Koa 3.0: The Expressive HTTP Middleware Framework — Koa first appeared over a decade ago as a ‘next-generation’ Web framework that shared some of the lineage (and team) of Express.js, but leaning on more modern JavaScript features and ideas of the time. While Express has been making a comeback recently, Koa has progressed too and offers a compelling alternative. v3.0 release notes.

IN BRIEF:
-
⏰ A reminder that Node.js v18 reaches its ‘End-Of-Life’ tomorrow! There is an ongoing commercial support option, but if you can upgrade to Node v22, now’s the time.
-
In related news, Node.js v23 is now in ‘maintenance’ mode with no planned further releases. v24 is due to land soon, though, and will become the new ‘Current’ release.
-
Bun continues with its march to Node.js compatibility with 100% of the Node.js tests for the
eventsmodule now passing. -
In other Bun news, Bun has a
llms-full.txtfile of plain text documentation that can be fed into LLMs to help you work with Bun using AI agents, etc. -
Vercel Functions that use Node.js can now detect cancelled requests and stop execution before completion.
The Node.js Test CI Security Incident Explained — The Node.js project recently experienced a critical security incident with its test CI infrastructure. Attackers exploited a flaw in the Jenkins pipeline and this post goes into detail about how it came about and was resolved.
Node.js Technical Steering Committee
Giving V8 a Heads-Up: Faster Startup with Explicit Compile Hints — Not Node specific but a look at a V8 optimization that may become relevant in time. Explicit Compile Hints let you direct V8 to eagerly compile specific files as a way to speed up startup. It ships with Chrome 136.

📢 Elsewhere in JavaScript
A roundup of some other interesting stories in the broader JavaScript landscape, in case you’ve missed them:
-
I’ve been dabbling with a little C# recently and enjoyed this TypeScript is Like C# guide oriented largely around showing TypeScript/JavaScript vs C# examples of doing the same things.
-
I was intrigued to see this experiment of using DuckDB-WASM from JavaScript to create a basic ‘3D’ game. This sort of integration could easily be used for more practical data-processing ends.
-
The latest version of the popular creative coding library p5.js 2.0 was released recently – it’s being rolled out very slowly, though, as it’s such a major upgrade.
-
With Deno 2.3 just around the corner, the Deno team shared a few updates on recent Deno improvements.
-
If you want to create completely free software for others to use, static HTML and JavaScript is the best approach says Simon Willison.
-
You can now use JSR packages with pnpm and Yarn.
