Can't use initFirebase() on 1.1.3 [Firebase isn't initialised] [Solutions proposed]

[BrainOverflown]

I just updated cordova-plugin-firebase to 1.1.3 and tried to use the initFirebase() method to get rid of the 'Firebase isn't initialised' error (note that the error got a typo in console log).

I'm getting the following error :
Uncaught (in promise): TypeError: _this.firebase.initFirebase is not a function TypeError: _this.firebase.initFirebase is not a function

my code : (note that this code [without initFirebase()] is totally working on another computer.
import {Firebase} from "@ionic-native/firebase"; public start() { return this.platform.ready().then(() => { this.firebase.initFirebase(); this.firebase.getToken().then(token => { console.log(token) this.api.post('tg.php', {token}).subscribe(() => { }); } ).catch(err => console.log(err)); }); }

***** EDIT ***** :

For those encountering the same problem, here is a walkthrough which seems to help most people :

• downgrading cordova-plugin-firebase to 0.1.18 which can be done like this :
  cordova plugin rm cordova-plugin-firebase
cordova plugin add cordova-plugin-firebase@0.1.18
npm install --save @ionic-native/firebase

if it doesn't work

• uninstalling and reinstalling the plugin with cordova plugin add cordova-plugin-firebase@1.0.5 then npm install @ionic-native/firebase --save

if it doesn't work

• try upgrading to 1.1.3 for @DomCostantino's trick :

declare var FirebasePlugin : any;

and then insert the cordova script include in your index.html file

<script type="text/javascript" src="cordova.js"></script>

and using the plugin like this:

FirebasePlugin.initFirebase();

For those needing a practical example of how to insert it in your own code, here is a snippet courtesy of @tgensol :

observableFromEvent(document, 'deviceready').pipe(first()).subscribe(() => {
FirebasePlugin.initFirebase();
FirebasePlugin.initAnalytics();
})

Depending on how you coded your application, this may have to go in your home.ts /or/ typescript associated with the page calling it /or/ in the provider calling for the getToken() functio.

If the problem isn't solved with this step by step, write down the encountered problems here so we can help troubleshoot for you and others.

[important note : for people having a hard time downgrading, try deleting manually plugins and platforms folders (after backuping them/!), then after plugin installation go for a : cordova platform add android]

Good luck

Ok when i downgrade to 1.0.5 it seems to work well, but as soon as i get to latest versions it doesn't work. Firebase JS needs to be compatible with plugin version. How can this be properly solved ?

Same issue here.

Using:

• Cordova 8.0.0
• Cordova Android 7.1.0
• Firebase Plugin 1.1.3

Thanks

initFirebase problem should be fixed declaring just below import section:
declare var FirebasePlugin;
and then insert the cordova script include in your index.html file
<script type="text/javascript" src="cordova.js"></script>
and using the plugin like this:
FirebasePlugin.initFirebase();

@DomCostantino Doesn't work for me :
"Unexpected token. A constructor, method, accessor, or property was expected."

I had this same issue. Got rid of the 'Firebase isn't initialised' error by downgrading to 1.0.5:

cordova plugin remove cordova-plugin-firebase
cordova plugin add cordova-plugin-firebase@1.0.5

Same problem. I created a stackoverflow question with a 50 reputation bounty

https://stackoverflow.com/questions/52140850/firebase-isnt-initialised-on-ios-ionic/52186436

@SimonKomlos this might be because iOS is still on firebase SDK 4.13.0 (see #796). I believe android is on the latest firebase version.

[BrainOverflown]

@soumak77 i don't think so, i have the same problem on Android with latest updates. as i told Firebase JS needs to be compatible with plugin version.

[soumak77]

@BrainOverflown I was specifically talking about the stackoverflow question @SimonKomlos posted. Though if v1.0.5 works, then I'm wrong since it's also on v4.13.0 for iOS.

[BrainOverflown]

@soumak77 got it ! Solution to this problem will make a lot of happy people.

People should try downgrading to 0.1.18 as advised on the Stackoverflow thread :

cordova plugin remove cordova-plugin-firebase cordova plugin add cordova-plugin-firebase@0.1.18 --save

[SimonKomlos]

@BrainOverflown did downgrading fix the problem for you?
