"《TypeScript设计模式》是一本由Vilic Vane编著的专业书籍，旨在提升开发者的效率，探索TypeScript语言中的设计模式。这本书是Packt Publishing出版的作品，版权归属2016年的Packt Publishing，所有内容未经许可不得复制、存储或以任何形式传输。作者在编写过程中力求确保信息的准确性，但书中的信息并非无条件保证，不承担因使用本书造成的直接或间接损害的责任。 TypeScript是一种JavaScript的超集，它增强了JavaScript的功能并支持静态类型检查，使得大型项目的开发更加有序和高效。本书深入讲解了如何在TypeScript项目中应用诸如工厂模式、装饰器模式、策略模式、观察者模式、单例模式、以及依赖注入等常见的设计模式。通过学习这些模式，开发者可以更好地组织代码结构，提高代码的可维护性和复用性，同时避免常见的编程陷阱。在阅读本书时，读者将了解到每种设计模式的定义、适用场景、实现方式以及在TypeScript中的实际应用示例。此外，书中还可能包含对TypeScript特性如接口、泛型和类的深入理解和结合设计模式的使用。对于那些希望扩展JavaScript能力，并将其应用于现代Web开发的工程师来说，这是一本不可或缺的参考书籍。值得注意的是，尽管本书于2016年8月首次发布，但其内容始终与最新版本的TypeScript保持同步，以适应不断发展的技术环境。为了尊重版权，所有提及的商标信息都已按照相应的规范进行标注，但Packt Publishing并不保证这些信息的准确性。《TypeScript设计模式》是一本实用的指南，帮助开发者在TypeScript的世界里运用设计模式，优化开发实践，提高代码质量，是任何正在或计划使用TypeScript的开发者的宝贵参考资料。"

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.
