+## Install
+
+```
+$ npm install query-string
+```
+
+**Not `npm install querystring`!!!!!**
+
+This module targets Node.js 6 or later and the latest version of Chrome, Firefox, and Safari.
+
+## 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`.
+
+#### options
+
+Type: `object`
+
+##### decode
+
+Type: `boolean`\
+Default: `true`
+
+Decode the keys and values. URL components are decoded with [`decode-uri-component`](https://github.com/SamVerschueren/decode-uri-component).
+
+##### arrayFormat
+
+Type: `string`\
+Default: `'none'`
+
+- `'bracket'`: Parse arrays with bracket representation:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo[]=1&foo[]=2&foo[]=3', {arrayFormat: 'bracket'});
+//=> {foo: ['1', '2', '3']}
+```
+
+- `'index'`: Parse arrays with index representation:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo[0]=1&foo[1]=2&foo[3]=3', {arrayFormat: 'index'});
+//=> {foo: ['1', '2', '3']}
+```
+
+- `'comma'`: Parse arrays with elements separated by comma:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo=1,2,3', {arrayFormat: 'comma'});
+//=> {foo: ['1', '2', '3']}
+```
+
+- `'separator'`: Parse arrays with elements separated by a custom character:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo=1|2|3', {arrayFormat: 'separator', arrayFormatSeparator: '|'});
+//=> {foo: ['1', '2', '3']}
+```
+
+- `'bracket-separator'`: Parse arrays (that are explicitly marked with brackets) with elements separated by a custom character:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo[]', {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> {foo: []}
+
+queryString.parse('foo[]=', {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> {foo: ['']}
+
+queryString.parse('foo[]=1', {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> {foo: ['1']}
+
+queryString.parse('foo[]=1|2|3', {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> {foo: ['1', '2', '3']}
+
+queryString.parse('foo[]=1||3|||6', {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> {foo: ['1', '', 3, '', '', '6']}
+
+queryString.parse('foo[]=1|2|3&bar=fluffy&baz[]=4', {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> {foo: ['1', '2', '3'], bar: 'fluffy', baz:['4']}
+```
+
+- `'colon-list-separator'`: Parse arrays with parameter names that are explicitly marked with `:list`:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo:list=one&foo:list=two', {arrayFormat: 'colon-list-separator'});
+//=> {foo: ['one', 'two']}
+```
+
+- `'none'`: Parse arrays with elements using duplicate keys:
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo=1&foo=2&foo=3');
+//=> {foo: ['1', '2', '3']}
+```
+
+##### arrayFormatSeparator
+
+Type: `string`\
+Default: `','`
+
+The character used to separate array elements when using `{arrayFormat: 'separator'}`.
+
+##### sort
+
+Type: `Function | boolean`\
+Default: `true`
+
+Supports both `Function` as a custom sorting function or `false` to disable sorting.
+
+##### parseNumbers
+
+Type: `boolean`\
+Default: `false`
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo=1', {parseNumbers: true});
+//=> {foo: 1}
+```
+
+Parse the value as a number type instead of string type if it's a number.
+
+##### parseBooleans
+
+Type: `boolean`\
+Default: `false`
+
+```js
+const queryString = require('query-string');
+
+queryString.parse('foo=true', {parseBooleans: true});
+//=> {foo: true}
+```
+
+Parse the value as a boolean type instead of string type if it's a boolean.
+
+### .stringify(object, options?)
+
+Stringify an object into a query string and sorting the keys.
+
+#### options
+
+Type: `object`
+
+##### strict
+
+Type: `boolean`\
+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`\
+Default: `true`
+
+[URL encode](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent) the keys and values.
+
+##### arrayFormat
+
+Type: `string`\
+Default: `'none'`
+
+- `'bracket'`: Serialize arrays using bracket representation:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'bracket'});
+//=> 'foo[]=1&foo[]=2&foo[]=3'
+```
+
+- `'index'`: Serialize arrays using index representation:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'index'});
+//=> 'foo[0]=1&foo[1]=2&foo[2]=3'
+```
+
+- `'comma'`: Serialize arrays by separating elements with comma:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'comma'});
+//=> 'foo=1,2,3'
+
+queryString.stringify({foo: [1, null, '']}, {arrayFormat: 'comma'});
+//=> 'foo=1,,'
+// Note that typing information for null values is lost
+// and `.parse('foo=1,,')` would return `{foo: [1, '', '']}`.
+```
+
+- `'separator'`: Serialize arrays by separating elements with a custom character:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'separator', arrayFormatSeparator: '|'});
+//=> 'foo=1|2|3'
+```
+
+- `'bracket-separator'`: Serialize arrays by explicitly post-fixing array names with brackets and separating elements with a custom character:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: []}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> 'foo[]'
+
+queryString.stringify({foo: ['']}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> 'foo[]='
+
+queryString.stringify({foo: [1]}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> 'foo[]=1'
+
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> 'foo[]=1|2|3'
+
+queryString.stringify({foo: [1, '', 3, null, null, 6]}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> 'foo[]=1||3|||6'
+
+queryString.stringify({foo: [1, '', 3, null, null, 6]}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|', skipNull: true});
+//=> 'foo[]=1||3|6'
+
+queryString.stringify({foo: [1, 2, 3], bar: 'fluffy', baz: [4]}, {arrayFormat: 'bracket-separator', arrayFormatSeparator: '|'});
+//=> 'foo[]=1|2|3&bar=fluffy&baz[]=4'
+```
+
+- `'colon-list-separator'`: Serialize arrays with parameter names that are explicitly marked with `:list`:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: ['one', 'two']}, {arrayFormat: 'colon-list-separator'});
+//=> 'foo:list=one&foo:list=two'
+```
+
+- `'none'`: Serialize arrays by using duplicate keys:
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({foo: [1, 2, 3]});
+//=> 'foo=1&foo=2&foo=3'
+```
+
+##### arrayFormatSeparator
+
+Type: `string`\
+Default: `','`
+
+The character used to separate array elements when using `{arrayFormat: 'separator'}`.
+
+##### sort
+
+Type: `Function | boolean`
+
+Supports both `Function` as a custom sorting function or `false` to disable sorting.
+
+```js
+const queryString = require('query-string');
+
+const order = ['c', 'a', 'b'];
+
+queryString.stringify({a: 1, b: 2, c: 3}, {
+	sort: (a, b) => order.indexOf(a) - order.indexOf(b)
+});
+//=> 'c=3&a=1&b=2'
+```
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({b: 1, c: 2, a: 3}, {sort: false});
+//=> 'b=1&c=2&a=3'
+```
+
+If omitted, keys are sorted using `Array#sort()`, which means, converting them to strings and comparing strings in Unicode code point order.
+
+##### skipNull
+
+Skip keys with `null` as the value.
+
+Note that keys with `undefined` as the value are always skipped.
+
+Type: `boolean`\
+Default: `false`
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({a: 1, b: undefined, c: null, d: 4}, {
+	skipNull: true
+});
+//=> 'a=1&d=4'
+```
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({a: undefined, b: null}, {
+	skipNull: true
+});
+//=> ''
+```
+
+##### skipEmptyString
+
+Skip keys with an empty string as the value.
+
+Type: `boolean`\
+Default: `false`
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({a: 1, b: '', c: '', d: 4}, {
+	skipEmptyString: true
+});
+//=> 'a=1&d=4'
+```
+
+```js
+const queryString = require('query-string');
+
+queryString.stringify({a: '', b: ''}, {
+	skipEmptyString: true
+});
+//=> ''
+```
+
+### .extract(string)
+
+Extract a query string from a URL that can be passed into `.parse()`.
+
+Note: This behaviour can be changed with the `skipNull` option.
+
+### .parseUrl(string, options?)
+
+Extract the URL and the query string as an object.
+
+Returns an object with a `url` and `query` property.
+
+If the `parseFragmentIdentifier` option is `true`, the object will also contain a `fragmentIdentifier` property.
+
+```js
+const queryString = require('query-string');
+
+queryString.parseUrl('https://foo.bar?foo=bar');
+//=> {url: 'https://foo.bar', query: {foo: 'bar'}}
+
+queryString.parseUrl('https://foo.bar?foo=bar#xyz', {parseFragmentIdentifier: true});
+//=> {url: 'https://foo.bar', query: {foo: 'bar'}, fragmentIdentifier: 'xyz'}
+```
+
+#### options
+
+Type: `object`
+
+The options are the same as for `.parse()`.
+
+Extra options are as below.
+
+##### parseFragmentIdentifier
+
+Parse the fragment identifier from the URL.
+
+Type: `boolean`\
+Default: `false`
+
+```js
+const queryString = require('query-string');
+
+queryString.parseUrl('https://foo.bar?foo=bar#xyz', {parseFragmentIdentifier: true});
+//=> {url: 'https://foo.bar', query: {foo: 'bar'}, fragmentIdentifier: 'xyz'}
+```
+
+### .stringifyUrl(object, options?)
+
+Stringify an object into a URL with a query string and sorting the keys. The inverse of [`.parseUrl()`](https://github.com/sindresorhus/query-string#parseurlstring-options)
+
+The `options` are the same as for `.stringify()`.
+
+Returns a string with the URL and a query string.
+
+Query items in the `query` property overrides queries in the `url` property.
+
+The `fragmentIdentifier` property overrides the fragment identifier in the `url` property.
+
+```js
+queryString.stringifyUrl({url: 'https://foo.bar', query: {foo: 'bar'}});
+//=> 'https://foo.bar?foo=bar'
+
+queryString.stringifyUrl({url: 'https://foo.bar?foo=baz', query: {foo: 'bar'}});
+//=> 'https://foo.bar?foo=bar'
+
+queryString.stringifyUrl({
+	url: 'https://foo.bar',
+	query: {
+		top: 'foo'
+	},
+	fragmentIdentifier: 'bar'
+});
+//=> 'https://foo.bar?top=foo#bar'
+```
+
+#### object
+
+Type: `object`
+
+##### url
+
+Type: `string`
+
+The URL to stringify.
+
+##### query
+
+Type: `object`
+
+Query items to add to the URL.
+
+### .pick(url, keys, options?)
+### .pick(url, filter, options?)
+
+Pick query parameters from a URL.
+
+Returns a string with the new URL.
+
+```js
+const queryString = require('query-string');
+
+queryString.pick('https://foo.bar?foo=1&bar=2#hello', ['foo']);
+//=> 'https://foo.bar?foo=1#hello'
+
+queryString.pick('https://foo.bar?foo=1&bar=2#hello', (name, value) => value === 2, {parseNumbers: true});
+//=> 'https://foo.bar?bar=2#hello'
+```
+
+### .exclude(url, keys, options?)
+### .exclude(url, filter, options?)
+
+Exclude query parameters from a URL.
+
+Returns a string with the new URL.
+
+```js
+const queryString = require('query-string');
+
+queryString.exclude('https://foo.bar?foo=1&bar=2#hello', ['foo']);
+//=> 'https://foo.bar?bar=2#hello'
+
+queryString.exclude('https://foo.bar?foo=1&bar=2#hello', (name, value) => value === 2, {parseNumbers: true});
+//=> 'https://foo.bar?foo=1#hello'
+```
+
+#### url
+
+Type: `string`
+
+The URL containing the query parameters to filter.
+
+#### keys
+
+Type: `string[]`
+
+The names of the query parameters to filter based on the function used.
+
+#### filter
+
+Type: `(key, value) => boolean`
+
+A filter predicate that will be provided the name of each query parameter and its value. The `parseNumbers` and `parseBooleans` options also affect `value`.
+
+#### options
+
+Type: `object`
+
+[Parse options](#options) and [stringify options](#options-1).
+
+## 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
+const queryString = require('query-string');
+
+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
+const queryString = require('query-string');
+
+queryString.parse('likes=cake&name=bob&likes=icecream');
+//=> {likes: ['cake', 'icecream'], name: 'bob'}
+
+queryString.stringify({color: ['taupe', 'chartreuse'], id: '515'});
+//=> 'color=taupe&color=chartreuse&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
+const queryString = require('query-string');
+
+queryString.stringify({foo: false});
+//=> 'foo=false'
+
+queryString.stringify({foo: null});
+//=> 'foo'
+
+queryString.stringify({foo: undefined});
+//=> ''
+```
+
+## FAQ
+
+### Why is it parsing `+` as a space?
