Nordic ID Validator
Nordic-ID-Validator
is a comprehensive toolkit for verifying Nordic personal identification numbers with accuracy and ease.
Features
- Supports all major Nordic countries: Sweden, Norway, Denmark, and Finland.
- Provides both format and date validation.
- Lightweight with no external dependencies.
Installation
Using npm:
npm install nordic-id-validator
Usage
First, import the Validator class:
const Validator = require('nordic-id-validator');
Next, create an instance of the Validator class:
const validator = new Validator();
To validate a personal number, use the isValid
method by passing the personal number and the respective country code:
const isValid = validator.isValid('your_personal_number', 'SE'); // For Swedish numbers
Replace 'your_personal_number'
with the personal number you want to validate and 'SE'
with the respective country code. Valid country codes are:
-
SE
for Sweden -
NO
for Norway -
DK
for Denmark -
FI
for Finland
Example:
const isValidSwedish = validator.isValid('123456-7890', 'SE');
console.log(isValidSwedish); // true or false based on the validity
const isValidNorwegian = validator.isValid('12345678901', 'NO');
console.log(isValidNorwegian); // true or false based on the validity
You can also validate a personal number without specifying the country code. In this case, the country is specified by the the function. For example:
const isValidSwedish = validator.isValidSE('123456-7890');
console.log(isValidSwedish); // true or false based on the validity
The following country-specific methods are available:
-
isValidSE
for Swedish SSN -
isValidNO
for Norwegian SSN -
isValidDK
for Danish SSN -
isValidFI
for Finnish SSN
Error Handling
The isValid
method will throw an error if an invalid country code is provided or if the input is neither a string nor a number:
try {
const isValid = validator.isValid('your_personal_number', 'INVALID_COUNTRY_CODE');
} catch (error) {
console.error(error.message);
}
