sql-validator

sql-validator.js

A simple and light validator for Javascript Objects.

Install the library with npm install sql-validator

Supports 4 type of validations:

Validations

• dataType - (Supports most of Validation of chriso's Validator ) - isNumeric, isAlpha, isAlphanumeric, isBase84, isAscii, isBoolean, isDecimal, isEmail, isIp, isInt, isJson, isNull, isMongoid, isUrl etc. -

• isOneOf - checks if input is one of actual value

• lengthBetween - checks if length of string is between two values (min & max)

• valueBetween - checks if a number is between two values (min & max).

And along with these 4 validations one can add own custom validations. See below for Example Code.

Example Code:

var Validator = require('./');

// create & update are mode
var mandatoryMap = {
  create: ['id', 'string1', 'status', 'date', 'value'],
  update: ['id']
};

var addressValidator = new Validator(mandatoryMap);

// data to be validated
var address = {
  id: 17282,
  country: 'INDIA',
  status: 1,
  created_at: new Date()
}


// there are two way to create validation map
// 1)
var validationMap1 = {
  date     : addressValidator.check('should be a valid date').dataType('isDate'),
  age      : addressValidator.check().dataType('isNumeric').custom(even),
  string1  : addressValidator.check('length should be between 3 & 30').dataType('isAlphanumeric').lengthBetween({'min': 3, 'max': 30})
};

// 2)
var validationMap2 = {
  id: {
    dataType: 'isNumeric'
  },
  country: {
    'dataType':  'isAlphanumeric',
    'lengthBetween': {
      'min': 3,
      'max': 255
    },
  },
  status: {
    'dataType': 'isBoolean',
    'isOneOf': [0, 1]
  },
  created_at: {
    'dataType': 'isDate'
  }
};


var result1 = addressValidator.isValid(address, validationMap1, 'update');
var result2 = addressValidator.isValid(address, validationMap2, 'update');

Output

if valid

{ valid: true }

if invalid

{ valid: false, error: 'Validation Failure.', invalid_key: 'key' }

Add Custom Validation Code:

var even = function() {
  return function(actual) {
    return actual % 2 === 0 ? true : false;
  };
};

var evenValidator = {
  even: even
};

addressValidator.addValidations(evenValidator);
