When the verification fails, can Zod Validator throw an exception instead of directly returning an error message?

[askorupskyy]

You can use the middleware for this. honojs/hono#960

[ktKongTong]

This can be handled by a wrapper function:

import {z, ZodSchema} from "zod";
import type {ValidationTargets} from "hono";
import {zValidator as zv} from "@hono/zod-validator";
export const zValidator = <
  T extends ZodSchema,
  Target extends keyof ValidationTargets,
>(
  target: Target,
  schema: T,
) => zv(target, schema, (result, c) => {
  if(!result.success) {
    throw result.error
  }
})

or another version that supports a custom hook

import {z, ZodSchema} from "zod";
import type { ValidationTargets, Env } from "hono";
import { zValidator as zv , type Hook} from "@hono/zod-validator";

export const zValidator = <
  T extends ZodSchema,
  Target extends keyof ValidationTargets,
  E extends Env,
  P extends string
>(
  target: Target,
  schema: T,
  hook: Hook<z.infer<T>, E, P, Target> = (result, _c) => { if(!result.success) throw result.error }
) => zv(target, schema, hook)
