SCHEMA-EVALUATOR

---

v0.0.5 CHANGELOGS:

• generateSchema is now generate_schema for a uniform call convention.

---

DESCRIPTION:

• A powerful tool for evaluating, validate, sanitize JSON object.
• Schema-Evaluator requires a certain knowledge of Schema-Inspector.
• For basic knowledge and application for Schema-Inspector dependency, follow this link: http://atinux.github.io/schema-inspector/

What is the main purpose of Schema-Evaluator? Using Schema-Inspector outright was useful but we thought it needed some extra sanitation and validation functions for developers to use both for development and/or production. This tool takes the sanitzation and validation processes further by being able to:

• Automatically generate a templated SCHEMA Object by passing a JSON object into the generate_schema function. Extra configurations should be done by the developer; but most of the hassle by common objects and arrays are done by this function.
• Reports extra properties that were not indicated by the SCHEMA object by using the evaluate_clean function

---

USAGE EXAMPLE:

You may have the following options to see how it works:

• Execute "node test" inside the schema-evaluator; or...
• Follow the code on the following lines...

var evaluator = require('../lib/schema-evaluator');
 
var schema = {
        type: 'object',
        properties: {
            name: { type: 'string', minLength: 4, maxLength: 12 },
            age: { type: 'number', gt: 0, lt: 100 },
            id: { type: 'string', exactLength: 8, pattern: /^A.{6}Z$/ },
            site1: { type: 'string', pattern: 'url' },
            stuff: {
                type: 'array',
                minLength: 2,
                maxLength: 8,
                items: {
                    type: ['string', 'null', 'number'],
                    minLength: 1
                }
            },
            stuff2: {
                type: 'object',
                properties: {
                    name: { type: 'string'}
                }
            }
        }
    };
 
var jsonObject = {
        name: 'NikitaJS',
        age: 20,
        id: 'AbcdefgZ',
        site1: 'http://google.com',
        site2: 'http://google.com',
        site3: 'http://google.com',
        stuff: ['JavaScript', null, 1234, 'test'],
        stuff2: { name: 'sample', description: 'sample description'}
    };
 
var result_validate = evaluator.validate(schema, jsonObject);
console.log('RESULT VALIDATE ', result_validate);
 
var result_strict_evaluate = evaluator.strict_evaluate(schema, jsonObject);
console.log('RESULT STRICT_EVALUATE ', result_strict_evaluate);
 
var result_clean = evaluator.evaluate_clean(schema, jsonObject);
console.log('RESULT EVALUATE_CLEAN ', result_clean);
 
var schemaResult = evaluator.generate_schema(jsonObject);
console.log('RESULT JSON TO SCHEMA ', schemaResult);
console.log('ITEMS INSIDE stuff.items', schemaResult.properties.stuff.items);
