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. Watch here: youtu.be/ucOxdYuhEwQ #NodeJS #JavaScript #VSCode #CursorAI #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
@OscarEd57221990 @NodeSource Muchas gracias por tomarte el tiempo ☺️
💚 Ayúdame a entender mejor a la comunidad de Node.js llenando esta mini encuesta ! 🥹✨ Hola querida comunidad de Node.js de habla hispana ! 👋🏼 Soy Teff, DevRel en @NodeSource y Software Engineer desde hace varios años. En mi rol actual, estoy buscando entender mejor qué temas les interesan a los desarrolladores Node.js, cuáles son los desafíos que enfrentan día a día y qué tipo de contenido les resulta más útil y relevante. Por eso preparé esta encuesta que toma menos de 3 minuticos en responder. Sus respuestas me ayudarían muchísimo a crear contenido más útil y relevante para la comunidad. Además, en NodeSource tenemos la oportunidad de trabajar muy de cerca con el ecosistema de Node.js a través de nuestra colaboración con la OpenJS Foundation, y contamos con un equipo conformado por contribuidores del core de Node.js, maintainers y especialistas que trabajan diariamente en temas relacionados con la plataforma. Por eso me gustaría aprovechar ese conocimiento para crear contenido que realmente aporte valor a la comunidad hispana y responda a los intereses y necesidades reales de quienes trabajan con Node.js todos los días. Tu aporte es demasiado valioso así que muchísimas muchísimas gracias !!! ✨ Comparte con tus Node.js Devs de confianza 😉 forms.gle/feQuUH7bpLLE6i…
Node.js 26 ya está aquí ! ✨🚀 ⚡ Temporal, nuevos métodos para Map, Iterator Helpers, mejoras en V8 y más novedades que llegan con Node.js 26. En este video de YouTube encontrarás las 6 funcionalidades que más me llamaron la atención de esta versión. ¿Cuál es tu favorita? Versión en Español: youtu.be/1pCp-N6RY6M English: Version: youtu.be/9xfcYP8THC4 #NodeJS #JavaScript #Node26
⚡ Our first monthly newsletter is here! This month's edition covers: • Node.js 20 reaching EOL • Node.js 26: Temporal, Undici 8, V8 14.6 & more • The launch of N|Solid for Code Editors • Google I/O 2026 • Claude Code & Anthropic + SpaceX • Insights from OpenAI's Head of ChatGPT & Codex • Web Summit Vancouver • NodeConf EU 👇🏼 Read the full newsletter linkedin.com/pulse/nodesour…
🎬 New video on our YouTube channel ✨ This time, we sit down with Adrian Estrada @edsadr — CTO at NodeSource, @openjsf Board Director, and organizer of @MedellinJS, @CityJSMedellin, @NodeConfCo and @jsconfco — to talk about the real challenges behind Node.js upgrades in production. We cover: • What the OpenJS Foundation actually does • Why Node.js upgrades become difficult in production • Common upgrade challenges in enterprise systems • How the FREE assessment tool helps teams prepare • Why NodeSource and OpenJS are working on this initiative together Watch now 👇🏼 youtu.be/PAxhDu2S76o More about the Node.js Upgrade Program: nodesource.com/upgrade
Comunidad de Node.js 💚📢 Quisiera conocer su opinión sobre las extensiones de VS Code para Node.js y, especialmente, sobre una nueva que lanzamos la semana pasada en @NodeSource 👀 Se llama N|Solid in the IDE y permite visualizar métricas, diagnósticos y runtime telemetry de aplicaciones Node.js directamente dentro de VS Code ⚡️ Por ejemplo: · detectar problemas del Event Loop, · analizar CPU profiles, · revisar heap snapshots, · y entender runtime events en tiempo real sin salir del editor. Me encantaría que la pudieran instalar, probar y contarme honestamente: · qué les parece útil, · qué mejorarían, · qué les gustaría ver, · o cómo encaja en su flujo de trabajo actual. Pueden dejar su comentario directamente en el hilo de este mensaje o, si prefieren, dejar feedback anónimo aquí 👉🏼 forms.gle/vYTVf2XyFXUUt2… Extensión: marketplace.visualstudio.com/items?itemName… Les agradecería mucho si pueden compartir esto con más Node.js Devs ! 😉🚀
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 today ⚠️🪦 Run this now: $ node -v $ npx is-my-node-vulnerable If you're still on 20… you need an upgrade plan. 👉🏼 nodesource.com/upgrade 🎬 youtu.be/F6fmzFIYDIs
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/previ… 🚀 nodesource.com/upgrade #nodejs #backend #NodeSourcePartner
