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

validol({
	myProp: 1,
	myProp2: 2
}, ["myProp", "myProp2"]);

	},

	any: true
}
