Basic Usage

import Validator from '@secture/validator';

const validator = new Validator();

const rules = {
  name: 'string',
  age: 'number',
  email: 'string'
};

// Returns array of errors, empty if valid
const errors = validator.validate(rules, data);

// Or use assert to throw on invalid data
try {
  validator.assert(rules, data);
  // Data is valid
} catch (e) {
  // Handle validation errors
}
