#Introduction

Fast implementation of an url parser for node.js.

#Quick start

npm install fast-url-parser

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.

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:

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:

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.
