Assuming I have a DiscriminatedUnion, is there a utility that could be used to determine what shape within that union an underlying piece of data would match, if any?

With
.refine() no longer being able to narrow a type in v4, how would I do that now?

Hi, I'm making a flashcards app where you can create user defined flashcards, and each flashcard can depend on the contents of another flashcard.
```ts
const FlashcardDeck = z.map(z.string(), z.object({
dependencies: z.array(z.string()),
contents: FormattedText,...
Solution:
```ts
const FlashcardDeck = z.map(z.string(), z.object({
dependencies: z.array(z.string()),
contents: FormattedText,
})).refine((deck) => {...

Hi everyone. I'm struggling with zod 4 and how it handles coercing values. This is my scenario:
I have a form that contains a "Port"
input that has a type of number.
AFAICT, the typing of this input's value is a string, so I need zod to coerce it to number in order to validate properly against this schema:...Solution:
Thanks @janglad - I ended up doing this:
...
z.coerce.number<number>()
z.coerce.number<number>()

Similar to the above, I have an
input element with a type of "number". How do I validate it's value as a number when using zod 4 in combination with react-hook-form? z.coerce's input type change to unknown seems to have made this more difficult.Solution:
Indeed the same thing. Also same answer 😄 Either omit the genrics completely (
@hookform/resolvers properly infers input/output now) or pass both input and output typessemajy - Hello! I'm sort of new to typescript a...
Hello! I'm sort of new to typescript and Zod and I'm at the point where I have types that were generated based on my mysql schema (using kysely-codegen). Of course I also want to validate types at runtime made from server requests. Is it really the best way that I manually create Zod schemas based on these types?
Solution:
In actuality I only need Zod primarily for input validation from sources I don't have control over, which also means primarily validating a version of an entity or "type" that is either for updating or selecting

Hi everyone, I just updated to zod
4.0.15 and everything's working well except for one last remaining file in my project.
I have a generic component, InputFormField, that can be imbued with a schema, i.e.:
```tsx
<InputFormField<typeof FormSchema>
control={form.control}...Solution:
Ahhh... wondering if this might be a

I found that
z.record evaluates non-enumerable property keys. I'm not sure whether this is a bug or expected behaviour. It was unexpected to me. I ran into this validating a MobX observable object using a z.record with z.string() keys. MobX adds non-enumerable symbol properties, which caused parsing to fail.
If it's a bug, I can open an issue on GitHub, but if it's intentional, I'll just adjust my expectations 🙂
This test demonstrates the problem....Svish - Does inference somehow work differently...
Does inference somehow work differently with v4 than v3?

:Wave_Doggo: Dependeabot has opened a PR to update us to 3.25.x, but ESLint is failing due to

3.25.13 fixed this, thanks

Hey! I just read Zod stable is coming out pretty soon - just wanted to know ultimately whats going to be the behavior for the case shown here?

I have the need to handle discriminatedUnion and enums with an "Unkown" option. Is there a way to do something like that in a native way?
```typescript
const Cat = z.object({ type: z.literal("Cat"), mood: z.string() });
const Dog = z.object({ type: z.literal("Dog") });...
Solution:
Thats fine, I guess either way, we need a bunch of dynamic code, if we like it to behave as desired.
I think within code generation we have some options, but nothing really streight forward. Thanks again....

Hi everyone, first time here.
I’m just wondering is there is a place to contribute to v4.zod.dev website.
Like if there is typos in the provided examples, what is the proper way to point it out?
...
Solution:
Hi, you need to fork the repo and then raise MR to the zod repo. All the work is being done under v4 branch (have a look on github) thanks for trying to contribute to Zod

:Wave_Doggo: I think this might be a Zod Q at this point rather than TypeScript itself -- I have a custom type that relies on
import() types. I've figured out how to partially preserve them when generating declaration files, but I'm still getting some unknowns included instead of references to the import() types.Solution:
Ahah!
