Learning Node.js Design Patterns
Node.js has been the strongest catalyst for JavaScript adoption in the last decade. Few years ago, the term JavaScript was some sort of a synonym of browser APIs and adding interactions to websites. Nowadays, it’s nearly impossible to work on a project which does not have JavaScript targeting a server, desktop, cloud, mobile and many more. JavaScript is everywhere.
The language has evolved greatly in several ways: adding new features, syntax, types of target platforms but also in terms of emerging best practices. These are commonly known as design patterns. Having a notion and basic understanding of solving recurring problems is one of the most useful and reusable type of knowledge a developer may have.
One of the first and most prominent resources covering this topic was Addy Osmani’s Learning JavaScript Design Patterns. A free online book which has been updated through time to include the most frequently encountered patterns for the language in general.
However, Node.js is more than just JavaScript. Its APIs touch upon file system, server management and so many more than just the browser, so that there is clearly a need for a richer resource which can add up for the gaps of the target platform.
Packt’s Node.js Design Patterns is the best book in my opinion. Its concise and practical style expands on topics which even experienced developers can find enriching. For example, there is a chapter about module systems: ES6, CJS, etc. As developers we follow along code we see in open source projects or other good practices but you’ll be surprised how useful details you’ll learn after it.
Apart from the fundamental understanding for Node.js in particular, the 3rd edition has been updated to also include the now-modern async/await features which come after introducing callbacks of course :) (no gaps to be missed)
Not to mention the availability of the already popular creational, structural, behavior, etc. patterns.
Get the book! This is surely a level up for your JavaScript and Node.js career!
