Announcing my new book about A11Y! ♿ When I first started as a web developer I didn't know anything about best practices for UX Only after guidance from many wonderful people have I improved; I want to share that ☺️ A11Y is a basic right and improves products for us all 🚀

Shoutout @nickstermusic.bsky.social for their amazing modern reimaginings of classic sample-heavy songs. EG: www.youtube.com/watch?v=wlQC... (I've had this one on loop for hours at a time in the past) How they don't have a much bigger individual following is well beyond me.

Was looking for an alternative for cross-env's ability to do: ``` ENV_VAR=true some-cmd ``` Cross-platform and it turns out that it's supported in PNPM with a single setting! How handy! pnpm.io/settings/oth...

I am looking for my next career opportunity! I’m an engineering leader, consultant, author, and open-source maintainer. I've been VP of Eng, written books, get 20M weekly downloads on NPM, and more. Know of a role you think I'd be a good fit for? Book time on my cal or DM me: corbincrutchley.com

React 19.3 is out! Really hyped about Fragment refs and browser APIs. Cool to see ViewTransitions stable too. react.dev/blog/2026/09...

CHAT GPT YOU ARE SCARING ME

Vitest 5 is here! 🎉 - Big performance improvements (vm pools up to 53% faster, ~18% boost across the board including Browser Mode) - New builtin Trace View in Browser Mode - Nested projects support - New benchmarking API - New `vi.when` API - Better defaults - And a lot of bug fixes!

ICYMI, Nvidia bought Hugging Face today. I have concerns. Nvidia is doing better than anyone else to build out a wholesale ecosystem around AI. But they've historically been a poor host to open ecosystems. See: Linux support. I suspect HF Cloud to be Nvidia locked in 6 months.

I still cannot believe that PNPM can interactively upgrade GitHub actions the same way it upgrades other NPM deps. SO good! pnpm.io/cli/update#u...

Earlier this year I had the opportunity to help teach a bootcamp based on curriculum from my book and broader Playful content. Just a dream come true; a full-circle moment for me. I'm so grateful for everyone who helped out, and to our students for being part of our journey.

I think about `browser()`: react.dev/reference/re... And its `use`age the same way I think about `infer` in TS: `use(browser()) ~= Runtime<infer browserInfo>` It's a way to unwrap the inner value from another container with a built-in wait mechanism while it retrieves the info

Spent some cycles last night releasing CLI Testing Library v4. It's: - Using Trusted Publishing - ESM Only - Now allowing Ctrl+C style chords - Not throwing errors with most key usage github.com/crutchcorn/c...

There's a fairly new proposal to Git to allow a sparse clone using a single command syntax: ``` git clone --only=frontend,tests/frontend <repo> ``` Seems incredibly cool, I hope it goes somewhere: public-inbox.org/git/CALE2CrT...

TanStack Form v2 is now in alpha! 📝 It brings drastically improved performance, far more flexible validators, even stronger type safety, and more! We're excited to get it into your hands and to start testing it. Try it out & let us know your thoughts: tanstack.com/blog/announc...

Over the past few months, we've been working incredibly hard on @tanstack.com Form v2. We're working hard on getting an alpha your way (maybe even within the week 👀) but can already share some of the updates we recorded earlier this week. Check it out: www.youtube.com/live/eMBGraf...

Claude Mythos is GA!... Kinda. www.anthropic.com/news/claude-... They just announced Fable 5, a "Mythos class" model. It scores 80.3% on SWE bench vs Opus' 69.2%... The catch is that it's 2x the cost of Opus 5.8.

This week I joined Stord as the Senior Engineering Manager of their AI team! I wrote a "Working with Me" for my team & thought it'd be fun to share with the rest of you as well: playfulprogramming.com/posts/workin... I'm excited to join the team and scale us to the next level! To the future! 🥂

In @npmx.dev you can now view a package's changelogs currently only package's that use Github to host their releases or changelog.md are supported but support for others are planned

Finally! A way to pass Chrome debugging to any tooling, not just Antigravity. Can't wait to see its integration with tools like OpenCode: developer.chrome.com/docs/devtool...

I know/understand the ecosystem's qualms with Chrome's prompt API Today they introduced the WebMCP experiment which, on first glance, makes me think that this could serve as a more model agnostic prompt API support; offloading LLM to browser itself Seems neat developer.chrome.com/docs/ai/webmcp

Ooooh what, contrast-color() is newly available across browsers?!: https://webstatus.dev/features/contrast-color

Earlier May 11th, many TanStack Router/Start packages were compromised, but quickly mitigated. Here is a full post mortem on the incident: tanstack.com/blog/npm-sup...

We at TanStack just had a major attack against our Router packages. We have a postmortem out now explaining what happened and how we mitigated the response: tanstack.com/blog/npm-sup... No other TanStack packages outside of the Router monorepo were impacted

.@tanstack.com Form now supports Preact natively; no React compatibility mode needed! I'm grateful to @jovidecroock.com — one of the Preact maintainers — for helping create this port! tanstack.com/form/latest/...

I wrote about everything I've felt, feared, and experienced about using AI for code over the last few years, and my opinions on where we stand. It's the most personal thing I've ever written. And I'm putting it out there to share with all of you. blog.isquaredsoftware.com/2026/05/ai-t...

TanStack Form has hit 2M weekly installs!

Vue support in TanStack Form is going to get much better when Vue 3.6 drops. We just had a major blocker fixed through a merge upstream by @fuzzyma.bsky.social Excited for this one!

Your web prayers, answered. Coming soon. Amen.

Also, THIS happened!! 🤯

The most upvoted feature of TanStack Form is formally in development: github.com/TanStack/for... Yes, Form Groups are well on their way! I'm hoping to move quick on this one, but transparently our TODO list is a mile long to get this stable. Stay tuned!
