide. In the Specific Module Installation section it says to import the functions module using #react-native-firebase/functions and then to import them with import functions from '#react-native-firebase/functions';. However, when I try to update this code:
import * as functions from 'firebase-functions';
import { FeedModel } from '../../../models/feed.model';
export const onFeedCreate = functions.firestore
.document('promos/{uid}')
.onCreate( async (
snapshot,
context
) => {
const promo = snapshot.data() as FeedModel;
console.log(promo);
});
by replacing the first line with #react-native-firebase/functions';, then the term firestore on the third line is underlined in red and says Property 'firestore' does not exist on type 'FirebaseModuleWithStaticsAndApp<Module, Statics>'.
How should I change my imports in order to run this function?
I am getting this error when running npm run dev
registerFunctions(firebase$1, fetch.bind(self));
^
ReferenceError: fetch is not defined
I figured rxfire doesn't import fetch, so I add this line to src/server.ts
global['fetch'] = require('node-fetch');
And the error is still there, any suggestions? I would think I would not have to add this at all.
I am just using rxfire in a src/firebase.ts file like so:
import firebase from "firebase/app";
import "firebase/auth";
import "firebase/firestore";
import "firebase/functions";
import * as config from "./config.json";
firebase.initializeApp(config);
export const auth = firebase.auth();
export const googleProvider = new firebase.auth.GoogleAuthProvider();
export const db = firebase.firestore();
export const functions = firebase.functions();
Thanks,

This was a specific error caused when trying to import "firebase/functions" on the server end in my firebase.ts file.
I was able to solve it by adding import 'isomorphic-unfetch' to server.ts. However, then I got this error:
registerFunctions(firebase$1, fetch.bind(self));
^
ReferenceError: self is not defined
I realized there apparently is no object to bind to on the backend, so I found a work around. I needed to not import it on the backend, which was a bigger Sapper Firebase problem.
See my post here for complete fix.
I had similar issue with this error stacktrace :

I solve it by updating the firebase import to
import * as admin from 'firebase-admin';
import firebase from 'firebase/app';
first install whatwg-fetch.
npm i --save whatwg-fetch yarn add --save whatwg-fetch pnpm i --save whatwg-fetch
create a file ./define-self.js
with this content
var global =
(typeof globalThis !== "undefined" && globalThis) ||
(typeof self !== "undefined" && self) ||
(typeof global !== "undefined" && global);
if (!global?.self) {
global.self = global;
}
on your index.svelte / _layout.svelte
<script context="module">
import "./define-self";
import "whatwg-fetch";
</script>
I used Google Analytics a lot for many sites...
I'm just releasing a first app with Firebase (Firestore + Firebase SDK with reactjs).
Then, I activated GA from my Firebase dashboard... but I cannot see any activity !
I probably need not to add plugin like "autotrack" ?
import 'autotrack';
ga('create', 'UA-XXXXX-Y', 'auto');
It's not clear because, it's impossible to find out the track ID (UA-XXXXX-Y) from my dashboard !
Do I really need it ? Where can I find it ?
I did't correctly initialized Analytics...
With firebase it's not a track ID but a measurementId
import app from 'firebase/app';
import 'firebase/analytics';
app.initializeApp({
//other config
measurementId : process.env.REACT_APP_MEASUREMENT_ID,
appId : process.env.REACT_APP_DEV_ID
})
//put inside your constructor
app.analytics()
This will solve the following error:
Error: firebase__WEBPACK_IMPORTED_MODULE_8___default.a.analytics is
not a function react
Documentation : https://firebase.google.com/docs/analytics/get-started?platform=web
The previous answer should be corrected like this:
import app from 'firebase/app';
import 'firebase/analytics';
app.initializeApp({
//other config
measurementId : process.env.REACT_APP_MEASUREMENT_ID,
appId : process.env.REACT_APP_DEV_ID
})
//put inside your constructor
app.analytics()
This will solve the following error:
Error: firebase__WEBPACK_IMPORTED_MODULE_8___default.a.analytics is
not a function react
My issue was the same as listed above:
Error: firebase__WEBPACK_IMPORTED_MODULE_8___default.a.analytics is not a function react
But the resolution was that I forgot to import the analytics module: import 'firebase/analytics';
If you are using Typescript:
// On index.tsx
import { initializeApp } from 'firebase/app';
import { initializeAnalytics } from 'firebase/analytics';
const firebaseConfig = {
... your config object ...
};
const app = initializeApp(firebaseConfig);
initializeAnalytics(app);
Firebase gone through a lot of new updates. Change imports like this;
import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';
import 'firebase/compat/analytics';
Got error while initializing Firebase configuration in expo react native. Unexpected token ";"
Enviroment:
Expo development
React native
firebase
visual studio code editor
What I want:
I am new , learning how to authenticate /login in react native application using firebase email/password method.
What I did:
In the code editor tool--> app.js--> I imported the firebase , created a const to define the firebase config parameters.
After that, I tried to initialize firebase .
What is the issue:
When I ran the app on my phone , the following error occurred.
SyntaxError: C:\Users\Jituni\bholmentorworld\App.js: Unexpected token, expected ";" (32:23)

import * as firebase from 'firebase';

appId:"b308d4b9d990db06",
};
firebase.initializeApp{firebaseConfig};
export default class App extends React.Component{
render() {
return <AppContainer/>;
}
};][1]
Expected result:
Should not receive error to initialize firebase
Actual result:
Error in initialing firebase
I recommend using a linter to catch any possible error, I personally use eslint with vs code.
firebase.initializeApp{firebaseConfig}; should be firebase.initializeApp(firebaseConfig);
