Query validation with "valibot" creates string / array unions. #899
Comments
Hi @ajotaos Thanks. This seems to be a bug. |
Hi ZerNico! Can you take a look at this? |
I was able to get the types working by porting over the export type Hook<
T extends v.GenericSchema | v.GenericSchemaAsync,
E extends Env,
P extends string,
Target extends keyof ValidationTargets = keyof ValidationTargets,
O = {}
> = (
result: v.SafeParseResult<T> & {
target: Target
},
c: Context<E, P>
) => Response | void | TypedResponse<O> | Promise<Response | void | TypedResponse<O>>
type HasUndefined<T> = undefined extends T ? true : false
export const vValidator = <
T extends v.GenericSchema | v.GenericSchemaAsync,
Target extends keyof ValidationTargets,
E extends Env,
P extends string,
In = v.InferInput<T>,
Out = v.InferOutput<T>,
I extends Input = {
in: HasUndefined<In> extends true
? {
[K in Target]?: In extends ValidationTargets[K]
? In
: { [K2 in keyof In]?: ValidationTargets[K][K2] }
}
: {
[K in Target]: In extends ValidationTargets[K]
? In
: { [K2 in keyof In]: ValidationTargets[K][K2] }
}
out: { [K in Target]: Out }
},
V extends I = I
>(
target: Target,
schema: T,
hook?: Hook<T, E, P, Target>
): MiddlewareHandler<E, P, V> =>
// @ts-expect-error
validator(target, async (value, c) => {
const parsed = await v.safeParseAsync(schema, value)
if (hook) {
const hookResult = await hook({ ...parsed, target }, c)
if (hookResult) {
if (hookResult instanceof Response) {
return hookResult
}
if ('response' in hookResult) {
return hookResult.response
}
}
}
if (!parsed.success) {
return c.json({
target,
issues: v.flatten(parsed.issues)
}, 400)
}
return parsed.output
}) |
Cool! Can you create a PR with the code? We can work on the header matter after we merge the PR. |

Using the
vValidator('query', schema)
with an object schema with string keys like this:it should result on an inferred type like:
{ foo: string }
but the input type is allowing the following type to pass through:{ foo: string | string[] }
.This behavior is not consistent with
zod
