normalize-json

Terse syntax for validating and normalizing JavaScript objects in Node.

const nJ = require('normalize-json');

// a schema looks like this!
let validator = nJ({
    name: [String, 30], // a string with <= 30 characters
    age: [Number, 0, 100], // a number between 0 and 100, inclusive
    color: ['red', 'yellow', 'blue'] // must be one of these three values
});

// here's how we might validate/normalize an object
let obj = {
    name: ' Nigel   ', // this string will be trimmed!
    age: 23,
    color: 'blue',
    someUndefinedField: undefined // undefined fields will be stripped out
};

let result = validator(obj); // 'result' is a new object; 'obj' has not been changed
console.log(result); // { name: 'Nigel', age: 23, color: 'blue' }
