🤟 Awesome Node: Over 500 Curated Packages, Resources and Links
It’s been more than four years since we linked to Sindre's handy resource, but it continues to get updates and tweaks (and, if you want, you can contribute a submission too – though the bar is quite high).

👀 Vitest 4.0 Released: The Vite-Native Testing Framework
The Vite-powered, Jest-compatible testing framework introduces visual regression testing, makes its ‘Browser Mode’ stable (for running tests in a browser directly), adds Playwright Traces support, and more. Still unsure? You can compare it with other test runners here.

🤟 Node.js v25.0.0 (Current) Released
The latest cutting edge version of Node has arrived with Web Storage enabled by default, JSON.stringify perf improvements, a new --allow-net option in the permission model, built-in Uint8Array base64/hex conversion, and WebAssembly and JIT optimizations. As shown in the diagram above, this means Node 24 will soon be promoted to being the 'active' LTS release and Node 22 will enter its 'maintenance' LTS phase.
