Next.js + PostgreSQL + Containerized App

Overview

Build and maintain production-grade Next.js applications backed by PostgreSQL, shipped as Docker images (and optionally via Docker Compose).

Priorities:

• Correctness for money/decimal math (no floats)
• Safe DB access (pooling, migrations, transactions)
• Reproducible container builds (multi-stage, minimal runtime image)

Version targets (verified 2026-01-16)

• Next.js: 16.1.x (latest stable observed: 16.1.2)
• PostgreSQL: 18.x (current minor observed: 18.1)

Guidance:

• Prefer staying on the latest minor for your chosen Postgres major.
• Treat Next.js security advisories as “upgrade now” events.
