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, the latest release at the time of publication.
What You Will Learn:
-
Use Ruby's core classes and design custom classes effectively
-
Explore the principles behind variable usage and method argument
choice
-
Implement advanced error handling approaches such as exponential
backoff
-
Design extensible libraries and plugin systems in Ruby
-
Use metaprogramming and DSLs to avoid code redundancy
-
Implement different approaches to testing and understand their
trade-offs
-
Discover design patterns, refactoring, and optimization with Ruby
-
Explore database design principles and advanced web app security
Who this book is for:
If you already know how to program in Ruby and want to learn more about
the principles and best practices behind writing maintainable, scalable,
optimized, and well-structured Ruby code, then this Ruby book is for
you. Intermediate to advanced-level working knowledge of the Ruby
programming language is expected to get the most out of this book.
