JavaScript - Get Portion of URL Path

There is a useful Web API method called URL

const url = new URL('https://www.somedomain.com/account/search?filter=a#top');
console.log(url.pathname.split('/').slice(1)); // drop the leading slash
const params = new URLSearchParams(url.search)
console.log("filter:",params.get("filter"))

If you have an abstract URL string (not from the current window.location), you can use this trick:

let yourUrlString = "http://example.com:3000/pathname/?search=test#hash";

let parser = document.createElement('a');
parser.href = yourUrlString;

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

In case you want to get parts of an URL that you have stored in a variable, I can recommend URL-Parse

const Url = require('url-parse');
const url = new Url('https://github.com/foo/bar');

According to the documentation, it extracts the following parts:

The returned url instance contains the following properties:

protocol: The protocol scheme of the URL (e.g. http:). slashes: A boolean which indicates whether the protocol is followed by two forward slashes (//). auth: Authentication information portion (e.g. username:password). username: Username of basic authentication. password: Password of basic authentication. host: Host name with port number. hostname: Host name without port number. port: Optional port number. pathname: URL path. query: Parsed object containing query string, unless parsing is set to false. hash: The "fragment" portion of the URL including the pound-sign (#). href: The full URL. origin: The origin of the URL.
