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."

"1. 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."

"2. Built-in fetch() is Now Fully Stable While fetch() was added in Node.js 18, it's now fully stable and consistent with browser implementations. You can confidently replace packages like axios or node-fetch with the built-in API. const res = await fetch('https://api.github.com'); const data = await res.json(); One less dependency, faster cold starts, and full alignment with the web standard API for HTTP requests."

Node.js 22 has reached Long-Term Support (LTS), offering enterprise-grade stability and performance. The release emphasizes dependency elimination, core performance optimizations, and developer experience improvements. Native features include a stable built-in WebSocket client aligned with web standards and a fully stable fetch() API, reducing reliance on third-party libraries and improving cold-start performance. The refined permission model continues to enhance security controls. Production environments benefit from runtime visibility and control through solutions like N|Solid for performance monitoring and memory management, and N|Sentinel for security and compliance, extending Node.js 22's inherent stability for enterprise deployments.
