I am trying to convert my firebase implementation which previously used realtime database to use firestore as I like the idea of collections and the perks of using it.

How do I implement below into firestore equivalent?

firebase.database().ref('documentPath').push()

To have the same bahaviour in Cloud Firestore as you have in Firebase Realtime database when using the push() function, is to let Cloud Firestore auto-generate an ID for you. You can do this by calling add() function like this:

var addYourDoc = db.collection('documentPath').add({
  property_key: 'property_value',
}).then(ref => {
  console.log('document ID: ', ref.id);
});

The output in the console will be the actual generated id.
