Zod prototype mismatch

Even though the Zod object constructor name created by Drizzle is ZodObject, it is not an instanceof ZodObject. This is causing an error in another library I am using that accepts ZOD objects. Since I've got Zod as a peer dependency, it should be expected that drizzle-zod is using that version when it creates a Zod objects? I could be off here. It appears that drizzle-zod has ZOD as a peer dependecy, but drizzle-orm does not?

drizzle-orm doesn't use Zod at all only drizzle-zod does one thing that might cause it is a monorepo setup, where you might potentially have different Zod installations in different packages

Cory•15mo ago

I don't have a monorepo Is this something that you guys can fix on your end? Or something I can tell to the package maintainer of the library I am using?

bloberenober•15mo ago

Honestly, I'm not sure. All I know is drizzle-zod uses Zod as peer dependency, so maybe the issue is with another library. Which library is that, btw?

Cory•15mo ago

Superforms They check whether it's a zod object via instanceof

bloberenober•15mo ago

which one? 🤔

Cory•15mo ago

https://github.com/ciscoheat/sveltekit-superforms I see they have, zod": "3.x" where as drizzle-zod uses "zod": "*" So that could be the issue

bloberenober•15mo ago

Well, * just means "any version"

Cory•15mo ago

Yea I am not an expert I just asked chat GPT lol

bloberenober•15mo ago

did you install Zod manually? also, which package manager are you using?

Cory•15mo ago

Yes. I am using pnpm

bloberenober•15mo ago

you can shed more light into the issue by checking which Zod versions do both drizzle-zod and superforms reference you can do that by trying to open the library contents inside node_modules and following the require('zod') reference in one of the js files once you do, pay attention to the resolved zod file path, as it will contain the resolved Zod version if those references from drizzle-zod and superforms resolve to different paths, that means those libs use different zod instances, hence the error there may be an easier option to check that (via pnpm cli, probably), but I'm not aware of it 😅

Cory•15mo ago

ok i'll check! It they are both using, zod@3.21.4 double checking though Not sure if this matters but some comments, I assume auto generated, in index.js in drizzle-kit reference zod@3.20.6 Seems like they are using same version Yea not sure

bloberenober•15mo ago

drizzle-kit doesn't matter, its runtime is separate

Cory•15mo ago

ah okay well yea it appears they are resolving to same locaiton node_modules/.pnpm/zod@3.21.4/node_modules/zod/index for both

bloberenober•15mo ago

does it work without superforms? if you do the instanceof check yourself? also, does superforms work without drizzle-zod?

Cory•15mo ago

let me check No it's false so it's nothing to do with superforms

console.log(schema instanceof ZodObject)

console.log(schema instanceof ZodObject)

If you check that with a schema created by drizzle-zod it will return false so it appears it's nothing to do with superforms

bloberenober•15mo ago

weird all I'm doing is literally returning z.object() can you try reinstalling node_modules?

Cory•15mo ago

sure Same thing

bloberenober•15mo ago

and just to be sure - if you create z.object() yourself, the instanceof check works?

Cory•15mo ago

uh let me check lol correct Here is one difference I notice If I created a zod object and hover

const exampleZod: ZodObject<{
    name: z.ZodString;
}, "strip", z.ZodTypeAny, {
    name: string;
}, {
    name: string;
}>

const exampleZod: ZodObject<{
    name: z.ZodString;
}, "strip", z.ZodTypeAny, {
    name: string;
}, {
    name: string;
}>

I get this : ZodObject<{ Where as if I hover over drizzle-zod created zodobject I get

(alias) const selectMenuSchema: z.ZodObject<{
    name: z.ZodString;
}, z.UnknownKeysParam, z.ZodTypeAny, {
    ...;
}, {

(alias) const selectMenuSchema: z.ZodObject<{
    name: z.ZodString;
}, z.UnknownKeysParam, z.ZodTypeAny, {
    ...;
}, {

notice, : ZodObject<{ vs : z.ZodObject<{

bloberenober•15mo ago

that's because you imported z yourself

Cory•15mo ago

ah okay

bloberenober•15mo ago

another thing could you verify you use latest versions of drizzle-orm and drizzle-zod? try running pnpm up -i --latest and see if either of them shows up

Cory•15mo ago

sure orm and kit do I updated, same error

bloberenober•15mo ago

Well, I'm out of ideas for now. The instanceof check works in a test inside drizzle-zod, but that's expected, since it always uses the same Zod version as the drizzle-zod itself. If you can create a reproduction repo, it might help to resolve this.

Cory•15mo ago

ok Will do done!
