TLD Enumerations

Lists of every IANA TLD in formats that can be natively compiled in various language targets.

A canonical list of TLDs in CSV format was used to generate the native formats.

Usage

The lists can be conveniently used in PHP or Node projects including this package.

Node

use npm to add the tld-enum package to your project
```
$ npm install tld-enum --save
```
add the module to your source
```
const tldEnum = require('tld-enum');
```

access the list by using the tldEnum.tldList array

const tldEnum = require('tld-enum');
tldEnum.tldList; //an array with every IANA TLD

The following example...

const tldEnum = require('tld-enum');

console.log("There are " + tldEnum.tldList.length + " IANA TLDs");

let tldCheck;

tldCheck = "com";
console.log("Is '" + tldCheck + "' a real TLD?");
if (tldEnum.tldList.indexOf(tldCheck.toLowerCase()) != -1) {
    console.log("  yes");
} else {
    console.log("  no");
}

tldCheck = "somethingWeird";
console.log("Is '" + tldCheck + "' a real TLD?");
if (tldEnum.tldList.indexOf(tldCheck.toLowerCase()) != -1) {
    console.log("  yes");
} else {
    console.log("  no");
}

Should produce the following output...

There are 1573 IANA TLDs
Is 'com' a real TLD?
   yes
Is 'somethingWeird' a real TLD?
   no

PHP

use composer to add the katmore/tld-enum package to your project
```
$ composer require katmore/tld-enum
```

access the list by using the \TldEnum\TldEnum::TLD_ENUM class constant array

<?php
require_once __DIR__ . '/vendor/autoload.php';
\TldEnum\TldEnum::TLD_ENUM; //an array with every IANA TLD

The following example...

<?php
use TldEnum\TldEnum;

require __DIR__ . '/vendor/autoload.php';

echo "There are " . count(TldEnum::TLD_ENUM) . " IANA TLDs\n";

$tldCheck = "com";
echo "Is '$tldCheck' a real TLD?\n";
if (in_array(strtolower($tldCheck), TldEnum::TLD_ENUM)) {
    echo "  yes\n";
} else {
    echo "  no\n";
}

$tldCheck = "somethingWeird";
echo "Is '$tldCheck' a real TLD?\n";
if (in_array(strtolower($tldCheck), TldEnum::TLD_ENUM)) {
    echo "  yes\n";
} else {
    echo "  no\n";
}

Should produce the following output...

There are 1573 IANA TLDs
Is 'com' a real TLD?
   yes
Is 'somethingWeird' a real TLD?
   no

Examples

List Formats

PHP: TldEnum.php

A PHP source file providing a class with a constant having an array value comprised of every IANA TLD.
JSON: tld-list.json

A JSON formatted array comprised of every IANA TLD.
JavaScript: tld-enum.js

An export module with a constant having an array value comprised of every IANA TLD.

Updating the TLD lists

bin/update-formats
```
$ bin/update-formats
```
This should be all you need to update all the list formats using the latest data from IANA.

It uses multiple "helper" scripts to generate the full set of native format lists.

The individual "helper" scripts do not need to be directly executed when update-formats runs successfully.
