+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## 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 accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+# After [![Build Status][1]][2]
+
+Invoke callback after n calls
+
+## Status: production ready
+
+## Example
+
+```js
+var after = require("after")
+var db = require("./db") // some db.
+
+var updateUser = function (req, res) {
+  // use after to run two tasks in parallel,
+  // namely get request body and get session
+  // then run updateUser with the results
+  var next = after(2, updateUser)
+  var results = {}
+  
+  getJSONBody(req, res, function (err, body) {
+    if (err) return next(err)
+    
+    results.body = body
+    next(null, results)
+  })
+  
+  getSessionUser(req, res, function (err, user) {
+    if (err) return next(err)
+    
+    results.user = user
+    next(null, results)
+  })
+  
+  // now do the thing!
+  function updateUser(err, result) {
+    if (err) {
+      res.statusCode = 500
+      return res.end("Unexpected Error")
+    }
+    
+    if (!result.user || result.user.role !== "admin") {
+      res.statusCode = 403
+      return res.end("Permission Denied")
+    }
+    
+    db.put("users:" + req.params.userId, result.body, function (err) {
+      if (err) {
+        res.statusCode = 500
+        return res.end("Unexpected Error")
+      }
+      
+      res.statusCode = 200
+      res.end("Ok")  
+    })   
+  }
+}
+```
+
+## Naive Example
+
+```js
+var after = require("after")
+    , next = after(3, logItWorks)
+
+next()
+next()
+next() // it works
+
+function logItWorks() {
+    console.log("it works!")
+}
+```
+
+## Example with error handling
+
+```js
+var after = require("after")
+    , next = after(3, logError)
+
+next()
+next(new Error("oops")) // logs oops
+next() // does nothing
+
+// This callback is only called once.
+// If there is an error the callback gets called immediately
+// this avoids the situation where errors get lost.
+function logError(err) {
+    console.log(err)
+}
+```

+# Async-Limiter
+
+A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
+
+[![npm](http://img.shields.io/npm/v/async-limiter.svg?style=flat-square)](http://www.npmjs.org/async-limiter)
+[![tests](https://img.shields.io/travis/STRML/async-limiter.svg?style=flat-square&branch=master)](https://travis-ci.org/STRML/async-limiter)
+[![coverage](https://img.shields.io/coveralls/STRML/async-limiter.svg?style=flat-square&branch=master)](https://coveralls.io/r/STRML/async-limiter)
+
+This module exports a class `Limiter` that implements some of the `Array` API.
+Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
+
+## Motivation
+
+Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
+run at infinite concurrency.
+
+In this case, it is actually faster, and takes far less memory, to limit concurrency.
+
+This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
+make this module faster or lighter, but new functionality is not desired.
+
+Style should confirm to nodejs/node style.
+
+## Example
+
+``` javascript
+var Limiter = require('async-limiter')
+
+var t = new Limiter({concurrency: 2});
+var results = []
+
+// add jobs using the familiar Array API
+t.push(function (cb) {
+  results.push('two')
+  cb()
+})
+
+t.push(
+  function (cb) {
+    results.push('four')
+    cb()
+  },
+  function (cb) {
+    results.push('five')
+    cb()
+  }
+)
+
+t.unshift(function (cb) {
+  results.push('one')
+  cb()
+})
+
+t.splice(2, 0, function (cb) {
+  results.push('three')
+  cb()
+})
+
+// Jobs run automatically. If you want a callback when all are done,
+// call 'onDone()'.
+t.onDone(function () {
+  console.log('all done:', results)
+})
+```
+
+## Zlib Example
+
+```js
+const zlib = require('zlib');
+const Limiter = require('async-limiter');
+
+const message = {some: "data"};
+const payload = new Buffer(JSON.stringify(message));
+
+// Try with different concurrency values to see how this actually
+// slows significantly with higher concurrency!
+//
+// 5:        1398.607ms
+// 10:       1375.668ms
+// Infinity: 4423.300ms
+//
+const t = new Limiter({concurrency: 5});
+function deflate(payload, cb) {
+  t.push(function(done) {
+    zlib.deflate(payload, function(err, buffer) {
+      done();
+      cb(err, buffer);
+    });
+  });
+}
+
+console.time('deflate');
+for(let i = 0; i < 30000; ++i) {
+  deflate(payload, function (err, buffer) {});
+}
+t.onDone(function() {
+  console.timeEnd('deflate');
+});
+```
+
+## Install
+
+`npm install async-limiter`
+
+## Test
+
+`npm test`
+
+## API
+
+### `var t = new Limiter([opts])`
+Constructor. `opts` may contain inital values for:
+* `t.concurrency`
+
+## Instance methods
+
+### `t.onDone(fn)`
+`fn` will be called once and only once, when the queue is empty.
+
+## Instance methods mixed in from `Array`
+Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
+### `t.push(element1, ..., elementN)`
+### `t.unshift(element1, ..., elementN)`
+### `t.splice(index , howMany[, element1[, ...[, elementN]]])`
+
+## Properties
+### `t.concurrency`
+Max number of jobs the queue should process concurrently, defaults to `Infinity`.
+
+### `t.length`
+Jobs pending + jobs to process (readonly).

+# backo
+
+  Simple exponential backoff because the others seem to have weird abstractions.
+
+## Installation
+
+```
+$ npm install backo
+```
+
+## Options
+
+ - `min` initial timeout in milliseconds [100]
+ - `max` max timeout [10000]
+ - `jitter` [0]
+ - `factor` [2]
+
+## Example
+
+```js
+var Backoff = require('backo');
+var backoff = new Backoff({ min: 100, max: 20000 });
+
+setTimeout(function(){
+  something.reconnect();
+}, backoff.duration());
+
+// later when something works
+backoff.reset()

+base64id
+========
+
+Node.js module that generates a base64 id.
+
+Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4.
+
+To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes.
+
+## Installation
+
+   $ npm install base64id
+
+## Usage
+
+   var base64id = require('base64id');
+
+   var id = base64id.generateId();

+# better-assert
+
+  Better c-style assertions using [callsite](https://github.com/visionmedia/callsite) for
+  self-documenting failure messages.
+
+## Installation
+
+    $ npm install better-assert
+
+## Example
+
+ By default assertions are enabled, however the __NO_ASSERT__ environment variable 
+ will deactivate them when truthy.
+
+```js
+var assert = require('better-assert');
+
+test();
+
+function test() {
+  var user = { name: 'tobi' };
+  assert('tobi' == user.name);
+  assert('number' == typeof user.age);
+}
+
+AssertionError: 'number' == typeof user.age

+![bignumber.js](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/bignumberjs.png)
+
+A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.
+
+[![Build Status](https://travis-ci.org/MikeMcl/bignumber.js.svg)](https://travis-ci.org/MikeMcl/bignumber.js)
+
+<br />
+
+## Features
+
+  - Integers and decimals
+  - Simple API but full-featured
+  - Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
+  - 8 KB minified and gzipped
+  - Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
+  - Includes a `toFraction` and a correctly-rounded `squareRoot` method
+  - Supports cryptographically-secure pseudo-random number generation
+  - No dependencies
+  - Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
+  - Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
+
+![API](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/API.png)
+
+If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
+It's less than half the size but only works with decimal numbers and only has half the methods.
+It also does not allow `NaN` or `Infinity`, or have the configuration options of this library.
+
+See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
+
+## Load
+
+The library is the single JavaScript file *bignumber.js* (or minified, *bignumber.min.js*).
+
+Browser:
+
+```html
+<script src='path/to/bignumber.js'></script>
+```
+
+[Node.js](http://nodejs.org):
+
+```bash
+$ npm install bignumber.js
+```
+
+```javascript
+const BigNumber = require('bignumber.js');
+```
+
+ES6 module:
+
+```javascript
+import BigNumber from "./bignumber.mjs"
+```
+
+AMD loader libraries such as [requireJS](http://requirejs.org/):
+
+```javascript
+require(['bignumber'], function(BigNumber) {
+    // Use BigNumber here in local scope. No global BigNumber.
+});
+```
+
+## Use
+
+The library exports a single constructor function, [`BigNumber`](http://mikemcl.github.io/bignumber.js/#bignumber), which accepts a value of type Number, String or BigNumber,
+
+```javascript
+let x = new BigNumber(123.4567);
+let y = BigNumber('123456.7e-3');
+let z = new BigNumber(x);
+x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z);      // true
+```
+
+To get the string value of a BigNumber use [`toString()`](http://mikemcl.github.io/bignumber.js/#toS) or [`toFixed()`](http://mikemcl.github.io/bignumber.js/#toFix). Using `toFixed()` prevents exponential notation being returned, no matter how large or small the value.
+
+```javascript
+let x = new BigNumber('1111222233334444555566');
+x.toString();                       // "1.111222233334444555566e+21"
+x.toFixed();                        // "1111222233334444555566"
+```
+
+If the limited precision of Number values is not well understood, it is recommended to create BigNumbers from String values rather than Number values to avoid a potential loss of precision.
+
+*In all further examples below, `let`, semicolons and `toString` calls are not shown. If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
+
+```javascript
+// Precision loss from using numeric literals with more than 15 significant digits.
+new BigNumber(1.0000000000000001)         // '1'
+new BigNumber(88259496234518.57)          // '88259496234518.56'
+new BigNumber(99999999999999999999)       // '100000000000000000000'
+
+// Precision loss from using numeric literals outside the range of Number values.
+new BigNumber(2e+308)                     // 'Infinity'
+new BigNumber(1e-324)                     // '0'
+
+// Precision loss from the unexpected result of arithmetic with Number values.
+new BigNumber(0.7 + 0.1)                  // '0.7999999999999999'
+```
+
+When creating a BigNumber from a Number, note that a BigNumber is created from a Number's decimal `toString()` value not from its underlying binary value. If the latter is required, then pass the Number's `toString(2)` value and specify base 2.
+
+```javascript
+new BigNumber(Number.MAX_VALUE.toString(2), 2)
+```
+
+BigNumbers can be created from values in bases from 2 to 36. See [`ALPHABET`](http://mikemcl.github.io/bignumber.js/#alphabet) to extend this range.
+
+```javascript
+a = new BigNumber(1011, 2)          // "11"
+b = new BigNumber('zz.9', 36)       // "1295.25"
+c = a.plus(b)                       // "1306.25"
+```
+
+Performance is better if base 10 is NOT specified for decimal values. Only specify base 10 when it is desired that the number of decimal places of the input value be limited to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.
+
+A BigNumber is immutable in the sense that it is not changed by its methods.
+
+```javascript
+0.3 - 0.1                           // 0.19999999999999998
+x = new BigNumber(0.3)
+x.minus(0.1)                        // "0.2"
+x                                   // "0.3"
+```
+
+The methods that return a BigNumber can be chained.
+
+```javascript
+x.dividedBy(y).plus(z).times(9)
+x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').integerValue()
+```
+
+Some of the longer method names have a shorter alias.
+
+```javascript
+x.squareRoot().dividedBy(y).exponentiatedBy(3).isEqualTo(x.sqrt().div(y).pow(3))    // true
+x.modulo(y).multipliedBy(z).eq(x.mod(y).times(z))                                   // true
+```
+
+As with JavaScript's Number type, there are [`toExponential`](http://mikemcl.github.io/bignumber.js/#toE), [`toFixed`](http://mikemcl.github.io/bignumber.js/#toFix) and [`toPrecision`](http://mikemcl.github.io/bignumber.js/#toP) methods.
+
+```javascript
+x = new BigNumber(255.5)
+x.toExponential(5)                  // "2.55500e+2"
+x.toFixed(5)                        // "255.50000"
+x.toPrecision(5)                    // "255.50"
+x.toNumber()                        //  255.5
+```
+
+ A base can be specified for [`toString`](http://mikemcl.github.io/bignumber.js/#toS). Performance is better if base 10 is NOT specified, i.e. use `toString()` not `toString(10)`. Only specify base 10 when it is desired that the number of decimal places be limited to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.
+
+ ```javascript
+ x.toString(16)                     // "ff.8"
+ ```
+
+There is a [`toFormat`](http://mikemcl.github.io/bignumber.js/#toFor) method which may be useful for internationalisation.
+
+```javascript
+y = new BigNumber('1234567.898765')
+y.toFormat(2)                       // "1,234,567.90"
+```
+
+The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `set` or `config` method of the `BigNumber` constructor.
+
+The other arithmetic operations always give the exact result.
+
+```javascript
+BigNumber.set({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
+
+x = new BigNumber(2)
+y = new BigNumber(3)
+z = x.dividedBy(y)                        // "0.6666666667"
+z.squareRoot()                            // "0.8164965809"
+z.exponentiatedBy(-3)                     // "3.3749999995"
+z.toString(2)                             // "0.1010101011"
+z.multipliedBy(z)                         // "0.44444444448888888889"
+z.multipliedBy(z).decimalPlaces(10)       // "0.4444444445"
+```
+
+There is a [`toFraction`](http://mikemcl.github.io/bignumber.js/#toFr) method with an optional *maximum denominator* argument
+
+```javascript
+y = new BigNumber(355)
+pi = y.dividedBy(113)               // "3.1415929204"
+pi.toFraction()                     // [ "7853982301", "2500000000" ]
+pi.toFraction(1000)                 // [ "355", "113" ]
+```
+
+and [`isNaN`](http://mikemcl.github.io/bignumber.js/#isNaN) and [`isFinite`](http://mikemcl.github.io/bignumber.js/#isF) methods, as `NaN` and `Infinity` are valid `BigNumber` values.
+
+```javascript
+x = new BigNumber(NaN)                                           // "NaN"
+y = new BigNumber(Infinity)                                      // "Infinity"
+x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite()        // true
+```
+
+The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
+
+```javascript
+x = new BigNumber(-123.456);
+x.c                                 // [ 123, 45600000000000 ]  coefficient (i.e. significand)
+x.e                                 // 2                        exponent
+x.s                                 // -1                       sign
+```
+
+For advanced usage, multiple BigNumber constructors can be created, each with their own independent configuration.
+
+```javascript
+// Set DECIMAL_PLACES for the original BigNumber constructor
+BigNumber.set({ DECIMAL_PLACES: 10 })
+
+// Create another BigNumber constructor, optionally passing in a configuration object
+BN = BigNumber.clone({ DECIMAL_PLACES: 5 })
+
+x = new BigNumber(1)
+y = new BN(1)
+
+x.div(3)                            // '0.3333333333'
+y.div(3)                            // '0.33333'
+```
+
+For further information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
+
+## Test
+
+The *test/modules* directory contains the test scripts for each method.
+
+The tests can be run with Node.js or a browser. For Node.js use
+
+    $ npm test
+
+or
+
+    $ node test/test
+
+To test a single method, use, for example
+
+    $ node test/methods/toFraction
+
+For the browser, open *test/test.html*.
+
+## Build
+
+For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
+
+    npm install uglify-js -g
+
+then
+
+    npm run build
+
+will create *bignumber.min.js*.
+
+A source map will also be created in the root directory.

+# Blob
+
+A cross-browser `Blob` that falls back to `BlobBuilder` when appropriate.
+If neither is available, it exports `undefined`.
+
+## Installation
+
+``` bash
+$ npm install blob
+```
+
+## Example
+
+``` js
+var Blob = require('blob');
+var b = new Blob(['hi', 'constructing', 'a', 'blob']);
+```

+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
+
+<!-- eslint-disable no-unused-vars -->
+
+```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 depending on the error
+condition during parsing. 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 emitted, 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.
+
+### 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'`.
+
+### 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' }))
+```

+# buffer-equal-constant-time
+
+Constant-time `Buffer` comparison for node.js.  Should work with browserify too.
+
+[![Build Status](https://travis-ci.org/goinstant/buffer-equal-constant-time.png?branch=master)](https://travis-ci.org/goinstant/buffer-equal-constant-time)
+
+```sh
+  npm install buffer-equal-constant-time
+```
+
+# Usage
+
+```js
+  var bufferEq = require('buffer-equal-constant-time');
+
+  var a = new Buffer('asdf');
+  var b = new Buffer('asdf');
+  if (bufferEq(a,b)) {
+    // the same!
+  } else {
+    // different in at least one byte!
+  }
+```
+
+If you'd like to install an `.equal()` method onto the node.js `Buffer` and
+`SlowBuffer` prototypes:
+
+```js
+  require('buffer-equal-constant-time').install();
+
+  var a = new Buffer('asdf');
+  var b = new Buffer('asdf');
+  if (a.equal(b)) {
+    // the same!
+  } else {
+    // different in at least one byte!
+  }
+```
+
+To get rid of the installed `.equal()` method, call `.restore()`:
+
+```js
+  require('buffer-equal-constant-time').restore();
+```
