Node.js often is thought of simply as a small but helpful tool for working with JavaScript code while developing applications. The two writers of (paid link) Node.js Design Patterns, 3rd Edition, however, show that Node.js is much more than a minor helpmate. They call it a major “innovation” in the challenging world of web development.

In their view, “the most important aspect of Node.js lies in its ecosystem: the npm package manager, its constantly growing database of modules, its enthusiastic and helpful community, and most importantly, its very own culture based on simplicity, pragmatism, and extreme modularity.”

Along with clear descriptions of how Node.js works, their updated and expanded third edition (paid link) offers “proven patterns and techniques” for designing and implementing production-grade applications using Node.js.

They delve into Node’s single-threaded programming model, its asynchronous architecture, and its deliberate emphasis on creating modules that do one thing well. And they describe how these approaches provide important benefits and advantages to developers who need to design applications that can be developed, tested, scaled, and maintained more easily.

In keeping with the “Node way” of application developement, their book lays out a ready-to-use “set of patterns to solve common Node.js design and coding problems.” The two authors discuss and illustrate how to write “scalable and efficient Node.js applications.” And they explain how to code in “modern” JavaScript, including “class syntax, promises, generator functions, and async/await.” They also point out differences between CommonJS and ESM (ECMAScript modules) and show how to handle those differences in Node.js.

If you develop applications using JavaScript, you may already have at least some basic experience with Node.js. Whether you are an experienced developer or just getting started, consider getting Node.js Design Patterns, 3rd Edition (paid link) and keeping it handy as an important reference source. It is well written and well structured. And, at 600+ pages, it covers a wide range of topics, from callbacks and events to messaging and integration patterns, plus more.
