Uri parsing and manipulation for node.js and the browser.

var uri = new Uri('http://user:pass@www.test.com:81/index.html?q=books#fragment')

Use property methods to get at the various parts

uri.protocol()    // http
uri.userInfo()    // user:pass
uri.host()        // www.test.com
uri.port()        // 81
uri.path()        // /index.html
uri.query()       // q=books
uri.anchor()      // fragment

Property methods accept an optional value to set

uri.toString()    // https://user:pass@www.test.com:81/index.html?q=books#fragment

uri.toString()    // https://user:pass@www.mydomain.com:81/index.html?q=books#fragment

Chainable setter methods help you compose strings

new Uri()
    .setQuery('?page=1')                   // /archives/1979?page=1

new Uri()
    .setQuery('this=that&some=thing')      // https://username:password@www.test.com:8080/index.html?this=that&some=thing#content

new Uri('http://www.test.com')
    .setProtocol('https')                  // https://www.yahoo.com

Query param methods

Returns the first query param value for the key

new Uri('?cat=1&cat=2&cat=3').getQueryParamValue('cat')             // 1

Returns all query param values for the given key

new Uri('?cat=1&cat=2&cat=3').getQueryParamValues('cat')            // [1, 2, 3]

Internally, query key/value pairs are stored as a series of two-value arrays in the Query object

new Uri('?a=b&c=d').query().params                  // [ ['a', 'b'], ['c', 'd']]

Add query param values

new Uri().addQueryParam('q', 'books')               // ?q=books

new Uri('http://www.github.com')
    .addQueryParam('testing', '123')
    .addQueryParam('one', 1)                        // http://www.github.com/?testing=123&one=1

// insert param at index 0
new Uri('?b=2&c=3&d=4').addQueryParam('a', '1', 0)  // ?a=1&b=2&c=3&d=4

Replace every query string parameter named key with newVal

new Uri().replaceQueryParam('page', 2)     // ?page=2

new Uri('?a=1&b=2&c=3')
    .replaceQueryParam('a', 'eh')          // ?a=eh&b=2&c=3

new Uri('?a=1&b=2&c=3&c=4&c=5&c=6')
    .replaceQueryParam('c', 'five', '5')   // ?a=1&b=2&c=3&c=4&c=five&c=6

Removes instances of query parameters named key

new Uri('?a=1&b=2&c=3')
    .deleteQueryParam('a')                 // ?b=2&c=3

new Uri('test.com?a=1&b=2&c=3&a=eh')
    .deleteQueryParam('a', 'eh')           // test.com/?a=1&b=2&c=3

Create an identical uri object with no shared state

var baseUri = new Uri('http://localhost/')

    baseUri.clone().setProtocol('https')   // https://localhost/
    baseUri                                // http://localhost/

This project incorporates the parseUri regular expression by Steven Levithan.
