normalize-url
Advanced tools
The normalize-url npm package is used to normalize and sanitize URLs to ensure they have a standard and consistent format. It can be used to remove tracking parameters, sort query parameters, remove default ports, and more.
Normalizing URLs
This feature allows you to normalize a URL by converting it to a standard format. It can remove or add 'http://', sort query parameters, and convert the hostname to lowercase.
"use strict";
const normalizeUrl = require('normalize-url');
console.log(normalizeUrl('sindresorhus.com')); // Output: 'http://sindresorhus.com'
console.log(normalizeUrl('HTTP://xn--xample-hva.com:80/?b=bar&a=foo')); // Output: 'http://êxample.com/?a=foo&b=bar'"
Removing URL Tracking Parameters
This feature allows you to remove URL tracking parameters like 'utm_source' and 'utm_medium' by using a regular expression.
"use strict";
const normalizeUrl = require('normalize-url');
console.log(normalizeUrl('www.sindresorhus.com?utm_source=foo&utm_medium=bar', {removeQueryParameters: [/^utm_/]})); // Output: 'http://sindresorhus.com'"
Removing Default Ports
This feature removes the default ports from URLs (port 80 for HTTP and port 443 for HTTPS).
"use strict";
const normalizeUrl = require('normalize-url');
console.log(normalizeUrl('http://sindresorhus.com:80')); // Output: 'http://sindresorhus.com'
console.log(normalizeUrl('https://sindresorhus.com:443')); // Output: 'https://sindresorhus.com'"
Forcing HTTPS
This feature allows you to force the URL to use HTTPS instead of HTTP.
"use strict";
const normalizeUrl = require('normalize-url');
console.log(normalizeUrl('http://sindresorhus.com', {forceHttps: true})); // Output: 'https://sindresorhus.com'"
The url-parse package offers similar URL parsing and normalization functionalities. It provides a more detailed breakdown of URL components and allows manipulation of these components individually.
URI.js is a library for working with URLs. It includes URL manipulation and normalization features, but also offers more extensive options for working with URIs, such as resolving URIs, managing URI components, and building URIs from templates.
