Validol

Validol is an util that validates that object has defined props.

Arguments

  • object Object
  • props string || number || Object || Array
  • ?defaultValue
  • ?settings Object

Result

{
    error: false || Error,
    result: Object,
    all: Bool,
    any: Bool
}

The default object mutates validol

if you do not want to mutate the object, it is necessary to add a "mutation: false" in settings.

eg:

var obj = {
    myProp: {
        myProp3: 3
    }
};
validol(obj, {
    myProp: [
        {
            myProp2: "myProp4"
        },
        "myProp3"
    ]
}, undefined, { mutation: false });

Examples

validol({myProp: 1}, 'myProp');
/*
returned: {
    error: false,
    result: { myProp: 1 },
    all: true,
    any: true
}
*/

validol({}, 'myProp');
/*
returned: {
    error: false,
    result: { myProp: undefined },
    all: false,
    any: false
}
*/

validol({

    any: true
}

var obj = {

        myProp3: 3
    }
};
