Getting started

Even though all converted files are provided here, you might want to do it yourself.

You'll need Node.js, then cd into this folder and npm install.

Run npm run make to fetch and convert the latest registry, or you can supply a file path npm run make postnummerregister_ansi.txt to convert a local file (make sure it's the ANSI version).

You can also use it as a Node module. Just install it npm install norway-postal-codes and then require it in your code:

const postalCodes = require('norway-postal-codes');

console.log(postalCodes['1613']);
