What are normalize-url's main functionalities?
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'"
