+[![NPM version](https://badge.fury.io/js/method-override.svg)](http://badge.fury.io/js/raw-body)
+[![Build Status](https://travis-ci.org/stream-utils/raw-body.svg?branch=master)](https://travis-ci.org/stream-utils/raw-body)
+[![Coverage Status](https://img.shields.io/coveralls/stream-utils/raw-body.svg?branch=master)](https://coveralls.io/r/stream-utils/raw-body)
+
+Gets the entire buffer of a stream either as a `Buffer` or a string.
+Validates the stream's length against an expected length and maximum limit.
+Ideal for parsing request bodies.
+
+## API
+
+```js
+var getRawBody = require('raw-body')
+
+app.use(function (req, res, next) {
+  getRawBody(req, {
+    length: req.headers['content-length'],
+    limit: '1mb',
+    encoding: 'utf8'
+  }, function (err, string) {
+    if (err)
+      return next(err)
+
+    req.text = string
+    next()
+  })
+})
+```
+
+or in a Koa generator:
+
+```js
+app.use(function* (next) {
+  var string = yield getRawBody(this.req, {
+    length: this.length,
+    limit: '1mb',
+    encoding: 'utf8'
+  })
+})
+```
+
+### getRawBody(stream, [options], [callback])
+
+Returns a thunk for yielding with generators.
+
+Options:
+
+- `length` - The length length of the stream.
+  If the contents of the stream do not add up to this length,
+  an `400` error code is returned.
+- `limit` - The byte limit of the body.
+  If the body ends up being larger than this limit,
+  a `413` error code is returned.
+- `encoding` - The requested encoding.
+  By default, a `Buffer` instance will be returned.
+  Most likely, you want `utf8`.
+  You can use any type of encoding supported by [StringDecoder](http://nodejs.org/api/string_decoder.html).
+  You can also pass `true` which sets it to the default `utf8`
+
+`callback(err, res)`:
+
+- `err` - the following attributes will be defined if applicable:
+
+    - `limit` - the limit in bytes
+    - `length` and `expected` - the expected length of the stream
+    - `received` - the received bytes
+    - `status` and `statusCode` - the corresponding status code for the error
+    - `type` - either `entity.too.large`, `request.size.invalid`, or `stream.encoding.set`
+
+- `res` - the result, either as a `String` if an encoding was set or a `Buffer` otherwise.
+
+If an error occurs, the stream will be paused,
+and you are responsible for correctly disposing the stream.
+For HTTP requests, no handling is required if you send a response.
+For streams that use file descriptors, you should `stream.destroy()` or `stream.close()` to prevent leaks.
