+# `append-field`
+
+A [W3C HTML JSON forms spec](http://www.w3.org/TR/html-json-forms/) compliant
+field appender (for lack of a better name). Useful for people implementing
+`application/x-www-form-urlencoded` and `multipart/form-data` parsers.
+
+It works best on objects created with `Object.create(null)`. Otherwise it might
+conflict with variables from the prototype (e.g. `hasOwnProperty`).
+
+## Installation
+
+```sh
+npm install --save append-field
+```
+
+## Usage
+
+```javascript
+var appendField = require('append-field')
+var obj = Object.create(null)
+
+appendField(obj, 'pets[0][species]', 'Dahut')
+appendField(obj, 'pets[0][name]', 'Hypatia')
+appendField(obj, 'pets[1][species]', 'Felis Stultus')
+appendField(obj, 'pets[1][name]', 'Billie')
+
+console.log(obj)
+```
+
+```text
+{ pets:
+   [ { species: 'Dahut', name: 'Hypatia' },
+     { species: 'Felis Stultus', name: 'Billie' } ] }
+```
+
+## API
+
+### `appendField(store, key, value)`
+
+Adds the field named `key` with the value `value` to the object `store`.

+## Installation
+
+```sh
+npm install --save buffer-from
+```
+
+## Usage
+
+```js
+const bufferFrom = require('buffer-from')
+
+console.log(bufferFrom([1, 2, 3, 4]))
+//=> <Buffer 01 02 03 04>
+
+const arr = new Uint8Array([1, 2, 3, 4])

+//=> <Buffer 02 03>
+
+console.log(bufferFrom('test', 'utf8'))
+//=> <Buffer 74 65 73 74>
+
+const buf = bufferFrom('test')
+console.log(bufferFrom(buf))
+//=> <Buffer 74 65 73 74>
+```
+
+## API
+
+### bufferFrom(array)
+
+- `array` &lt;Array&gt;
+
+Allocates a new `Buffer` using an `array` of octets.
+
+### bufferFrom(arrayBuffer[, byteOffset[, length]])
+
+- `arrayBuffer` &lt;ArrayBuffer&gt; The `.buffer` property of a TypedArray or ArrayBuffer
+- `byteOffset` &lt;Integer&gt; Where to start copying from `arrayBuffer`. **Default:** `0`
+- `length` &lt;Integer&gt; How many bytes to copy from `arrayBuffer`. **Default:** `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a TypedArray instance, the
+newly created `Buffer` will share the same allocated memory as the TypedArray.
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+### bufferFrom(buffer)
+
+- `buffer` &lt;Buffer&gt; An existing `Buffer` to copy data from
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+### bufferFrom(string[, encoding])
+
+- `string` &lt;String&gt; A string to encode.
+- `encoding` &lt;String&gt; The encoding of `string`. **Default:** `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `string`. If
+provided, the `encoding` parameter identifies the character encoding of
+`string`.

+<a href='https://pledgie.com/campaigns/28774'><img alt='Click here to support busboy' src='https://pledgie.com/campaigns/28774.png?skin_name=chrome' border='0'></a>
+
+
+Requirements
+============
+
+* [node.js](http://nodejs.org/) -- v0.8.0 or newer
+
+
+Install
+=======
+
+    npm install busboy
+
+
+Examples
+========
+
+* Parsing (multipart) with default options:
+
+```javascript
+var http = require('http'),
+    inspect = require('util').inspect;
+
+var Busboy = require('busboy');
+
+http.createServer(function(req, res) {
+  if (req.method === 'POST') {
+    var busboy = new Busboy({ headers: req.headers });
+    busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
+      console.log('File [' + fieldname + ']: filename: ' + filename + ', encoding: ' + encoding + ', mimetype: ' + mimetype);
+      file.on('data', function(data) {
+        console.log('File [' + fieldname + '] got ' + data.length + ' bytes');
+      });
+      file.on('end', function() {
+        console.log('File [' + fieldname + '] Finished');
+      });
+    });
+    busboy.on('field', function(fieldname, val, fieldnameTruncated, valTruncated, encoding, mimetype) {
+      console.log('Field [' + fieldname + ']: value: ' + inspect(val));
+    });
+    busboy.on('finish', function() {
+      console.log('Done parsing form!');
+      res.writeHead(303, { Connection: 'close', Location: '/' });
+      res.end();
+    });
+    req.pipe(busboy);
+  } 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="text" name="textfield"><br />\
+                <input type="file" name="filefield"><br />\
+                <input type="submit">\
+              </form>\
+            </body></html>');
+  }
+}).listen(8000, function() {
+  console.log('Listening for requests');
+});
+
+// Example output, using http://nodejs.org/images/ryan-speaker.jpg as the file:
+//
+// Listening for requests
+// File [filefield]: filename: ryan-speaker.jpg, encoding: binary
+// File [filefield] got 11971 bytes
+// Field [textfield]: value: 'testing! :-)'
+// File [filefield] Finished
+// Done parsing form!
+```
+
+* Save all incoming files to disk:
+
+```javascript
+var http = require('http'),
+    path = require('path'),
+    os = require('os'),
+    fs = require('fs');
+
+var Busboy = require('busboy');
+
+http.createServer(function(req, res) {
+  if (req.method === 'POST') {
+    var busboy = new Busboy({ headers: req.headers });
+    busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
+      var saveTo = path.join(os.tmpDir(), path.basename(fieldname));
+      file.pipe(fs.createWriteStream(saveTo));
+    });
+    busboy.on('finish', function() {
+      res.writeHead(200, { 'Connection': 'close' });
+      res.end("That's all folks!");
+    });
+    return req.pipe(busboy);
+  }
+  res.writeHead(404);
+  res.end();
+}).listen(8000, function() {
+  console.log('Listening for requests');
+});
+```
+
+* Parsing (urlencoded) with default options:
+
+```javascript
+var http = require('http'),
+    inspect = require('util').inspect;
+
+var Busboy = require('busboy');
+
+http.createServer(function(req, res) {

+      file.on('data', function(data) {
+        console.log('File [' + fieldname + '] got ' + data.length + ' bytes');
+      });
+      file.on('end', function() {
+        console.log('File [' + fieldname + '] Finished');
+      });
+    });
+    busboy.on('field', function(fieldname, val, fieldnameTruncated, valTruncated) {
+      console.log('Field [' + fieldname + ']: value: ' + inspect(val));
+    });

+
+API
+===
+
+_Busboy_ is a _Writable_ stream
+
+Busboy (special) events
+-----------------------
+
+* **file**(< _string_ >fieldname, < _ReadableStream_ >stream, < _string_ >filename, < _string_ >transferEncoding, < _string_ >mimeType) - Emitted for each new file form field found. `transferEncoding` contains the 'Content-Transfer-Encoding' value for the file stream. `mimeType` contains the 'Content-Type' value for the file stream.
+    * Note: if you listen for this event, you should always handle the `stream` no matter if you care about the file contents or not (e.g. you can simply just do `stream.resume();` if you want to discard the contents), otherwise the 'finish' event will never fire on the Busboy instance. However, if you don't care about **any** incoming files, you can simply not listen for the 'file' event at all and any/all files will be automatically and safely discarded (these discarded files do still count towards `files` and `parts` limits).
+    * If a configured file size limit was reached, `stream` will both have a boolean property `truncated` (best checked at the end of the stream) and emit a 'limit' event to notify you when this happens.
+
+* **field**(< _string_ >fieldname, < _string_ >value, < _boolean_ >fieldnameTruncated, < _boolean_ >valueTruncated, < _string_ >transferEncoding, < _string_ >mimeType) - Emitted for each new non-file field found.
+
+* **partsLimit**() - Emitted when specified `parts` limit has been reached. No more 'file' or 'field' events will be emitted.
+
+* **filesLimit**() - Emitted when specified `files` limit has been reached. No more 'file' events will be emitted.
+
+* **fieldsLimit**() - Emitted when specified `fields` limit has been reached. No more 'field' events will be emitted.
+
+
+Busboy methods
+--------------
+
+* **(constructor)**(< _object_ >config) - Creates and returns a new Busboy instance.
+
+    * The constructor takes the following valid `config` settings:
+
+        * **headers** - _object_ - These are the HTTP headers of the incoming request, which are used by individual parsers.
+
+        * **highWaterMark** - _integer_ - highWaterMark to use for this Busboy instance (Default: WritableStream default).
+
+        * **fileHwm** - _integer_ - highWaterMark to use for file streams (Default: ReadableStream default).
+
+        * **defCharset** - _string_ - Default character set to use when one isn't defined (Default: 'utf8').
+
+        * **preservePath** - _boolean_ - If paths in the multipart 'filename' field 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 bytes).
+
+            * **fieldSize** - _integer_ - Max field value size (in bytes) (Default: 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).
+
+    * The constructor can throw errors:
+
+        * **Unsupported content type: $type** - The `Content-Type` isn't one Busboy can parse.
+
+        * **Missing Content-Type** - The provided headers don't include `Content-Type` at all.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+
+
+```bash
+npm install --save string_decoder
+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+# concat-stream
+
+Writable stream that concatenates all the data from a stream and calls a callback with the result. Use this when you want to collect all the data from a stream into a single buffer.
+
+[![Build Status](https://travis-ci.org/maxogden/concat-stream.svg?branch=master)](https://travis-ci.org/maxogden/concat-stream)
+
+[![NPM](https://nodei.co/npm/concat-stream.png)](https://nodei.co/npm/concat-stream/)
+
+### description
+
+Streams emit many buffers. If you want to collect all of the buffers, and when the stream ends concatenate all of the buffers together and receive a single buffer then this is the module for you.
+
+Only use this if you know you can fit all of the output of your stream into a single Buffer (e.g. in RAM).
+
+There are also `objectMode` streams that emit things other than Buffers, and you can concatenate these too. See below for details.
+
+## Related
+
+`concat-stream` is part of the [mississippi stream utility collection](https://github.com/maxogden/mississippi) which includes more useful stream modules similar to this one.
+
+### examples
+
+#### Buffers
+
+```js
+var fs = require('fs')
+var concat = require('concat-stream')
+
+var readStream = fs.createReadStream('cat.png')
+var concatStream = concat(gotPicture)
+
+readStream.on('error', handleError)
+readStream.pipe(concatStream)
+
+function gotPicture(imageBuffer) {
+  // imageBuffer is all of `cat.png` as a node.js Buffer
+}
+
+function handleError(err) {
+  // handle your error appropriately here, e.g.:
+  console.error(err) // print the error to STDERR
+  process.exit(1) // exit program with non-zero exit code
+}
+
+```
+
+#### Arrays
+
+```js
+var write = concat(function(data) {})
+write.write([1,2,3])
+write.write([4,5,6])
+write.end()
+// data will be [1,2,3,4,5,6] in the above callback
+```
+
+#### Uint8Arrays
+
+```js
+var write = concat(function(data) {})
+var a = new Uint8Array(3)
+a[0] = 97; a[1] = 98; a[2] = 99
+write.write(a)
+write.write('!')
+write.end(Buffer.from('!!1'))
+```
+
+See `test/` for more examples
+
+# methods
+
+```js
+var concat = require('concat-stream')
+```
+
+## var writable = concat(opts={}, cb)
+
+Return a `writable` stream that will fire `cb(data)` with all of the data that
+was written to the stream. Data can be written to `writable` as strings,
+Buffers, arrays of byte integers, and Uint8Arrays. 
+
+By default `concat-stream` will give you back the same data type as the type of the first buffer written to the stream. Use `opts.encoding` to set what format `data` should be returned as, e.g. if you if you don't want to rely on the built-in type checking or for some other reason.
+
+* `string` - get a string
+* `buffer` - get back a Buffer
+* `array` - get an array of byte integers
+* `uint8array`, `u8`, `uint8` - get back a Uint8Array
+* `object`, get back an array of Objects
+
+If you don't specify an encoding, and the types can't be inferred (e.g. you write things that aren't in the list above), it will try to convert concat them into a `Buffer`.
+
+If nothing is written to `writable` then `data` will be an empty array `[]`.
+
+# error handling
+
+`concat-stream` does not handle errors for you, so you must handle errors on whatever streams you pipe into `concat-stream`. This is a general rule when programming with node.js streams: always handle errors on each and every stream. Since `concat-stream` is not itself a stream it does not emit errors.
+
+We recommend using [`end-of-stream`](https://npmjs.org/end-of-stream) or [`pump`](https://npmjs.org/pump) for writing error tolerant stream code.

+Description
+===========
+
+A very fast streaming multipart parser for node.js.
+
+Benchmarks can be found [here](https://github.com/mscdex/dicer/wiki/Benchmarks).
+
+
+Requirements
+============
+
+* [node.js](http://nodejs.org/) -- v0.8.0 or newer
+
+
+Install
+============
+
+    npm install dicer
+
+
+Examples
+========
+
+* Parse an HTTP form upload
+
+```javascript
+var inspect = require('util').inspect,
+    http = require('http');
+
+var Dicer = require('dicer');
+
+    // quick and dirty way to parse multipart boundary
+var RE_BOUNDARY = /^multipart\/.+?(?:; boundary=(?:(?:"(.+)")|(?:([^\s]+))))$/i,
+    HTML = new Buffer('<html><head></head><body>\
+                       <form method="POST" enctype="multipart/form-data">\
+                         <input type="text" name="textfield"><br />\
+                         <input type="file" name="filefield"><br />\
+                         <input type="submit">\
+                       </form>\
+                       </body></html>'),
+    PORT = 8080;
+
+http.createServer(function(req, res) {
+  var m;
+  if (req.method === 'POST'
+      && req.headers['content-type']
+      && (m = RE_BOUNDARY.exec(req.headers['content-type']))) {
+    var d = new Dicer({ boundary: m[1] || m[2] });
+
+    d.on('part', function(p) {
+      console.log('New part!');
+      p.on('header', function(header) {
+        for (var h in header) {
+          console.log('Part header: k: ' + inspect(h)
+                      + ', v: ' + inspect(header[h]));
+        }
+      });
+      p.on('data', function(data) {
+        console.log('Part data: ' + inspect(data.toString()));
+      });
+      p.on('end', function() {
+        console.log('End of part\n');
+      });
+    });
+    d.on('finish', function() {
+      console.log('End of parts');
+      res.writeHead(200);
+      res.end('Form submission successful!');
+    });
+    req.pipe(d);
+  } else if (req.method === 'GET' && req.url === '/') {
+    res.writeHead(200);
+    res.end(HTML);
+  } else {
+    res.writeHead(404);
+    res.end();
+  }
+}).listen(PORT, function() {
+  console.log('Listening for requests on port ' + PORT);
+});

+
+
+API
+===
+
+_Dicer_ is a _WritableStream_
+
+Dicer (special) events
+----------------------
+
+* **finish**() - Emitted when all parts have been parsed and the Dicer instance has been ended.
+
+* **part**(< _PartStream_ >stream) - Emitted when a new part has been found.
+
+* **preamble**(< _PartStream_ >stream) - Emitted for preamble if you should happen to need it (can usually be ignored).
+
+* **trailer**(< _Buffer_ >data) - Emitted when trailing data was found after the terminating boundary (as with the preamble, this can usually be ignored too).
+
+
+Dicer methods
+-------------
+
+* **(constructor)**(< _object_ >config) - Creates and returns a new Dicer instance with the following valid `config` settings:
+
+    * **boundary** - _string_ - This is the boundary used to detect the beginning of a new part.
+
+    * **headerFirst** - _boolean_ - If true, preamble header parsing will be performed first.
+
+    * **maxHeaderPairs** - _integer_ - The maximum number of header key=>value pairs to parse **Default:** 2000 (same as node's http).
+
+* **setBoundary**(< _string_ >boundary) - _(void)_ - Sets the boundary to use for parsing and performs some initialization needed for parsing. You should only need to use this if you set `headerFirst` to true in the constructor and are parsing the boundary from the preamble header.
+
+
+
+_PartStream_ is a _ReadableStream_
+
+PartStream (special) events
+---------------------------
+
+* **header**(< _object_ >header) - An object containing the header for this particular part. Each property value is an _array_ of one or more string values.

+## Moderation Policy
+
+The [Node.js Moderation Policy] applies to this WG.
+
+## Code of Conduct
+
+The [Node.js Code of Conduct][] applies to this WG.
+
+[Node.js Code of Conduct]:
+https://github.com/nodejs/node/blob/master/CODE_OF_CONDUCT.md
+[Node.js Moderation Policy]:
+https://github.com/nodejs/TSC/blob/master/Moderation-Policy.md

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+[![Sauce Test Status](https://saucelabs.com/browser-matrix/readabe-stream.svg)](https://saucelabs.com/u/readabe-stream)
+
+```bash
+npm install --save readable-stream
+```
+
+This package is a mirror of the streams implementations in Node.js.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v10.19.0/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+## Version 3.x.x
+
+v3.x.x of `readable-stream` is a cut from Node 10. This version supports Node 6, 8, and 10, as well as evergreen browsers, IE 11 and latest Safari. The breaking changes introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/) and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
+
+1. Error codes: https://github.com/nodejs/node/pull/13310,
+   https://github.com/nodejs/node/pull/13291,
+   https://github.com/nodejs/node/pull/16589,
+   https://github.com/nodejs/node/pull/15042,
+   https://github.com/nodejs/node/pull/15665,
+   https://github.com/nodejs/readable-stream/pull/344
+2. 'readable' have precedence over flowing
+   https://github.com/nodejs/node/pull/18994
+3. make virtual methods errors consistent
+   https://github.com/nodejs/node/pull/18813
+4. updated streams error handling
+   https://github.com/nodejs/node/pull/18438
+5. writable.end should return this.
+   https://github.com/nodejs/node/pull/18780
+6. readable continues to read when push('')
+   https://github.com/nodejs/node/pull/18211
+7. add custom inspect to BufferList
+   https://github.com/nodejs/node/pull/17907
+8. always defer 'readable' with nextTick
+   https://github.com/nodejs/node/pull/17979
+
+## Version 2.x.x
+v2.x.x of `readable-stream` is a cut of the stream module from Node 8 (there have been no semver-major changes from Node 4 to 8). This version supports all Node.js versions from 0.8, as well as evergreen browsers and IE 10 & 11.

+
+# Usage
+
+You can swap your `require('stream')` with `require('readable-stream')`
+without any changes, if you are just using one of the main classes and
+functions.
+
+```js
+const {
+  Readable,
+  Writable,
+  Transform,
+  Duplex,
+  pipeline,
+  finished
+} = require('readable-stream')
+````
+
+Note that `require('stream')` will return `Stream`, while
+`require('readable-stream')` will return `Readable`. We discourage using
+whatever is exported directly, but rather use one of the properties as
+shown in the example above.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+***Node-core v8.9.4 string_decoder for userland***
+
+
+[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash

+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.log(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# security
+
+Previous versions had a prototype pollution bug that could cause privilege
+escalation in some circumstances when handling untrusted user input.
+
+Please use version 1.2.3 or later: https://snyk.io/vuln/SNYK-JS-MINIMIST-559764
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+
+  ```
+  > require('./')('one two three -- four five --six'.split(' '), { '--': true })
+  { _: [ 'one', 'two', 'three' ],
+    '--': [ 'four', 'five', '--six' ] }
+  ```
+
+  Note that with `opts['--']` set, parsing for arguments still stops after the
+  `--`.
+
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.

+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:

+# Multer [![Build Status](https://travis-ci.org/expressjs/multer.svg?branch=master)](https://travis-ci.org/expressjs/multer) [![NPM version](https://badge.fury.io/js/multer.svg)](https://badge.fury.io/js/multer) [![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg?style=flat)](https://github.com/feross/standard)
+
+Multer is a node.js middleware for handling `multipart/form-data`, which is primarily used for uploading files. It is written
+on top of [busboy](https://github.com/mscdex/busboy) for maximum efficiency.
+
+**NOTE**: Multer will not process any form which is not multipart (`multipart/form-data`).
+
+## Translations 
+
+This README is also available in other languages:
+
+- [简体中文](https://github.com/expressjs/multer/blob/master/doc/README-zh-cn.md) (Chinese)
+- [한국어](https://github.com/expressjs/multer/blob/master/doc/README-ko.md) (Korean)
+- [Русский язык](https://github.com/expressjs/multer/blob/master/doc/README-ru.md) (Russian)
+
+## Installation
+
+```sh
+$ npm install --save multer
+```
+
+## Usage
+
+Multer adds a `body` object and a `file` or `files` object to the `request` object. The `body` object contains the values of the text fields of the form, the `file` or `files` object contains the files uploaded via the form.
+
+Basic usage example:
+
+Don't forget the `enctype="multipart/form-data"` in your form.
+
+```html
+<form action="/profile" method="post" enctype="multipart/form-data">
+  <input type="file" name="avatar" />
+</form>
+```
+
+```javascript
+var express = require('express')
+var multer  = require('multer')
+var upload = multer({ dest: 'uploads/' })
+
+var app = express()
+
+app.post('/profile', upload.single('avatar'), function (req, res, next) {
+  // req.file is the `avatar` file
+  // req.body will hold the text fields, if there were any
+})
+
+app.post('/photos/upload', upload.array('photos', 12), function (req, res, next) {
+  // req.files is array of `photos` files
+  // req.body will contain the text fields, if there were any
+})
+
+var cpUpload = upload.fields([{ name: 'avatar', maxCount: 1 }, { name: 'gallery', maxCount: 8 }])
+app.post('/cool-profile', cpUpload, function (req, res, next) {
+  // req.files is an object (String -> Array) where fieldname is the key, and the value is array of files
+  //
+  // e.g.
+  //  req.files['avatar'][0] -> File
+  //  req.files['gallery'] -> Array
+  //
+  // req.body will contain the text fields, if there were any
+})
+```
+
+In case you need to handle a text-only multipart form, you should use the `.none()` method:
+
+```javascript
+var express = require('express')
+var app = express()
+var multer  = require('multer')
+var upload = multer()

+## API
+
+### File information
+
+Each file contains the following information:
+
+Key | Description | Note
+--- | --- | ---
+`fieldname` | Field name specified in the form |
+`originalname` | Name of the file on the user's computer |
+`encoding` | Encoding type of the file |
+`mimetype` | Mime type of the file |
+`size` | Size of the file in bytes |
+`destination` | The folder to which the file has been saved | `DiskStorage`
+`filename` | The name of the file within the `destination` | `DiskStorage`
+`path` | The full path to the uploaded file | `DiskStorage`
+`buffer` | A `Buffer` of the entire file | `MemoryStorage`
+
+### `multer(opts)`
+
+Multer accepts an options object, the most basic of which is the `dest`
+property, which tells Multer where to upload the files. In case you omit the
+options object, the files will be kept in memory and never written to disk.
+
+By default, Multer will rename the files so as to avoid naming conflicts. The
+renaming function can be customized according to your needs.
+
+The following are the options that can be passed to Multer.
+
+Key | Description
+--- | ---
+`dest` or `storage` | Where to store the files
+`fileFilter` | Function to control which files are accepted
+`limits` | Limits of the uploaded data
+`preservePath` | Keep the full path of files instead of just the base name
+
+In an average web app, only `dest` might be required, and configured as shown in
+the following example.
+
+```javascript
+var upload = multer({ dest: 'uploads/' })
+```
+
+If you want more control over your uploads, you'll want to use the `storage`
+option instead of `dest`. Multer ships with storage engines `DiskStorage`
+and `MemoryStorage`; More engines are available from third parties.
+
+#### `.single(fieldname)`
+
+Accept a single file with the name `fieldname`. The single file will be stored
+in `req.file`.
+
+#### `.array(fieldname[, maxCount])`
+
+Accept an array of files, all with the name `fieldname`. Optionally error out if
+more than `maxCount` files are uploaded. The array of files will be stored in
+`req.files`.
+
+#### `.fields(fields)`
+
+Accept a mix of files, specified by `fields`. An object with arrays of files
+will be stored in `req.files`.
+
+`fields` should be an array of objects with `name` and optionally a `maxCount`.
+Example:
+
+```javascript
+[
+  { name: 'avatar', maxCount: 1 },
+  { name: 'gallery', maxCount: 8 }
+]
+```
+
+#### `.none()`
+
+Accept only text fields. If any file upload is made, error with code
+"LIMIT\_UNEXPECTED\_FILE" will be issued.
+
+#### `.any()`
+
+Accepts all files that comes over the wire. An array of files will be stored in
+`req.files`.
+
+**WARNING:** Make sure that you always handle the files that a user uploads.
+Never add multer as a global middleware since a malicious user could upload
+files to a route that you didn't anticipate. Only use this function on routes
+where you are handling the uploaded files.
+
+### `storage`
+
+#### `DiskStorage`
+
+The disk storage engine gives you full control on storing files to disk.
+
+```javascript
+var storage = multer.diskStorage({
+  destination: function (req, file, cb) {
+    cb(null, '/tmp/my-uploads')
+  },
+  filename: function (req, file, cb) {
+    cb(null, file.fieldname + '-' + Date.now())
+  }
+})
+
+var upload = multer({ storage: storage })
+```
+
+There are two options available, `destination` and `filename`. They are both
+functions that determine where the file should be stored.
+
+`destination` is used to determine within which folder the uploaded files should
+be stored. This can also be given as a `string` (e.g. `'/tmp/uploads'`). If no
+`destination` is given, the operating system's default directory for temporary
+files is used.
+
+**Note:** You are responsible for creating the directory when providing
+`destination` as a function. When passing a string, multer will make sure that
+the directory is created for you.
+
+`filename` is used to determine what the file should be named inside the folder.
+If no `filename` is given, each file will be given a random name that doesn't
+include any file extension.
+
+**Note:** Multer will not append any file extension for you, your function
+should return a filename complete with an file extension.
+
+Each function gets passed both the request (`req`) and some information about
+the file (`file`) to aid with the decision.
+
+Note that `req.body` might not have been fully populated yet. It depends on the
+order that the client transmits fields and files to the server.
+
+#### `MemoryStorage`
+
+The memory storage engine stores the files in memory as `Buffer` objects. It
+doesn't have any options.
+
+```javascript
+var storage = multer.memoryStorage()
+var upload = multer({ storage: storage })
+```
+
+When using memory storage, the file info will contain a field called
+`buffer` that contains the entire file.
+
+**WARNING**: Uploading very large files, or relatively small files in large
+numbers very quickly, can cause your application to run out of memory when
+memory storage is used.
+
+### `limits`
+
+An object specifying the size limits of the following optional properties. Multer passes this object into busboy directly, and the details of the properties can be found on [busboy's page](https://github.com/mscdex/busboy#busboy-methods).
+
+The following integer values are available:
+
+Key | Description | Default
+--- | --- | ---
+`fieldNameSize` | Max field name size | 100 bytes
+`fieldSize` | Max field value size (in bytes) | 1MB
+`fields` | Max number of non-file fields | Infinity
+`fileSize` | For multipart forms, the max file size (in bytes) | Infinity
+`files` | For multipart forms, the max number of file fields | Infinity
+`parts` | For multipart forms, the max number of parts (fields + files) | Infinity
+`headerPairs` | For multipart forms, the max number of header key=>value pairs to parse | 2000
+
+Specifying the limits can help protect your site against denial of service (DoS) attacks.
+
+### `fileFilter`
+
+Set this to a function to control which files should be uploaded and which
+should be skipped. The function should look like this:
+
+```javascript
+function fileFilter (req, file, cb) {
+
+  // The function should call `cb` with a boolean
+  // to indicate if the file should be accepted
+
+  // To reject this file pass `false`, like so:
+  cb(null, false)
+
+  // To accept the file pass `true`, like so:
+  cb(null, true)
+
+  // You can always pass an error if something goes wrong:
+  cb(new Error('I don\'t have a clue!'))
+
+}
+```
+
+## Error handling
+
+When encountering an error, Multer will delegate the error to Express. You can
+display a nice error page using [the standard express way](http://expressjs.com/guide/error-handling.html).
+
+If you want to catch errors specifically from Multer, you can call the
+middleware function by yourself. Also, if you want to catch only [the Multer errors](https://github.com/expressjs/multer/blob/master/lib/multer-error.js), you can use the `MulterError` class that is attached to the `multer` object itself (e.g. `err instanceof multer.MulterError`).
+
+```javascript
+var multer = require('multer')
+var upload = multer().single('avatar')
+
+app.post('/profile', function (req, res) {
+  upload(req, res, function (err) {
+    if (err instanceof multer.MulterError) {
+      // A Multer error occurred when uploading.
+    } else if (err) {
+      // An unknown error occurred when uploading.
+    }
+
+    // Everything went fine.
+  })
+})
+```
+

+
+> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
+
+
+## Use the built-in
+
+Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
+support `Object.assign()` :tada:. If you target only those environments, then by all
+means, use `Object.assign()` instead of this package.
+
+
+## Install
+
+```
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+const objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});
+//=> {foo: 0, bar: 1, baz: 2}
+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

-This package is a mirror of the streams implementations in Node.js.
-
-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v10.19.0/docs/api/stream.html).
-
-If you want to guarantee a stable streams base, regardless of what version of
-Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
-
-As of version 2.0.0 **readable-stream** uses semantic versioning.
-
-## Version 3.x.x
-
-v3.x.x of `readable-stream` is a cut from Node 10. This version supports Node 6, 8, and 10, as well as evergreen browsers, IE 11 and latest Safari. The breaking changes introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/) and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
-
-1. Error codes: https://github.com/nodejs/node/pull/13310,
-   https://github.com/nodejs/node/pull/13291,
-   https://github.com/nodejs/node/pull/16589,
-   https://github.com/nodejs/node/pull/15042,
-   https://github.com/nodejs/node/pull/15665,
-   https://github.com/nodejs/readable-stream/pull/344
-2. 'readable' have precedence over flowing
-   https://github.com/nodejs/node/pull/18994
-3. make virtual methods errors consistent
-   https://github.com/nodejs/node/pull/18813
-4. updated streams error handling
-   https://github.com/nodejs/node/pull/18438
-5. writable.end should return this.
-   https://github.com/nodejs/node/pull/18780
-6. readable continues to read when push('')
-   https://github.com/nodejs/node/pull/18211
-7. add custom inspect to BufferList
-   https://github.com/nodejs/node/pull/17907
-8. always defer 'readable' with nextTick
-   https://github.com/nodejs/node/pull/17979
-
-## Version 2.x.x
-v2.x.x of `readable-stream` is a cut of the stream module from Node 8 (there have been no semver-major changes from Node 4 to 8). This version supports all Node.js versions from 0.8, as well as evergreen browsers and IE 10 & 11.

-
-# Usage
-
-You can swap your `require('stream')` with `require('readable-stream')`
-without any changes, if you are just using one of the main classes and
-functions.
-
-```js
-const {
-  Readable,
-  Writable,
-  Transform,
-  Duplex,
-  pipeline,
-  finished
-} = require('readable-stream')
-````
-
-Note that `require('stream')` will return `Stream`, while
-`require('readable-stream')` will return `Readable`. We discourage using
-whatever is exported directly, but rather use one of the properties as
-shown in the example above.
-
-# Streams Working Group
+[![NPM](https://nodei.co/npm-dl/readable-stream.png&months=6&height=3)](https://nodei.co/npm/readable-stream/)
 
-`readable-stream` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
 
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
 
-<a name="members"></a>
-## Team Members
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.

+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+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/) -- v0.8.0 or newer
+
+
+Installation
+============
+
+    npm install streamsearch
+
+Example
+=======
+
+```javascript
+  var StreamSearch = require('streamsearch'),
+      inspect = require('util').inspect;
+
+  var needle = new Buffer([13, 10]), // CRLF
+      s = new StreamSearch(needle),
+      chunks = [
+        new Buffer('foo'),
+        new Buffer(' bar'),
+        new Buffer('\r'),
+        new Buffer('\n'),
+        new Buffer('baz, hello\r'),
+        new Buffer('\n world.'),
+        new Buffer('\r\n Node.JS rules!!\r\n\r\n')
+      ];
+  s.on('info', function(isMatch, data, start, end) {
+    if (data)
+      console.log('data: ' + inspect(data.toString('ascii', start, end)));
+    if (isMatch)
+      console.log('match!');
+  });
+  for (var i = 0, len = chunks.length; i < len; ++i)
+    s.push(chunks[i]);
+
+  // output:
+  //
+  // data: 'foo'
+  // data: ' bar'
+  // match!
+  // data: 'baz, hello'
+  // match!
+  // data: ' world.'
+  // match!
+  // data: ' Node.JS rules!!'
+  // match!
+  // data: ''
+  // match!
+```
+
+
+API
+===
+
+Events
+------
+
+* **info**(< _boolean_ >isMatch[, < _Buffer_ >chunk, < _integer_ >start, < _integer_ >end]) - A match _may_ or _may not_ have been made. In either case, a preceding `chunk` of data _may_ be available that did not match the needle. Data (if available) is in `chunk` between `start` (inclusive) and `end` (exclusive).
+
+
+Properties
+----------
+
+* **maxMatches** - < _integer_ > - The maximum number of matches. Defaults to Infinity.
+
+* **matches** - < _integer_ > - The current match count.
+
+
+Functions
+---------
+
+* **(constructor)**(< _mixed_ >needle) - Creates and returns a new instance for searching for a _Buffer_ or _string_ `needle`.
+
+* **push**(< _Buffer_ >chunk) - _integer_ - Processes `chunk`. 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.

+Extend like a boss
+
+xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
+
+## Examples
+
+```js
+var extend = require("xtend")
+
+// extend returns a new object. Does not mutate arguments
+var combination = extend({
+    a: "a",
+    b: "c"
+}, {
+    b: "b"
+})
+// { a: "a", b: "b" }
+```
