parse-url

What is parse-url?

The parse-url npm package is used to parse URLs and extract components such as protocol, auth, host, pathname, query parameters, and hash. It provides a simple API to break down a URL string into its constituent parts for easy access and manipulation.

What are parse-url's main functionalities?

Parsing the URL

This feature allows you to parse a full URL and returns an object with properties like protocol, resource, user, pathname, hash, search, and query. Each property represents a specific part of the URL.

const parseUrl = require('parse-url');
const parsed = parseUrl('https://www.example.com:8080/path/name?query=value#hash');
console.log(parsed);

Parsing the Query String

This feature specifically focuses on parsing the query string part of the URL and converting it into an object for easy access to each query parameter.

const parseUrl = require('parse-url');
const parsed = parseUrl('https://www.example.com/path/name?query=value&another=thing');
console.log(parsed.query);

Reconstructing the URL

After parsing a URL and potentially modifying its components, this feature allows you to reconstruct the URL back into a string.

const parseUrl = require('parse-url');
const parsed = parseUrl('https://www.example.com/path/name');
parsed.resource = 'www.another-example.com';
const reconstructedUrl = parseUrl.stringify(parsed);
console.log(reconstructedUrl);

Other packages similar to parse-url

url-parse

The url-parse package offers similar functionality to parse-url, allowing for the parsing of URLs into components. It also provides the ability to resolve relative URLs against an absolute base URL, which is a feature not present in parse-url.

qs

While qs is not a direct alternative to parse-url, it provides robust query string parsing and stringifying capabilities. It can be used in conjunction with other URL parsing libraries to handle the query string part of URLs more extensively than parse-url.

urijs

URI.js is a URL manipulation library that provides a fluent API for building, parsing, and manipulating URLs. It offers more features than parse-url, such as URL normalization, resolution of relative paths, and support for punycode and IPv6.
