Nativescript-plugin-firebase: Angular 5 onAuthStateChanged never called

[giorgiopiatti]

I was trying to see if there weren't any issues with this plugin and the last version of nativescript (3.4) and angular (5.0.0)...

When I try to subscribe to the event

onAuthStateChaged 

from the init method or by calling the listener, nothing is triggered. Nothing is passed to the callback function.

_Update_

I've investigated a bit more and I found out that the error happens when I initialize firebase, in fact the initialization is never completed but no error is caught by the promise.
When I also try to use other functions, it give me the message that I must run the initialization first.

All seems to work but when I try to subscribe to the event

onAuthStateChaged

from the init method or by calling the listener, nothing is triggered.
Nothing is passed to the callback function.

If anyone can share a simple project reproducing this issue then I'm glad to take a look. In the meanwhile, please compare your code to the Angular demo app in this repo which seems to work fine.

[giorgiopiatti]

@EddyVerbruggen I've used the demo app code, forking directly from this repository and updating to Angular 5.1.0 as showed there https://github.com/giorgiopiatti/nativescript-plugin-firebase/tree/master/demo-ng

Thanks ;)

Also having this issue

[EddyVerbruggen]

Are you implying with Angular 5.0.0 it was working fine?

[NicholasSmilovic]

I believe I was having a similar problem. After firebase.init I was able to login, but the onAuthStateChange Listener was not firing. Putting firebase.init inside a 1 second timeout made it operational. This happened on angular 5, and maybe 4 too.

[giorgiopiatti]

Thankyou @NicholasSmilovic Wrapping firebase.init inside a 1-second timeout resolved the issue.
setTimeout(()=>{ firebase.init(()=>{...}) },1000)

@EddyVerbruggen No also with Angular 5.0.0, wasn't working but with the suggestion of Nicholas also is solved.
