Normalize a URL

Package Exports

  • @ohmree/normalize-url
  • @ohmree/normalize-url/index.cjs
  • @ohmree/normalize-url/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@ohmree/normalize-url) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

normalize-url Coverage Status

Normalize a URL

Useful when you need to display, store, deduplicate, sort, compare, etc, URLs.

Note: This package does not do URL sanitization. Garbage in, garbage out. If you use this in a server context and accept URLs as user input, it's up to you to protect against invalid URLs, path traversal attacks, etc.

Install

npm install normalize-url

If you need Safari support, use version 4: npm i normalize-url@4

Usage

import normalizeUrl from 'normalize-url';

normalizeUrl('sindresorhus.com');
//=> 'http://sindresorhus.com'

normalizeUrl('//www.sindresorhus.com:80/../baz?b=bar&a=foo');
//=> 'http://sindresorhus.com/baz?a=foo&b=bar'
