Zod v4 Beta Support

[kylekirkby]

Hi all,

Any chance anyone has put any thought into supporting Zod v4 considering the awesome perf boost that v4 offers

It would be great to get this project a beta version out which implements the breaking changes introduced in v4.

Cheers!

Is this needed as Zod natively supports JSON schema now? https://v4.zod.dev/json-schema

I was hoping to use v4 to break away from the major/minor-lockstep versioning into actual semver, and refactor the entire project with some much needed breaking changes, but as tadhglewis mentioned the native support kinda makes that project moot. On the other hand, v4 is still in beta, and I'm not actually sure what level of customization etc. the built-in functionality offers. In other words, there might be a raison d'être for a separate library like this, but we'll have to wait and see.

In the meantime I won't be putting any of my time or energy into it.

It might be useful just as a compat step to make upgrading easier, i.e. it'd be nice to be able to upgrade Zod without upgrading all the places we currently use zod-to-json-schema (at the same time). But appreciate that's not exactly a strong motivation for you to put work in here.

I strongly encourage you to bump the version and continue maintaining this! Many people will want a hassle-free migration path, while also getting the perf benefits of Zod 4. The new z.toJSONSchema is a totally different set of options. I'm trying to keep it extremely minimal, and point people towardsoverride for the vast majority of customization needs.

Ultimately there aren't a ton of changes in terms of schema types & internal structure so I don't think a refactor would be too painful. 😅
