The Many, Many, Many JavaScript Runtimes of the Last Decade — A meaty article (which took a year to put together) covering the myriad of JavaScript runtimes and engines both past and present, from obvious picks like Node.js to cloud platforms and lesser known ‘honorable mentions’. This is a great summary to round out your JS ecosystem knowledge.

Running LLMs in prod? Prompt logs ≠ monitoring — Trace full request lifecycle, track cost/latency/retries, monitor drift & RAG relevance. If you can’t answer “what changed & what did it cost?”, you’re flying blind. Read the blog to learn more.

IN BRIEF:
-
TypeScript 5.9 RC has been released, with the final release due later this week. Support for
import deferand the new--module node20feature are amongst the highlights. -
It’s early days but Google has unveiled OSS Rebuild, an attempt to make open source ecosystems (like npm) more secure by allowing the comparison of packages with upstream artifacts.
-
Attacks on the npm ecosystem have continued with the
ispackage getting hijacked through an npm-related typosquatted domain being used to phish login details.
The Node Developer’s Guide to Unix Domain Sockets — The TLDR: “Unix domain sockets deliver ~50% lower latency than TCP loopback for Node.js IPC.”
Pavel Romanov
▶ The Creator of Bun on Building Bun and Node.js Compatibility — A roughly half hour chat in which Patrick Akil speaks with Jarred Sumner, creator of Bun. “We intend for Bun to be a drop-in replacement for the existing Node.js ecosystem. Most of our engineering time is not actually spent on new features — it’s spent on Node.js compatibility”.
