In Episode 1, we hosted an Express API on Azure App Service, and in Episode 2, we deployed a React frontend to Azure Static Web Apps. Now, we will connect our full-stack application to a managed, production-ready relational database: Azure Database for PostgreSQL Flexible Server.
In this guide, we will provision a PostgreSQL instance, configure its firewall rules, secure connection credentials using environment variables, and query the database directly from our Express backend.
Prerequisites
Before getting started, make sure you have:
The Express project from Episode 1 running locally and on Azure.
