Satpam

---

Satpam is a wrapper for some nodejs validator libraries, I made Satpam so it's easy to create custom validator with parameters and custom validation messages.

Installation

npm install satpam --save

Quick Usage

import satpam from 'satpam';

const rules = {
  name: ['required']
  officeEmail: ['email'],
  phone: ['required', 'numeric']
};

const input = {
  name: 'Sendy',
  title: 'Lord',
  officeEmail: 'invalid email',
  phone: 'hi there123'
};

const result = satpam.validate(rules, input);

if (result.success === true) {
  // valid
} else {
  // invalid
  result.messages.officeEmail.email === 'OfficeEmail must be email';
  result.messages.phone.number === 'Phone must be numeric';

  // or get all messages in array form
  result.messages.messageArray[0] = 'OfficeEmail must be email';
  result.messages.messageArray[1] = 'Phone must be numeric';
}

Satpam instance

Satpam has create method to create new validator instance.

• Each instance will have cloned validation rules and messages, so it's safe to add or override validation rule without affecting other validator instances or the global satpam validator.
• The cloned validation rules and messages will be based on the current state of the global satpam validator. See Custom Rules

import satpam from 'satpam';

const validatorOne = satpam.create();
const validatorTwo = satpam.create();

Available Rules

• required

• numeric

• email

• image

• alpha

• alphanumeric

• date

• dateFormat:<format, e.g. DD-MM-YYYY>

• dateAfter:<the date input format, e.g. DD-MM-YYYY>:<date after e.g. 'now' or 20-1-2015>:<offset>:<unit of time e.g. 'days'>

• dateBefore:<the date input format, e.g. DD-MM-YYYY>:<date after e.g. 'now' or 20-1-2015>:<offset>:<unit of time e.g. 'days'>

• url

• string

• nonBlank

• creditCard

• phoneNumber (Currently only supports Indonesia phone number)

• mobilePhoneNumber (Currently only supports Indonesia mobile phone number)

• maxLength:<length>

• minLength:<length>

• maxValue:<max value>

• minValue:<min value>

• memberOf:$1

• equal:$1

• notEqual:$1

• requiredIf:$1:$2

  var input = {message: 'hi!'};
  // `subject` is required if message equals `hi!`
  satpam.validate({subject: 'requiredIf:message:hi!'});
  

• taxId:$1 Currently only support indonesian tax id e.g. taxId:id

  Use object notation for defining this rule examples

• beginWith:$1

  Use object notation for defining this rule examples

• regex:$1:$2

  $1 is the pattern, $2 is the regex flags examples

Custom rules

Add custom rules globally, it will affect every Validator instance(s) that is created after the custom rules addition, but not the old instance(s).

import satpam from 'satpam';

// oldValidator will not have `must-be-ironman` rule, because it's created
// before we add the custom validation.
const oldValidator = satpam.create();

// The global satpam validator will always the most updated validation rules.
// After this statement, we can do satpam.validate({name: ['must-be-ironman']}, ...);
satpam.addCustomValidation('must-be-ironman', val => val === 'ironman');
satpam.setValidationMessage('must-be-ironman', 'Not ironman D:');

// With parameters
satpam.addCustomValidation('range:$1:$2', (val, ruleObj) => {
  return val >= ruleObj.params[0] && val <= ruleObj.params[1];
});

// If validation fails it will set message to:
// "PropertyName must between 0 and 30"
satpam.setValidationMessage('range:$1:$2', '<%= propertyName %> must between <%= ruleParams[0] %> and <%= ruleParams[1] %>');

// newValidator will have `must-be-ironman` rule because it's created
// after we add the custom validation.
const newValidator = satpam.create();

TODOs

• Better documentation.
• Add more validation rules.
• Validate file types.
