+# query-string [![Build Status](https://travis-ci.org/sindresorhus/query-string.svg?branch=master)](https://travis-ci.org/sindresorhus/query-string)
+
+> Parse and stringify URL [query strings](http://en.wikipedia.org/wiki/Query_string)
+
+---
+
+<p align="center"><b>🔥 Want to strengthen your core JavaScript skills and master ES6?</b><br>I would personally recommend this awesome <a href="https://ES6.io/friend/AWESOME">ES6 course</a> by Wes Bos. You might also like his <a href="https://ReactForBeginners.com/friend/AWESOME">React course</a>.</p>
+
+---
+
+
+## Install
+
+```
+$ npm install --save query-string
+```
+
+
+## Usage
+
+```js
+const queryString = require('query-string');
+
+console.log(location.search);
+//=> '?foo=bar'
+
+const parsed = queryString.parse(location.search);
+console.log(parsed);
+//=> {foo: 'bar'}
+
+console.log(location.hash);
+//=> '#token=bada55cafe'
+
+const parsedHash = queryString.parse(location.hash);
+console.log(parsedHash);
+//=> {token: 'bada55cafe'}
+
+parsed.foo = 'unicorn';
+parsed.ilike = 'pizza';
+
+const stringified = queryString.stringify(parsed);
+//=> 'foo=unicorn&ilike=pizza'
+
+location.search = stringified;
+// note that `location.search` automatically prepends a question mark
+console.log(location.search);
+//=> '?foo=unicorn&ilike=pizza'
+```
+
+
+## API
+
+### .parse(*string*, *[options]*)
+
+Parse a query string into an object. Leading `?` or `#` are ignored, so you can pass `location.search` or `location.hash` directly.
+
+The returned object is created with [`Object.create(null)`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create) and thus does not have a `prototype`.
+
+#### arrayFormat
+
+Type: `string`<br>
+Default: `'none'`
+
+Supports both `index` for an indexed array representation or `bracket` for a *bracketed* array representation.
+
+- `bracket`: stands for parsing correctly arrays with bracket representation on the query string, such as:
+
+```js
+queryString.parse('foo[]=1&foo[]=2&foo[]=3', {arrayFormat: 'bracket'});
+//=> foo: [1,2,3]
+```
+
+- `index`: stands for parsing taking the index into account, such as:
+
+```js
+queryString.parse('foo[0]=1&foo[1]=2&foo[3]=3', {arrayFormat: 'index'});
+//=> foo: [1,2,3]
+```
+
+- `none`: is the **default** option and removes any bracket representation, such as:
+
+```js
+queryString.parse('foo=1&foo=2&foo=3');
+//=> foo: [1,2,3]
+```
+
+### .stringify(*object*, *[options]*)
+
+Stringify an object into a query string, sorting the keys.
+
+#### strict
+
+Type: `boolean`<br>
+Default: `true`
+
+Strictly encode URI components with [strict-uri-encode](https://github.com/kevva/strict-uri-encode). It uses [encodeURIComponent](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent)
+if set to false. You probably [don't care](https://github.com/sindresorhus/query-string/issues/42) about this option.
+
+#### encode
+
+Type: `boolean`<br>
+Default: `true`
+
+[URL encode](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent) the keys and values.
+
+#### arrayFormat
+
+Type: `string`<br>
+Default: `'none'`
+
+Supports both `index` for an indexed array representation or `bracket` for a *bracketed* array representation.
+
+- `bracket`: stands for parsing correctly arrays with bracket representation on the query string, such as:
+
+```js
+queryString.stringify({foo: [1,2,3]}, {arrayFormat: 'bracket'});
+// => foo[]=1&foo[]=2&foo[]=3
+```
+
+- `index`: stands for parsing taking the index into account, such as:
+
+```js
+queryString.stringify({foo: [1,2,3]}, {arrayFormat: 'index'});
+// => foo[0]=1&foo[1]=2&foo[3]=3
+```
+
+- `none`: is the __default__ option and removes any bracket representation, such as:
+
+```js
+queryString.stringify({foo: [1,2,3]});
+// => foo=1&foo=2&foo=3
+```
+
+### .extract(*string*)
+
+Extract a query string from a URL that can be passed into `.parse()`.
+
+
+## Nesting
+
+This module intentionally doesn't support nesting as it's not spec'd and varies between implementations, which causes a lot of [edge cases](https://github.com/visionmedia/node-querystring/issues).
+
+You're much better off just converting the object to a JSON string:
+
+```js
+queryString.stringify({
+	foo: 'bar',
+	nested: JSON.stringify({
+		unicorn: 'cake'
+	})
+});
+//=> 'foo=bar&nested=%7B%22unicorn%22%3A%22cake%22%7D'
+```
+
+However, there is support for multiple instances of the same key:
+
+```js
+queryString.parse('likes=cake&name=bob&likes=icecream');
+//=> {likes: ['cake', 'icecream'], name: 'bob'}
+
+queryString.stringify({color: ['taupe', 'chartreuse'], id: '515'});
+//=> 'color=chartreuse&color=taupe&id=515'
+```
+
+
+## Falsy values
+
+Sometimes you want to unset a key, or maybe just make it present without assigning a value to it. Here is how falsy values are stringified:
+
+```js
+queryString.stringify({foo: false});
+//=> 'foo=false'
+
+queryString.stringify({foo: null});
+//=> 'foo'
+
+queryString.stringify({foo: undefined});
+//=> ''
+```
