Firebase v3.8.0 and Ionic 3 Slow Connection on Initialization

[Jason Ho]

Hi, the issue was reported at here https://github.com/driftyco/ionic/issues/11290 and here https://forum.ionicframework.com/t/ionic-3-super-slow-with-firebase-on-device-emulator/87233/45

 I am facing the same issue. We are not sure if this is due to Ionic 3 or Firebase 3.8.0 which is causing the delay.

The first Firebase connection is slow but subsequent listeners are normal.

This is only happened to real devices but not browser. The same code is working normal with browser.

Here is the android (real device) console log from firebase.database.enableLogging(true);

2017-04-21 21:04:50.211 main.js:122484 Ionic Native: deviceready event fired after 3091 ms

2017-04-21 21:05:52.728 main.js:40326 p:0: Listen on /firebaseURL-not-shown for default  

As you can see from the log, it took 48s for the "Auth token" to be fired.

If I downgraded the firebase version to 3.7.6, the delay was significantly reduced.

Thanks Jason for reporting this. We will look into it.

Ok, so it seems the reason is we now support OAuth signInWithRedirect in Cordova:

https://firebase.google.com/docs/auth/web/cordova

In order to do so, we require some plugins to be installed.

If you install the plugins, you should be good. 

We are quickly working on a fix to not require the plugins if you do not plan on calling signInWithRedirect. Should be out in the next release.

Thanks for reporting this issue once again and we apologize for the inconvenience.

Hi Bassam,

Thank you for clarification. 

I had installed all the plugin and the firebase connection is lighting fast.

Hey Jason, this should be fixed in 3.9.0 release:

https://firebase.google.com/support/release-notes/js#3.9.0

Let me know if you discover any issues.
