Node.js is not standing still - releases 24.9 (current) and 22.20 (LTS) brought a number of improvements for server development, working with workers, and debugging applications. Let's take a look at what exactly has changed and why it's really cool for production.
HTTP module: stability and convenience
Improved work with keep-alive: connections are managed more efficiently.
New API for managing timeouts.
More flexible header customization.
The result: less "crutch" code and predictable behavior in production.
Workers: multithreading is maturing
Faster transfer of binary data.
More stable operation of
SharedArrayBufferandAtomics.Improved support for ES modules.
Now it's a real tool for CPU-bound tasks.
Memory profiling: now without pain
Heap Snapshots directly from the code.
Better integration with Chrome DevTools.
Marking of objects for leak analysis.
Node.js applications are no longer a "black box".
Comparison of Node.js 24.9 and 22.20
Region | Node.js 22.20 (LTS) | Node.js 24.9 (Current) |
|---|---|---|
HTTP | Basic keep-alive improvements | New API for timeouts, flexible headers |
Workers | SharedArrayBuffer basic support | Optimized binary data transfer, Atomics stability |
