## Installation

### npm
```bash
$ npm i oiblib --save
```

### yarn
```bash
$ yarn add oiblib
```

## Example

````javascript
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

````

````javascript
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)}`);

````

````javascript
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
  - [x] 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)
