OIBLIB

OIBLIB - Library for validating and generating Croatian permanent national identification number "OIB", it is a number of every Croatian citizen and legal persons domiciled in the Republic of Croatia.

It also supports checks for legacy "unique master citizen number" also known as "JMBG".

Installation

npm

$ npm i oiblib --save

yarn

$ yarn add oiblib

Example

const oiblib = require('oiblib');
const { validateOIB, validateJMBG } = oiblib;

// Valid OIB
console.log(validateOIB('00000000001')); // true

// Invalid OIB
console.log(validateOIB('00000000003')); // false

// Valid JMBG
console.log(validateJMBG('0101990360007')); // true

// Invalid JMBG
console.log(validateJMBG('0101990360005')); // false

const {
  validateOIB,
  validateJMBG,
  generatePossibleOIB,
  generatePossibleJMBG,
} = require('oiblib');

// Generate new valid OIB
const newOIB = generatePossibleOIB();
console.log(`Generated OIB: ${newOIB}, is valid oib: ${validateOIB(newOIB)}`);

// Generate new valid JMBG
const newJMBG = generatePossibleJMBG();
console.log(`Generated JMBG: ${newJMBG}, is valid jmbg: ${validateJMBG(newJMBG)}`);

const {
  transformStringToArrayOfDigits,
  calculateOIBControlNumber,
  calculateJMBGControlNumber,
} = require('oiblib');

const inputOIB = '1234567890'; // Note 10 digits
const OIBControlNumber = calculateOIBControlNumber(transformStringToArrayOfDigits(inputOIB));
console.log(`For first 10 digits of OIB: ${inputOIB}, the control number is: ${OIBControlNumber}`);

const inputJMBG = '010199036000'; // Note 12 digits
const JMBGControlNumber = calculateJMBGControlNumber(transformStringToArrayOfDigits(inputJMBG));
console.log(`For first 12 digits of JMBG: ${inputJMBG}, the control number is: ${JMBGControlNumber}`);

• See ./examples for more examples.

Note

OIB and JMBG are NOT numbers, you should consider both OIB and JMBG to always be a string, thus sending anything else than a string type to validateOIB or validateJMBG should return false.

calculateOIBControlNumber and calculateJMBGControlNumber are looking for array of numbers, in order to do "control number" calculation, for that you can use helper function transformStringToArrayOfDigits. It transforms '1234567890' to [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ]

Todo

• Fully support JMBG
  • Generate valid JMBG based on random date.
  • validateJMBG should check if parts of predefined digits are in range. (DD, MM, YYY, RR, BBB, K)
  • JMBG parsing to extract (DD, MM, YYY, RR, BBB, K)
  • Pass params to random JBMG generator to respect predefined options like (DD, MM, YYY, RR, BBB, K)
