+
+  Serves pages that contain directory listings for a given path.
+
+## Install
+
+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):
+
+```sh
+$ npm install serve-index
+```
+
+## API
+
+```js
+var serveIndex = require('serve-index')
+```
+
+### serveIndex(path, options)
+
+Returns middlware that serves an index of the directory in the given `path`.
+
+The `path` is based off the `req.url` value, so a `req.url` of `'/some/dir`
+with a `path` of `'public'` will look at `'public/some/dir'`. If you are using
+something like `express`, you can change the URL "base" with `app.use` (see
+the express example).
+
+#### Options
+
+Serve index accepts these properties in the options object.
+
+##### filter
+
+Apply this filter function to files. Defaults to `false`. The `filter` function
+is called for each file, with the signature `filter(filename, index, files, dir)`
+where `filename` is the name of the file, `index` is the array index, `files` is
+the array of files and `dir` is the absolute path the file is located (and thus,
+the directory the listing is for).
+
+##### hidden
+
+Display hidden (dot) files. Defaults to `false`.
+
+##### icons
+
+Display icons. Defaults to `false`.
+
+##### stylesheet
+
+Optional path to a CSS stylesheet. Defaults to a built-in stylesheet.
+
+##### template
+
+Optional path to an HTML template or a function that will render a HTML
+string. Defaults to a built-in template.
+
+When given a string, the string is used as a file path to load and then the
+following tokens are replaced in templates:
+
+  * `{directory}` with the name of the directory.
+  * `{files}` with the HTML of an unordered list of file links.
+  * `{linked-path}` with the HTML of a link to the directory.
+  * `{style}` with the specified stylesheet and embedded images.
+
+When given as a function, the function is called as `template(locals, callback)`
+and it needs to invoke `callback(error, htmlString)`. The following are the
+provided locals:
+
+  * `directory` is the directory being displayed (where `/` is the root).
+  * `displayIcons` is a Boolean for if icons should be rendered or not.
+  * `fileList` is a sorted array of files in the directory. The array contains
+    objects with the following properties:
+    - `name` is the relative name for the file.
+    - `stat` is a `fs.Stats` object for the file.
+  * `path` is the full filesystem path to `directory`.
+  * `style` is the default stylesheet or the contents of the `stylesheet` option.
+  * `viewName` is the view name provided by the `view` option.
+
+##### view
+
+Display mode. `tiles` and `details` are available. Defaults to `tiles`.
+
+## Examples
+
+### Serve directory indexes with vanilla node.js http server
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveIndex = require('serve-index')
+var serveStatic = require('serve-static')
+
+// Serve directory indexes for public/ftp folder (with icons)
+var index = serveIndex('public/ftp', {'icons': true})
+
+// Serve up public/ftp folder files
+var serve = serveStatic('public/ftp')
+
+// Create server
+var server = http.createServer(function onRequest(req, res){
+  var done = finalhandler(req, res)
+  serve(req, res, function onNext(err) {
+    if (err) return done(err)
+    index(req, res, done)
+  })
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serve directory indexes with express
+
+```js
+var express    = require('express')
+var serveIndex = require('serve-index')
+
+var app = express()
+
+// Serve URLs like /ftp/thing as public/ftp/thing
+// The express.static serves the file contents
+// The serveIndex is this module serving the directory
+app.use('/ftp', express.static('public/ftp'), serveIndex('public/ftp', {'icons': true}))
+
+// Listen
+app.listen(3000)
+```

+
+
+
+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:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## 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');
+```

+Deprecate all the things
+
+> With great modules comes great responsibility; mark things deprecated!
+
+## Install
+
+This module is installed directly using `npm`:
+
+```sh
+$ npm install depd
+```
+
+This module can also be bundled with systems like
+[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/),
+though by default this module will alter it's API to no longer display or
+track deprecations.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var deprecate = require('depd')('my-module')
+```
+
+This library allows you to display deprecation messages to your users.
+This library goes above and beyond with deprecation warnings by
+introspection of the call stack (but only the bits that it is interested
+in).
+
+Instead of just warning on the first invocation of a deprecated
+function and never again, this module will warn on the first invocation
+of a deprecated function per unique call site, making it ideal to alert
+users of all deprecated uses across the code base, rather than just
+whatever happens to execute first.
+
+The deprecation warnings from this module also include the file and line
+information for the call into the module that the deprecated function was
+in.
+
+**NOTE** this library has a similar interface to the `debug` module, and
+this module uses the calling file to get the boundary for the call stacks,
+so you should always create a new `deprecate` object in each file and not
+within some central file.
+
+### depd(namespace)
+
+Create a new deprecate function that uses the given namespace name in the
+messages and will display the call site prior to the stack entering the
+file this function was called from. It is highly suggested you use the
+name of your module as the namespace.
+
+### deprecate(message)
+
+Call this function from deprecated code to display a deprecation message.
+This message will appear once per unique caller site. Caller site is the
+first call site in the stack in a different file from the caller of this
+function.
+
+If the message is omitted, a message is generated for you based on the site
+of the `deprecate()` call and will display the name of the function called,
+similar to the name displayed in a stack trace.
+
+### deprecate.function(fn, message)
+
+Call this function to wrap a given function in a deprecation message on any
+call to the function. An optional message can be supplied to provide a custom
+message.
+
+### deprecate.property(obj, prop, message)
+
+Call this function to wrap a given property on object in a deprecation message
+on any accessing or setting of the property. An optional message can be supplied
+to provide a custom message.
+
+The method must be called on the object where the property belongs (not
+inherited from the prototype).
+
+If the property is a data descriptor, it will be converted to an accessor
+descriptor in order to display the deprecation message.
+
+### process.on('deprecation', fn)
+
+This module will allow easy capturing of deprecation errors by emitting the
+errors as the type "deprecation" on the global `process`. If there are no
+listeners for this type, the errors are written to STDERR as normal, but if
+there are any listeners, nothing will be written to STDERR and instead only
+emitted. From there, you can write the errors in a different format or to a
+logging source.
+
+The error represents the deprecation and is emitted only once with the same
+rules as writing to STDERR. The error has the following properties:
+
+  - `message` - This is the message given by the library
+  - `name` - This is always `'DeprecationError'`
+  - `namespace` - This is the namespace the deprecation came from
+  - `stack` - This is the stack of the call to the deprecated thing
+
+Example `error.stack` output:
+
+```
+DeprecationError: my-cool-module deprecated oldfunction
+    at Object.<anonymous> ([eval]-wrapper:6:22)
+    at Module._compile (module.js:456:26)
+    at evalScript (node.js:532:25)
+    at startup (node.js:80:7)
+    at node.js:902:3
+```
+
+### process.env.NO_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
+is provided as a quick solution to silencing deprecation warnings from being
+output. The format of this is similar to that of `DEBUG`:
+
+```sh
+$ NO_DEPRECATION=my-module,othermod node app.js
+```
+
+This will suppress deprecations from being output for "my-module" and "othermod".
+The value is a list of comma-separated namespaces. To suppress every warning
+across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--no-deprecation` to the `node` executable will suppress
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not suppress the deperecations given to any "deprecation"
+event listeners, just the output to STDERR.
+
+### process.env.TRACE_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
+is provided as a solution to getting more detailed location information in deprecation
+warnings by including the entire stack trace. The format of this is the same as
+`NO_DEPRECATION`:
+
+```sh
+$ TRACE_DEPRECATION=my-module,othermod node app.js
+```
+
+This will include stack traces for deprecations being output for "my-module" and
+"othermod". The value is a list of comma-separated namespaces. To trace every
+warning across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--trace-deprecation` to the `node` executable will trace
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
+
+## Display
+
+![message](files/message.png)
+
+When a user calls a function in your library that you mark deprecated, they
+will see the following written to STDERR (in the given colors, similar colors
+and layout to the `debug` module):
+
+```
+bright cyan    bright yellow
+|              |          reset       cyan

+               |          deprecation message
+               the word "deprecated"
+```
+
+If the user redirects their STDERR to a file or somewhere that does not support
+colors, they see (similar layout to the `debug` module):
+
+```

+|                             |              |          |              |

+                                             the word "deprecated"
+```
+
+## Examples
+
+### Deprecating all calls to a function
+
+This will display a deprecated message about "oldfunction" being deprecated
+from "my-module" on STDERR.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+// message automatically derived from function name
+// Object.oldfunction
+exports.oldfunction = deprecate.function(function oldfunction () {
+  // all calls to function are deprecated
+})
+
+// specific message
+exports.oldfunction = deprecate.function(function () {
+  // all calls to function are deprecated
+}, 'oldfunction')
+```
+
+### Conditionally deprecating a function call
+
+This will display a deprecated message about "weirdfunction" being deprecated
+from "my-module" on STDERR when called with less than 2 arguments.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  }
+}
+```
+
+When calling `deprecate` as a function, the warning is counted per call site
+within your own module, so you can display different deprecations depending
+on different situations and the users will still get all the warnings:
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  } else if (typeof arguments[0] !== 'string') {
+    // calls with non-string first argument are deprecated
+    deprecate('weirdfunction non-string first arg')
+  }
+}
+```
+
+### Deprecating property access
+
+This will display a deprecated message about "oldprop" being deprecated
+from "my-module" on STDERR when accessed. A deprecation will be displayed
+when setting the value and when getting the value.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.oldprop = 'something'
+
+// message automatically derives from property name
+deprecate.property(exports, 'oldprop')
+
+// explicit message
+deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
+```

+
+Create HTTP errors for Express, Koa, Connect, etc. with ease.
+
+## Install
+
+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 http-errors
+```
+
+## Example
+
+```js
+var createError = require('http-errors')
+var express = require('express')
+var app = express()
+
+app.use(function (req, res, next) {
+  if (!req.user) return next(createError(401, 'Please login to view this page.'))
+  next()
+})
+```
+
+## API
+
+This is the current API, currently extracted from Koa and subject to change.
+
+All errors inherit from JavaScript `Error` and the exported `createError.HttpError`.
+
+### Error Properties
+
+- `expose` - can be used to signal if `message` should be sent to the client,
+  defaulting to `false` when `status` >= 500
+- `headers` - can be an object of header names to values to be sent to the
+  client, defaulting to `undefined`. When defined, the key names should all
+  be lower-cased
+- `message` - the traditional error message, which should be kept short and all
+  single line
+- `status` - the status code of the error, mirroring `statusCode` for general
+  compatibility
+- `statusCode` - the status code of the error, defaulting to `500`
+
+### createError([status], [message], [properties])
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var err = createError(404, 'This video does not exist!')
+```
+
+- `status: 500` - the status code as a number
+- `message` - the message of the error, defaulting to node's text for that status code.
+- `properties` - custom properties to attach to the object
+
+### new createError\[code || name\](\[msg]\))
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var err = new createError.NotFound()
+```
+
+- `code` - the status code as a number
+- `name` - the name of the error as a "bumpy case", i.e. `NotFound` or `InternalServerError`.
+

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+# 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`

+# Polyfill for `Object.setPrototypeOf`
+
+A simple cross platform implementation to set the prototype of an instianted object.  Supports all modern browsers and at least back to IE8.
+
+## Usage:
+
+```
+$ npm install --save setprototypeof
+```
+
+```javascript
+var setPrototypeOf = require('setprototypeof');
+
+var obj = {};
+setPrototypeOf(obj, {
+	foo: function() {
+		return 'bar';
+	}
+});
+obj.foo(); // bar
+```
+
+TypeScript is also supported:
+```typescript
+import setPrototypeOf = require('setprototypeof');
+```

+
+HTTP status utility for node.
+
+This module provides a list of status codes and messages sourced from
+a few different projects:
+
+  * The [IANA Status Code Registry](https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml)
+  * The [Node.js project](https://nodejs.org/)
+  * The [NGINX project](https://www.nginx.com/)
+  * The [Apache HTTP Server project](https://httpd.apache.org/)
+
+## 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):
+
+```sh
+$ npm install statuses
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var status = require('statuses')
+```
+
+### var code = status(Integer || String)
+
+If `Integer` or `String` is a valid HTTP code or status message, then the
+appropriate `code` will be returned. Otherwise, an error will be thrown.
+
+<!-- eslint-disable no-undef -->
+
+```js
+status(403) // => 403
+status('403') // => 403
+status('forbidden') // => 403
+status('Forbidden') // => 403
+status(306) // throws, as it's not supported by node.js
+```
+
+### status.STATUS_CODES
+
+Returns an object which maps status codes to status messages, in
+the same format as the
+[Node.js http module](https://nodejs.org/dist/latest/docs/api/http.html#http_http_status_codes).
+
+### status.codes
+
+Returns an array of all the status codes as `Integer`s.
+
+### var msg = status[code]
+
+Map of `code` to `status message`. `undefined` for invalid `code`s.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status[404] // => 'Not Found'
+```
+
+### var code = status[msg]
+
+Map of `status message` to `code`. `msg` can either be title-cased or
+lower-cased. `undefined` for invalid `status message`s.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status['not found'] // => 404
+status['Not Found'] // => 404
+```
+
+### status.redirect[code]
+
+Returns `true` if a status code is a valid redirect status.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.redirect[200] // => undefined
+status.redirect[301] // => true
+```
+
+### status.empty[code]
+
+Returns `true` if a status code expects an empty body.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.empty[200] // => undefined
+status.empty[204] // => true
+status.empty[304] // => true
+```
+
+### status.retry[code]
+
+Returns `true` if you should retry the rest.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.retry[501] // => undefined
+status.retry[503] // => true
+```
