It’s 3:00 AM. Your pager duty alert triggers. The load balancer is throwing 502 Bad Gateway errors, but your logs show the Node.js process is technically “running.”
Introduction # It is 2026. Node.js is no longer just the “new kid on the block” for handling I/O-heavy operations; it is the backbone of enterprise microservices, serverless functions, and high-traffic APIs worldwide. Yet, a surprising number of applications still crash in production because they were deployed with a “works on my machine” mindset.
It’s that time of year again. While the general public is fighting over smart toasters and 8K TVs, we backend developers are looking at something different: annual subscriptions.
High-Performance Image Processing APIs in Node.js # In the landscape of modern web development in 2025, handling media assets efficiently is no longer optional—it’s a requirement. Whether you are building an e-commerce platform, a social media feed, or a content management system (CMS), users expect images to load instantly and look crisp on everything from 4K desktop monitors to mobile devices over spotty 5G connections.
Generating PDFs is one of those requirements that inevitably lands on a backend developer’s desk. Whether it’s generating dynamic invoices, downloadable reports, or shipping labels, the ability to convert data into a portable, uneditable document is a staple of enterprise applications.
In the fast-paced world of backend development, the only constant is change. Your application’s data requirements today will almost certainly look different next month. This is where database migrations come in—they are the version control system for your database schema.
It is 3:00 AM. Your pager goes off. The checkout service is experiencing high latency, but the CPU usage is flat. The logs are a chaotic stream of text, and you have no idea which database query is hanging the event loop.
If you have been in the Node.js ecosystem for more than a week, you have likely stared into the abyss of a node_modules folder and wondered where all your disk space went.
Mastering Node.js Memory Management: A Deep Dive into V8 GC and Leaks # If you have been working with Node.js in a production environment for any significant amount of time, you have almost certainly encountered the dreaded FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory.
