Overview

Built to learn how to stitch a fully serverless stack together from scratch, from authentication through to automated deployment.

Architecture

The React front end is hosted on Azure Static Web Apps and signs people in with Google through Firebase. Every API call carries the Firebase ID token, which the Azure Functions verify with the Firebase Admin SDK before reading or writing MongoDB Atlas.
