Preface

[ 2 ]

intelligence part involve the true value of our work?

We might all have had trouble finding clues to mysterious bugs, or squeezed our head

thinking about how we can add new features to the existing code base. Some of us, with

experience and intuition built over the years, may directly come up with a design that’s not

bad. For these people, getting through the common design patterns can help gain

knowledge of what people have already catalogued over years in the industry or be better

understood when discussing software designs with others. For people who have less

experience, learning common design patterns may be a more straightforward approach to

creating code that’s beautifully designed.

What this book covers

Chapter 1, Tools and Frameworks, provides a brief introduction to tools and frameworks that

will be used through this book, including installing a TypeScript compiler, preparing an

editor, and a basic workflow.

Chapter 2, The Challenge of Increasing Complexity, starts with a simple server-client

synchronizing implementation; we then expand its features and see how things can gain

undesired complexity and how that complexity can be reduced.

Chapter 3, Creational Design Patterns, catalogs five common creational design patterns, the

Factory Method, Abstract Factory, Builder, Prototype, and Singleton patterns.

Chapter 4, Structural Design Patterns, catalogs seven common structural design patterns, the

Composite, Decorator, Adapter, Bridge, Façade, Flyweight, and Proxy patterns.

Chapter 5, Behavioral Design Patterns, catalogs five common behavioral design patterns, the

Chain of Responsibility, Command, Memento, Iterator, and Mediator patterns.

Chapter 6, Behavioral Design Patterns: Continuous, catalogs another four common behavioral

design patterns, the Strategy, State, Template Method, Observer, and Visitor patterns.

Chapter 7, Patterns and Architectures in JavaScript and TypeScript, takes a look at the patterns

and architectures that closely relate to the language (JavaScript or TypeScript) and its

application, including asynchronous programming, module organization, error handling,

permission abstraction, and so on.

Chapter 8, SOLID Principles, explains the well-known SOLID principles and how they can

benefit a project and keep it healthy over time.

Chapter 9, The Road to Enterprise Application, guides readers to build the complete workflow

of an application that is ready to scale, including testing and continuous integration.
