Connection State return number value, not boolean

[dzuncoi]

Hi,

Currently, I'm using .info/connected to detect app connection state, as

firebase.database().ref('.info/connected').on('value', snapshot => {
    const connectionState = snapshot.val()
})

And I expect connectionState should return boolean value (true of false), as this Firebase doc.

But it doesn't, my connectionState value always return false at the first time, then return 1 if app has connection and 0 if not. Is it a correct behavior?

Ps: I'm still fine with those value, just want to confirm this behavior.

Seems like incorrect behaviour, can you tell me which platform this issue is on, android or ios?

@Salakar
I'm using iOS 10.3, react-native-firebase: 1.0.0-alpha12

@dzuncoi Speaking with @Salakar, on Android Firebase SDK it returns as true/false, however on iOS Firebase SDK it returns 1/0. The problem is it's part of a Reference, so there'd have to be some custom logic to change this (needs double checking).

Thanks for investigating this issue. I'm porting my app to Android as well, so I'll check and inform if there is anything should be changed.

Might also be an issue with the type conversion in RNFirebase also, @dzuncoi could you try see what setting/reading a boolean value on any ref returns?

We have tests for this that check all types including Booleans and it's passing, may be some weird edge case in your instance where it isn't.

The iOS SDK docs say it's bool, or at least a boleanValue:

I've tested on Android with the same codes and it return boolean values. And on Android,

my connectionState value always return false at the first time

this behavior does not happen as iOS.
It's a little bit weird. I'll test on real device soon.

This has been the case for a while but I just deal with it by testing for either 1 or true.
Maybe it's not so elegant but it works haha

Use == instead of ===

Closing this as there's not much I can do about it, native SDK's return the value like this, but android returns an actual boolean value.
