In this part we validate the data that comes from the client with Joi package.

If you want to have custom message with Joi you should use messages() method.
Example:
------------------------------------------------------------------------------------------------------------------------
const schema = Joi.object({
username: Joi.string().trim().min(3).max(100).required().messages({
'any.required': 'الاسم مطلوب',
'string.base': 'الاسم لازم يكون من نوع نص',
'string.empty': 'رجاء ادخال الاسم',
'string.min': 'لا يجوز الاسم يكون اقل من ثلاثة حروف',
'string.max': 'لا يجوز الاسم يكون اكثر من مئه حروف',
}),
});
