Node.js — Wednesday, May 14, 2025 Security Releases Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.

⚠️ Security release pre-alert: We will release new versions of v20.x, v22.x, v23.x, v24.x release lines on or shortly after May 14, 2025, in order to address:

- 1 high severity issue
- 1 moderate severity issue

Details: nodejs.org/en/blog/vuln...

I’d love to do something like that but in person… kind of collab summit workshop

Happy to announce @nodejs v24.0.0 💚!

This release brings several updates, including the V8 13.6 and npm to version 11.

As a reminder, Node.js 24 will enter long-term support (LTS) in October, but until then, it will be the "Current" release

Check it nodejs.org/en/blog/rele...

ci: add support to test release candidates by RafaelGSS · Pull Request #6103 · fastify/fastify This is just an idea, but I think it would be interesting to be able to test Node.js release candidates, specially for semver-major versions

A handy way to test Node.js release candidates.

I suggest you have something similar in your test suite, so you can act before a semver-major release of Node.js gets out.

RafaelGSS - Twitch Node.js Core Development

I'm live on Twitch again!

I'm posting some shorts on Youtube/Instagram of my sessions teaching "How to contribute to Node.js core" on Twitch.

I’m almost sure there are projects for comprehensive stress test out there. Are you targeting http?

Yeah, these kind of tests is important to find saturation. I have never built something for this specifically

A stress test? This is not recommended as a benchmark methodology. The data produced by a stress test should not be compared as other factors will affect the result.

I think this should be considered as an infrastructure test instead.

Next Guinness is on you

I have just updated it. I forgot to push it publicly. It should be fine now.

With this release we have also issued the CVEs to EOL versions of Node.js

I was waiting for the global nodejs config to be decided.

node —config=node.json

😅

Twitch Twitch is the world

We'll have a second session of Node.js mentoring today! Join us via OpenJS Foundation Slack (nodejs-mentoring channel). See you all in 30 minutes.

Yes

⚠️The @nodejs.org project will issue a security release for versions 23.x, 22.x, 20.x, 18.x on or shortly after, Tuesday, January 21.

Performance work can be disproportionate.

@joyeecheung.bsky.social makes a one-line change to a build script to cure a 50% regression in startup time.

I wrote an alias to `npx` that sets the Permission Model node options. You can use it in the same way you use `npx` but, with Node.js Permission Model restrictions :)

Put this in your .zshrc/.bashrc
