Firestore + Realtime Database: presence comes to offline after a minute and never turn back online...
This question already has an answer here:
Android - Firestore/Firebase Realtime Database “.info/connected” returns wrong connection state
1 answer
I build application with firestore, react-native and react-native-firestore. Now I use only firestore in my project. I want to implement presence for that app, and found solution: https://firebase.google.com/docs/firestore/solutions/presence?authuser=0
I started by writing simple code:
firebase.database().ref(".info/connected").on("value", snap => {
console.log(".info/connected", snap.val());
});
just to test how it works.
It outputs this
11-21 14:48:03.117 6502 6571 I ReactNativeJS: '.info/connected', false
11-21 14:48:03.710 6502 6571 I ReactNativeJS: '.info/connected', true
11-21 14:49:02.892 6502 6571 I ReactNativeJS: '.info/connected', false
As you can see, right after application startup, connected status becomes true within a second. But after ~1 minute, it becomes false and never goes back to true. Meanwhile application is fully operate, queries sent to firestore succesfully finished and etc.
I think it happens because I actually do not perform any query to Realtime Database. Am I right?

You are correct: if you don't listen for any other data, the Firebase SDK will auto-close its connection to the Realtime Database after a minute. To prevent this, add a separate listener to the root of the empty database, for example by callingfirebase.database().ref().keepSynced(true). This is a known issue in the documentation. See stackoverflow.com/questions/53320480/…

You should implement the Logic for realTime Database, an then you need use CloudFunctions to keep Realtime Database and Cloud Firestore in sync. it is the only way. have you ever used cloud functions in the past?

No, I build slightly different case, and I do not need the whole power of presence. I want to indicate end user that connection is lost (and remove indicator when connection restores).

Not only internet connection - connection to firebase servers. Becuase internet connection is generally available, but firebase servers may be not reachable.
