Node.js 24 is the latest Long-Term Support release, and Node.js 26 is the Current release line. Node.js 18 and Node.js 20, meanwhile, have both reached End-of-Life (EOL). That should make the direction of travel obvious. Instead, Matteo Collina’s analysis of Node.js download data showed that even discontinued Node.js 12, 14, and 16 release lines were still generating tens of millions of downloads per month, highlighting how slowly the ecosystem moves away from unsupported versions.

For years, the Node.js community has typed the same command billions of times: It's probably the most frequently executed command in the JavaScript ecosystem. We use it to start new projects, add dependencies, update existing ones, or simply bootstrap a development environment. It has become such a routine part of our workflow that most of us no longer stop to think about what actually happens during those few seconds while npm fills node_modules.

A Node.js application can continue starting, accepting traffic, and passing health checks long after the runtime underneath it has become unsupported. That creates a dangerous assumption: In reality, “running” and “supported” are two very different states. A Node.js release is more than a JavaScript executable.

The N|Solid Extension and open-source N|Solid Plugin bring real Node.js runtime context into code editors and AI coding agents, helping developers investigate production issues, improve performance, and validate changes without breaking their workflow.

If you've ever updated a dependency, scanned your project for vulnerabilities, or opened a GitHub Security Advisory, you've probably seen something like CVE-2025-13465. For many developers, it's just another identifier attached to a security warning. Easy to ignore, especially when your priority is simply getting your application shipped. But that small reference represents something much bigger: it's the common language the software industry uses to identify and communicate security vulnerabilities.

Reaching a milestone is always exciting. Some milestones carry a deeper meaning. Today, we're proud to share that the N|Solid Runtime has surpassed 2 million downloads. The milestone reflects growing momentum, with downloads accelerating and putting us on track to nearly double last year's total. To us, this isn't simply a download count.

AI coding agents have quickly become part of the daily workflow for Node.js developers. Whether you're using Claude Code, Codex CLI, OpenCode, Antigravity CLI, or Pi Agent, these tools are great at generating code, explaining implementations, and automating development tasks. But debugging production systems is a different challenge.

Memory leaks are among the most frustrating production issues to investigate. At first, everything looks normal. Requests are processed successfully, users aren't reporting problems, and the application appears healthy. Then memory usage starts climbing. Garbage collection runs more frequently. Performance degrades. Eventually, the process becomes unstable or crashes altogether. Detecting a memory leak isn’t even half the battle.

npm v12 finally turns off automatic install scripts. That closes one door and leaves another wide open. I have spent years on the security side of the Node.js ecosystem, more recently as the primary contact for the OpenJS Foundation CNA, and now as the Node.js AI Security Engineer in Residence, a role supported by Alpha-Omega. Almost all of that work comes down to one question: can you trust the code you install? So I will say this plainly.

Earlier this year, our team launched the N|Solid Extension, a Node.js production debugging and observability tool designed for modern development environments. The goal was simple: help developers investigate production issues without constantly switching between dashboards, monitoring platforms, and their editor. Instead, runtime telemetry, diagnostics, security insights, and AI-assisted workflows could live directly where developers already spend most of their time.
