lite-url

A small cross-browser JS lib for parsing a URL into its component parts.

Broadly provides the same interface as the native URL function, but in a cross browser way (taken from Chrome 35):

new URL('http://user:pass@example.com:8080/directory/file.ext?query=1#anchor'); //results in...

{
  "hash": "#anchor",
  "search": "?query=1",
  "pathname": "/directory/file.ext",
  "port": "8080",
  "hostname": "example.com",
  "host": "example.com:8080",
  "password": "pass",
  "username": "user",
  "protocol": "http:",
  "origin": "http://example.com:8080",
  "href": "http://user:pass@example.com:8080/directory/file.ext?query=1#anchor"
}

install

manual

grab the minified version from dist/

bower

bower install --save lite-url

npm

npm install --save lite-url

(Since node.js already has built-in parsing functionality, this is only really useful if you are using browserify and want to keep the size down).

2 variations from chrome

1. more permissive

The following will parse in this lib but not in chrome (this is intentional):

  1. new URL('//user:pass@example.com:8080/directory/file.ext?query=1#anchor'); //results in empty protocol
  2. new URL('?foo=bar&bingobang=&king=kong@kong.com#foobar/bing/bo@ng?b#ang'); //populates only href, hash, search, params

Both of the above would throw an error in chrome's native URL() parser.

2. query parser

Technically, there shouldn't be a parsed version of the query in the result (since the Chrome URL parser doesn't do this).

If you don't like the behaviour you can change it by calling changeQueryParser with a function. That function will be given the deconstructed url and expects the query params back.

E.g. If you want duplicate keys to be turned into an array, you could do this:

liteURL.changeQueryParser(function (uri) {
    var params = {};

    //strip the question mark from search
    var query = uri.search ? uri.search.substring(uri.search.indexOf('?') + 1) : '';
    query.replace(/(?:^|&)([^&=]*)=?([^&]*)/g, function ($0, $1, $2) {
        //query isn't actually modified, .replace() is used as an iterator to populate params
        if ($1) {
            if (params[$1]) {
                if (params[$1] instanceof Array) {
                    params[$1].push($2);
                } else {
                    params[$1] = [params[$1], $2];
                }
            } else {
                params[$1] = $2;
            }
        }
    });
    return params;
});

(The default behaviour will only ever return a string for a key, and it will be the last string it finds for that key.)

usage

<script src="lite-url.min.js"></script>
<script>
    var url = 'http://user:pass@example.com:8080/directory/file.ext?query=1#anchor';
    var parsed = new liteURL(url);
    console.log(parsed);
</script>

notes

The URL object in Chrome etc doesn't quite fit with other interpretations of the spec (http://en.wikipedia.org/wiki/URI_scheme#Examples).

alternatives

developing

testing

npm install -g gulp
npm install && bower install
gulp

crossbrowser testing with saucelabs

using config file:

cp saucelabs.example.json saucelabs.json

add your saucelabs username/secret key, and run:

npm test

you can do the same on cmdline with:

export SAUCE_USERNAME='your username' && export SAUCE_ACCESS_KEY='your key' && npm test

building

for npm (assuming setup correctly with npm)

npm publish

for bower, just tag correct semver and push to github.
