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.
This is a Node.js module available through the
npm registry. Installation is done using the
npm install
command:
$ npm install raw-body
This module includes a TypeScript
declaration file to enable auto complete in compatible editors and type
information for TypeScript projects. This module depends on the Node.js
types, so install @types/node
:
$ npm install @types/node
var getRawBody = require('raw-body')
Returns a promise if no callback specified and global Promise
exists.
Options:
length
- The 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.
This is the number of bytes or any string format supported by
bytes,
for example 1000
, '500kb'
or '3mb'
.
If the body ends up being larger than this limit,
a 413
error code is returned.encoding
- The encoding to use to decode the body into a string.
By default, a Buffer
instance will be returned when no encoding is specified.
Most likely, you want utf-8
, so setting encoding
to true
will decode as utf-8
.
You can use any type of encoding supported by iconv-lite.You can also pass a string in place of options to just specify the encoding.
If an error occurs, the stream will be paused, everything unpiped,
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.
This module creates errors depending on the error condition during reading. The error may be an error from the underlying Node.js implementation, but is otherwise an error created by this module, which has the following attributes:
limit
- the limit in byteslength
and expected
- the expected length of the streamreceived
- the received bytesencoding
- the invalid encodingstatus
and statusCode
- the corresponding status code for the errortype
- the error typeThe errors from this module have a type
property which allows for the progamatic
determination of the type of error returned.
This error will occur when the encoding
option is specified, but the value does
not map to an encoding supported by the iconv-lite
module.
This error will occur when the limit
option is specified, but the stream has
an entity that is larger.
This error will occur when the request stream is aborted by the client before reading the body has finished.
This error will occur when the length
option is specified, but the stream has
emitted more bytes.
This error will occur when the given stream has an encoding set on it, making it
a decoded stream. The stream should not have an encoding set and is expected to
emit Buffer
objects.
var contentType = require('content-type')
var express = require('express')

var app = express()

To use this library as a promise, simply omit the callback
and a promise is
returned, provided that a global Promise
is defined.
