start and end date should be different for one year

Hi there I’m using Yup as a validator for one of my schemas

This is my code here for validating schema

            start: Yup.date()
                .max(new Date(), "Max date")
                .min(
                    new Date(new Date().setFullYear(new Date().getFullYear() - 120)),
                    "Min date")
                ),
            end: Yup.date().min(Yup.ref('start'), "End date shouldn't be same as start date"),

This works but I can add the same date for the start date and end date.

I want that end date to be different and higher than start date

Thanks a lot

Answer

You can try Yup.when to handle this,

It provides you a trigger on which field change the schema should be recomplied and schema object for handling validations

const validationSearch = Yup.object().shape({      
  start: Yup.date()
    .max(new Date(), "Max date")
    .min(
      new Date(new Date().setFullYear(new Date().getFullYear() - 120)),
      "Min date"
    ),

  end: Yup.date()
    // .min(Yup.ref("start"), "End date shouldn't be same as start date")
    .when("start", (val, schema) => {
      if (val) {
        const startDate = new Date(val);
        startDate.setDate(startDate.getDate() + 1);
        return val && schema.min(startDate, "Should beGreater than start date");
      }
    })
});
