Introduction # If you have been in the development game for more than a few years, you know the sinking feeling of a database crash with a stale backup—or worse, no backup at all.
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.
The era of managing EC2 instances for simple API endpoints is long behind us. By 2025, Serverless had firmly established itself not just as a utility for “glue code,” but as a primary architectural pattern for scalable, cost-effective Node.js applications.
Introduction # As we settle into 2025, the debate over backend technologies has shifted from “which is the most popular” to “which is the most efficient.” For years, Node.js has been the default choice for startups and enterprises alike due to its vast ecosystem and the ubiquity of JavaScript.
In the world of high-performance Node.js applications, the Event Loop is king. But it is also a jealous king—it demands to be free. If you block the Event Loop with heavy computational tasks, image processing, or third-party API calls during an HTTP request, your application’s throughput will plummet.
Configuration management is the silent backbone of any robust backend application. If you’ve ever accidentally committed an API key to GitHub or spent hours debugging why your application is connecting to the production database while running locally, this article is for you.
It is 2025. The internet is noisier than ever. Between aggressive SEO scrapers, AI training bots, and the occasional malicious DDoS attempt, exposing a Node.js API without protection is like leaving your front door wide open in a storm.
The era of the tightly coupled monolith is fading, but the challenge of distributed systems is rising. In 2025, building a backend isn’t just about handling HTTP requests; it’s about choreographing complex data flows asynchronously.
