JSON Validator

Yep, another JSON validator :D

Usage

Installation

$ npm install --save pxl-json-validator

Usage

const Validator = require('pxl-json-validator');

const validator = new Validator();

validator.addSchema('string-schema', { foo: _type: 'string' });
validator.addSchema('number-schema', { foo: _type: 'number' });
validator.addSchema('boolean-schema', { foo: _type: 'boolean' });
validator.addSchema('array-schema', { foo: _type: 'array' });
validator.addSchema('object-schema', { foo: _type: 'object' });

validator.validate({ foo: 'bar' }, 'string-schema'); // return { foor: 'bar' }
validator.validate({ foo: 2 }, 'string-schema'); // throw error "Parameter has to be a string"

validator.hasSchema('string-schema'); // Check if schema exists
validator.removeSchema('string-schema'); // Remove schema
validator.clear(); // Remove all schemas

You can use pxl-json-validator into navigator, but please use polyfill for ES6.
