I have a Firebase app written in Polymer and I can't use Auth.
It tells me 'Error: The specified authentication provider is not enabled for this Firebase.' but I have allowed this in the console.
I tried switched the Firebase URL to the one used in the demo and it worked like a charm but when I tried using my URL it doesn't.
Am I using a wrong URL?
My Firebase element is below
<firebase-auth
id="firebaseLogin"
user="{{user}}"
status-known="{{statusKnown}}"
location="https://teste-firebase-822c4.firebaseio.com"
provider="{{provider}}"
on-error="errorHandler"
on-user-created="userSuccessHandler"
on-password-changed="userSuccessHandler"
on-password-reset="userSuccessHandler"
on-user-removed="userSuccessHandler"></firebase-auth>
Is this wrong? https://teste-firebase-822c4.firebaseio.com
Thanks for your time.
The current version of the Polymer firebase-auth component (1.0.12), is built for the Firebase version from firebase.com:
Element wrapper for the Firebase authentication API (https://www.firebase.com/docs/web/guide/user-auth.html).
That means it uses the 2.x version of the Firebase JavaScript SDK.
If you created your Firebase project on the new Firebase Console, it will only work with the 3.x version of the JavaScript SDK. You'll need an updated version of the component, which doesn't seem to be available yet.
I suspect the plan is to deprecate firebase-element and firebase-auth and migrate to the new Polymerfire element.
Here the relevant Github issue discussion.

I installed firebase with react native expo using expo add firebase, then
I created a file (firebase.tsx) and added the Firebase configuration and initialized the app like in this screenshot with correct values].
I have added the google-services.json and
GoogleService-info.plist to the root of my expo project like the documentation say and i am importing firebase in my api service like this import Firebase from './../../../firebase'.
In my register function I call the firebase create user function
const response = await Firebase.auth().createUserWithEmailAndPassword(values.email.value, values.password.value)
The response is never returned, and if I use . then nothing happens either.
If I log firebase.auth I get an object with my API key and app name, etc. so Firebase is installed, but whenever I call the database for sign in or to access a collection nothing happens.
This is my package.json.
This is my app.json.
I added bundleIdentifier and googleServicesFile to iOS and package and googleServicesFile for Android.
currently Firebase seems not to be working in expo if you are using the android configuration. I have tried the web configuration and it has worked for me. Here is the youtube tutorial for it. Watch from 38:20 to set up.
My app engine is using Firebase Admin Node.js SDK to use Firebase.firestore (and other products). I want to use firebase.firestore.FieldValue.increment to implement a counter.
But it doesn't seem Firebase Admin Node.js SDK has firebase.firestore.FieldValue.increment.
Should I use Firebase Javascript Client SDK for it? If so, I have to use both Firebase Javascript Client SDK and Firebase Admin Node.js SDK. Is it OK?
I am using Node.js 8 and "firebase-admin": "^7.0.0".
admin.firestore.FieldValue is just an alias to this type defined in the #google-cloud/firestore package: https://cloud.google.com/nodejs/docs/reference/firestore/1.3.x/FieldValue
So anything available in that type is readily available in admin.firestore.FieldValue as well. That includes increment(). The documentation is just out of date.
Just loaded firebase 3.0 with react-native and getting the error
[fatal][tid:com.facebook.react.RCTExceptionsManagerQueue] Unhandled
JS Exception: Can't find variable: document
Is react-native supported yet?
React-native code:
var firebase = require('firebase')
// Initialize Firebase
var config = {
apiKey: '<apiKey>',
authDomain: '<app>.firebaseapp.com',
databaseURL: 'https://<app>.firebaseio.com',
storageBucket: 'firebase-<app>.appspot.com'
};
firebase.config(config)
The newest version of firebase uses the document variables that are used in web applications and the RCTWebSocket or RCTView doesn't work the same way. (I'm not 100% sure about all the details). Anyway, you can just install an older version of firebase and it will work for you. Assuming you have npm installed follow these instructions.
Uninstall Firebase from your react-native project npm uninstall firebase --save
Install version 2.4.2 of firebase npm install firebase#2.4.2 --save
Happy Firebaseing!
Firebase JS SDK 3.1 just got released and is now compatible with React Native!
See release notes.
I was able to get Firebase 3.0.2 to load in React Native by putting the following in a .js file and importing it at the top of index.ios.js:
global.location = {
href: ''
};
global.screen = {
};
global.document = {
getElementsByTagName: function(){}
};
global.parent = global;
There may be other gotchas - I have not explored further than this but it might get Firebase 3 working for you.
Firebase 3.x is not supported in RN (yet..).
Issue
I think the issue relates to the auth module's dependency on the browser's window variable.
Will it be officially supported?
According to the following discussion thread from the Firebase team, they are presently working on 3.x support. There is however no release time frame set.
Google Groups Discussion.
Workarounds
Option 1 (with FB 2.x)
From Jacob Wenger:
If React Native support is a blocker for you, please continue to use
the 2.x.x SDKs until we resolve this issue. The 2.x.x SDKs will
continue to work, even after you migrate to the new console..`
Option 2 (with FB 3.x)
From Jacob Wenger:
As a "workaround" if you don't need auth (unlikely, I know, but still
worth mentioning), you should be able to do the following:
var app = require('firebase/app');
var database = require('firebase/database');
To use last version of Firebase with ReactNative you can use Firebase Bridge.
I have a demo app here.
Whilst the Firebase JS SDK does work on react native now, it is mainly built for the web and is generally not the best solution for react-native.
The Firebase Web SDK runs entirely on react native's JS thread, therefore affecting your application frame rate (the link explains this well).
In my tests, the native firebase SDK's has been roughly 2-3 times quicker than using the web SDK.
But on top of the potential performance impacts there's a lot of features you'll be unable to use with the web SDK on android/ios devices. For example:
Notifications / FCM
Offline capabilities
Storage upload/download
Firebase Crash Reporting
Analytics
Use of social authentication providers
The best approach would be to run with the native android/ios firebase sdk's and have a bridge between them and your js code (i.e. a native module setup).
Thankfully you don't have to implement this yourself, there's already modules out there to do this for you:
react-native-firebase for example mirrors the the web sdk's api js side but executes on the native side using the native android & ios firebase sdk's. It's fully compatible with any existing firebase js logic that you may have already implemented and is intended as a drop in replacement for the web sdk.

When using Firebase on ReactNative, it will show such error message:
can't find variable process
However, if I require firebase/lib/firebase-web.js manually, it will show:
can't find variable document
How can I resolve this?
I just went through the same issue while trying to use sockets.io in my react native app so hopefully I can help.
The reason that you cannot use firebase's node module is because there hasn't been a polyfill created yet for websockets support (which firebase is dependent on) in react native.
If you take a look at issue #619 in react native's repo you'll find the current discussion on creating a websockets api polyfill.
The way that we solved it is by using Jason's modified version of the sockets library and creating our own repo around just that file. Then we added the line below to our package.json dependencies.
"react-sockets": "crewapp/react-native-sockets-io"
The reason that Jason's version of the sockets.io client file works is because react-native is added as a user agent. You can find the code that makes this change at the top of the file:
window.navigator = {
userAgent: "react-native"
}
Once you've gone through these steps you should be able to require sockets.io / firebase as normal.
Just figuring it our. Pavan's answer is helpful, but it is not quite true when using with Firebase.
For firebase, please follow the steps:
Download the firebase-debug.js from wsExample. Or you can just install wsExample by npm and require the firebase-debug.js inside it.
Use badfortrains's forked React-Native:
"react-native": "git://github.com/badfortrains/react-native#WebSocket"
New the Firebase like this:
var firebase = require("../../firebase-debug.js");
var rootRef = new Firebase(Const.FB_ROOT);
Things should just work now!
I had issues with socket.io on React Native too, solution was to get notifications about new data and if data is big enough - get it by simple RESTfull request. in my case data was small enough to be sent all within notifications API.
I was using GCM service to send notification to phone from nodejs server. BTW, it uses less battery then socket connection and works great :)
