Rewrite this Firebase Web SDK Version 8 syntax into Version 9

Question

I have a problem with Firebase in my React Native app. I've found a quick fix online, but it's written in Firebase Web version 8 syntax:

firebase.firestore().settings({ experimentalForceLongPolling: true, merge: true });

How can I rewrite it in Version 9 syntax?

Answer 1

You need to pass your settings to the initializeFirestore(app, settings) method.

As you will read on this doc page :

initializeFirestore(app, settings) initializes a new instance of Firestore with the provided settings. Can only be called before any other function, including getFirestore() . If the custom settings are empty, this function is equivalent to calling getFirestore() .
