"《单页Web应用：JavaScript从前端到后端》是由Michael S. Mikowski和Josh C. Powell合著的一本专著，由Manning出版社出版。这本书深入探讨了使用JavaScript构建大规模的单页Web应用（SPA）的全过程，涵盖了从浏览器端到后端的开发技术。书中不仅讲解了客户端开发，包括单页应用的架构、Shell模块、功能模块、Model模块、Data模块和Fake模块等，还涵盖了服务器端开发、Node.js、MongoDB数据库、内容分发网络（CDN）、搜索引擎优化（SEO）、数据分析、错误日志管理和缓存策略等主题。此外，附录部分提供了JavaScript编码规范和SPA的测试方法，适合有一定JavaScript、HTML和CSS基础的Web开发人员、架构师和产品经理阅读。" 该书首先定义了JavaScript单页应用的概念，并阐述了其与传统Web应用的区别。在客户端开发部分，作者详细介绍了SPA的架构设计，包括Shell模块作为应用的基础框架，功能模块负责具体功能的实现，Model模块处理数据模型，Data模块管理数据获取和存储，而Fake模块则用于模拟后端服务，便于前端开发和测试。书中特别强调了JavaScript编程的核心概念和技术，帮助读者巩固和提升JavaScript技能。服务器端开发方面，作者讲解了如何利用Node.js创建高效、可扩展的Web服务器，以及如何集成MongoDB作为后端数据库。同时，书中还涉及了如何优化SPA的性能，如利用CDN加速静态资源的加载，以及实施SEO策略以提高搜索引擎可见性。数据分析和错误日志管理章节为监控和改进应用性能提供了指导。缓存策略的讨论则涵盖了不同层级的缓存，包括浏览器缓存、服务器缓存和数据库缓存等，以减少延迟，提高用户体验。附录部分，作者提供了JavaScript编码的最佳实践，帮助开发者编写出高质量、可维护的代码。另外，关于SPA的测试方法也进行了详细说明，确保应用的稳定性和可靠性。《单页Web应用：JavaScript从前端到后端》是一本全面的实战指南，它将帮助读者掌握构建全栈JavaScript应用所需的技能，从构思到实现，再到优化和维护，全方位提升开发者的专业能力。

foreword

I wrote my first JavaScript single page web application (

SPA

) in 2006, although we

didn’t call it that at the time. This was quite a change for me. Earlier in my career I

had focused on low-level Linux kernel hacking and parallel and distributed comput-

ing, and the user interface was always a simple command line. After receiving tenure

at the University of San Francisco in 2006, I started an ambitious distributed comput-

ing project called River (http://river.cs.usfca.edu) that required an interactive graph-

ical interface to facilitate distributed machine management and debugging.

Alex Russell had just coined the term “comet” and we were inspired and deter-

mined to use this technology and the web browser for the interface. We had quite a

challenge trying to wrangle JavaScript to enable real-time interaction. Though we

were able to get something working, it wasn’t as effective as we had hoped. The chal-

lenge was that we had to develop just about everything ourselves, as the libraries and

techniques available today simply didn’t exist. The first version of jQuery, for example,

wasn’t released until later that year.

In July 2011, I was Director of Research at SnapLogic, Inc. (http://snaplogic.com)

when Mike Mikowski joined the company as

Architect. We worked together on the

team that designed the next generation data integration product. Mike and I spent

countless hours discussing core issues in software engineering and language design.

We learned a lot from each other. Mike also shared drafts of the book you’re now

reading and that is when I learned about his and Josh’s method of building

SPA

s. It

was clear that they had developed several generations of commercial

SPA

s and had

behind some of the most compelling illustrations in the book.

John J. Ryan, for his careful technical proofread of the final manuscript shortly

before it went into production.

All the reviewers, who provided detailed analysis of our writing and our code so

we could simplify and enhance it as needed: Anne Epstein, Charles Engelke,

The thousands of MEAP purchasers, conference attendees, and colleagues,

who challenged us to optimize the solutions presented in the book.

Mike would also like to thank

■

Josh Powell, for asking me to write this book. What a great idea and a wonderful

learning experience. Now can I have my life back, please?

■

Greg Benson, for writing the foreword, and reminding me that it isn’t spelled

“forward.”

Gaurav Dhillon, John Schuster, Steve Goodwin, Joyce Lam, Tim Likarish, and

others at the SnapLogic team, who understood the value of economy and ele-

gance of design.

Anees Iqbal, Michael Lorton, David Good, and others from the GameCrush

team. Product development at GameCrush wasn’t perfect, but it is the closest I

have ever seen.

My parents, for buying a computer and refusing to buy any software for it. This

was great motivation to learn how to code.

■

Everyone I forgot. Murphy’s Law, subsection 8, clearly indicates I have forgotten

someone very important but will remember them only after publication. For

this, I am truly sorry and hope you will forgive me.

Josh would like to thank

■

Mike Mikowski, for agreeing to write this book with me. I am so glad I did not have

to undertake writing an entire book on my own. Sucker! I mean...thank you.

■

Luca Powell, my brother, for having the courage to follow his dreams and build

a business and to be himself. He is an inspiration.

The rest of my family and friends, without whom I wouldn’t be the person I am

today.

John Kelly, for giving me the freedom to finish up the book and understanding

that these things take time. Wow, do they take time!

■

Mark Torrance, for mentoring me as I grew an experienced engineering team

and for giving me the freedom to begin writing this book.

■

Wilson Yeung and Dave Keefer, for pushing me to learn deeper in the web

stack. You’ve had a major impact on my career and software engineering knowl-

edge and experience.
