    backend setup stack

    Example session with this skill installed

    I need to start a new Node.js project. Set up a backend stack using Docker and Sequelize for a PostgreSQL database.

    • Read your context and instructions
    • Compiled the backend setup stack

    I have initialized your backend development stack. I configured Sequelize as requested, scaffolded the Express server, and verified that the PostgreSQL container is healthy and accepting connections.

    Local Backend Stack Initialized

    ComponentStatusDetails
    Node.jsInstalledVersion 18+ detected
    DockerRunningPostgres 15 container active
    ORMSequelizeConfigured with pg/pg-hstore
    DatabaseConnectedapp_db on port 5432
    Health CheckPassedGET /health returned 200 OK

    Created Files

    • docker-compose.yml: Defines the PostgreSQL service with health checks.
    • .env: Contains DB credentials and connection strings.
    • server.js: Express boilerplate with a Sequelize-backed health endpoint.
    • config/config.json: Sequelize database configuration.
    • .claude_history/setup_status.md: Detailed setup logs and phase checklist.

    Command Execution Log

    
# Started database container
docker compose up -d

# Waiting for PostgreSQL...
# pg_isready -h localhost -p 5432 -U postgres
# localhost:5432 - accepting connections

# Running migrations
npx sequelize-cli db:migrate

# Starting server
npm run dev

# Server on http://localhost:3000
# ✅ Stack is healthy

    Next steps

    1. Define your data models in the models/ directory.
    2. Run npx sequelize-cli model:generate to add new entities.
    3. Use docker compose logs -f db to monitor database traffic during development.

    About this skill

    Setting up a local development environment for a Node.js backend usually involves a tedious dance of Docker configuration, ORM boilerplate, and connection string debugging. This skill automates the entire process, providing a production-ready local stack in minutes.

    What it does

    • Automated Scaffolding initializes npm, installs Express, and configures either Prisma or Sequelize based on your project requirements.
    • Docker Orchestration generates a specialized docker-compose.yml with health checks and persistent volumes for PostgreSQL.
    • ORM Configuration bootstraps schemas, models, and migrations while wiring up .env files with proper connection strings.
    • Environment Verification executes a multi-step gate to ensure PostgreSQL is ready before running migrations and starting the server.
    • Health Monitoring creates a dedicated /health endpoint that pings the database to verify the end-to-end connection.

    How it works

    1. Selection: The agent detects your preferred ORM (Prisma/Sequelize) or defaults to Prisma.
    2. Infrastructure: It verifies Docker installation and generates the container configuration.
    3. Dependency Injection: The agent runs the necessary npm installs and ORM initialization commands.
    4. Validation: It boots the stack, waits for DB readiness via pg_isready, and runs the initial migrations.

    Frameworks & tools

    Node.js (>=18), Docker, Docker Compose, PostgreSQL 15, Express, Prisma, and Sequelize.

    Why this beats prompting it yourself

    Standard LLM prompts often hallucinate Docker networking issues or forget to wait for the database to be "ready" before running migrations, causing immediate crashes. This skill uses a strict phase-based execution model with built-in error mitigation for common port conflicts and permission issues.

    Use cases

    • Initializing a new greenfield Node.js microservice with a reliable local database.
    • Migrating a non-containerized legacy Node.js app into a Dockerized environment.
    • Repairing a broken local developer environment where ORM migrations are failing.
    • Rapidly prototyping API features with a persistent relational data store.

    Known limitations

    Requires local installation of Docker, Node.js, and npm. It is strictly designed for local development environments and does not generate production Kubernetes or Cloud formation templates.
