Sentry is once again a top open-source supporter

Also supporting independent media and newsletters like This Week In React

Without companies like these, I wouldn’t be able to carry on.

Thanks Sentry ❤️

[David Cramer @zeeg]

I am here once again to say “put up or shut up”

One million to open source this year, as we continue to give back to the ecosystem via the pledge.

More than half has gone directly to your favorite open source developers.

Hey, this tsrs port can also speed up oxlint 😄

👀 Have you heard of this new experimental React MCP?

Now officially documented here:
https://t.co/Jnz5Zn2dmJ

Technically, it's not really an MCP
➡️ registers a group of tools to Chrome DevTools MCP

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

Now also available in v24.22 😄

📦 Node 26.10 - Native support for throttle/debounce

I didn't expect this 😄
RIP lodash

TC39 proposal when?

[Jamie Birch @birch_js]

Announcing Expo Desktop v1! It supports creating apps from templates, Prebuild, CNG, "run macos" / "run windows" commands, and more! 🎉

… And I made a docs website to go with it! Link below.

Is this how Cloudflare's security will collapse? 🤪

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

@Neolectron Can totally see this happening 😆

One day, a visitor or robot will dance in a certain way in front of those and break the internet 😆

[Dane Knecht 🦭 @dok2001]

Internet Security starts with randomness… https://t.co/QHPvj5GFOs

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

@jaydenfyi yeah, and probably some of them in private codebases for fancy use cases too

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

👀 TS 7.1 content mappers

We finally have a decent way to import a JSON file as const in TypeScript, thanks to @jaydenfyi

Although it's still a workaround with trade-offs, it's a great improvement until we get an official solution.

[TypeScript @typescript]

TypeScript 7.1 Beta is now available! Now with a preview API, content mapper support, new features, and some great optimizations. Give it a try and give us some feedback! https://t.co/kBX6lDBo18

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

@rydgel @marckohlbrugge interesting

I remember 25 years ago on my warez / xdcc / script kiddie times, we used to hack servers to put movies on them

Then we patched them, so that other hackers like us couldn't take over "our servers" 😆

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

@marckohlbrugge Fun idea, worth trying 😄

TIL about the idea of benevolent worms

[Rydgel @rydgel]

@marckohlbrugge Yes we can, it’s called benevolent worm. Search Wikipedia.

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

TIL about the idea of benevolent worms

[Marc Köhlbrugge @marckohlbrugge]

if this PHP vulnerability allows remote code execution, doesn't that mean we can use the vulnerability to auto-patch all vulnerable servers?

[Seb ⚛️ ThisWeekInReact.com @sebastienlorber]

@codydotjs Yeah, looks like a quite useful speedup for type aware rules
