# Skill: Docker + PostgreSQL + Node.js + ORM Stack Setup ## Objective Scaffold a containerized local development ecosystem connecting an Express backend to a Dockerized PostgreSQL instance via Prisma or Sequelize, with automated version-controlled migrations and a verified health endpoint. --- ## Phase 1 — Capability Check & ORM Selection **Check your environment first:** - Do you have filesystem write access? Can you run shell commands? - If **yes**: execute commands directly and report outputs. - If **no**: print every command and file content verbatim; ask the user to run them and paste results back. **ORM Selection Rules (strictly in order):** 1. If the user explicitly writes `Sequelize` (case-insensitive) → use Sequelize. 2. If both ORMs are mentioned or the request is ambiguous → ask: *"Which ORM do you prefer: Prisma or Sequelize?"* 3. Otherwise → default to **Prisma**. **Record your state.** Create or update `.claude_history/setup_status.md` with: - Chosen ORM and framework - DB connection string template - Checklist of phases (unchecked at start, checked as you complete them) --- ## Phase 2 — Structural Scaffolding Run or print these commands in order: ```bash # 1. Confirm Docker docker --version docker compose version # or: docker-compose --version # 2. Init npm (skip if package.json already exists) npm init -y # 3. Install runtime dependencies npm install express # 4. Install ORM dependencies # For Prisma: npm install @prisma/client && npm inst
