Overview (Angular)

This sample demonstrates the basic features of the Firestore class.

The Firestore class allows you to load and edit data stored in Firestore collections, exposing each collection as a CollectionView.

You can load, edit, filter, sort, group, and paginate the views as usual.

Editing requires authentication and is not demonstrated in this sample.

This example uses Angular.
