VDA

Create schemas to validate data.

Usage

const vda = require('vda-schema');
const validatePerson = vda.validator({
    name: vda.str(3, 20),          // must be a string between 3-20 chars long
     age: vda.optional.int(1, 100) // must be a whole number between 1-100
});

validatePerson({name: "trevor", age: -3}); // false
validatePerson({name: "max"});             // true
