Node.js Design Patterns: Design and implement production-grade Node.js applications using proven patterns and techniques

If you've ever been curious about how Node.js operates under the covers, in particular how asynchronous code runs, this is the book for you. The book is full of clear explanations and concise examples that help the reader understand the differences between synchronous and asynchronous code execution, when to use each, and how to avoid engineering in bugs that will be hard to reproduce and fix. It offers a collection of useful design patterns tailored to different use cases -- don't reinvent the wheel when you need to solve a Node design problem -- read this book! The direct and conversational tone of the book makes it a joy to read, so much better than many tech books that are the reading equivalent of eating dryer lint. The authors clearly know their subject matter well, and have a gift for sharing that knowledge through clear writing and a cornucopia of examples. The downloadable code examples are a must-have for anyone serious about writing production-ready Node.js code. This book is the first programming non e-book I've purchased in years, and I'm thrilled to have found it.

This is a really good book. If you use NodeJS, I would highly suggest it. Especially if you’re not already a senior developer. It introduced me new concepts but it really helped me get my code more organized and strategic through using proven design patterns . The author, Luciano is VERY good with NodeJS and is really a top tier developer and great teacher! We’ll worth the small price!!!

This a great book as far as Node.js is concerned. It helped in upgrading my skills. Shout out to the authors. The book was delivered in great condition by Amazon.

This book is amazing, in depth and super informative. If you really into nodejs you have to grab this book as soon as possible. The only complain I have is that the book is not loosely coupled. Every chapter is building on the previous one, which I find unnecessary. For example the last chapter, Messaging techniques shouldn't be coupled with the rest of the book.

An excellent book that covers many topics, including design patterns, with every example in JavaScript. The author does a great job of explaining each subject with multiple examples refactoring each into the optimal solution.

This book gets straight to the point, and there are many practical examples. You can find fundamentals and more advanced notions. Each chapter is well designed and the presentation of topics follows a well-structured logic.

If you are working with Node.js, do yourself a favor and make sure you get this. This book is OK can take you from bdgginer level to intermediate. It is amazing book, because it shows you the problem and the solution with a reference code. Tha. The authors ask a question and revile another problem with the implementation, and once again explain with a refeecode the solution.

Te enseña temas avanzados de Node.js y de programación en general. Los patrones de diseño se pueden utilizar en otros lenguajes por que este libro te enseña las bases para no estancarte en un solo lenguaje o framework.

This book is really good. When you read the title you think it might be GoF "Design Patterns" in Javascript and it will still be worth it. But it is so much more! * History and philosophy of NodeJS * Extensive deep dive of callbacks and promises and JS in general * You even make an universal app with NodeJS and React (which might cure your NextJS/Vercel fanboism and reduce your cloud bill) * Distributed systems * You also learn many state of the art npm modules for different tasks

Le livre couvre vraiment tous les sujets un peu compliqué sur Node.js, et possède systématiquement des exemples téléchargeables. Très pédagogique, grâce à ce livre, j'ai pu doubler mon niveau technique sur node.js !

Wonderful book for learning one of the most crucial aspects of programming Luciano Mammino and Mario Casciaro made the idea of ​​Design Patterns simple with Node.js. Simple and intuitive. From today I have two new idols 😊 👍🏻 .

Libro que siempre recomiendo a los desarrolladores junior o a los que quieran mejorar sus habilidades con Node. Bien estructurado y con el contenido necesario para entender como trabajar de forma profesional con este lenguaje.

If you are a serious Node developer (or hope to be), you must read this book. That's all there is to it. First off, the book's title seriously _undersells_ this book. It covers way, _way_ more than design patterns. Now, given how central Node is to ALL JavaScript development workflows these days (ie. anyone using Webpack/React, etc.), I'd strongly suggest anyone who writes JS in any serious way should read this book. For Node devs, again, it's a must. I had read the 2nd edition, and even so this 3rd edition was worth the read (they've updated everything for ES6, reorganized, and added a bunch of new material). The authors start at the fundamentals of how Node itself works (single thread, non-blocking I/O, etc.), then take a bottom-up approach to teach you not just Node, but the very fundamentals of asynchronous JS coding - going into great detail on each of the 4 core pillars of async JS code (events, callbacks, promises, and async/await). They completely explain the JS Module systems used in Node, explaining both CommonJS and ES6 modules, as well as the key similarities/differences of how they are loaded and execute at runtime (or bundle-time), where each type can/can't be used, how to use each type in Node, and so on. Even tho most Node devs may not use Streams much, this book does a whole chapter in fantastic detail to explain how they work, why they are so central to Node, and why that's such a strength of the platform. Of course they then explain a variety of example uses/patterns built on Streams, to drive the points home. The rest of the book is mostly design patterns from there. Each pattern is well explained, with ample example code and diagrams to clarify all you need to know. You may know all of them already (unlikely), but even if you do there are tips and tricks you can pick up along the way. Lastly, the final chapter is a rewrite (as I recall) of their prior coverage of messaging patterns, completely updated to reflect the growth and prominence of microservices. They give 75 pages to cover all the essential messaging patterns you'll probably need, and include numerous really solid (tho not prod-ready) examples using ZeroMQ, RabbitMQ, and even Redis Streams (which could apply to Kafka, etc. conceptually as well). OK, I'll stop gushing. I'll just close to say that coming in at over 600 pages, this book is a commitment, for sure. Once you start reading it, though, it flies by (I read it in a week). The writing is clear, the diagrams and code examples are great, and the value is self-evident. Buy it. Read it. Thank me later. ...You're welcome. ;-)
