NodeSource

This week in the Node.js ecosystem 👇 🟢 Node.js 26.9.0 and 26.10.0 bring updates across FFI, node:bench, Web Workers, crypto, filesystem APIs, and performance tooling. 🤖 We also look at the hidden security risks of AI-assisted Node.js development, where correct code can still be built on the wrong runtime or dependency baseline. 🌎 Plus: NodeConf EU 2026 is next week, with Rafael Gonzaga joining Antoine du Hamel to talk about the future of the Node.js release model. Also inside: ⬢ AI agent and security updates from GitHub and Google ⬢ Upcoming Node.js community meetings ⬢ Resources for teams upgrading from End-of-Life Node.js versions 📬 Read the latest NodeSource Weekly: https://lnkd.in/eRktN7K6 #Nodejs #JavaScript #OpenSource #AI #DeveloperTools #NodeSource

Debug Node.js faster with better runtime context. ⚡ With N|Solid DevTools, developers can bring runtime visibility directly into the tools they already use. 🔎 N|Solid Extension Get live Node.js telemetry, diagnostics, security insights, CPU, memory, and event loop visibility directly in your editor. 🤖 N|Solid Plugin Give AI coding agents deeper runtime context so they can investigate what your application is actually doing — not just analyze the code. Your editor + your AI agent + your Node.js runtime. Less guessing. More context. Faster debugging.

AI can generate code that works. But what happens when the runtime, dependency version, or production baseline it chooses is already outdated? In our latest article, we explore a growing security challenge in AI-assisted Node.js development: correct code can still run on the wrong baseline. Drawing on insights from Rafael Gonzaga, NodeSource Principal Open Source Engineer and Node.js TSC member, we look at how runtime security continues evolving long after an application ships, why EOL Node.js versions change the security equation, and how AI is influencing both software decisions and vulnerability discovery. We also cover: 🟢 Why supported Node.js releases continue receiving security fixes ⚠️ How EOL runtimes can turn a valid application into a security risk 🤖 How AI can recommend outdated runtimes or vulnerable dependency versions 🔐 Why AI-assisted vulnerability discovery still requires expert verification 🧑💻 Why developer environments are becoming part of the attack surface 🛠️ How is-my-node-vulnerable can help validate your runtime against current security data AI can accelerate engineering, but it shouldn’t replace authoritative, up-to-date sources of truth.

Two weeks to go until #NodeConfEU 2026! 😱 We’re excited to bring the #Node.js community back together for 2 days of talks, great conversations, and plenty of time to connect with the engineers behind the tools you rely on. If it’s on your list but not on your calendar, now’s the time to add it. 📍 September 29–30, Bologna, Italy. Tickets: https://buff.ly/blFoEQE #NodeJS #NodeConfEU #JavaScript

🚀 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 behavior → Event loop performance → 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. If you’re working with Node.js performance, observability, or AI-assisted development, give N|Solid DevTools a try: 🌊 Windsurf: https://lnkd.in/enDtyYWX 💻 VS Code: https://lnkd.in/e4n3GGCb 🤖 N|Solid Plugin: https://lnkd.in/ehdkEH5n What Node.js performance issue takes the most time for you to diagnose? #NodeJS #NodejsPerformance #Observability #DeveloperTools #AI #SoftwareDevelopment

Great to see Rafael Gonzaga back on stage! 🚀 At ParaibaJS, Rafa shared insights into some of the recent vulnerabilities fixed in Node.js and the work happening behind the scenes to keep the ecosystem more secure. Always a pleasure to see our team sharing knowledge, connecting with the community, and helping move Node.js forward. 💚

N|Solid downloads nearly doubled in August. 📈 From 105,619 downloads in July to 209,052 in August — a 98% month-over-month increase. So far in 2026, N|Solid Runtime has surpassed 1.15M downloads, with more than 2.4M total downloads. But the more interesting story is in the version data: newer Node.js releases are gaining ground while older runtimes continue to remain active across real infrastructure. We took a closer look at what the data tells us about Node.js runtime adoption, modernization, and EOL usage.

103M downloads of an End-of-Life Node.js release isn’t a success metric. It’s a risk signal. Node.js 20 reached EOL in April, yet it still recorded more than 103 million downloads in July. In this week’s NodeSource Weekly: 🔐 New Undici security fixes, including a high-severity WebSocket DoS vulnerability ⚠️ Why teams are still running EOL Node.js — and why they should be planning an upgrade 📈 N|Solid reaches 1.15M downloads in 2026 🤖 What’s new across AI developer workflows 🌎 Upcoming JavaScript and Node.js community events Plus, a practical Node.js + AI tip using AbortSignal.timeout(). 👉 Read this week’s edition: https://lnkd.in/e_ambnji #NodeJS #JavaScript #OpenSource #Cybersecurity #AI
