I tried, and tried but can't figure it :(

This is the object I need to validate:

let body = {
    greeting:
        {
            stringValue: 'Hello !',
            stringListValues: [],
            binaryListValues: [],
            dataType: 'String'
        },
    newsletterId:
        {
            stringValue: '123456789',
            stringListValues: [],
            binaryListValues: [],
            dataType: 'String'
        }
};

I need to validate that there is a greeting, and that is has key stringValue and that is not empty. Other values I don't care.

Also, for the second object newsletterId, and that also has key stringValue and that is not empty. Other values I don't care.

I have e up with checking only root object, with this schema:

const schema = {
    greeting: Joi.required(),
    newsletterId: Joi.required()
};

I read many examples, but I was unable to find none that has this type of structure.

Sorted by: Reset to default 5

lets define a schema :

const schema = Joi.object().keys({
    greeting: Joi.object({
       stringValue: Joi.string().required().empty(['', null]),
       stringListValues: Joi.array().items(Joi.string()),
       binaryListValues: Joi.array().items(Joi.binary())
    }).required(),
    newsletterId: // same as above
});

and test it like this :

Joi.validate(myObjectToTest, schema, function(error, cleanObject){
    console.log(error, cleanObject);
})
