url-parse

What is url-parse?

The url-parse package is a robust tool for parsing URLs in Node.js and browser environments. It provides a convenient way to break down a URL into its components, such as protocol, host, path, query parameters, and hash. This package is useful for applications that need to manipulate or extract information from URLs.

What are url-parse's main functionalities?

Parsing URL

This feature allows you to parse a full URL into its constituent parts, including protocol, username, password, host, port, pathname, query, and hash. The second parameter set to true parses the query string into an object.

const parse = require('url-parse');
const url = parse('http://username:[e-mail]:8080/p/a/t/h?query=string#hash', true);
console.log(url.protocol); // 'http:'
console.log(url.host); // 'host.com:8080'

Manipulating Query Strings

This feature demonstrates how to manipulate query strings. After parsing the URL with the query string parsing option enabled, you can easily add, modify, or delete query parameters and then serialize the URL back to a string.

const parse = require('url-parse');
const url = parse('http://example.com?foo=bar', true);
url.query.newParam = 'newValue';
console.log(url.toString()); // 'http://example.com/?foo=bar&newParam=newValue'

Relative URL Resolution

This feature shows how to resolve relative URLs against a base URL. By parsing both the base and relative URLs, you can combine their components to form a new, resolved URL.

const parse = require('url-parse');
const baseUrl = parse('http://example.com/directory/');
const relativeUrl = parse('another/directory', true);
const resolvedUrl = baseUrl.set('pathname', baseUrl.pathname + relativeUrl.pathname);
console.log(resolvedUrl.toString()); // 'http://example.com/directory/another/directory'

Other packages similar to url-parse

whatwg-url

This package implements the URL standard as specified by the WHATWG (Web Hypertext Application Technology Working Group). It offers more comprehensive support for the URL standard than url-parse, including features like URLSearchParams. However, it might be more complex to use for simple URL parsing and manipulation tasks.
