Node.js Moves Toward Stable TypeScript Support with Amaro 1.0 — Amaro is Node’s official way to strip types out of TypeScript code so that Node can run it (though you can also use Amaro as a library, if you prefer). The 1.0 release is a key milestone on the way to moving TypeScript support in Node.js from experimental to stable in a release later this year. Sarah rounds up the entire story.

💡 If you want to dig deeper, Marco Ippolito ▶️ gave a talk called The Path to Native TypeScript at Node Congress 2025. By the end of it, you’ll know everything you need to know about how TypeScript support in Node works and what its limitations are.
pnpm 10.12 Introduces an Experimental Global Virtual Store — pnpm has long been prized for its speed and efficiency over npm. v10.12 takes things further introducing a ‘global virtual store’ that node_modules symlinks to, enabling projects to share dependencies without them being installed numerous times.

✂︎ Deep cuts from the queue
As it’s a quieter week than usual, we went back to look through our (extensive!) queue of items which hadn’t yet made it into the newsletter for one reason or another. Here are some of the things that jumped out at us:
-
FIGLet.js is a library that can use the FIGfont spec to render text using FIG’s ASCII-only textual forms (as above). There’s a live demo on the Web here. Might be useful for your next CLI tool?
-
Bloomberg’s Michael Molisani introduces us to Stricli, a framework for building CLI tools that’s used at Bloomberg. GitHub repo.
-
Pyodide is a WebAssembly-based Python distribution targeting both the browser and Node.js as runtimes.
-
Pavel Romanov demonstrates how you can do basic profiling of Node apps in VS Code.
