Zod 4, a popular schema validation library, introduces significant improvements including enhanced performance in TypeScript, faster string, array, and object parsing, and reduced bundle size. New features include Zod Mini for front-end optimization, JSON schema conversion, a schema registry, and an interface for defining object types. Additionally, it provides validation for file instances, a global translation API for error messages, and prettier error printing.

Zod 4 is CRAZY

Didn’t we listen that there’s a better rust-based zod alternative, just a few weeks ago?

Nice looks like some great wins from Zod, and Zod mini looks great too 🙌🏻

I found valibot to be more compatible with react-hook-form last time I was trying out both valibot and zod. I found I preferred the DX of valibot over zod too. I wonder how this stacks up against valibot now.

Nice and important update. Thanks.

Vscode started lagging just in time… awesome
