Lists of every IANA TLD in various formats. The lists may be continuously updated using the included update utility that pulls the latest data from IANA.

• Node Usage
• PHP Usage

Because the lists are provided in universial CSV and JSON formats, they can be easily utilitized in most programming environments. Additionally, for convenience, some native programming language formats have also been provided.

• Node Usage
• More Node Examples
• PHP Usage
• More PHP Examples

• 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');
  console.log(tldEnum.list); //an array with every IANA TLD

  The following example...

  const tldEnum = require('tld-enum');
  
  console.log("There are " + tldEnum.list.length + " IANA TLDs");
  
  let tldCheck;
  
  tldCheck = "com";
  console.log("Is '" + tldCheck + "' a real TLD?");
  if (tldEnum.list.indexOf(tldCheck.toLowerCase()) != -1) {
      console.log("  yes");
  } else {
      console.log("  no");
  }
  
  tldCheck = "somethingWeird";
  console.log("Is '" + tldCheck + "' a real TLD?");
  if (tldEnum.list.indexOf(tldCheck.toLowerCase()) != -1) {
      console.log("  yes");
  } else {
      console.log("  no");
  }

  Should produce the following output...

  There are 1577 IANA TLDs
  Is 'com' a real TLD?
     yes
  Is 'somethingWeird' a real TLD?
     no

• js-demo.js Demo using the simple array of every TLD in JavaScript.
• js-desc-demo.js Demo using the TLD description hashmap in JavaScript.
• js-type-demo.js Demo using the TLD type hashmap in JavaScript.
• js-info-demo.js Demo using the array of TLD info hashmaps in JavaScript.

• use composer to add the katmore/tld-enum package to your project

  $ composer require katmore/tld-enum

• access the list by using the \TldEnum\TldList::TLD_LIST class constant array

  <?php
  print_r(\TldEnum\TldList::TLD_LIST); //an array with every IANA TLD

  The following example...

  <?php
  use TldEnum\TldList;
  
  echo "There are " . count(TldList::TLD_LIST) . " IANA TLDs\n";
  
  $tldCheck = "com";
  echo "Is '$tldCheck' a real TLD?\n";
  if (in_array(strtolower($tldCheck), TldList::TLD_LIST)) {
      echo "  yes\n";
  } else {
      echo "  no\n";
  }
  
  $tldCheck = "somethingWeird";
  echo "Is '$tldCheck' a real TLD?\n";
  if (in_array(strtolower($tldCheck), TldList::TLD_LIST)) {
      echo "  yes\n";
  } else {
      echo "  no\n";
  }

  Should produce the following output...

  There are 1577 IANA TLDs
  Is 'com' a real TLD?
     yes
  Is 'somethingWeird' a real TLD?
     no

• php-demo.php Demo using the simple array of every TLD in PHP.

• php-TldInfo-demo.php Demo using the array of TLD info hashmaps in PHP.

• JavaScript

  • list.js

    An export module with an array comprised of every IANA TLD.

  • desc.js

    An export module with an object containing a property for every IANA TLD and the corresponding TLD's "description" as the value.

  • type.js

    An export module with an object containing a property for every IANA TLD and the corresponding TLD's "type" as the value.

  • info.js

    An export module with an array comprised of "info" object elements of every IANA TLD.

All TLD List Formats can be updated with the latest data from IANA by using the TLD Update Utility.

$ bin/devel/update-formats.sh

• Node.js version 8.11 or higher.

• (Optional) PHP command-line version 7.2 or higher, to re-generate the PHP format files.

• The devDependencies from package.json must be available.

  • If tld-enum was installed in an outside project using npm, then the tld-enum dev dependencies must be installed manually, as in the following example:

    npm install async-request --save-dev
    npm install cheerio --save-dev
    npm install commander --save-dev
    npm install country-data --save-dev
    npm install countryjs --save-dev
    npm install csv-parse --save-dev
    npm install csv-stringify --save-dev
    npm install es6-promisify --save-dev
    npm install fs --save-dev
    npm install fs-extra --save-dev
    npm install md5-file --save-dev
    npm install pathinfo --save-dev
    npm install request --save-dev
    npm install tmp --save-dev

  • If tld-enum was installed in an outside project using npm, then the TLD Update Utility can be executed from the node_module directory, as in the following example:

    node_modules/tld-enum/bin/devel/update-formats.sh

usage:
  update-formats.sh [-h]|[-q][format file options...]

-h,--help: Print a help message and exit.
-q,--quiet: Print only critical messages.

format file options:
  --force-php: Creating the PHP format files is mandatory.
  --skip-php: Always skip creating the PHP format files.
  --skip-csv: Use existing tlds.csv and do not download new data from IANA.

Internally, the TLD Update Utility uses multiple "helper" scripts to generate the full set of native format lists. These individual "helper" scripts should not be directly executed except for development and troubleshooting purposes.
