`TLD support
library.Examples
`bash
npm i --save-optional psl
`js
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)
