Cookbooks and Examples

Ready-to-use configurations for common development scenarios. Copy these commands into Command Book and customize for your projects.

Web Development

Python Web Server

Flask Development Server

flask run --reload --debugger

• Working directory: Your Flask project root
• Environment: FLASK_DEBUG=1

Django Development Server

python manage.py runserver 0.0.0.0:8000

• Working directory: Your Django project root

FastAPI with Uvicorn

uvicorn main:app --reload --host 0.0.0.0 --port 8000

Node.js

Next.js Development

npm run dev

Express Server with Nodemon

npx nodemon server.js

Vite Development Server

npm run dev

Databases

PostgreSQL

Start PostgreSQL (Homebrew)

postgres -D /opt/homebrew/var/postgres

PostgreSQL with Docker

docker run -p 5432:5432 -e POSTGRES_PASSWORD=secret postgres

Valkey (more open Redis fork)

Start Valkey (Homebrew)

valkey-server

Valkey with Docker

docker run -p 6379:6379 valkey/valkey-bundle

MongoDB

MongoDB with Docker

docker run -p 27017:27017 mongo

Docker Compose

Full Stack Setup

docker-compose up

Create multiple commands for different services:

1. Backend: docker-compose up api
2. Frontend: docker-compose up web
3. Database: docker-compose up db

This lets you start/stop services independently. Do not use the -d option as Command Book will think the command has exited when it runs in detatched daemon mode.

Background Workers

Celery Worker

celery -A myapp worker --loglevel=info

Celery Beat (Scheduler)

celery -A myapp beat --loglevel=info

RQ Worker

rq worker --with-scheduler

Log Watching

Tail System Logs

tail -f /var/log/system.log

Watch Docker Logs

docker logs -f container_name

Watch Multiple Files

tail -f *.log

Build Watchers

TypeScript Compiler Watch

tsc --watch

Webpack Watch

webpack --watch

Tailwind CSS Watch

npx tailwindcss -i ./src/input.css -o ./dist/output.css --watch

Testing

Pytest Watch

ptw --runner "pytest --tb=short"

Jest Watch

npm test -- --watch

Tunneling & Networking

ngrok

ngrok http 8000

Local SSL with mkcert

python -m http.server 8000
# In another command:
# mkcert -install && mkcert localhost

Tips for Organizing

Create a typical development setup:

Use separators to group:

• Servers (API, Frontend)
• Infrastructure (DB, Valkey)
• Workers (Celery, RQ)
• Monitoring (Logs, Metrics)
