A very small, fast, dependency free url parser and formatter for nodejs and the web

• fast
• few lines of code
• 100% test coverage

why is it so small and fast?

It extracts all url fragments in a single step using one massive regex

usage

npm install --save urlite

var url = require('urlite')

url.parse('http://user:pass@blah.com:3000/path?query=string#fragment')

{
  auth: 'user:pass',
  hash: '#fragment',
  hostname: 'blah.com',
  href: 'http://user:pass@blah.com:3000/path?query=string#fragment',
  path: '/path?query=string',
  pathname: '/path',
  port: '3000',
  protocol: 'http:',
  search: '?query=string'
}

var href = window.location.href
url.format(url.parse(href)) === href

Urlite extra

An extended version of urlite is available at urlite/extra. This includes helpful features such as querystring and auth parsing:

// version of urlite with additional extras like querystring and auth parsing
var url = require('urlite/extra')
var parsed = url.parse('http://user:pass@blah.com:3000/path?a=b#fragment')
parsed.search // -> { a: "b" }
parsed.search.a = 'c'
parsed.auth // -> { user: 'user', password: 'password' }
url.format(parsed) // -> 'http://user:pass@blah.com:3000/path?a=c#fragment'
