$ npm i --save extract-domain
# Install bun https://bun.sh/
curl -fsSL https://bun.sh/install | bash
# tests
bun test:watch
{ tld: true }
permit to get Top Level Domain like *.co.uk
ESM import
import extractDomain from 'extract-domain';
Examples
const urls = [
'https://www.npmjs.com/package/extract-domain',
'http://www.example.com:80/path/to/myfile.html?key1=value1&key2=value2#SomewhereInTheDocument',
'http://user:password@example.com:80/path/to/myfile.html?key1=value1&key2=value2#SomewhereInTheDocument',
'https://npmjs.com/package/extract-domain',
'ftp://example.org/resource.txt',
'http://example.co.uk/',
'this.is.my@email.com',
];
extractDomain(urls[0]); // npmjs.com
extractDomain(urls); // [ 'npmjs.com', 'example.com', 'example.com', 'npmjs.com', 'example.org', 'co.uk', 'email.com' ]
TLD support requires the optional dependency of the psl
library.
Examples
npm i --save-optional psl
const url =
'http://www.example.co.uk:80/path/to/myfile.html?key1=value1&key2=value2#SomewhereInTheDocument';
async function extract(url) {
console.log(await extractDomain(url, { tld: true }));
// example.co.uk
}
// Or
extractDomain(url, { tld: true }).then(console.log);
// example.co.uk
Please note that using the tld flag may significantly slow down the process. Benchmark (old) results:
# extract domain 10,000 times
end ~14 ms (0 s + 13572914 ns)
# extract domain with tld 10,000 times
end ~4.29 s (4 s + 288108681 ns)
