Hands-On Ruby on Rails

Build Real-World Apps with Ruby on Rails

From Command Line to Full Stack with Hotwire, APIs, and Secure Deployment

Whether you're a newcomer to Ruby or a developer ready to go beyond tutorials, Build Real-World Apps with Ruby on Rails is your step-by-step guide to mastering full-stack development the modern Rails way. Through a series of practical, thoughtfully structured chapters, you'll learn how to build dynamic, real-world web applications from scratch-without skipping over the command line, testing, or deployment.

Starting with Ruby essentials and command-line scripting, you'll quickly move into Rails fundamentals like MVC, routing, models, and ERB views. You'll gradually level up by building out an interactive TaskBoard app, integrating Hotwire for real-time updates, authenticating users with Devise, and securing data with Pundit. Along the way, you'll write tests with RSpec, configure background jobs with Sidekiq, optimize performance, and deploy your app with tools like Render, Heroku, or Fly.io.

Unlike fragmented tutorials, this book offers a coherent path from idea to production-ready app-with professional development practices and real code every step of the way.
