Limit and Offset Joi valdation

Question

How to check either both limit and offset are provided or none of them

limit: Joi.number().integer(),
offset: Joi.when('limit' ,{is: Joi.exist(),
                  then: Joi.number().integer().required()}),

//This is working if limit is provided check for offset 

Answer 1

Try with:

limit: Joi.when('offset', {
    is: Joi.exist(),
    then: Joi.number().integer().required()
}),
offset: Joi.when('limit', {
    is: Joi.exist(),
    then: Joi.number().integer().required()
})

Doing this, both fields will be required at the same time.

Answer 2

limit: Joi.number().integer(),
offset: Joi.when('limit', {
  is: Joi.exist(),
  then: Joi.number().integer().required(),
  otherwise: Joi.any().forbidden().error(new Error("need limit and offset both"))
}),

This is working
