Implementing Date Serialization Workaround with Effect Schema in Elysia

const overrideJSONSchema = <T extends ZodType>(
  schema: T,
  toJSONSchema: () => unknown | undefined,
) => {
  schema._zod.toJSONSchema = toJSONSchema

  return schema
}

const datetime = z.union([
    z.iso.datetime(),
    z.date()
  ]);

export const zDate = overrideJSONSchema(
  z.codec(datetime, datetime, {
    decode: (isoString) => new Date(isoString),
    encode: (date) => new Date(date).toISOString(),
  }),
  () => z.toJSONSchema(z.iso.datetime()),
)
