+
+A querystring parsing and stringifying library with some added security.
+
+Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
+
+The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
+
+## Usage
+
+```javascript
+var qs = require('qs');
+var assert = require('assert');
+
+var obj = qs.parse('a=c');
+assert.deepEqual(obj, { a: 'c' });
+
+var str = qs.stringify(obj);
+assert.equal(str, 'a=c');
+```
+
+### Parsing Objects
+
+[](#preventEval)
+```javascript
+qs.parse(string, [options]);
+```
+
+**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:
+
+```javascript
+assert.deepEqual(qs.parse('foo[bar]=baz'), {
+    foo: {
+        bar: 'baz'
+    }
+});
+```
+
+When using the `plainObjects` option the parsed value is returned as a null object, created via `Object.create(null)` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
+
+```javascript
+var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
+assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
+```
+
+By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties. *WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten. Always be careful with this option.
+
+```javascript
+var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
+assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
+```
+
+URI encoded strings work too:
+
+```javascript
+assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
+    a: { b: 'c' }
+});
+```
+
+You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
+
+```javascript
+assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
+    foo: {
+        bar: {
+            baz: 'foobarbaz'
+        }
+    }
+});
+```
+
+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
+var expected = {
+    a: {
+        b: {
+            c: {
+                d: {
+                    e: {
+                        f: {
+                            '[g][h][i]': 'j'
+                        }
+                    }
+                }
+            }
+        }
+    }
+};
+var string = 'a[b][c][d][e][f][g][h][i]=j';
+assert.deepEqual(qs.parse(string), expected);
+```
+
+This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
+
+```javascript
+var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
+assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
+```
+
+The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
+
+For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
+
+```javascript
+var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
+assert.deepEqual(limited, { a: 'b' });
+```
+
+To bypass the leading question mark, use `ignoreQueryPrefix`:
+
+```javascript
+var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
+assert.deepEqual(prefixed, { a: 'b', c: 'd' });
+```
+
+An optional delimiter can also be passed:
+
+```javascript
+var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
+assert.deepEqual(delimited, { a: 'b', c: 'd' });
+```
+
+Delimiters can be a regular expression too:
+
+```javascript
+var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
+assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
+```
+
+Option `allowDots` can be used to enable dot notation:
+
+```javascript
+var withDots = qs.parse('a.b=c', { allowDots: true });
+assert.deepEqual(withDots, { a: { b: 'c' } });
+```
+
+### Parsing Arrays
+
+**qs** can also parse arrays using a similar `[]` notation:
+
+```javascript
+var withArray = qs.parse('a[]=b&a[]=c');
+assert.deepEqual(withArray, { a: ['b', 'c'] });
+```
+
+You may specify an index as well:
+
+```javascript
+var withIndexes = qs.parse('a[1]=c&a[0]=b');
+assert.deepEqual(withIndexes, { 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
+var noSparse = qs.parse('a[1]=b&a[15]=c');
+assert.deepEqual(noSparse, { a: ['b', 'c'] });
+```
+
+Note that an empty string is also a value, and will be preserved:
+
+```javascript
+var withEmptyString = qs.parse('a[]=&a[]=b');
+assert.deepEqual(withEmptyString, { a: ['', 'b'] });
+
+var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
+assert.deepEqual(withIndexedEmptyString, { 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
+var withMaxIndex = qs.parse('a[100]=b');
+assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
+```
+
+This limit can be overridden by passing an `arrayLimit` option:
+
+```javascript
+var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
+assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
+```
+
+To disable array parsing entirely, set `parseArrays` to `false`.
+
+```javascript
+var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
+assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
+```
+
+If you mix notations, **qs** will merge the two items into an object:
+
+```javascript
+var mixedNotation = qs.parse('a[0]=b&a[b]=c');
+assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
+```
+
+You can also create arrays of objects:
+
+```javascript
+var arraysOfObjects = qs.parse('a[][b]=c');
+assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
+```
+
+### Stringifying
+
+[](#preventEval)
+```javascript
+qs.stringify(object, [options]);
+```
+
+When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b' }), 'a=b');
+assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
+```
+
+This encoding can be disabled by setting the `encode` option to `false`:
+
+```javascript
+var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
+assert.equal(unencoded, 'a[b]=c');
+```
+
+Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
+```javascript
+var encodedValues = qs.stringify(
+    { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
+    { encodeValuesOnly: true }
+);
+assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
+```
+
+This encoding can also be replaced by a custom encoding method set as `encoder` option:
+
+```javascript
+var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
+    // Passed in values `a`, `b`, `c`
+    return // Return encoded string
+}})
+```
+
+_(Note: the `encoder` option does not apply if `encode` is `false`)_
+
+Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
+
+```javascript
+var decoded = qs.parse('x=z', { decoder: function (str) {
+    // Passed in values `x`, `z`
+    return // Return decoded string
+}})
+```
+
+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, by default they are given explicit indices:
+
+```javascript
+qs.stringify({ a: ['b', 'c', 'd'] });
+// 'a[0]=b&a[1]=c&a[2]=d'
+```
+
+You may override this by setting the `indices` option to `false`:
+
+```javascript
+qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
+// 'a=b&a=c&a=d'
+```
+
+You may use the `arrayFormat` option to specify the format of the output array:
+
+```javascript
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
+// 'a[0]=b&a[1]=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
+// 'a[]=b&a[]=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
+// 'a=b&a=c'
+```
+
+When objects are stringified, by default they use bracket notation:
+
+```javascript
+qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
+// 'a[b][c]=d&a[b][e]=f'
+```
+
+You may override this to use dot notation by setting the `allowDots` option to `true`:
+
+```javascript
+qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
+// 'a.b.c=d&a.b.e=f'
+```
+
+Empty strings and null values will omit the value, but the equals sign (=) remains in place:
+
+```javascript
+assert.equal(qs.stringify({ a: '' }), 'a=');
+```
+
+Key with no values (such as an empty object or array) will return nothing:
+
+```javascript
+assert.equal(qs.stringify({ a: [] }), '');
+assert.equal(qs.stringify({ a: {} }), '');
+assert.equal(qs.stringify({ a: [{}] }), '');
+assert.equal(qs.stringify({ a: { b: []} }), '');
+assert.equal(qs.stringify({ a: { b: {}} }), '');
+```
+
+Properties that are set to `undefined` will be omitted entirely:
+
+```javascript
+assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
+```
+
+The query string may optionally be prepended with a question mark:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
+```
+
+The delimiter may be overridden with stringify as well:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
+```
+
+If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
+
+```javascript
+var date = new Date(7);
+assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
+assert.equal(
+    qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
+    'a=7'
+);
+```
+
+You may use the `sort` option to affect the order of parameter keys:
+
+```javascript
+function alphabeticalSort(a, b) {
+    return a.localeCompare(b);
+}
+assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
+```
+
+Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
+If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you
+pass an array, it will be used to select properties and array indices for stringification:
+
+```javascript
+function filterFunc(prefix, value) {
+    if (prefix == 'b') {
+        // Return an `undefined` value to omit a property.
+        return;
+    }
+    if (prefix == 'e[f]') {
+        return value.getTime();
+    }
+    if (prefix == 'e[g][0]') {
+        return value * 2;
+    }
+    return value;
+}
+qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
+// 'a=b&c=d&e[f]=123&e[g][0]=4'
+qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
+// 'a=b&e=f'
+qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
+// 'a[0]=b&a[2]=d'
+```
+
+### Handling of `null` values
+
+By default, `null` values are treated like empty strings:
+
+```javascript
+var withNull = qs.stringify({ a: null, b: '' });
+assert.equal(withNull, 'a=&b=');
+```
+
+Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings.
+
+```javascript
+var equalsInsensitive = qs.parse('a&b=');
+assert.deepEqual(equalsInsensitive, { a: '', b: '' });
+```
+
+To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
+values have no `=` sign:
+
+```javascript
+var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
+assert.equal(strictNull, 'a&b=');
+```
+
+To parse values without `=` back to `null` use the `strictNullHandling` flag:
+
+```javascript
+var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
+assert.deepEqual(parsedStrictNull, { a: null, b: '' });
+```
+
+To completely skip rendering keys with `null` values, use the `skipNulls` flag:
+
+```javascript
+var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
+assert.equal(nullsSkipped, 'a=b');
+```
+
+### Dealing with special character sets
+
+By default the encoding and decoding of characters is done in `utf-8`. If you
+wish to encode querystrings to a different character set (i.e.
+[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
+[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
+
+```javascript
+var encoder = require('qs-iconv/encoder')('shift_jis');
+var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
+assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
+```
+
+This also works for decoding of query strings:
+
+```javascript
+var decoder = require('qs-iconv/decoder')('shift_jis');
+var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
+assert.deepEqual(obj, { a: 'こんにちは！' });
+```
+
+### RFC 3986 and RFC 1738 space encoding
+
+RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
+In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
+
+```
+assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c');
+assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c');
+assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
+```
