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.

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

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

Thank you Oluwawunmi for writing it!

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:

What are "pipelines" in @valibot.dev?

ℹ️ A pipeline is a left-to-right chain of schemas and actions
ℹ️ Each step gets the previous step’s output and can validate and transform
ℹ️ The final schema’s output type is the last step’s output type
