# Description
A node.js module for parsing incoming HTML form data.
Changes (breaking or otherwise) in v1.0.0 can be found [here](https://github.com/mscdex/busboy/issues/266).
# Requirements
* [node.js](http://nodejs.org/) -- v10.16.0 or newer
# Install
npm install busboy
# Examples
* Parsing (multipart) with default options:
```js
const http = require('http');
const busboy = require('busboy');
http.createServer((req, res) => {
if (req.method === 'POST') {
console.log('POST request');
const bb = busboy({ headers: req.headers });
bb.on('file', (name, file, info) => {
const { filename, encoding, mimeType } = info;
console.log(
`File [${name}]: filename: %j, encoding: %j, mimeType: %j`,
filename,
encoding,
mimeType
);
file.on('data', (data) => {
console.log(`File [${name}] got ${data.length} bytes`);
}).on('close', () => {
console.log(`File [${name}] done`);
});
});
bb.on('field', (name, val, info) => {
console.log(`Field [${name}]: value: %j`, val);
});
bb.on('close', () => {
console.log('Done parsing form!');
res.writeHead(303, { Connection: 'close', Location: '/' });
res.end();
});
req.pipe(bb);
} else if (req.method === 'GET') {
res.writeHead(200, { Connection: 'close' });
res.end(`
<html>
<head></head>
<body>
<form method="POST" enctype="multipart/form-data">
<input type="file" name="filefield"><br />
<input type="text" name="textfield"><br />
<input type="submit">
</form>
</body>
</html>
`);
}
}).listen(8000, () => {
console.log('Listening for requests');
});
// Example output:
//
// Listening for requests
// < ... form submitted ... >
// POST request
// File [filefield]: filename: "logo.jpg", encoding: "binary", mime: "image/jpeg"
// File [filefield] got 11912 bytes
// Field [textfield]: value: "testing! :-)"
// File [filefield] done
// Done parsing form!
```
* Save all incoming files to disk:
```js
const { randomFillSync } = require('crypto');
const fs = require('fs');
const http = require('http');
const os = require('os');
const path = require('path');
const busboy = require('busboy');
const random = (() => {
const buf = Buffer.alloc(16);
return () => randomFillSync(buf).toString('hex');
})();
http.createServer((req, res) => {
if (req.method === 'POST') {
const bb = busboy({ headers: req.headers });
bb.on('file', (name, file, info) => {
const saveTo = path.join(os.tmpdir(), `busboy-upload-${random()}`);
file.pipe(fs.createWriteStream(saveTo));
});
bb.on('close', () => {
res.writeHead(200, { 'Connection': 'close' });
res.end(`That's all folks!`);
});
req.pipe(bb);
return;
}
res.writeHead(404);
res.end();
}).listen(8000, () => {
console.log('Listening for requests');
});
```
# API
## Exports
`busboy` exports a single function:
**( _function_ )**(< _object_ >config) - Creates and returns a new _Writable_ form parser stream.
* Valid `config` properties:
* **headers** - _object_ - These are the HTTP headers of the incoming request, which are used by individual parsers.
* **highWaterMark** - _integer_ - highWaterMark to use for the parser stream. **Default:** node's _stream.Writable_ default.
* **fileHwm** - _integer_ - highWaterMark to use for individual file streams. **Default:** node's _stream.Readable_ default.
* **defCharset** - _string_ - Default character set to use when one isn't defined. **Default:** `'utf8'`.
* **defParamCharset** - _string_ - For multipart forms, the default character set to use for values of part header parameters (e.g. filename) that are not extended parameters (that contain an explicit charset). **Default:** `'latin1'`.
* **preservePath** - _boolean_ - If paths in filenames from file parts in a `'multipart/form-data'` request shall be preserved. **Default:** `false`.
* **limits** - _object_ - Various limits on incoming data. Valid properties are:
* **fieldNameSize** - _integer_ - Max field name size (in bytes). **Default:** `100`.
* **fieldSize** - _integer_ - Max field value size (in bytes). **Default:** `1048576` (1MB).
* **fields** - _integer_ - Max number of non-file fields. **Default:** `Infinity`.
* **fileSize** - _integer_ - For multipart forms, the max file size (in bytes). **Default:** `Infinity`.
* **files** - _integer_ - For multipart forms, the max number of file fields. **Default:** `Infinity`.
* **parts** - _integer_ - For multipart forms, the max number of parts (fields + files). **Default:** `Infinity`.
* **headerPairs** - _integer_ - For multipart forms, the max number of header key-value pairs to parse. **Default:** `2000` (same as node's http module).
This function can throw exceptions if there is something wrong with the values in `config`. For example, if the Content-Type in `headers` is missing entirely, is not a supported type, or is missing the boundary for `'multipart/form-data'` requests.
## (Special) Parser stream events
* **file**(< _string_ >name, < _Readable_ >stream, < _object_ >info) - Emitted for each new file found. `name` contains the form field name. `stream` is a _Readable_ stream containing the file's data. No transformations/conversions (e.g. base64 to raw binary) are done on the file's data. `info` contains the following properties:
* `filename` - _string_ - If supplied, this contains the file's filename. **WARNING:** You should almost _never_ use this value as-is (especially if you are using `preservePath: true` in your `config`) as it could contain malicious input. You are better off generating your own (safe) filenames, or at the very least using a hash of the filename.
* `encoding` - _string_ - The file's `'Content-Transfer-Encoding'` value.
* `mimeType` - _string_ - The file's `'Content-Type'` value.
**Note:** If you listen for this event, you should always consume the `stream` whether you care about its contents or not (you can simply do `stream.resume();` if you want to discard/skip the contents), otherwise the `'finish'`/`'close'` event will never fire on the busboy parser stream.
However, if you aren't accepting files, you can either simply not listen for the `'file'` event at all or set `limits.files` to `0`, and any/all files will be automatically skipped (these skipped files will still count towards any configured `limits.files` and `limits.parts` limits though).
**Note:** If a configured `limits.fileSize` limit was reached for a file, `stream` will both have a boolean property `truncated` set to `true` (best checked at the end of the stream) and emit a `'limit'` event to notify you when this happens.
* **field**(< _string_ >name, < _string_ >value, < _object_ >info) - Emitted for each new non-file field found. `name` contains the form field name. `value` contains the string value of the field. `info` contains the following properties:
* `nameTruncated` - _boolean_ - Whether `name` was truncated or not (due to a configured `limits.fieldNameSize` limit)
* `valueTruncated` - _boolean_ - Whether `value` was truncated or not (due to a configured `limits.fieldSize` limit)
* `encoding` - _string_ - The field's `'Content-Transfer-Encoding'` value.
* `mimeType` - _string_ - The field's `'Content-Type'` value.
* **partsLimit**() - Emitted when the configured `limits.parts` limit has been reached. No more `'file'` or `'field'` events will be emitted.
* **filesLimit**() - Emitted when the configured `limits.files` limit has been reached. No more `'file'` events will be emitted.
* **fieldsLimit**() - Emitted when the configured `limits.fields` limit has been reached. No more `'field'` events will be emitted.

# express-fileupload
Simple express middleware for uploading files.
[![npm](https://img.shields.io/npm/v/express-fileupload.svg)](https://www.npmjs.org/package/express-fileupload)
[![downloads per month](http://img.shields.io/npm/dm/express-fileupload.svg)](https://www.npmjs.org/package/express-fileupload)
[![CircleCI](https://circleci.com/gh/richardgirges/express-fileupload/tree/master.svg?style=svg)](https://circleci.com/gh/richardgirges/express-fileupload/tree/master)
[![Coverage Status](https://img.shields.io/coveralls/richardgirges/express-fileupload.svg)](https://coveralls.io/r/richardgirges/express-fileupload)
# Help us Improve express-fileupload
This package is still very much supported and maintained. But the more help the better. If you're interested any of the following:
* Ticket and PR triage
* Feature scoping and implementation
* Maintenance (upgrading packages, fixing security vulnerabilities, etc)
...please contact richardgirges '-at-' gmail.com
# Install
```bash
# With NPM
npm i express-fileupload
# With Yarn
yarn add express-fileupload
```
# Usage
When you upload a file, the file will be accessible from `req.files`.
Example:
* You're uploading a file called **car.jpg**
* Your input's name field is **foo**: `<input name="foo" type="file" />`
* In your express server request, you can access your uploaded file from `req.files.foo`:
```javascript
app.post('/upload', function(req, res) {
console.log(req.files.foo); // the uploaded file object
});
```
The **req.files.foo** object will contain the following:
* `req.files.foo.name`: "car.jpg"
* `req.files.foo.mv`: A function to move the file elsewhere on your server. Can take a callback or return a promise.
* `req.files.foo.mimetype`: The mimetype of your file
* `req.files.foo.data`: A buffer representation of your file, returns empty buffer in case useTempFiles option was set to true.
* `req.files.foo.tempFilePath`: A path to the temporary file in case useTempFiles option was set to true.
* `req.files.foo.truncated`: A boolean that represents if the file is over the size limit
* `req.files.foo.size`: Uploaded size in bytes
* `req.files.foo.md5`: MD5 checksum of the uploaded file
**Notes about breaking changes with MD5 handling:**
* Before 1.0.0, `md5` is an MD5 checksum of the uploaded file.
* From 1.0.0 until 1.1.1, `md5` is a function to compute an MD5 hash ([Read about it here.](https://github.com/richardgirges/express-fileupload/releases/tag/v1.0.0-alpha.1)).
* From 1.1.1 onward, `md5` is reverted back to MD5 checksum value and also added full MD5 support in case you are using temporary files.
### Examples
* [Example Project](https://github.com/richardgirges/express-fileupload/tree/master/example)
* [Basic File Upload](https://github.com/richardgirges/express-fileupload/tree/master/example#basic-file-upload)
* [Multi-File Upload](https://github.com/richardgirges/express-fileupload/tree/master/example#multi-file-upload)
### Using Busboy Options
Pass in Busboy options directly to the express-fileupload middleware. [Check out the Busboy documentation here](https://github.com/mscdex/busboy#api).
```javascript
app.use(fileUpload({
limits: { fileSize: 50 * 1024 * 1024 },
}));
```
### Using useTempFile Options
Use temp files instead of memory for managing the upload process.
```javascript
// Note that this option available for versions 1.0.0 and newer.
app.use(fileUpload({
useTempFiles : true,
tempFileDir : '/tmp/'
}));
```
### Using debug option
You can set `debug` option to `true` to see some logging about upload process.
In this case middleware uses `console.log` and adds `Express-file-upload` prefix for outputs.
It will show you whether the request is invalid and also common events triggered during upload.
That can be really useful for troubleshooting and ***we recommend attaching debug output to each issue on Github***.
***Output example:***
```
Express-file-upload: Temporary file path is /node/express-fileupload/test/temp/tmp-16-1570084843942
Express-file-upload: New upload started testFile->car.png, bytes:0
Express-file-upload: Uploading testFile->car.png, bytes:21232...
Express-file-upload: Uploading testFile->car.png, bytes:86768...
Express-file-upload: Upload timeout testFile->car.png, bytes:86768
Express-file-upload: Cleaning up temporary file /node/express-fileupload/test/temp/tmp-16-1570084843942...
```
***Description:***
* `Temporary file path is...` says that `useTempfiles` was set to true and also shows you temp file name and path.
* `New upload started testFile->car.png` says that new upload started with field `testFile` and file name `car.png`.
* `Uploading testFile->car.png, bytes:21232...` shows current progress for each new data chunk.
* `Upload timeout` means that no data came during `uploadTimeout`.
* `Cleaning up temporary file` Here finaly we see cleaning up of the temporary file because of upload timeout reached.
### Available Options
Pass in non-Busboy options directly to the middleware. These are express-fileupload specific options.
Option | Acceptable&nbsp;Values | Details
--- | --- | ---
createParentPath | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></ul> | Automatically creates the directory path specified in `.mv(filePathName)`
uriDecodeFileNames | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></ul> | Applies uri decoding to file names if set true.
safeFileNames | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></li><li>regex</li></ul> | Strips characters from the upload's filename. You can use custom regex to determine what to strip. If set to `true`, non-alphanumeric characters _except_ dashes and underscores will be stripped. This option is off by default.<br /><br />**Example #1 (strip slashes from file names):** `app.use(fileUpload({ safeFileNames: /\\/g }))`<br />**Example #2:** `app.use(fileUpload({ safeFileNames: true }))`
preserveExtension | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></li><li><code>*Number*</code></li></ul> | Preserves filename extension when using <code>safeFileNames</code> option. If set to <code>true</code>, will default to an extension length of 3. If set to <code>*Number*</code>, this will be the max allowable extension length. If an extension is smaller than the extension length, it remains untouched. If the extension is longer, it is shifted.<br /><br />**Example #1 (true):**<br /><code>app.use(fileUpload({ safeFileNames: true, preserveExtension: true }));</code><br />*myFileName.ext* --> *myFileName.ext*<br /><br />**Example #2 (max extension length 2, extension shifted):**<br /><code>app.use(fileUpload({ safeFileNames: true, preserveExtension: 2 }));</code><br />*myFileName.ext* --> *myFileNamee.xt*
abortOnLimit | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></ul> | Returns a HTTP 413 when the file is bigger than the size limit if true. Otherwise, it will add a <code>truncated = true</code> to the resulting file structure.
responseOnLimit | <ul><li><code>'File size limit has been reached'</code>&nbsp;**(default)**</li><li><code>*String*</code></ul> | Response which will be send to client if file size limit exceeded when abortOnLimit set to true.
limitHandler | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>function(req, res, next)</code></li></ul> | User defined limit handler which will be invoked if the file is bigger than configured limits.
useTempFiles | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></ul> | By default this module uploads files into RAM. Setting this option to True turns on using temporary files instead of utilising RAM. This avoids memory overflow issues when uploading large files or in case of uploading lots of files at same time.
tempFileDir | <ul><li><code>String</code>&nbsp;**(path)**</li></ul> | Path to store temporary files.<br />Used along with the <code>useTempFiles</code> option. By default this module uses 'tmp' folder in the current working directory.<br />You can use trailing slash, but it is not necessary.
parseNested | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></li></ul> | By default, req.body and req.files are flattened like this: <code>{'name': 'John', 'hobbies[0]': 'Cinema', 'hobbies[1]': 'Bike'}</code><br /><br/>When this option is enabled they are parsed in order to be nested like this: <code>{'name': 'John', 'hobbies': ['Cinema', 'Bike']}</code>
debug | <ul><li><code>false</code>&nbsp;**(default)**</li><li><code>true</code></ul> | Turn on/off upload process logging. Can be useful for troubleshooting.
uploadTimeout | <ul><li><code>60000</code>&nbsp;**(default)**</li><li><code>Integer</code></ul> | This defines how long to wait for data before aborting. Set to 0 if you want to turn off timeout checks.

# express-fileupload Examples
## Basic File Upload
**Your node.js code:**
```javascript
const express = require('express');
const fileUpload = require('express-fileupload');
const app = express();
// default options
app.use(fileUpload());
app.post('/upload', function(req, res) {
let sampleFile;
let uploadPath;
if (!req.files || Object.keys(req.files).length === 0) {
return res.status(400).send('No files were uploaded.');
}
// The name of the input field (i.e. "sampleFile") is used to retrieve the uploaded file
sampleFile = req.files.sampleFile;
uploadPath = __dirname + '/somewhere/on/your/server/' + sampleFile.name;
// Use the mv() method to place the file somewhere on your server
sampleFile.mv(uploadPath, function(err) {
if (err)
return res.status(500).send(err);
res.send('File uploaded!');
});
});
```
**Your HTML file upload form:**
```html
<html>
<body>
<form ref='uploadForm'
id='uploadForm'
action='http://localhost:8000/upload'
method='post'
encType="multipart/form-data">
<input type="file" name="sampleFile" />
<input type='submit' value='Upload!' />
</form>
</body>
</html>
```
## Multi-File Upload
express-fileupload supports multiple file uploads at the same time.
Let's say you have three files in your form, each of the inputs with the name `my_profile_pic`, `my_pet`, and `my_cover_photo`:
```html
<input type="file" name="my_profile_pic" />
<input type="file" name="my_pet" />
<input type="file" name="my_cover_photo" />
```
These uploaded files would be accessible like so:
```javascript
app.post('/upload', function(req, res) {
// Uploaded files:
console.log(req.files.my_profile_pic.name);
console.log(req.files.my_pet.name);
console.log(req.files.my_cover_photo.name);
});
```

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' }))
```

# raw-body
[![NPM Version][npm-image]][npm-url]
[![NPM Downloads][downloads-image]][downloads-url]
[![Node.js Version][node-version-image]][node-version-url]
[![Build status][github-actions-ci-image]][github-actions-ci-url]
[![Test coverage][coveralls-image]][coveralls-url]
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.
## 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 raw-body
```
### TypeScript
This module includes a [TypeScript](https://www.typescriptlang.org/)
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`:
```sh
$ npm install @types/node
```
## API
```js
var getRawBody = require('raw-body')
```
### getRawBody(stream, [options], [callback])
**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](https://www.npmjs.com/package/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](https://www.npmjs.org/package/iconv-lite#readme).
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, you may need to finish consuming the stream if
you want to keep the socket open for future requests. For streams
that use file descriptors, you should `stream.destroy()` or
`stream.close()` to prevent leaks.
## Errors
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 bytes
* `length` and `expected` - the expected length of the stream
* `received` - the received bytes
* `encoding` - the invalid encoding
* `status` and `statusCode` - the corresponding status code for the error
* `type` - the error type
### Types
The errors from this module have a `type` property which allows for the programmatic
determination of the type of error returned.
#### encoding.unsupported
This error will occur when the `encoding` option is specified, but the value does
not map to an encoding supported by the [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme)
module.
#### entity.too.large
This error will occur when the `limit` option is specified, but the stream has
an entity that is larger.
#### request.aborted
This error will occur when the request stream is aborted by the client before
reading the body has finished.
#### request.size.invalid
This error will occur when the `length` option is specified, but the stream has
emitted more bytes.
#### stream.encoding.set
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.
#### stream.not.readable
This error will occur when the given stream is not readable.
## Examples
### Simple Express example
```js
var contentType = require('content-type')
var express = require('express')
var getRawBody = require('raw-body')
var app = express()
app.use(function (req, res, next) {
getRawBody(req, {
length: req.headers['content-length'],
limit: '1mb',
encoding: contentType.parse(req).parameters.charset
}, function (err, string) {
if (err) return next(err)
req.text = string
next()
})
})
// now access req.text
```
### Simple Koa example
```js
var contentType = require('content-type')
var getRawBody = require('raw-body')
var koa = require('koa')
var app = koa()
app.use(function * (next) {
this.text = yield getRawBody(this.req, {
length: this.req.headers['content-length'],
limit: '1mb',
encoding: contentType.parse(this.req).parameters.charset
})
yield next
})
// now access this.text
```
### Using as a promise
To use this library as a promise, simply omit the `callback` and a promise is
returned, provided that a global `Promise` is defined.
```js
var getRawBody = require('raw-body')
var http = require('http')
var server = http.createServer(function (req, res) {
getRawBody(req)
.then(function (buf) {
res.statusCode = 200
res.end(buf.length + ' bytes submitted')
})
.catch(function (err) {
res.statusCode = 500
res.end(err.message)
})
})
server.listen(3000)
```
### Using with TypeScript
```ts
import * as getRawBody from 'raw-body';
import * as http from 'http';
const server = http.createServer((req, res) => {
getRawBody(req)
.then((buf) => {
res.statusCode = 200;
res.end(buf.length + ' bytes submitted');
})
.catch((err) => {
res.statusCode = err.statusCode;
res.end(err.message);
});
});
server.listen(3000);
```

Description
===========
streamsearch is a module for [node.js](http://nodejs.org/) that allows searching a stream using the Boyer-Moore-Horspool algorithm.
This module is based heavily on the Streaming Boyer-Moore-Horspool C++ implementation by Hongli Lai [here](https://github.com/FooBarWidget/boyer-moore-horspool).
Requirements
============
* [node.js](http://nodejs.org/) -- v10.0.0 or newer
Installation
============
npm install streamsearch
Example
=======
```js
const { inspect } = require('util');
const StreamSearch = require('streamsearch');
const needle = Buffer.from('\r\n');
const ss = new StreamSearch(needle, (isMatch, data, start, end) => {
if (data)
console.log('data: ' + inspect(data.toString('latin1', start, end)));
if (isMatch)
console.log('match!');
});
const chunks = [
'foo',
' bar',
'\r',
'\n',
'baz, hello\r',
'\n world.',
'\r\n Node.JS rules!!\r\n\r\n',
];
for (const chunk of chunks)
ss.push(Buffer.from(chunk));
// output:
//
// data: 'foo'
// data: ' bar'
// match!
// data: 'baz, hello'
// match!
// data: ' world.'
// match!
// data: ' Node.JS rules!!'
// match!
// data: ''
// match!
```
API
===
Properties
----------
* **maxMatches** - < _integer_ > - The maximum number of matches. Defaults to `Infinity`.
* **matches** - < _integer_ > - The current match count.
Functions
---------
* **(constructor)**(< _mixed_ >needle, < _function_ >callback) - Creates and returns a new instance for searching for a _Buffer_ or _string_ `needle`. `callback` is called any time there is non-matching data and/or there is a needle match. `callback` will be called with the following arguments:
1. `isMatch` - _boolean_ - Indicates whether a match has been found
2. `data` - _mixed_ - If set, this contains data that did not match the needle.
3. `start` - _integer_ - The index in `data` where the non-matching data begins (inclusive).
4. `end` - _integer_ - The index in `data` where the non-matching data ends (exclusive).
5. `isSafeData` - _boolean_ - Indicates if it is safe to store a reference to `data` (e.g. as-is or via `data.slice()`) or not, as in some cases `data` may point to a Buffer whose contents change over time.
* **destroy**() - _(void)_ - Emits any last remaining unmatched data that may still be buffered and then resets internal state.
* **push**(< _Buffer_ >chunk) - _integer_ - Processes `chunk`, searching for a match. The return value is the last processed index in `chunk` + 1.
* **reset**() - _(void)_ - Resets internal state. Useful for when you wish to start searching a new/different stream for example.
