+# psl (Public Suffix List)
+
+[](https://github.com/lupomontero/psl/actions/workflows/node.js.yml)
+
+`psl` is a `JavaScript` domain name parser based on the
+[Public Suffix List](https://publicsuffix.org/).
+
+This implementation is tested against the
+[test data hosted by Mozilla](http://mxr.mozilla.org/mozilla-central/source/netwerk/test/unit/data/test_psl.txt?raw=1)
+and kindly provided by [Comodo](https://www.comodo.com/).
+
+Cross browser testing provided by
+[
](https://www.browserstack.com/)
+
+## What is the Public Suffix List?
+
+The Public Suffix List is a cross-vendor initiative to provide an accurate list
+of domain name suffixes.
+
+The Public Suffix List is an initiative of the Mozilla Project, but is
+maintained as a community resource. It is available for use in any software,
+but was originally created to meet the needs of browser manufacturers.
+
+A "public suffix" is one under which Internet users can directly register names.
+Some examples of public suffixes are ".com", ".co.uk" and "pvt.k12.wy.us". The
+Public Suffix List is a list of all known public suffixes.
+
+Source: http://publicsuffix.org
+
+## Installation
+
+This module is available both for Node.js and the browser. See below for more
+details.
+
+### Node.js
+
+This module is tested on Node.js v8, v10, v12, v14, v16, v18, v20 and v22. See
+[`.github/workflows/node.js.yml`](.github/workflows/node.js.yml).
+
+```sh
+npm install psl
+```
+
+#### ESM
+
+From version `v1.13.0` you can now import `psl` as ESM.
+
+```js
+import psl from 'psl';
+```
+
+#### CommonJS
+
+If your project still uses CommonJS, you can continue importing the module like
+in previous versions.
+
+```js
+const psl = require('psl');
+```
+
+### Browser
+
+#### Using a bundler
+
+If you are using a bundler to build your app, you should be able to `import`
+and/or `require` the module just like in Node.js.
+
+#### ESM (using a CDN)
+
+In modern browsers you can also import the ESM directly from a `CDN`. For
+example:
+
+```js
+import psl from 'https://unpkg.com/psl@latest/dist/psl.mjs';
+```
+
+#### UMD / CommonJS
+
+Finally, you can still download [`dist/psl.umd.cjs`](https://raw.githubusercontent.com/lupomontero/psl/main/dist/psl.umd.cjs)
+and include it in a script tag.
+
+```html
+
+```
+
+This script is bundled and wrapped in a [umd](https://github.com/umdjs/umd)
+wrapper so you should be able to use it standalone or together with a module
+loader.
+
+The script is also available on most popular CDNs. For example:
+
+* https://unpkg.com/psl@latest/dist/psl.umd.cjs
+
+## API
+
+### `psl.parse(domain)`
+
+Parse domain based on Public Suffix List. Returns an `Object` with the following
+properties:
+
+* `tld`: Top level domain (this is the _public suffix_).
+* `sld`: Second level domain (the first private part of the domain name).
+* `domain`: The domain name is the `sld` + `tld`.
+* `subdomain`: Optional parts left of the domain.
+
+#### Examples
+
+Parse domain without subdomain:
+
+```js
+import psl from 'psl';
+
+const parsed = psl.parse('google.com');
+console.log(parsed.tld); // 'com'
+console.log(parsed.sld); // 'google'
+console.log(parsed.domain); // 'google.com'
+console.log(parsed.subdomain); // null
+```
+
+Parse domain with subdomain:
+
+```js
+import psl from 'psl';
+
+const parsed = psl.parse('www.google.com');
+console.log(parsed.tld); // 'com'
+console.log(parsed.sld); // 'google'
+console.log(parsed.domain); // 'google.com'
+console.log(parsed.subdomain); // 'www'
+```
+
+Parse domain with nested subdomains:
+
+```js
+import psl from 'psl';
+
+const parsed = psl.parse('a.b.c.d.foo.com');
+console.log(parsed.tld); // 'com'
+console.log(parsed.sld); // 'foo'
+console.log(parsed.domain); // 'foo.com'
+console.log(parsed.subdomain); // 'a.b.c.d'
+```
+
+### `psl.get(domain)`
+
+Get domain name, `sld` + `tld`. Returns `null` if not valid.
+
+#### Examples
+
+```js
+import psl from 'psl';
+
+// null input.
+psl.get(null); // null
+
+// Mixed case.
+psl.get('COM'); // null
+psl.get('example.COM'); // 'example.com'
+psl.get('WwW.example.COM'); // 'example.com'
+
+// Unlisted TLD.
+psl.get('example'); // null
+psl.get('example.example'); // 'example.example'
+psl.get('b.example.example'); // 'example.example'
+psl.get('a.b.example.example'); // 'example.example'
+
+// TLD with only 1 rule.
+psl.get('biz'); // null
+psl.get('domain.biz'); // 'domain.biz'
+psl.get('b.domain.biz'); // 'domain.biz'
+psl.get('a.b.domain.biz'); // 'domain.biz'
+
+// TLD with some 2-level rules.
+psl.get('uk.com'); // null);
+psl.get('example.uk.com'); // 'example.uk.com');
+psl.get('b.example.uk.com'); // 'example.uk.com');
+
+// More complex TLD.
+psl.get('c.kobe.jp'); // null
+psl.get('b.c.kobe.jp'); // 'b.c.kobe.jp'
+psl.get('a.b.c.kobe.jp'); // 'b.c.kobe.jp'
+psl.get('city.kobe.jp'); // 'city.kobe.jp'
+psl.get('www.city.kobe.jp'); // 'city.kobe.jp'
+
+// IDN labels.
+psl.get('食狮.com.cn'); // '食狮.com.cn'
+psl.get('食狮.公司.cn'); // '食狮.公司.cn'
+psl.get('www.食狮.公司.cn'); // '食狮.公司.cn'
+
+// Same as above, but punycoded.
+psl.get('xn--85x722f.com.cn'); // 'xn--85x722f.com.cn'
+psl.get('xn--85x722f.xn--55qx5d.cn'); // 'xn--85x722f.xn--55qx5d.cn'
+psl.get('www.xn--85x722f.xn--55qx5d.cn'); // 'xn--85x722f.xn--55qx5d.cn'
+```
+
+### `psl.isValid(domain)`
+
+Check whether a domain has a valid Public Suffix. Returns a `Boolean` indicating
+whether the domain has a valid Public Suffix.
+
+#### Example
+
+```js
+import psl from 'psl';
+
+psl.isValid('google.com'); // true
+psl.isValid('www.google.com'); // true
+psl.isValid('x.yz'); // false
+```
+
+## Testing and Building
+
+There are tests both for Node.js and the browser (using [Playwright](https://playwright.dev)
+and [BrowserStack](https://www.browserstack.com/)).
+
+```sh
+# Run tests in node.
+npm test
+# Run tests in browserstack.
+npm run test:browserstack
+
+# Update rules from publicsuffix.org
+npm run update-rules
+
+# Build ESM, CJS and UMD and create dist files
+npm run build
+```
+
+Feel free to fork if you see possible improvements!
