Struggling with unknown data in TypeScript? @valibot.dev parses it effortlessly: validate & transform via pipes, grab detailed issues with safeParse (no throws!), and optimize perf with the abortEarly config.

Simply add the `index.md` file to the context when prompting, and the AI will automatically read the relevant guide for any code modification. This should also help me review and merge pull requests much faster from now on.

This message is for all @valibot.dev contributors. I recently added prompts to the Valibot repository that can be referenced when adding a new API reference to the website, for example, using an AI agent. github.com/fabian-hille...

Latest AI SDK 6 beta supports the following validation libs:

Zod, Valibot, Arktype, Effect Schema

(Zod still needed for AI SDK-internal schemas)

We are part of Vercel's open-source program, which is covering our costs.

Hey everyone! Sorry for the instability of the @valibot.dev docs over the last two weeks. They should be working properly now. Our Vercel bill suddenly increased from a few dollars to over $300, so spent management disabled all services. I am in contact with @vercel.com.

Thank you!

I see. The idea behind my logo is that the field of forms are like little bricks that you can stick together. More over the two bricks also match the fact that Formisch is a modular library. You only import what use use. Everything will be removed in your build step.

Fabian Hiller @fabianhiller.com · 10d

Thank you! What do you mean by "more than one type of form"?

Fabian Hiller @fabianhiller.com · 10d

What do you think about the new logo I designed for Formisch? 🧱

Thank you for your 8,000 stars on @github.com for @valibot.dev!

Thank you Oluwawunmi for writing it!

Fabian Hiller @fabianhiller.com · 16d

This is maybe one of the best articles explaining the philosophy and design decisions of @valibot.dev. It's technical, yet still easy to read and understand! I recommend taking a look, especially if you are currently using other libraries, such as @zod.dev. dev.to/oluwawunmiad...

Understanding Valibot: How it Works and When to Use it

Discover how Valibot uses functional programming to deliver smaller bundles, faster validation, and better TypeScript support vs Zod and other libraries.

Writing tests is hard, and I'm lazy. I'd rather write a few invariants, and let fast-check fuzz test the rest.

That's why I built @traversable/valibot-test.

Here it is in action:
