Philipp Fehre - JavaScript Domain-Driven Design

Philipp Fehre is a software engineer, conference organizer, speaker, and educator. Having seen many different applications as a consultant, he moved on to educate developers as an advocate of the NoSQL technology and is now working as a backend software engineer. He has also been a writer for the German Linux magazine in the past.

For years, he has been fascinated by the possibilities of JavaScript and followed Node.js from its beginnings, using it for research projects and production web services.

I'd like to thank my wife, Steffi, for her continuous support and for dealing with me spending my nights writing this. I'd also like to thank the reviewers for doing an awesome job of finding all the places where I could have done better. I hope I did justice to their efforts.

Vahagn Grigoryan is a senior web developer who is currently working at Learnship Networks. He has more than 10 years of full-stack application development experience, ranging from LAMP to frontend RESTful applications. He has worked for companies such as Lycos and Telegate, and is currently working at Learnship Networks. This is the first book that he has reviewed. He is married and has a 2-year-old son.

I'm happy to thank my parents for their consistent guidance and shiny presence on each step of my life.

Max Kirchoff built his first website in 1996 on a little hosting service called GeoCities. He was not only immediately fascinated by the ability to distribute information with a graphical interface, but was also frustrated with how difficult it was to do interesting things with those early web browsers. As time passed and the technology evolved, Max built more and more websites, eventually working as a consultant for e-commerce early adopter businesses and then with advertising agencies, building campaigns that were on the bleeding edge of the Web. Along the way, he has worked on everything from leading the implementation of service-oriented architecture to UX prototyping and a thousand things in between. JavaScript was never his favorite language, but after working with a friend who "loved JS," he also came around and saw the strength and flexibility it provided for building beautiful and powerful web applications.

Max currently works for Google, where he works closely with advertisment platform partners to inform and enhance their web interfaces for better user experience.

I'd love to thank my grandmother, who was a brilliant and inspiring rebel who broke all the rules and challenged every thoughtless barrier anyone put in front of her.

Michael Smith is a developer and consultant with 15 years of experience. He has worked in a broad range of industries, including banking, finance, e-commerce, and oil. He is passionate about delivering high-quality software that actually meets and exceeds the client's needs. To this end, he is an advocate of putting the business front and center when developing software and exploring ways to encourage better communication between all stakeholders in a project.

He is involved in various open source projects, including a line of business application framework called Bifrost.

Preface

Welcome to JavaScript Domain-Driven Design . For years, JavaScript has been stuck in the realm of making a website a little more interactive, but nobody would have thought about implementing whole applications in JavaScript. This has changed dramatically over the past few years, and JavaScript has evolved into this omnipresent powerhouse of a language that is present in almost every space of development.

This phenomenal growth has introduced many problems during development, which were previously unknown in the JavaScript world. Projects grow to very large codebases, many developers work simultaneously on these large codebases, and in the end, JavaScript is more often than not a vital part of the overall application. The good thing is that most of those problems have been solved before, and we, as JavaScript developers, can draw from the vast experiences gained over the years in other spaces and adapt them to work for us in JavaScript, leveraging JavaScript's unique flexibility along the way.
