Se viene un cambio importante para la comunidad de @nodejs 🚀 El release schedule va a cambiar después de más de una década con el modelo actual. @_rafaelgss explica el porqué detrás de esta decisión y qué cambia para quienes usamos, mantenemos y construimos sobre Node.js.

The Node.js release schedule is changing ⚡ One major per year. Every major headed for LTS. And a new Alpha phase replacing the short-lived odd-numbered release line. In this new article, @_rafaelgss explains what’s changing, why Node.js is moving to this model, and what it means for developers and maintainers. One major a year. Every line is LTS. Nothing got shorter. Read 👇🏼 nodesource.com/blog/nodejs-r…

Our own @brycebaril sat down with @matteocollina from @platformatic for a great conversation on AI agents, production Node.js debugging, performance, and developer expertise. They dig into where AI is already useful, where it still needs human context, and what happens to developer expertise as more code gets written by AI. Big thanks to Matteo for joining us for such a thoughtful conversation. 💚 🎥 Full interview: youtu.be/Y04v0XQHhow 📖 Companion article: nodesource.com/blog/can-ai-a…

Node.js version numbers are finally getting simpler. 🚀 Starting with Node.js 27, the project is moving away from the odd vs. even release model. ✅ One major release per year ✅ Every major release becomes LTS ✅ Version numbers align with the calendar year The new release model makes it easier to know when to upgrade. The free Node.js Upgrade Program, built in collaboration with the @openjsf, helps you understand how to upgrade. Learn more and join for free: nodesource.com/upgrade #NodeJS #JavaScript #OpenSource

How do you know if your Node.js app has a memory leak? 👀 And more importantly... how do you find the exact line of code causing it? In this demo, I intentionally introduce a memory leak into a Node.js application and use N|Solid to: ✅ Detect memory growth ✅ Capture a Heap Snapshot ✅ Let AI analyze it ✅ Find the root cause ✅ Verify the fix All directly from VS Code, Cursor, and Windsurf.

How do you build a Node.js production debugging extension for VS Code, Cursor, and Windsurf in just a few weeks? 👀 In this episode of NodeSource Dev Sessions, Cesar Diaz shares how the team built the N|Solid Extension using AI-assisted workflows, MCP integrations, rapid iteration, and a lot of engineering decisions along the way. We discuss: ⚡ Building an extension without prior experience 🤖 Claude, Codex, Cursor & Windsurf workflows 🔌 MCP integrations 🏗️ Architecture decisions 📚 Lessons learned shipping with AI Watch here: youtu.be/0s_uEN8gCMM #NodeJS #VSCode #AI #TypeScript #MCP

Existe una extensión para VS Code que muestra tus agentes de Claude como personajes pixel art dentro de una oficina virtual. No tiene coste, es open-source y te permite ver exactamente cómo trabajan tus agentes en todo momento. 👀

Node.js 20 is EOL ⚠️ Check this now: $ node -v $ npx is-my-node-vulnerable Still on 20? You're running unsupported software. In production… that’s a risk 👇🏼 🎬 youtu.be/F6fmzFIYDIs 🚀 nodesource.com/upgrade

How many Node.js versions exist? Not one. At any moment: • Current • LTS • Maintenance • EOL All active at the same time. If you're in production… this matters more than you think 👇🏼 🎬 youtu.be/bXAnzhodlpM 📊 nodejs.org/en/about/previous… 🚀 nodesource.com/upgrade

If you're using Node.js in production… you need to understand this: LTS ≠ Current One is built for stability The other for innovation Using the wrong one → risk Here’s how to choose 👇🏼 🎬 youtu.be/QkBVFPNdqcg ⏳ nodejs.org/en/about/releases 🚀 nodesource.com/upgrade

If you're running Node.js in production… you NEED to understand EOL. No security updates. No bug fixes. Just growing risk over time. And this April → Node.js 20 reaches EOL. Here’s what that actually means 👇🏼 🎬 youtu.be/oUnXGdmJsrg ⏳ nodejs.org/en/about/releases 🚀 nodesource.com/upgrade
