[node:stream/iter](https://nodejs.org/docs/latest-v25.x/api/stream_iter.html#iterable-streams)), OpenTelemetry support, how to deal with AI contributions to Node, libuv v2, and more. Wu and Cheung (Node.js Project) **IN BRIEF:** - Node 20 _(Iron)_ has just entered [End-of-Life (EOL).](https://nodejs.org/en/about/eol) With this, _all_ LTS Node releases can run TypeScript without flags via type stripping. - [Electron 42](https://github.com/electron/electron/releases/tag/v42.0.0) has been released and no longer downloads the Electron binary in a `postinstall` script due to recent supply chain attacks using that vector. It now downloads itself dynamically the first time it's_run_. - Due to Temporal API support being provided by a Rust library ([temporal_rs](https://github.com/boa-dev/temporal)), [building Node 26+ from _source_ requires a Rust toolchain.](https://github.com/nodejs/node/blob/main/BUILDING.md#building-nodejs-with-temporal-support) [Rolldown 1.0: The High Performance JS Bundler](https://voidzero.dev/posts/announcing-rolldown-1-0) — It’s stable, fast, production-ready, and you get esbuild-like speed with Rollup plugin compatibility. Recent Node versions already handle `.ts` files, ESM, and JSON imports natively, so Rolldown’s real win is in _shipping_, when you want the smallest tree-shaken runtime artifact possible. The VoidZero Team 💡 [tsdown 0.22](https://github.com/rolldown/tsdown/releases/tag/v0.22.0), a library bundler built on Rolldown 1.0, has also been released.

BM25, analytics & vectors — no Elasticsearch required. 📢 Node 26.1 Lands FFI Support [Node.js 26.1.0 (Current)](https://nodejs.org/en/blog/release/v26.1.0) quickly followed Node.js 26 with a single notable feature: **an experimental `node:ffi` module.** FFI ([Foreign Function Interface](https://en.wikipedia.org/wiki/Foreign_function_interface)) is a mechanism to directly interface with libraries written in other languages (most commonly those exposing a C ABI). FFI support has been _complicated_ in Node over the years. [node-ffi](https://github.com/node-ffi/node-ffi) was an early option, but quite fragile. [Koffi](https://koffi.dev/) offers a more robust take on the idea and continues to work well today, but wasn't adopted as an official, core solution. Node settled on the [Node-API / NAPI approach](https://nodejs.org/api/n-api.html) of writing glue code to bridge the Node / C++ gap, an approach that's now universal in Node libraries with native dependencies. With [this work](https://github.com/nodejs/node/pull/62072) now in Node 26.1 behind a `--experimental-ffi` flag, it seems we're finally getting a core, officially supported FFI solution. It integrates with Node's [permissions model](https://nodejs.org/api/permissions.html) too (and [it's fast](https://github.com/nodejs/node/pull/63140)). Here's a basic (macOS only) example I just made to show off the basic shape of the support and how easy it is, though with only a single, simple call: --- ``` import { dlopen } from 'node:ffi'; const path = '/usr/lib/libSystem.B.dylib'; const { functions } = dlopen(path, { sqrt: { parameters: ['f64'], result: 'f64' }, }); console.log(functions.sqrt(2)); // 1.414213... ``` --- I also tried SQLite 3 with some success, and am looking forward to giving [Raylib 6.0](https://github.com/raysan5/raylib/releases/tag/6.0) a go as an example of a far more complex C library. My fingers are crossed that Node finds a way to make this stable, so we can all benefit from more direct use of native dependencies in Node in future 😄 **Got a link for us?** Reply and tell us.
