OpenTelemetry vs. Deep Runtime Telemetry: Which Is Better for Your Node.js Stack?

If you're running Node.js in production, you've likely heard the buzz around OpenTelemetry. It's the industry standard for observability, backed by major vendors, and it promises vendor-neutral telemetry collection across your entire stack. For many teams, it's a game-changer: finally, a unified way to collect traces, metrics, and logs without getting locked into a single vendor's ecosystem.

Understanding Node.js' New Signal Requirement for Security Reports

Node.js has updated its vulnerability reporting policy on HackerOne, introducing a minimum Signal requirement. This change aims to improve report quality, reduce operational noise, and better support the maintainers responsible for project security. Below is an explanation of why this change happened, how it works, and what it means for the security community.

January in Node.js: Releases, Security Updates, and What Actually Matters

January didn’t bring radical changes to Node.js, and that’s precisely why it was important. Instead of headline features, the first month of the year reinforced a clear direction for the ecosystem. Stability over novelty. Signal over noise. Security handled with context rather than urgency. For teams running Node.js in production, January delivered clarity. Here’s what actually mattered.

How to Build REST APIs with Node.js & Express

In today’s fast-paced digital environment, REST APIs have become the backbone of modern application development, powering seamless communication between clients and servers. For developers, understanding how to build efficient and scalable REST APIs is essential. This article unpacks the foundational steps of creating REST APIs using Node.js and Express, offering actionable insights for building dynamic server-side applications.

Resolved: GPG Signature Warnings on Debian 13 and Modern Ubuntu

If you’ve recently upgraded to Debian 13 (“Trixie”) or a newer version of Ubuntu and suddenly started seeing security warnings when running apt update (or apt update --audit), don’t worry. You didn’t do anything wrong. This is a side effect of a broader security change across modern Linux distributions. SHA-1 signatures are being deprecated, and repositories that still rely on them may now trigger warnings or audits.

CVE, CVSS, and the Mistake Most Teams Keep Making

Modern software systems are exposed to a constant stream of disclosed vulnerabilities. Thousands of new issues are published every year across operating systems, runtimes, libraries, and frameworks. Treating all of them as equally urgent is not realistic, and trying to do so often leads to ineffective security work. To manage this volume, the security community relies on two foundational mechanisms: CVE and CVSS.

A comprehensive guide to error handling In Node.js

If you've been writing anything more than "Hello world" programs, you are probably familiar with the concept of errors in programming. They are mistakes in your code, often referred to as "bugs", that cause a program to fail or behave unexpectedly. Unlike some languages, such as Go and Rust, where you are forced to interact with potential errors every step of the way, it's possible to get by without a coherent error handling strategy in JavaScript and Node.js.

Diving Into Reactive Programming in Node.js

Boosting the scalability of your backend applications often means rethinking how you manage asynchronous data. That’s where reactive programming comes into play: a paradigm that treats data streams as first-class citizens, allowing your code to respond to data changes as they occur. While Node.js wasn’t built with reactive programming in mind, libraries like RxJS and Bacon.js support that approach.
