Modules are one of the most powerful aspects of Node.js. Organizing your code into modules enforces best-practices. Examples include separation of concerns, code-reuse and test-ability. Publishing a module to the NPM registry is a great way to share your module with others, but we won't discuss that here. In this article, we will create a custom Node.js module for local use.

Over the past year, JavaScript has experienced a tremendous increase in versatility due in large part to the Node interpreter, which allows JavaScript to run locally. In this post, I’ll talk about Nw.js, which is a framework for building and compiling native desktop applications using JavaScript, CSS, and HTML, and is powered by Node. I’ll start with the UI of a simple file monitoring application...

Why Do You Need CORS? Web developers encounter the Same Origin Policy when they need to use resources in more than a single domain. Modern applications leverage CDNs, APIs and services hosted on multiple domains, so developers often need to be able to bypass the Same Origin Policy restrictions. Developers working with nodeJS and other JavaScript frameworks may need to expose resources in an...

Get Over JSON: Implementing Protocol Buffers with Node.js and ProtoBuf.js There's a better alternative to the ubiquitous JSON as the communication protocol of the web. It's Protocol Buffers (protobuf). In a nutshell, protobuf offers a more dense format (faster processing) and provides data schemas (enforcement of structure and better compatibility with old code). Protocol Buffers were introduced...

Command Line Node

Wirtten on 06/01/2016, by Aaron Shirk | Comments

Command-line Node.js... bye bye bash? If I had to guess if node.js would every replace bash as a scripting language, I'd have to guess no. Needless to say, it's a very powerful scripting language used and loved by many. I certainly understand that. That said, bash is a bit arcane in its syntax, it's not very easy to learn, and unless you're a die-hard Unix guru or devops...

I’ve been writing express apps for about four years. In this blog post, I’ll share some of the best practices when it comes to security in Node.js express applications.

In my experience, it’s best not to rely on semver and version everything off exactly. I’ve...

Node.js is a solid resource for front-end tooling. In fact, it is not uncommon for a developer to first learn about Node.js in this context. Grunt, Gulp and Bower have contributed to the popularity of this front-end build ecosystem. This article provides an introduction to one of other strengths of Node.js: acting as a web server. I do not think any organization would base their enterprise on a...

This post is going to examine Ransom32, the first ransomware that is powered by JavaScript. JavaScript has been used for many years to attack by exploiting weaknesses in both Internet Protocol and Internet browsers. But despite its wide use for these nefarious purposes, the reach of JavaScript itself was limited to the browser, because it could not be run locally on a victim's machine. However,...
