Node.js 22 Features You Should Be Using

"For production environments, achieving stability and performance is just the first step. True enterprise readiness requires superior visibility and control. This is where tools like N|Solid and N|Sentinel becomes indispensable. N|Solid offers deep insight into the Node.js runtime, allowing you to proactively monitor performance, manage memory, and squash memory leaks. Paired with N|Sentinel, you gain crucial security features and compliance measures that extend Node.js 22's inherent stability."

"Stable WebSocket Client (via ws module) Node.js 22 introduces a stable built-in WebSocket client, aligning it with the web platform standard. You can now create real-time connections without third-party libraries like ws or socket.io-client for basic use cases. const ws = new WebSocket('wss://example.com'); ws.onmessage = (event) => console.log(event.data); This feature reduces dependency bloat and makes it easier to write universal JavaScript that runs the same on the server and in the browser."

Node.js 22 has entered Long-Term Support (LTS), signaling stability and readiness for enterprise deployment. The release emphasizes dependency elimination, core performance optimization, and an improved developer experience. Built-in additions include a stable WebSocket client aligned with the web platform standard and a fully stable fetch() consistent with browser implementations, reducing the need for third-party HTTP and WebSocket libraries. The permission model continues refinement from earlier experimental versions. Enterprise readiness requires visibility and control beyond runtime stability; N|Solid supplies deep runtime insight for monitoring performance, memory management, and leak detection, while N|Sentinel adds security features and compliance measures that complement Node.js 22's stability.
