validating all parts of the request

[ryanleecode]

zod validation is sequential right now. Meaning if the headers are invalid it will fail-first and not return any information about other parts of the request that might be invalid. Also the zod error has no context about the origin. you cant tell if its from header, query, body, etc by default.

Hi @ryanleecode

zod validation is sequential right now.

Hono's Validator validates the specified content, param, header, query, etc. By sequential, do you mean when use multiple validators?

In that case, how about using a custom Hook?

app.get(
  '/posts/:id',
  zValidator(
    'param',
    z.object({
      id: z.coerce.number()
    }),
    (result, c) => {
      if (!result.success) {
        return c.json(
          {
            'error in': 'param'
          },
          400
        )
      }
    }
  ),
  zValidator(
    'query',
    z.object({
      page: z.coerce.number()
    }),
    (result, c) => {
      if (!result.success) {
        return c.json(
          {
            'error in': 'query'
          },
          400
        )
      }
    }
  ),
  (c) => {
    const { page } = c.req.valid('query')
    // ...
    return c.json({
    })
  }
)
