-# node-querystring
+# qs
 
-  query string parser for node and the browser supporting nesting, as it was removed from `0.3.x`, so this library provides the previous and commonly desired behaviour (and twice as fast). Used by [express](http://expressjs.com), [connect](http://senchalabs.github.com/connect) and others.
+A querystring parsing and stringifying library with some added security.
 
-## Installation
+[![Build Status](https://secure.travis-ci.org/hapijs/qs.svg)](http://travis-ci.org/hapijs/qs)
 
-    $ npm install qs
+Lead Maintainer: [Nathan LaFreniere](https://github.com/nlf)
 
-## Examples
+The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
 
-```js
-var qs = require('qs');
+## Usage
 
-qs.parse('user[name][first]=Tobi&user[email]=tobi@learnboost.com');
-// => { user: { name: { first: 'Tobi' }, email: 'tobi@learnboost.com' } }
+```javascript
+var Qs = require('qs');
 
-qs.stringify({ user: { name: 'Tobi', email: 'tobi@learnboost.com' }})
-// => user[name]=Tobi&user[email]=tobi%40learnboost.com
+var obj = Qs.parse('a=c');    // { a: 'c' }
+var str = Qs.stringify(obj);  // 'a=c'
 ```
 
-## Testing
+### Parsing Objects
 
-Install dev dependencies:
+```javascript
+Qs.parse(string, [depth], [delimiter]);
+```
 
-    $ npm install -d
+**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
+For example, the string `'foo[bar]=baz'` converts to:
 
-and execute:
+```javascript
+{
+  foo: {
+    bar: 'baz'
+  }
+}
+```
 
-    $ make test
+URI encoded strings work too:
 
-browser:
+```javascript
+Qs.parse('a%5Bb%5D=c');
+// { a: { b: 'c' } }
+```
 
-    $ open test/browser/index.html
+You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
 
-## License 
+```javascript
+{
+  foo: {
+    bar: {
+      baz: 'foobarbaz'
+    }
+  }
+}
+```
 
-(The MIT License)
+By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
+`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
+
+```javascript
+{
+  a: {
+    b: {
+      c: {
+        d: {
+          e: {
+            f: {
+              '[g][h][i]': 'j'
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+This depth can be overridden by passing a `depth` option to `Qs.parse(string, depth)`:

+```javascript
+Qs.parse('a[b][c][d][e][f][g][h][i]=j', 1);
+// { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }
+```

-permit persons to whom the Software is furnished to do so, subject to
-the following conditions:
+The depth limit mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
 
-The above copyright notice and this permission notice shall be
-included in all copies or substantial portions of the Software.
+An optional delimiter can also be passed:
+
+```javascript
+Qs.parse('a=b;c=d', ';');
+// { a: 'b', c: 'd' }
+```
+
+### Parsing Arrays
+
+**qs** can also parse arrays using a similar `[]` notation:
+
+```javascript
+Qs.parse('a[]=b&a[]=c');
+// { a: ['b', 'c'] }
+```
+
+You may specify an index as well:
+
+```javascript
+Qs.parse('a[1]=c&a[0]=b');
+// { a: ['b', 'c'] }
+```
+
+Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
+to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
+their order:
+
+```javascript
+Qs.parse('a[1]=b&a[15]=c');
+// { a: ['b', 'c'] }
+```
+
+Note that an empty string is also a value, and will be preserved:
+
+```javascript
+Qs.parse('a[]=&a[]=b');
+// { a: ['', 'b'] }
+Qs.parse('a[0]=b&a[1]=&a[2]=c');
+// { a: ['b', '', 'c'] }
+```
+
+**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
+instead be converted to an object with the index as the key:
+
+```javascript
+Qs.parse('a[100]=b');
+// { a: { '100': 'b' } }
+```

-\ No newline at end of file
+If you mix notations, **qs** will merge the two items into an object:
+
+```javascript
+Qs.parse('a[0]=b&a[b]=c');
+// { a: { '0': 'b', b: 'c' } }
+```
+
+You can also create arrays of objects:
+
+```javascript
+Qs.parse('a[][b]=c');
+// { a: [{ b: 'c' }] }
+```
+
+### Stringifying
+
+```javascript
+Qs.stringify(object, [delimiter]);
+```
+
+When stringifying, **qs** always URI encodes output. Objects are stringified as you would expect:
+
+```javascript
+Qs.stringify({ a: 'b' });
+// 'a=b'
+Qs.stringify({ a: { b: 'c' } });
+// 'a%5Bb%5D=c'
+```
+
+Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
+
+When arrays are stringified, they are always given explicit indices:
+
+```javascript
+Qs.stringify({ a: ['b', 'c', 'd'] });
+// 'a[0]=b&a[1]=c&a[2]=d'
+```
+
+Empty strings and null values will omit the value, but the equals sign (=) remains in place:
+
+```javascript
+Qs.stringify({ a: '' });
+// 'a='
+```
+
+Properties that are set to `undefined` will be omitted entirely:
+
+```javascript
+Qs.stringify({ a: null, b: undefined });
+// 'a='
+```
+
+The delimiter may be overridden with stringify as well:
+
+```javascript
+Qs.stringify({ a: 'b', c: 'd' }, ';');
+// 'a=b;c=d'
+```
