#Introduction

Fast implementation of an url parser for node.js.

#Quick start

    npm install fast-url-parser

```js
var url = require("fast-url-parser");
```

#API

This module has exactly the same API and semantics as the `require("url");`- module that comes with node.

See [Node.JS URL API documentation](http://nodejs.org/docs/latest/api/url.html).

In addition, you may inject a custom query string implementation by setting the `url.queryString` property. The module export object must expose the methods `.parse` and `.stringify`. By default the core `"querystring"` module is used.

You may disable automatic escaping of some characters when parsing an URL by passing `true` as a forth argument so that: `url.format(url.parse(yourUrl, false, false, true)) == yourUrl`

Example:

```js
var url = require("fast-url-parser");
// the querystringparser module supports nested properties
url.queryString = require("querystringparser");
var parsed = Url.parse('/path?user[name][first]=tj&user[name][last]=holowaychuk', true);
console.log(parsed.query);
//{ user: { name: { first: 'tj', last: 'holowaychuk' } } }
```

If in your application you may want all modules use this parser automatically, you can do so by inserting this line at the beginning of your application:

```js
require("fast-url-parser").replace();
```

Anything that now calls `require("url")` will instead get an instance of this module instead of the url parser that comes with node core.
