Fullstack Serverless CI/CD in AWS Amplify Hosting with Postgres Database Branching

This guide explains how to integrate AWS Amplify Hosting CI/CD with Neon Postgres to test an application's environment or feature branches using real data enabled by Neon's database branching. The architecture automates the workflow and ensures each new feature or environment branch in your Amplify application has a corresponding, isolated database. This is especially useful for Server Side Rendering (SSR) applications built with frameworks like Next.js, Nuxt, Astro, and SvelteKit. Both Neon and Amplify Hosting are serverless, which means the underlying infrastructure doesn't require maintenance and scales down to zero when not in use. The integration involves a custom Bash script (neon-ci.sh) to manage Neon database branches alongside Amplify app branches.
