Validation

Modelled on h3-zod, built on valibot. Each helper accepts a valibot schema or a plain object of schemas, which is wrapped in v.object.

import { useValidatedBody, useValidatedQuery, vh } from '@wervt/nuxt/server'
import * as v from 'valibot'

const body = await useValidatedBody(event, { title: v.pipe(v.string(), v.nonEmpty()) })
const { page } = await useValidatedQuery(event, { page: v.optional(vh.intAsString, '1') })

Throwing helpers

They return Promise<Output> and throw a 400 when validation fails. The error's data is valibot's flatten() result:

{
  "status": 400,
  "message": "Validation failed",
  "data": { "nested": { "title": ["Invalid length: Expected !0 but received 0"] } }
}

Safe helpers

useSafeValidatedBody, useSafeValidatedQuery and useSafeValidatedParams return { success: true, data } or { success: false, issues } instead of throwing.

vh

Schemas for values that arrive as strings.
