It pretty much works as you would expect except for the simplest case where you already have a domain as the input.

Obviously this is trivial to check against, but it'd be nice if this library "just worked"

How it currently works:

example.com
  =>
https://example.com
  => example.com
www.example.com
  => example.com
//example.com/protocol-relative
  => example.com
[email protected]
  => example.com
weird-protocol://example.com
  => example.com

How it would be nice if it worked:

example.com
  => example.com
https://example.com
  => example.com
www.example.com
  => example.com
//example.com/protocol-relative
  => example.com
[email protected]
  => example.com
weird-protocol://example.com
  => example.com

This is how i'm currently working around this, it's ugly but it works:

const extractDomain = require('extract-domain');
function domain_from_url(url) {
  try {
    return extractDomain(url) ? extractDomain(url) : url
  } catch (error){
    console.log(error)
    return url
  }
}

This array of URLS

["https://www.independent.co.uk/travel/news-and-advi…terdam-rome-venice-warsaw-dubrovnik-a8108096.html", "https://www.ipsf.org.il/?section=20", "https://timesofindia.indiatimes.com/blogs/voices/g…up-for-sustainable-tourism-in-a-post-covid-world/"]

returns this array of strings ["co.uk", "org.il", "indiatimes.com"]

The first two aren't working properly for some reason.

Example:
extractDomain('https://www.argos.co.uk/');

Expected result:
argos.co.uk
Current result:
co.uk

Possible solution:
Check against some good TLD list. For example: https://publicsuffix.org/list/public_suffix_list.dat

Thanks for the work - currently this can't be used with multi-part domain endings such as .co.uk or .com.au (and countless others).

I'm currently using this library to extract the domain of a website and I'm running into issues.

https://www.test.com returns test.com
https://test.com returns null

Expected result:
https://test.com returns test.com

EDIT: The TLD option is set to TRUE
EDIT2: When the TLD option is set to FALSE, everything works accordingly

I'm getting a require is not defined error. (Actually getting Error: You must install psl library, but the real error is just swallowed by the catch…).

This is probably because, this package defines an ESM entry point:

  "exports": {
    "require": "./dist/extract-domain.js",
   // here => 
    "default": "./dist/extract-domain.modern.mjs"
  },

But the file extract-domain.modern.mjs is using a dynamic require to get psl on demand here.

which ends up in the .mjs-file.

The thing is, require does not exist in Node ESM.

In other words: The file is stating I'm ESM, while using a CJS-only feature.

i looks like it doesn't work on this .co.ma

I tried to extract the domain from this username '[email protected]' and got a blank string but when i tried with '[email protected]' i got the domain part 'something.com'.

please make this one work for less than 5 chars too.

I'm using this library in a React Native project, but when upgrading to react-native: 0.69.1 and trying to compile android app (npx react-native run-android) I get the following error:

error Failed to load configuration of your project.
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports" in /my-project/node_modules/extract-domain/package.json

I could fix it by modifying the node_modules/extract-domain/package.json and replacing the exports property with this:

"exports": {
    ".": {
      "import": "./dist/extract-domain.modern.js"
    },
    "./package.json": "./package.json"
  },

But I didn't want to create a PR with this change because I guess I'm missing some things here.

not recognize http://localhost:8080

https://en.wikipedia.org/wiki/Second-level_domain

*.co.uk

extractDomain(["mother.com/q/s"])

Output should be: mother.com but instead it is mother.com/q/s.

I tried to import as per the library docs
import extractDomain from 'extract-domain';
And then use it like

const urls = await extractDomain("https://www.mydomain", {
 tld: true,
 });

but it throws
extractDomain.default is not a function

Also tried
import * as extractDomain from 'extract-domain';
And then use it like

const urls = await extractDomain.default("https://www.mydomain", {
 tld: true,
 });

But got the same error

The only way I was able to make it work was by doing
const extractDomain = require('extract-domain');
And then use like in the first case

I am using typescript 5.1.6

Hi,

There is a little bug: if the domain is an IP address (like http://127.0.0.1:port), it returns only 0.1 instead of the full IP address.

Best,
Xavier
