Signals represent a limited form of inter-process communication. When a signal is issued to a process, it will be interrupted and a signal handler will be executed. If there is no signal handler, the default handler will be called instead. This sounds a lot like asynchronous events in Node, and that’s exactly how signals are implemented; using process.on: Typing man sigaction in a terminal will di

I decided to write a little article to discourage an unfortunately common pattern in Node.JS modules (and browser JavaScript, to a lesser extent) that can boil down to these two examples: // A: function myFunction () { if (somethingWrong) { throw 'This is my error' } return allGood; } and // B: async Node.JS-style callback with signature `fn(err, …)` function myFunction (callback) { doSomethingAsy

Code Review is a series on DailyJS where I take a look at an open source project to see how it’s built. Along the way we’ll learn patterns and techniques by JavaScript masters. If you’re looking for tips to write better apps, or just want to see how they’re structured in established projects, then this is the tutorial series for you. I was recently looking for something in the source to Express, a

On this e-book we will analyze what makes Node a different proposal from all that is out there, why you should use it, and how to get started. It starts with an overview but quickly dives into the code, module by module. By the end of this book you should be able to build your own Node service producers and consumers, and also feel comfortable around the Node API and conventions. You will also be
