Experimental Long Polling in Firebase Web v9

I am attempting to set experimentalForceLongPolling = true for Firestore settings.

The reason for this is because without this, Firestore does not work with emulators in Cypress testing.

How does one set the settings, specifically this experimentalForceLongPolling setting, in the Firebase Web v9 SDK?

>Solution :

You need to use initializeFirestore instead of getFirestore to update any settings as shown below:

import { initializeFirestore } from 'firebase/firestore'

const db = initializeFirestore(app, { experimentalForceLongPolling: true })
