@rtorcato/api-validation

Zod request validation helpers with pretty error formatting. Pairs with @rtorcato/api-errors so validation failures surface as BadRequestError.

import { validate } from '@rtorcato/api-validation'
import { z } from 'zod'

const Body = z.object({ email: z.string().email() })

// throws BadRequestError('Error #1: ...') on bad input
const body = validate(Body, await req.json())

API

validate(schema, data)

formatZodError(error, options?)

Turns a ZodError into a single human-readable string. options are zod-error ErrorMessageOptions.
