If you‘ve spent any time in the Node.js community, you‘ve probably heard this piece of advice repeated ad nauseam: "Never run directly against Node.js in production." It‘s practically a commandment, handed down from the Node.js gods on high. But like many articles of faith, it‘s worth examining more closely. Is it always true? Are there…
Node.js makes it easy to quickly build web applications, thanks to its rich ecosystem of packages and frameworks like Express.js. However, as an application grows in size and complexity, it‘s critical to design the architecture in a way that will scale. Many Node.js applications start out with a flat file structure and simple routes. But…
As a JavaScript developer, you‘re probably familiar with the pain of "callback hell" – that tangled mess of nested callbacks that can quickly make your code unreadable and unmaintainable. Promises provide a cleaner, more composable way to handle asynchronous operations. But what if you‘re working with an API that still expects old-school callbacks? That‘s where…
As a full-stack JavaScript developer, I‘ve been using Node.js for several years now to build scalable back-end services and command line tools. Node has become an integral part of my development toolkit, so I‘ve always had an interest in understanding how it works under the hood and potentially contributing to the project.
