Become an accomplished Ruby programmer by understanding the design principles, best practices, and trade-offs involved in implementation approaches to keep your Ruby applications maintainable in the long term

Key Features:

• Understand the design principles behind polished Ruby code and trade-offs between implementation approaches
• Use metaprogramming and DSLs to reduce the amount of code needed without decreasing maintainability
• Learn Ruby web application design principles and strategies for databases, security, and testing

Book Description:

Most successful Ruby applications become difficult to maintain over time as the codebase grows in size. Polished Ruby Programming provides you with recommendations and advice for designing Ruby programs that are easy to maintain in the long term.

This book takes you through implementation approaches for many common programming situations, the trade-offs inherent in each approach, and why you may choose to use different approaches in different situations. You'll start by learning fundamental Ruby programming principles, such as correctly using core classes, class and method design, variable usage, error handling, and code formatting. Moving on, you'll learn higher-level programming principles, such as library design, use of metaprogramming and domain-specific languages, and refactoring. Finally, you'll learn principles specific to web application development, such as how to choose a database and web framework, and how to use advanced security features.

By the end of this Ruby programming book, you'll have gained the skills you need to design robust, high-performance, scalable, and maintainable Ruby applications.

While most code examples and principles discussed in the book apply to all Ruby versions, some examples and principles are specific to Ruby 3.0, th
