+# duplexify
+
+Turn a writeable and readable stream into a single streams2 duplex stream.
+
+Similar to [duplexer2](https://github.com/deoxxa/duplexer2) except it supports both streams2 and streams1 as input
+and it allows you to set the readable and writable part asynchronously using `setReadable(stream)` and `setWritable(stream)`
+
+```
+npm install duplexify
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/duplexify.svg?style=flat)](http://travis-ci.org/mafintosh/duplexify)
+
+## Usage
+
+Use `duplexify(writable, readable, streamOptions)` (or `duplexify.obj(writable, readable)` to create an object stream)
+
+``` js
+var duplexify = require('duplexify')
+
+// turn writableStream and readableStream into a single duplex stream
+var dup = duplexify(writableStream, readableStream)
+
+dup.write('hello world') // will write to writableStream
+dup.on('data', function(data) {
+  // will read from readableStream
+})
+```
+
+You can also set the readable and writable parts asynchronously
+
+``` js
+var dup = duplexify()
+
+dup.write('hello world') // write will buffer until the writable
+                         // part has been set
+
+// wait a bit ...
+dup.setReadable(readableStream)
+
+// maybe wait some more?
+dup.setWritable(writableStream)
+```
+
+If you call `setReadable` or `setWritable` multiple times it will unregister the previous readable/writable stream.
+To disable the readable or writable part call `setReadable` or `setWritable` with `null`.
+
+If the readable or writable streams emits an error or close it will destroy both streams and bubble up the event.
+You can also explicitly destroy the streams by calling `dup.destroy()`. The `destroy` method optionally takes an
+error object as argument, in which case the error is emitted as part of the `error` event.
+
+``` js
+dup.on('error', function(err) {
+  console.log('readable or writable emitted an error - close will follow')
+})
+
+dup.on('close', function() {
+  console.log('the duplex stream is destroyed')
+})
+
+dup.destroy() // calls destroy on the readable and writable part (if present)
+```
+
+## HTTP request example
+
+Turn a node core http request into a duplex stream is as easy as
+
+``` js
+var duplexify = require('duplexify')
+var http = require('http')
+
+var request = function(opts) {
+  var req = http.request(opts)
+  var dup = duplexify(req)
+  req.on('response', function(res) {
+    dup.setReadable(res)
+  })
+  return dup
+}
+
+var req = request({
+  method: 'GET',
+  host: 'www.google.com',
+  port: 80
+})
+
+req.end()
+req.pipe(process.stdout)
+```

+# fast-fifo
+
+A fast fifo implementation similar to the one powering nextTick in Node.js core
+
+```
+npm install fast-fifo
+```
+
+Uses a linked list of growing fixed sized arrays to implement the FIFO to avoid
+allocating a wrapper object for each item.
+
+## Usage
+
+``` js
+const FIFO = require('fast-fifo')
+
+const q = new FIFO()
+
+q.push('hello')
+q.push('world')
+
+q.shift() // returns hello
+q.shift() // returns world
+```
+
+## API
+
+#### `q = new FIFO()`
+
+Create a new FIFO.
+
+#### `q.push(value)`
+
+Push a value to the FIFO. `value` can be anything other than undefined.
+
+#### `value = q.shift()`
+
+Return the oldest value from the FIFO.
+
+#### `bool = q.isEmpty()`
+
+Returns `true` if the FIFO is empty and false otherwise.
+
+## Benchmarks
+
+Included in bench.js is a simple benchmark that benchmarks this against a simple
+linked list based FIFO.
+
+On my machine the benchmark looks like this:
+
+```
+fifo bulk push and shift: 2881.508ms
+fifo individual push and shift: 3248.437ms
+fast-fifo bulk push and shift: 1606.972ms
+fast-fifo individual push and shift: 1328.064ms
+fifo bulk push and shift: 3266.902ms
+fifo individual push and shift: 3320.944ms
+fast-fifo bulk push and shift: 1858.307ms
+fast-fifo individual push and shift: 1516.983ms

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+# pretty-bytes [![Build Status](https://travis-ci.org/sindresorhus/pretty-bytes.svg?branch=master)](https://travis-ci.org/sindresorhus/pretty-bytes)
+
+> Convert bytes to a human readable string: `1337` → `1.34 kB`
+
+Useful for displaying file sizes for humans.
+
+*Note that it uses base-10 (e.g. kilobyte).
+[Read about the difference between kilobyte and kibibyte.](https://web.archive.org/web/20150324153922/https://pacoup.com/2009/05/26/kb-kb-kib-whats-up-with-that/)*
+
+
+## Install
+
+```
+$ npm install pretty-bytes
+```
+
+
+## Usage
+
+```js
+const prettyBytes = require('pretty-bytes');
+
+prettyBytes(1337);
+//=> '1.34 kB'
+
+prettyBytes(100);
+//=> '100 B'
+
+// Display with units of bits
+prettyBytes(1337, {bits: true});
+//=> '1.34 kbit'
+
+// Display file size differences
+prettyBytes(42, {signed: true});
+//=> '+42 B'
+
+// Localized output using German locale
+prettyBytes(1337, {locale: 'de'});
+//=> '1,34 kB'
+```
+
+
+## API
+
+### prettyBytes(number, [options])
+
+#### number
+
+Type: `number`
+
+The number to format.
+
+#### options
+
+Type: `object`
+
+##### signed
+
+Type: `boolean`<br>
+Default: `false`
+
+Include plus sign for positive numbers. If the difference is exactly zero a space character will be prepended instead for better alignment.
+
+##### bits
+
+Type: `boolean`<br>
+Default: `false`
+
+Format the number as [bits](https://en.wikipedia.org/wiki/Bit) instead of [bytes](https://en.wikipedia.org/wiki/Byte). This can be useful when, for example, referring to [bit rate](https://en.wikipedia.org/wiki/Bit_rate).
+
+##### locale
+
+Type: `boolean` `string`<br>
+Default: `false` *(No localization)*
+
+- If `true`: Localize the output using the system/browser locale.
+- If `string`: Expects a [BCP 47 language tag](https://en.wikipedia.org/wiki/IETF_language_tag) (For example: `en`, `de`, …)
+
+**Note:** Localization should generally work in browsers. Node.js needs to be [built](https://github.com/nodejs/node/wiki/Intl) with `full-icu` or `system-icu`. Alternatively, the [`full-icu`](https://github.com/unicode-org/full-icu-npm) module can be used to provide support at runtime.

+
+> Easily format the time from node.js `process.hrtime`. Works with timescales ranging from weeks to nanoseconds.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save pretty-time
+```
+
+## Usage
+
+```js
+var pretty = require('pretty-time');
+
+var start = process.hrtime();
+var time = process.hrtime(start);
+console.log(pretty(time));
+//=> 3μs
+```
+
+## API
+
+By default, when no time increment is given as the second argument, the closest timescale is used (e.g. _most granular without being less than zero_).
+
+**Examples:**
+
+```js
+pretty([1200708, 795428088]);
+//=> '2w'
+
+pretty([800708, 795428088]);
+//=> '1w'
+
+pretty([400708, 795428088]);
+//=> '5d'
+
+pretty([70708, 795428088]);
+//=> '20h'
+
+pretty([12708, 795428088]);
+//=> '4h'
+
+pretty([3708, 795428088]);
+//=> '1h'
+
+pretty([208, 795428088]);
+//=> '3m'
+
+pretty([20, 795428088]);
+//=> '21s'
+
+pretty([0, 795428088]);
+//=> '795ms'
+
+pretty([0, 000428088]);
+//=> '428μs'
+
+pretty([0, 000000088]);
+//=> '88ns'
+
+pretty([0, 000000018]);
+//=> '18ns'
+```
+
+### Minimum time increment
+
+_(All of the following examples use `[6740, 795428088]` as the hrtime array.)_
+
+This value is passed as the second argument and determines how granular to make the time.
+
+**Examples**
+
+```js
+pretty(time, 'h');
+//=> '2h'
+
+pretty(time, 'm');
+//=> '1h 52m'
+
+pretty(time, 's');
+//=> '1h 52m 21s'
+```
+
+**Valid time increments**
+
+Any of the following may be used:
+
+* `ns` | `nano` | `nanosecond` | `nanoseconds`
+* `μs` | `micro` | `microsecond` | `microseconds`
+* `ms` | `milli` | `millisecond` | `milliseconds`
+* `s` | `sec` | `second` | `seconds`
+* `m` | `min` | `minute` | `minutes`
+* `h` | `hr` | `hour` | `hours`
+* `d` | `day` | `days`
+* `w` | `wk` | `week` | `weeks`

+# pumpify
+
+Combine an array of streams into a single duplex stream using [pump](https://github.com/mafintosh/pump) and [duplexify](https://github.com/mafintosh/duplexify).
+If one of the streams closes/errors all streams in the pipeline will be destroyed.
+
+```
+npm install pumpify
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/pumpify.svg?style=flat)](http://travis-ci.org/mafintosh/pumpify)
+
+## Usage
+
+Pass the streams you want to pipe together to pumpify `pipeline = pumpify(s1, s2, s3, ...)`.
+`pipeline` is a duplex stream that writes to the first streams and reads from the last one.
+Streams are piped together using [pump](https://github.com/mafintosh/pump) so if one of them closes
+all streams will be destroyed.
+
+``` js
+var pumpify = require('pumpify')
+var tar = require('tar-fs')
+var zlib = require('zlib')
+var fs = require('fs')
+
+var untar = pumpify(zlib.createGunzip(), tar.extract('output-folder'))
+// you can also pass an array instead
+// var untar = pumpify([zlib.createGunzip(), tar.extract('output-folder')])
+
+fs.createReadStream('some-gzipped-tarball.tgz').pipe(untar)
+```
+
+If you are pumping object streams together use `pipeline = pumpify.obj(s1, s2, ...)`.
+Call `pipeline.destroy()` to destroy the pipeline (including the streams passed to pumpify).
+
+### Using `setPipeline(s1, s2, ...)`
+
+Similar to [duplexify](https://github.com/mafintosh/duplexify) you can also define the pipeline asynchronously using `setPipeline(s1, s2, ...)`
+
+``` js
+var untar = pumpify()
+
+setTimeout(function() {
+  // will start draining the input now
+  untar.setPipeline(zlib.createGunzip(), tar.extract('output-folder'))
+}, 1000)
+
+fs.createReadStream('some-gzipped-tarball.tgz').pipe(untar)
+```

node_modules/readable-stream/GOVERNANCE.md

@@ -0,0 +1,136 @@
+### 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.

+
+```bash

+```
+
+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/v10.18.1/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.
+
+## 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

+# 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
+```
+
+[Get supported safe-buffer with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-safe-buffer?utm_source=npm-safe-buffer&utm_medium=referral&utm_campaign=readme)
+
+## 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).

+
+## 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.

+# streamx
+
+An iteration of the Node.js core streams with a series of improvements.
+
+```
+npm install streamx
+```
+
+[![Build Status](https://travis-ci.org/mafintosh/streamx.svg?branch=master)](https://travis-ci.org/mafintosh/streamx)
+
+## Main improvements from Node.js core stream
+
+#### Proper lifecycle support.
+
+Streams have an `_open` function that is called before any read/write operation and a `_destroy`
+function that is always run as the last part of the stream.
+
+This makes it easy to maintain state.
+
+#### Easy error handling
+
+Fully integrates a `.destroy()` function. When called the stream will wait for any
+pending operation to finish and call the stream destroy logic.
+
+Close is *always* the last event emitted and `destroy` is always ran.
+
+#### `pipe()` error handles
+
+`pipe` accepts a callback that is called when the pipeline is fully drained.
+It also error handles the streams provided and destroys both streams if either
+of them fail.
+
+#### All streams are both binary and object mode streams
+
+A `map` function can be provided to map your input data into buffers
+or other formats. To indicate how much buffer space each data item takes
+an `byteLength` function can be provided as well.
+
+This removes the need for two modes of streams.
+
+#### Simplicity
+
+This is a full rewrite, all contained in one file.
+
+Lots of stream methods are simplified based on how I and devs I work with actually use streams in the wild.
+
+#### Backwards compat
+
+streamx aims to be compatible with Node.js streams whenever it is reasonable to do so.
+
+This means that streamx streams behave a lot like Node.js streams from the outside but still provides the
+improvements above.
+
+## Usage
+
+``` js
+const { Readable } = require('streamx')
+
+const rs = new Readable({
+  read (cb) {
+    this.push('Cool data')
+    cb(null)
+  }
+})
+
+rs.on('data', data => console.log('data:', data))
+```
+
+## API
+
+This streamx package contains 4 streams similar to Node.js core.
+
+## Readable Stream
+
+#### `rs = new stream.Readable([options])`
+
+Create a new readable stream.
+
+Options include:
+
+```
+{
+  highWaterMark: 16384, // max buffer size in bytes
+  map: (data) => data, // optional function to map input data
+  byteLength: (data) => size // optional function that calculates the byte size of input data
+}
+```
+
+In addition you can pass the `open`, `read`, and `destroy` functions as shorthands in
+the constructor instead of overwrite the methods below.
+
+The default byteLength function returns the byte length of buffers and `1024`
+for any other object. This means the buffer will contain around 16 non buffers
+or buffers worth 16kb when full if the defaults are used.
+
+#### `rs._read(cb)`
+
+This function is called when the stream wants you to push new data.
+Overwrite this and add your own read logic.
+You should call the callback when you are fully done with the read.
+
+Can also be set using `options.read` in the constructor.
+
+Note that this function differs from Node.js streams in that it takes
+the "read finished" callback.
+
+#### `drained = rs.push(data)`
+
+Push new data to the stream. Returns true if the buffer is not full
+and you should push more data if you can.
+
+If you call `rs.push(null)` you signal to the stream that no more
+data will be pushed and that you want to end the stream.
+
+#### `data = rs.read()`
+
+Read a piece of data from the stream buffer. If the buffer is currently empty
+`null` will be returned and you should wait for `readable` to be emitted before
+trying again. If the stream has been ended it will also return `null`.
+
+Note that this method differs from Node.js streams in that it does not accept
+an optional amounts of bytes to consume.
+
+#### `rs.unshift(data)`
+
+Add a piece of data to the front of the buffer. Use this if you read too much
+data using the `rs.read()` function.
+
+#### `rs._open(cb)`
+
+This function is called once before the first read is issued. Use this function
+to implement your own open logic.
+
+Can also be set using `options.open` in the constructor.
+
+#### `rs._destroy(cb)`
+
+This function is called just before the stream is fully destroyed. You should
+use this to implement whatever teardown logic you need. The final part of the
+stream life cycle is always to call destroy itself so this function will always
+be called wheather or not the stream ends gracefully or forcefully.
+
+Can also be set using `options.destroy` in the constructor.
+
+Note that the `_destroy` might be called without the open function being called
+in case no read was ever performed on the stream.
+
+#### `rs._predestroy()`
+
+A simple hook that is called as soon as the first `stream.destroy()` call is invoked.
+
+Use this in case you need to cancel pending reads (if possible) instead of waiting for them to finish.
+
+Can also be set using `options.predestroy` in the constructor.
+
+#### `rs.destroy([error])`
+
+Forcefully destroy the stream. Will call `_destroy` as soon as all pending reads have finished.
+Once the stream is fully destroyed `close` will be emitted.
+
+If you pass an error this error will be emitted just before `close` is, signifying a reason
+as to why this stream was destroyed.
+
+#### `rs.pause()`
+
+Pauses the stream. You will only need to call this if you want to pause a resumed stream.
+
+#### `rs.resume()`
+
+Will start reading data from the stream as fast as possible.
+
+If you do not call this, you need to use the `read()` method to read data or the `pipe()` method to
+pipe the stream somewhere else or the `data` handler.
+
+If none of these option are used the stream will stay paused.
+
+#### `writableStream = rs.pipe(writableStream, [callback])`
+
+Efficently pipe the readable stream to a writable stream (can be Node.js core stream or a stream from this package).
+If you provide a callback the callback is called when the pipeline has fully finished with an optional error in case
+it failed.
+
+To cancel the pipeline destroy either of the streams.
+
+#### `rs.on('readable')`
+
+Emitted when data is pushed to the stream if the buffer was previously empty.
+
+#### `rs.on('data', data)`
+
+Emitted when data is being read from the stream. If you attach a data handler you are implicitly resuming the stream.
+
+#### `rs.on('end')`
+
+Emitted when the readable stream has ended and no data is left in it's buffer.
+
+#### `rs.on('close')`
+
+Emitted when the readable stream has fully closed (i.e. it's destroy function has completed)
+
+#### `rs.on('error', err)`
+
+Emitted if any of the stream operations fail with an error. `close` is always emitted right after this.
+
+#### `rs.destroyed`
+
+Boolean property indicating wheather or not this stream has been destroyed.
+
+#### `bool = Readable.isBackpressured(rs)`
+
+Static method to check if a readable stream is currently under backpressure.
+
+### `stream = Readable.from(arrayOrBufferOrStringOrAsyncIterator)
+
+Static method to turn an array or buffer or string or AsyncIterator into a readable stream.
+
+## Writable Stream
+
+#### `ws = new stream.Writable([options])`
+
+Create a new writable stream.
+
+Options include:
+
+```
+{
+  highWaterMark: 16384, // max buffer size in bytes
+  map: (data) => data, // optional function to map input data
+  byteLength: (data) => size // optional function that calculates the byte size of input data
+}
+```
+
+In addition you can pass the `open`, `write`, `flush`, and `destroy` functions as shorthands in
+the constructor instead of overwrite the methods below.
+
+The default byteLength function returns the byte length of buffers and `1024`
+for any other object. This means the buffer will contain around 16 non buffers
+or buffers worth 16kb when full if the defaults are used.
+
+#### `ws._open(cb)`
+
+This function is called once before the first write is issued. Use this function
+to implement your own open logic.
+
+Can also be set using `options.open` in the constructor.
+
+#### `ws._destroy(cb)`
+
+This function is called just before the stream is fully destroyed. You should
+use this to implement whatever teardown logic you need. The final part of the
+stream life cycle is always to call destroy itself so this function will always
+be called wheather or not the stream ends gracefully or forcefully.
+
+Can also be set using `options.destroy` in the constructor.
+
+Note that the `_destroy` might be called without the open function being called
+in case no write was ever performed on the stream.
+
+#### `ws._predestroy()`
+
+A simple hook that is called as soon as the first `stream.destroy()` call is invoked.
+
+Use this in case you need to cancel pending writes (if possible) instead of waiting for them to finish.
+
+Can also be set using `options.predestroy` in the constructor.
+
+#### `ws.destroy([error])`
+
+Forcefully destroy the stream. Will call `_destroy` as soon as all pending reads have finished.
+Once the stream is fully destroyed `close` will be emitted.
+
+If you pass an error this error will be emitted just before `close` is, signifying a reason
+as to why this stream was destroyed.
+
+#### `drained = ws.write(data)`
+
+Write a piece of data to the stream. Returns `true` if the stream buffer is not full and you
+should keep writing to it if you can. If `false` is returned the stream will emit `drain`
+once it's buffer is fully drained.
+
+#### `ws._write(data, callback)`
+
+This function is called when the stream want to write some data. Use this to implement your own
+write logic. When done call the callback and the stream will call it again if more data exists in the buffer.
+
+Can also be set using `options.write` in the constructor.
+
+#### `ws._writev(batch, callback)`
+
+Similar to `_write` but passes an array of all data in the current write buffer instead of the oldest one.
+Useful if the destination you are writing the data to supports batching.
+
+Can also be set using `options.writev` in the constructor.
+
+#### `ws.end()`
+
+Gracefully end the writable stream. Call this when you no longer want to write to the stream.
+
+Once all writes have been fully drained `finish` will be emitted.
+
+#### `ws._final(callback)`
+
+This function is called just before `finish` is emitted, i.e. when all writes have flushed but `ws.end()`
+have been called. Use this to implement any logic that should happen after all writes but before finish.
+
+Can also be set using `options.final` in the constructor.
+
+#### `ws.on('finish')`
+
+Emitted when the stream has been ended and all writes have been drained.
+
+#### `ws.on('close')`
+
+Emitted when the readable stream has fully closed (i.e. it's destroy function has completed)
+
+#### `ws.on('error', err)`
+
+Emitted if any of the stream operations fail with an error. `close` is always emitted right after this.
+
+#### `ws.destroyed`
+
+Boolean property indicating wheather or not this stream has been destroyed.
+
+#### `bool = Writable.isBackpressured(ws)`
+
+Static method to check if a writable stream is currently under backpressure.
+
+## Duplex Stream
+
+#### `s = new stream.Duplex([options])`
+
+A duplex stream is a stream that is both readable and writable.
+
+Since JS does not support multiple inheritance it inherits directly from Readable
+but implements the Writable API as well.
+
+If you want to provide only a map function for the readable side use `mapReadable` instead.
+If you want to provide only a byteLength function for the readable side use `byteLengthReadable` instead.
+
+Same goes for the writable side but using `mapWritable` and `byteLengthWritable` instead.
+
+## Transform Stream
+
+#### `ts = new stream.Transform([options])`
+
+A transform stream is a duplex stream that maps the data written to it and emits that as readable data.
+
+Has the same options as a duplex stream except you can provide a `transform` function also.
+
+#### `ts._transform(data, callback)`
+
+Transform the incoming data. Call `callback(null, mappedData)` or use `ts.push(mappedData)` to
+return data to the readable side of the stream.
+
+Per default the transform function just remits the incoming data making it act as a pass-through stream.
+
+## Contributing
+
+If you want to help contribute to streamx a good way to start is to help writing more test
+cases, compatibility tests, documentation, or performance benchmarks.

+
+***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.

+util-deprecate
+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```
