Formisch v1 is here. 🎁 A schema-first form library for 8 frameworks: React, Vue, Svelte, Solid, Angular, Qwik, Preact & React Native. ✅ One Valibot schema = types + validation ✅ Native performance across all 8 frameworks ✅ Headless — works with your existing UI ✅ Bundle size starts at just 2.5 kB

formisch.devAI Writes Forms Pretty Well; Here's Why We'd Still Hand It a LibraryDo you still need a form library if AI writes your forms? We gave ChatGPT and Claude the same prompt for a React sign-up form and read what came back.

Do we still need libraries such as @formisch.dev if AI agents write the whole code anyway? We think YES and share more about it in our new blog post: formisch.dev/blog/ai-writ...

New @formisch.dev release is out 🔥 ✅ Experimental support for @solidjs.com 2.0 ✅ Peer dependency updated to support @preactjs.com 11 ✅ Code updated for @qwik.dev v2 RC

Not all heroes wear capes... at least the @e18e.dev team doesn't. They’re on a mission to make the JS ecosystem lighter and faster. So we’re donating to them as part of our OSS donation program. They've already reduced node_modules size and made Node.js tooling much faster, and we appreciate it!

Thank you OpenAI for extending your support for Valibot and Formisch with 6 months of Codex

Zod’s bundle size grows with each release. Valibot will always stay below 1 kB for simple schemas and below 2 kB for more complex ones.

I never imagined seeing this one day. GitHub now shows 100K+ public repositories using @valibot.dev. I'm not sure how precise that number is, but it's a huge milestone either way.

3 Aug

Thank you to everyone who's built something with Valibot, contributed code, or recommended it to others. It means a lot.

1 Aug

Really cool to see Flue using Valibot throughout its API. Typed inputs. Typed outputs. End-to-end type safety. It is always exciting to see projects choose Valibot as a core building block. Thanks Fred.

@formisch.dev is now available for 8 frameworks. It uses no runtime adapter and incurs no abstraction tax. You can expect great DX, native performance, and a small bundle size. ⚡️

30 July

ChatGPT Web has migrated from Zod to Valibot. 📦 Bundle size reduction: 10+ kB ⚡ Valibot code actually used: ~1.9 kB Who else should consider migrating? 👀

formisch.devIntroductionFormisch is a schema-based, headless form library for React Native. It manages form state and validation. It is type-safe, fast by default and its bundle size is small due to its modular design.

Should we ship 🧱 @formisch.dev for Octane?

Dominic Gannaway@trueadm.dev

Happy to announce Octane – the successor to Inferno. React’s programming model, compiled. Hooks, Suspense and Actions, compiled ahead of time. No virtual DOM. No Rules of Hooks. No manually maintained dependency arrays. The compiler understands what your code. octanejs.dev

🧱 @formisch.dev seems pretty stable since we release v1 RC a few weeks ago. You should give it a try for your next form! We have lots of good guides on how to use it or migrate from another library in our docs.

🧱 Formisch for React Native is next on my list
