Date String

How to validate date string and get the Date type at the end?

  deadline: v.pipe(
    v.string(),
    v.transform(d => new Date(d))
  )

You could use v.isoDate() to validate whether it's correct ISO8601 date

Thanks for your response, but here it doesnt work, it still thinks it's a string.

export const BoardDtoSchema = v.object({
  id: v.string(),
  title: v.string(),
  icon: v.picklist(ICONS),
  background: v.object({
    identifier: v.string(),
    url: v.nullable(v.string())
  }),
  columns: v.array(ColumnDtoSchema)
})

export const ColumnDtoSchema = v.object({
  id: v.string(),
  title: v.string(),
  order: v.number(),
  boardId: v.string(),
  cards: v.array(CardDtoSchema)
})

export const CardDtoSchema = v.object({
  id: v.string(),
  title: v.string(),
  description: v.string(),
  order: v.number(),
  columnId: v.string(),
  priority: v.picklist(PRIORITIES),
  deadline: v.pipe(
    v.string(),
    v.transform(d => new Date(d))
  )
})

  const validatedResponse = axiosValidators.validateResponse(
      BoardDtoSchema,
      response
    )

  validateResponse<I>(
    schema: GenericSchema<I>,
    response: AxiosResponse<unknown>
  ): AxiosResponse<I> {
    const validation = safeParse(schema, response.data)

    if (!validation.success) {
      throw new AxiosValidationError(
        response.config,
        response.request,
        response,
        validation.issues
      )
    }

    return { ...response, data: validation.output }
  },

During response validating it's giving me the error - Types of property 'deadline' are incompatible.
Type 'Date' is not assignable to type 'string'
It's still a string, even though ts is showing Date type, for valibot it's string-date

When i write deadline: v.string(), it doesn't give me any error, but i need clear defined Date, v.date() doesn't give any ts errors, but it doesnt work with database dates - Invalid type: Expected Date but received \"2025-05-10T01:20:52.048Z\
