Node.js Delivers First LTS with require(esm) Enabled — It’s a modest milestone, but Node v22.12.0 (LTS) has been released and marks Node’s first LTS release with non-flagged support for loading native ES modules with require().

🖼️ wasm-vips: It's libvips, Compiled to WebAssembly — libvips is a popular, highly efficient image processing library written in C. You can use it via Sharp in Node.js, but this offers a more isomorphic route for use in Node, Deno, and modern browsers by way of WebAssembly. (There's a nifty online demo here.)
