Node excitement 😉
Congrats to @marcoippolito.dev on making it official: type-stripping in Node 25 is now declared to be stable 🎉
You can run: node index.ts
The capabilities have not changed since Node 24. This is purely a maturity indicator.

State of JS 2025
Christmas is only 3 months away, which means it is also time to take the State of JavaScript survey (again).
The more devs participate, the clearer the big picture will be in the end 🙌
Plus, you learn about features, libs, and frameworks you haven't heard before (or forgot about).

pnpm v10.16.0 adds "minimumReleaseAge", a setting for defining how long a version has to have been published before pnpm will install it.
A nice countermeasure against accidental installs of short-lived compromised packages before they get taken down. Not a 100% fix, but a great additional step!

Type stripping is enabled by default 🔥🔥🔥🔥
You can just run `node file.ts` without `--experimental-strip-types` flag.
This is a huge milestone

Exactly 1 year ago I opened the PR to add Type Stripping to Node.js.
After 1 year of testing on the v23 and v24 release lines, it's finally ready to be unflagged on v22

Say hi to @marcoippolito.dev (@ HeroDevs), Node.js TSC member & TC39 delegate. In “Yet Another Config File,” he walks through the long road to node.config.json, why it took years to land, and how it improves runtime config for modern Node.js devs.

This ecosystem compatibility solution was suggested by @joyeecheung.bsky.social and implemented by @marcoippolito.dev 👍

Node.js + TypeScript - The "real" launch?
Node 24.3 will have it built in
❌ No scary experimental warning anymore!
This warning made it really awkward to ship native TS in any serious Node app, so happy to see it removed!
