title: Do I need a backend for a firebase web app?
body: <p>I am curious with all the features of firebase, cloud functions, and client-side authentication, Firestore, etc. options, does it make sense to even use a 'backend' with a firebase web app? The reason I am asking is that I started a project with a react app and a node.js backend rest API service. I started to realize that with all of firebases features, it might make sense to scratch my backend entirely. What are everyone's thoughts? Thanks</p>
