No queremos presumir, pero @teffcode va a dar una conferencia sobre esto en la JSCONFMX este 29 y 30 de octubre.
¿Ya tienes tu boleto? 🎟 Cómpralo acá: jsconf.mx/
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.

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. 💚

🇨🇴 Our hearts are with Colombia following yesterday’s devastating earthquake.
We’re incredibly grateful that our NodeSource team members and their families are safe, while many communities across the country are facing very real loss and destruction.
💚 To help, NodeSource is pledging 100% of our August revenue from all new, paid SaaS accounts directly to the Colombian Red Cross (Cruz Roja Colombiana) to support emergency relief efforts.
❤️ You can also donate directly here:

Every bit helps. Please share and support. 🙏

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.

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

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 👇🏼

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 👇🏼

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 👇🏼

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 👇🏼
