isZod

[alii]

Hi everyone, hope all is well.

I wondered if there was a method to check if something was a zod schema. I'm working with a complex signature right now for something and a value I have could be one of three things, a schema, a function argument or a zod schema. I was looking for something like z.isZod(something); but wasn't able to find it.

What would be the best way to do this?

You can easily check

z.ZodType is base class for all zod schemas so you easily can do

const schema = z.object({})
if (schema instanceof z.ZodType) {
// this is zod type
}

If you want more specific checks

if (schema instanceof z.ZodObject) {
// this is zod object type 
}

If you're looking create a Zod schema for ZodType, you can do this:

z.instanceof(z.ZodType);

An official method would be needed, as obj instanceof z.ZodType is just not working.
