Node.js Punycode

Node.js Punycode Module

Punycode is an encoding syntax that converts Unicode (UTF-8) strings into basic ASCII. This is essential for Internationalized Domain Names (IDN) ÔÇö letting domain names include characters from non-English scripts while remaining DNS-compatible.

Example: When you type a domain with non-ASCII characters in your browser, it is converted to a form like xn--maana-pta.com behind the scenes using Punycode.

Importing Punycode in Node.js

const punycode = require('punycode');

Note: The built-in punycode module is deprecated in newer Node.js. Use the userland package punycode from npm: npm install punycode.

1. punycode.decode(string)

Converts a Punycode ASCII string into Unicode.

console.log(punycode.decode('maana-pta'));

2. punycode.encode(string)

Converts a Unicode string into Punycode ASCII.

console.log(punycode.encode('some-unicode-string'));

3. punycode.toASCII(domain)

Converts a Unicode domain name into Punycode ÔÇö only the non-ASCII parts are converted.

console.log(punycode.toASCII('manana.com'));
// xn--maana-pta.com

4. punycode.toUnicode(domain)

Reverses the conversion ÔÇö turns a Punycode domain back into its Unicode form.

console.log(punycode.toUnicode('xn--maana-pta.com'));
// manana.com
