N|Solid 26 is here! 🚀

Node.js 26 LTS support, now with N|Solid's built-in observability, diagnostics, and security insights.

With Node.js 26 now in LTS, N|Solid brings its runtime capabilities to the latest Node.js LTS release.

Get started: downloads.nodesource.com

🚀 A new chapter for Node.js is here!

Two important milestones for the Node.js ecosystem:

🟢 Node.js 27 Alpha is officially available! This marks the beginning of the new release model.

✅ Node.js 26 is now Long-Term Support (LTS)! Bringing another stable release to developers ents.

What's changing with the new release model?

→ One major release per year.
→ Every major version eventually becomes LTS.
→ A new Alpha phase for early testing and ecosystem feedback.

📖 Our very own @_rafaelgss, Node.js TSC member, explains what's changing, why the release model is evolving, and what it means for developers and maintainers.

🚀 2.5K downloads and growing!

More Node.js developers are bringing runtime intelligence directly into their development workflow with the N|Solid Extension.

Instead of waiting until production to investigate performance issues, developers can analyze:

→ CPU and memory erformance
→ Node.js runtime telemetry
→ Package security
→ Performance bottlenecks

And with the N|Solid Plugin, AI coding agents can use real Node.js runtime context to help investigate performance and security issues.

⚠️ Node.js 18 reached End-of-Life on April 30, 2025.

→ ~1 month after EOL: Node.js 18 was still seeing around 50M downloads per month.

→ 15 months after EOL: in July 2026, Node.js 18 still recorded 32.7M downloads, based on Node.js download statistics aggregated from the
That’s the important part: EOL doesn’t mean a version stops being used. It means the official support and security fixes stop while applications may continue running on it.

And we shouldn’t repeat the same pattern with Node.js 20, which reached EOL on April 30, 2026, or with any older release.

For production, Node.js recommends using supported LTS releases. Today, that means Node.js 24 (Active LTS) or Node.js 22 (Maintenance LTS).

Don’t wait until EOL to start planning your upgrade.

Have you ever copied a regex escape function from Stack Overflow? 😅

You probably don't need it anymore.

Starting with Node.js 24, JavaScript includes RegExp.escape(), making it easy to safely escape user input before creating a regular expression.

Less boilerplate. More ity function to maintain.

Wait... no more odd vs. even Node.js releases? 🤯

For years, the rule was simple:
🟢 Even versions → LTS
⚪ Odd versions → Current (short-term support)

Starting with Node.js 27, Node.js is simplifying its release model:

✅ One major release per year
✅ Every release becomes lign with the calendar year

It's one of the biggest changes to the Node.js release schedule in years.

What do you think? better than the old odd/even model?

Do you know why modern AI apps use AbortController? 👀

Imagine a user sends a prompt to an LLM 🤖

Two seconds later, they change their mind and submit a new one.

Without AbortController:
❌ The first request keeps running
❌ The model keeps generating tokens
❌ CPU, bandwidth, e being consumed

Even though nobody will ever read the response.

With AbortController:
✅ Cancel the old request
✅ Stop the stream
✅ Free resources immediately

Small API.
Big impact. ✨

We just launched the N|Solid Extension in the IDE at #WebSummitVancouver 🇨🇦.

For years, developers have been stuck in a broken workflow:

leave the IDE → open dashboards → investigate production → return to code → guess at a fix.

That context switching iggest bottlenecks in the AI era.

The N|Solid Extension in the IDE changes that by bringing live production telemetry and pre-commit validation directly into VS Code.

⚡ Live runtime telemetry in the IDE
⚡ AI-powered incident analysis
⚡ Pre-commit fix validation
⚡ One-click profiling & remediation

No more disconnected dashboards.
No more guessing.

3 things about observability you probably didn’t know:

1️⃣ Monitoring = you know what to look for
Observability = you discover what you didn’t know

2️⃣ More dashboards ≠ better debugging
They often hide the real issue

3️⃣ Data isn’t the problem
Context is
