Node.js body parsing middleware.
Parse incoming request bodies in a middleware before your handlers, available
under the `req.body` property.
**Note** As `req.body`'s shape is based on user-controlled input, all
properties and values in this object are untrusted and should be validated
before trusting. For example, `req.body.foo.toString()` may fail in multiple
ways, for example the `foo` property may not be there or may not be a string,
and `toString` may not be a function and instead a string or other user input.
[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
_This does not handle multipart bodies_, due to their complex and typically
large nature. For multipart bodies, you may be interested in the following
modules:
* [busboy](https://www.npmjs.org/package/busboy#readme) and
[connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
* [multiparty](https://www.npmjs.org/package/multiparty#readme) and
[connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
* [formidable](https://www.npmjs.org/package/formidable#readme)
* [multer](https://www.npmjs.org/package/multer#readme)
This module provides the following parsers:
* [JSON body parser](#bodyparserjsonoptions)
* [Raw body parser](#bodyparserrawoptions)
* [Text body parser](#bodyparsertextoptions)
* [URL-encoded form body parser](#bodyparserurlencodedoptions)
Other body parsers you might be interested in:
- [body](https://www.npmjs.org/package/body#readme)
- [co-body](https://www.npmjs.org/package/co-body#readme)
## Installation
```sh
$ npm install body-parser
```
## API
```js
var bodyParser = require('body-parser')
```
The `bodyParser` object exposes various factories to create middlewares. All
middlewares will populate the `req.body` property with the parsed body when
the `Content-Type` request header matches the `type` option, or an empty
object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
or an error occurred.
The various errors returned by this module are described in the
[errors section](#errors).
### bodyParser.json([options])
Returns middleware that only parses `json` and only looks at requests where
the `Content-Type` header matches the `type` option. This parser accepts any
Unicode encoding of the body and supports automatic inflation of `gzip` and
`deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`).
#### Options
The `json` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### reviver
The `reviver` option is passed directly to `JSON.parse` as the second
argument. You can find more information on this argument
[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
##### strict
When set to `true`, will only accept arrays and objects; when `false` will
accept anything `JSON.parse` accepts. Defaults to `true`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not a
function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `json`), a mime type (like `application/json`), or
a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a truthy
value. Defaults to `application/json`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.raw([options])
Returns middleware that parses all bodies as a `Buffer` and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip` and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a `Buffer` object
of the body.
#### Options
The `raw` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function.
If not a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this
can be an extension name (like `bin`), a mime type (like
`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
`application/*`). If a function, the `type` option is called as `fn(req)`
and the request is parsed if it returns a truthy value. Defaults to
`application/octet-stream`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.text([options])
Returns middleware that parses all bodies as a string and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip` and `deflate` encodings.
A new `body` string containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a string of the
body.
#### Options
The `text` function takes an optional `options` object that may contain any of
the following keys:
##### defaultCharset
Specify the default character set for the text content if the charset is not
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a
truthy value. Defaults to `text/plain`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.urlencoded([options])
Returns middleware that only parses `urlencoded` bodies and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser accepts only UTF-8 encoding of the body and supports automatic
inflation of `gzip` and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This object will contain
key-value pairs, where the value can be a string or array (when `extended` is
`false`), or any type (when `extended` is `true`).
#### Options
The `urlencoded` function takes an optional `options` object that may contain
any of the following keys:
##### extended
The `extended` option allows to choose between parsing the URL-encoded data
with the `querystring` library (when `false`) or the `qs` library (when
`true`). The "extended" syntax allows for rich objects and arrays to be
encoded into the URL-encoded format, allowing for a JSON-like experience
with URL-encoded. For more information, please
[see the qs library](https://www.npmjs.org/package/qs#readme).
Defaults to `true`, but using the default has been deprecated. Please
research into the difference between `qs` and `querystring` and choose the
appropriate setting.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### parameterLimit
The `parameterLimit` option controls the maximum number of parameters that
are allowed in the URL-encoded data. If a request contains more parameters
than this value, a 413 will be returned to the client. Defaults to `1000`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `urlencoded`), a mime type (like
`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
`*/x-www-form-urlencoded`). If a function, the `type` option is called as
`fn(req)` and the request is parsed if it returns a truthy value. Defaults
to `application/x-www-form-urlencoded`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
## Errors
The middlewares provided by this module create errors using the
[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
will typically have a `status`/`statusCode` property that contains the suggested
HTTP response code, an `expose` property to determine if the `message` property
should be displayed to the client, a `type` property to determine the type of
error without matching against the `message`, and a `body` property containing
the read body, if available.
The following are the common errors created, though any error can come through
for various reasons.
### content encoding unsupported
This error will occur when the request had a `Content-Encoding` header that
contained an encoding but the "inflation" option was set to `false`. The
`status` property is set to `415`, the `type` property is set to
`'encoding.unsupported'`, and the `charset` property will be set to the
encoding that is unsupported.
### entity parse failed
This error will occur when the request contained an entity that could not be
parsed by the middleware. The `status` property is set to `400`, the `type`
property is set to `'entity.parse.failed'`, and the `body` property is set to
the entity value that failed parsing.
### entity verify failed
This error will occur when the request contained an entity that could not be
failed verification by the defined `verify` option. The `status` property is
set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
`body` property is set to the entity value that failed verification.
### request aborted
This error will occur when the request is aborted by the client before reading
the body has finished. The `received` property will be set to the number of
bytes received before the request was aborted and the `expected` property is
set to the number of expected bytes. The `status` property is set to `400`
and `type` property is set to `'request.aborted'`.
### request entity too large
This error will occur when the request body's size is larger than the "limit"
option. The `limit` property will be set to the byte limit and the `length`
property will be set to the request body's length. The `status` property is
set to `413` and the `type` property is set to `'entity.too.large'`.
### request size did not match content length
This error will occur when the request's length did not match the length from
the `Content-Length` header. This typically occurs when the request is malformed,
typically when the `Content-Length` header was calculated based on characters
instead of bytes. The `status` property is set to `400` and the `type` property
is set to `'request.size.invalid'`.
### stream encoding should not be set
This error will occur when something called the `req.setEncoding` method prior
to this middleware. This module operates directly on bytes only and you cannot
call `req.setEncoding` when using this module. The `status` property is set to
`500` and the `type` property is set to `'stream.encoding.set'`.
### stream is not readable
This error will occur when the request is no longer readable when this middleware
attempts to read it. This typically means something other than a middleware from
this module read the request body already and the middleware was also configured to
read the same request. The `status` property is set to `500` and the `type`
property is set to `'stream.not.readable'`.
### too many parameters
This error will occur when the content of the request exceeds the configured
`parameterLimit` for the `urlencoded` parser. The `status` property is set to
`413` and the `type` property is set to `'parameters.too.many'`.
### unsupported charset "BOGUS"
This error will occur when the request had a charset parameter in the
`Content-Type` header, but the `iconv-lite` module does not support it OR the
parser does not support it. The charset is contained in the message as well
as in the `charset` property. The `status` property is set to `415`, the
`type` property is set to `'charset.unsupported'`, and the `charset` property
is set to the charset that is unsupported.
### unsupported content encoding "bogus"
This error will occur when the request had a `Content-Encoding` header that
contained an unsupported encoding. The encoding is contained in the message
as well as in the `encoding` property. The `status` property is set to `415`,
the `type` property is set to `'encoding.unsupported'`, and the `encoding`
property is set to the encoding that is unsupported.
## Examples
### Express/Connect top-level generic
This example demonstrates adding a generic JSON and URL-encoded parser as a
top-level middleware, which will parse the bodies of all incoming requests.
This is the simplest setup.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
app.use(function (req, res) {
res.setHeader('Content-Type', 'text/plain')
res.write('you posted:\n')
res.end(JSON.stringify(req.body, null, 2))
})
```
### Express route-specific
This example demonstrates adding body parsers specifically to the routes that
need them. In general, this is the most recommended way to use body-parser with
Express.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// create application/json parser
var jsonParser = bodyParser.json()
// create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })
// POST /login gets urlencoded bodies
app.post('/login', urlencodedParser, function (req, res) {
res.send('welcome, ' + req.body.username)
})
// POST /api/users gets JSON bodies
app.post('/api/users', jsonParser, function (req, res) {
// create user in req.body
})
```
### Change accepted type for parsers
All the parsers accept a `type` option which allows you to change the
`Content-Type` that the middleware will parse.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse various different custom JSON types as JSON
app.use(bodyParser.json({ type: 'application/*+json' }))
// parse some custom thing into a Buffer
app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
// parse an HTML body into a string
app.use(bodyParser.text({ type: 'text/html' }))
```

# Bytes utility
[![NPM Version][npm-image]][npm-url]
[![NPM Downloads][downloads-image]][downloads-url]
[![Build Status][ci-image]][ci-url]
[![Test Coverage][coveralls-image]][coveralls-url]
Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```bash
$ npm install bytes
```
## Usage
```js
var bytes = require('bytes');
```
#### bytes(numberstring value, [options]): numberstringnull
Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number``string` | Number value to format or string value to parse |
| options | `Object` | Conversion options for `format` |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string``number``null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
**Example**
```js
bytes(1024);
// output: '1KB'
bytes('1KB');
// output: 1024
```
#### bytes.format(number value, [options]): stringnull
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
rounded.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number` | Value in bytes |
| options | `Object` | Conversion options |
**Options**
| Property | Type | Description |
|-------------------|--------|-----------------------------------------------------------------------------------------|
| decimalPlaces | `number``null` | Maximum number of decimal places to include in output. Default value to `2`. |
| fixedDecimals | `boolean``null` | Whether to always display the maximum number of decimal places. Default value to `false` |
| thousandsSeparator | `string``null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
| unit | `string``null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
| unitSeparator | `string``null` | Separator to use between number and unit. Default value to `''`. |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string``null` | Return null upon error. String value otherwise. |
**Example**
```js
bytes.format(1024);
// output: '1KB'
bytes.format(1000);
// output: '1000B'
bytes.format(1000, {thousandsSeparator: ' '});
// output: '1 000B'
bytes.format(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'
bytes.format(1024, {unitSeparator: ' '});
// output: '1 KB'
```
#### bytes.parse(stringnumber value): numbernull
Parse the string value into an integer in bytes. If no unit is given, or `value`
is a number, it is assumed the value is in bytes.
Supported units and abbreviations are as follows and are case-insensitive:
* `b` for bytes
* `kb` for kilobytes
* `mb` for megabytes
* `gb` for gigabytes
* `tb` for terabytes
* `pb` for petabytes
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
**Arguments**
| Name | Type | Description |
|---------------|--------|--------------------|
| value | `string``number` | String to parse, or number in bytes. |
**Returns**
| Name | Type | Description |
|---------|-------------|-------------------------|
| results | `number``null` | Return null upon error. Value in bytes otherwise. |
**Example**
```js
bytes.parse('1KB');
// output: 1024
bytes.parse('1024');
// output: 1024
bytes.parse(1024);
// output: 1024

# debug
[![Build Status](https://travis-ci.org/visionmedia/debug.svg?branch=master)](https://travis-ci.org/visionmedia/debug) [![Coverage Status](https://coveralls.io/repos/github/visionmedia/debug/badge.svg?branch=master)](https://coveralls.io/github/visionmedia/debug?branch=master) [![Slack](https://visionmedia-community-slackin.now.sh/badge.svg)](https://visionmedia-community-slackin.now.sh/) [![OpenCollective](https://opencollective.com/debug/backers/badge.svg)](#backers)
[![OpenCollective](https://opencollective.com/debug/sponsors/badge.svg)](#sponsors)
A tiny node.js debugging utility modelled after node core's debugging technique.
**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
## Installation
```bash
$ npm install debug
```
## Usage
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
Example _app.js_:
```js
var debug = require('debug')('http')
, http = require('http')
, name = 'My App';
// fake app
debug('booting %s', name);
http.createServer(function(req, res){
debug(req.method + ' ' + req.url);
res.end('hello\n');
}).listen(3000, function(){
debug('listening');
});
// fake worker of some kind
require('./worker');
```
Example _worker.js_:
```js
var debug = require('debug')('worker');
setInterval(function(){
debug('doing some work');
}, 1000);
```
The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
#### Windows note
On Windows the environment variable is set using the `set` command.
```cmd
set DEBUG=*,-not_this
```
Note that PowerShell uses different syntax to set environment variables.
```cmd
$env:DEBUG = "*,-not_this"
```
Then, run the program to be debugged as usual.
## Millisecond diff
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
## Conventions
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
## Wildcards
The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
## Environment Variables
When running through Node.js, you can set a few environment variables that will
change the behavior of the debug logging:
| Name | Purpose |
|-----------|-------------------------------------------------|
| `DEBUG` | Enables/disables specific debugging namespaces. |
| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
| `DEBUG_DEPTH` | Object inspection depth. |
| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
__Note:__ The environment variables beginning with `DEBUG_` end up being
converted into an Options object that gets used with `%o`/`%O` formatters.
See the Node.js documentation for
[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
for the complete list.
## Formatters
Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
| Formatter | Representation |
|-----------|----------------|
| `%O` | Pretty-print an Object on multiple lines. |
| `%o` | Pretty-print an Object all on a single line. |
| `%s` | String. |
| `%d` | Number (both integer and float). |
| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
| `%%` | Single percent sign ('%'). This does not consume an argument. |
### Custom formatters
You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
```js
const createDebug = require('debug')
createDebug.formatters.h = (v) => {
return v.toString('hex')
}
// …elsewhere
const debug = createDebug('foo')
debug('this is hex: %h', new Buffer('hello world'))
// foo this is hex: 68656c6c6f20776f726c6421 +0ms
```
## Browser support
You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
if you don't want to build it yourself.
Debug's enable state is currently persisted by `localStorage`.
Consider the situation shown below where you have `worker:a` and `worker:b`,
and wish to debug both. You can enable this using `localStorage.debug`:
```js
localStorage.debug = 'worker:*'
```
And then refresh the page.
```js
a = debug('worker:a');
b = debug('worker:b');
setInterval(function(){
a('doing some work');
}, 1000);
setInterval(function(){
b('doing some work');
}, 1200);
```
#### Web Inspector Colors
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
option. These are WebKit web inspectors, Firefox ([since version
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
and the Firebug plugin for Firefox (any version).
Colored output looks something like:

## Output streams
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
Example _stdout.js_:
```js
var debug = require('debug');
var error = debug('app:error');
// by default stderr is used
error('goes to stderr!');
var log = debug('app:log');
// set this namespace to log via console.log
log.log = console.log.bind(console); // don't forget to bind to console!
log('goes to stdout');
error('still goes to stderr!');
// set all output to go via console.info
// overrides all per-namespace log settings
debug.log = console.info.bind(console);
error('now goes to stdout via console.info');
log('still goes to stdout, but via console.info now');
```

# ms
[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
Use this package to easily convert various time formats to milliseconds.
## Examples
```js
ms('2 days') // 172800000
ms('1d') // 86400000
ms('10h') // 36000000
ms('2.5 hrs') // 9000000
ms('2h') // 7200000
ms('1m') // 60000
ms('5s') // 5000
ms('1y') // 31557600000
ms('100') // 100
```
### Convert from milliseconds
```js
ms(60000) // "1m"
ms(2 * 60000) // "2m"
ms(ms('10 hours')) // "10h"
```
### Time format written-out
```js
ms(60000, { long: true }) // "1 minute"
ms(2 * 60000, { long: true }) // "2 minutes"
ms(ms('10 hours'), { long: true }) // "10 hours"
```
## Features
- Works both in [node](https://nodejs.org) and in the browser.
- If a number is supplied to `ms`, a string with a unit is returned.
- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
## Caught a bug?
1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
2. Link the package to the global module directory: `npm link`
3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
As always, you can run the tests using: `npm test`

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' } });
```
If you have to deal with legacy browsers or services, there's
also support for decoding percent-encoded octets as iso-8859-1:
```javascript
var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' });
assert.deepEqual(oldCharset, { a: '§' });
```
Some services add an initial `utf8=✓` value to forms so that old
Internet Explorer versions are more likely to submit the form as
utf-8. Additionally, the server can check the value against wrong
encodings of the checkmark character and detect that a query string
or `application/x-www-form-urlencoded` body was *not* sent as
utf-8, eg. if the form had an `accept-charset` parameter or the
containing page had a different character set.
**qs** supports this mechanism via the `charsetSentinel` option.
If specified, the `utf8` parameter will be omitted from the
returned object. It will be used to switch to `iso-8859-1`/`utf-8`
mode depending on how the checkmark is encoded.
**Important**: When you specify both the `charset` option and the
`charsetSentinel` option, the `charset` will be overridden when
the request contains a `utf8` parameter from which the actual
charset can be deduced. In that sense the `charset` will behave
as the default charset rather than the authoritative charset.
```javascript
var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', {
charset: 'iso-8859-1',
charsetSentinel: true
});
assert.deepEqual(detectedAsUtf8, { a: 'ø' });
// Browsers encode the checkmark as &#10003; when submitting as iso-8859-1:
var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', {
charset: 'utf-8',
charsetSentinel: true
});
assert.deepEqual(detectedAsIso8859_1, { a: 'ø' });
```
If you want to decode the `&#...;` syntax to the actual character,
you can specify the `interpretNumericEntities` option as well:
```javascript
var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', {
charset: 'iso-8859-1',
interpretNumericEntities: true
});
assert.deepEqual(detectedAsIso8859_1, { a: '☺' });
```
It also works when the charset has been detected in `charsetSentinel`
mode.
### 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'] });
```
You may also use `allowSparse` option to parse sparse arrays:
```javascript
var sparseArray = qs.parse('a[1]=2&a[3]=5', { allowSparse: true });
assert.deepEqual(sparseArray, { a: [, '2', , '5'] });
```
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. This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array.
```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' }] });
```
Some people use comma to join array, **qs** can parse it:
```javascript
var arraysOfObjects = qs.parse('a=b,c', { comma: true })
assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] })
```
(_this cannot convert nested objects, such as `a={b:1},{c:d}`_)
### Parsing primitive/scalar values (numbers, booleans, null, etc)
By default, all values are parsed as strings. This behavior will not change and is explained in [issue #91](https://github.com/ljharb/qs/issues/91).
```javascript
var primitiveValues = qs.parse('a=15&b=true&c=null');
assert.deepEqual(primitiveValues, { a: '15', b: 'true', c: 'null' });
```
If you wish to auto-convert values which look like numbers, booleans, and other values into their primitive counterparts, you can use the [query-types Express JS middleware](https://github.com/xpepermint/query-types) which will auto-convert all request query parameters.
### 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
}})
```
You can encode keys and values using different logic by using the type argument provided to the encoder:
```javascript
var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str, defaultEncoder, charset, type) {
if (type === 'key') {
return // Encoded key
} else if (type === 'value') {
return // Encoded value
}
}})
```
The type argument is also provided to the decoder:
```javascript
var decoded = qs.parse('x=z', { decoder: function (str, defaultDecoder, charset, type) {
if (type === 'key') {
return // Decoded key
} else if (type === 'value') {
return // Decoded value
}
}})
```
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'
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' })
// 'a=b,c'
```
Note: when using `arrayFormat` set to `'comma'`, you can also pass the `commaRoundTrip` option set to `true` or `false`, to append `[]` on single-item arrays, so that they can round trip through a parse.
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');
```
If you're communicating with legacy systems, you can switch to `iso-8859-1`
using the `charset` option:
```javascript
var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' });
assert.equal(iso, '%E6=%E6');
```
Characters that don't exist in `iso-8859-1` will be converted to numeric
entities, similar to what browsers do:
```javascript
var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' });
assert.equal(numeric, 'a=%26%239786%3B');
```
You can use the `charsetSentinel` option to announce the character by
including an `utf8=✓` parameter with the proper encoding if the checkmark,
similar to what Ruby on Rails and others do when submitting forms.
```javascript
var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true });
assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA');
var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' });
assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6');
```
### Dealing with special character sets
By default the encoding and decoding of characters is done in `utf-8`,
and `iso-8859-1` support is also built in via the `charset` parameter.
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');
```
