 # minizlib
 
-A tiny fast zlib stream built on [minipass](http://npm.im/minipass)
-and Node.js's zlib binding.
+A fast zlib stream built on [minipass](http://npm.im/minipass) and
+Node.js's zlib binding.
 
 This module was created to serve the needs of
-[node-tar](http://npm.im/tar) v2.  If your needs are different, then
-it may not be for you.
+[node-tar](http://npm.im/tar) and
+[minipass-fetch](http://npm.im/minipass-fetch).
+
+Brotli is supported in versions of node with a Brotli binding.
 
 ## How does this differ from the streams in `require('zlib')`?
 
 First, there are no convenience methods to compress or decompress a
 buffer.  If you want those, use the built-in `zlib` module.  This is
-only streams.
+only streams.  That being said, Minipass streams to make it fairly easy to
+use as one-liners: `new zlib.Deflate().end(data).read()` will return the
+deflate compressed result.
 
 This module compresses and decompresses the data as fast as you feed
 it in.  It is synchronous, and runs on the main process thread.  Zlib
-operations can be high CPU, but they're very fast, and doing it this
-way means much less bookkeeping and artificial deferral.
+and Brotli operations can be high CPU, but they're very fast, and doing it
+this way means much less bookkeeping and artificial deferral.
 
 Node's built in zlib streams are built on top of `stream.Transform`.
 They do the maximally safe thing with respect to consistent
 asynchrony, buffering, and backpressure.
 
-This module _does_ support backpressure, and will buffer output chunks
-that are not consumed, but is less of a mediator between the input and
-output.  There is no high or low watermarks, no state objects, and so
-artificial async deferrals.  It will not protect you from Zalgo.
-
-If you write, data will be emitted right away.  If you write
-everything synchronously in one tick, and you are listening to the
-`data` event to consume it, then it'll all be emitted right away in
-that same tick.  If you want data to be emitted in the next tick, then
-write it in the next tick.
-
-It is thus the responsibility of the reader and writer to manage their
-own consumption and process execution flow.
-
-The goal is to compress and decompress as fast as possible, even for
-files that are too large to store all in one buffer.
-
-The API is very similar to the built-in zlib module.  There are
-classes that you instantiate with `new` and they are streams that can
-be piped together.
+See [Minipass](http://npm.im/minipass) for more on the differences between
+Node.js core streams and Minipass streams, and the convenience methods
+provided by that class.

+# minipass
+
+A _very_ minimal implementation of a [PassThrough
+stream](https://nodejs.org/api/stream.html#stream_class_stream_passthrough)
+
+[It's very
+fast](https://docs.google.com/spreadsheets/d/1oObKSrVwLX_7Ut4Z6g3fZW-AX1j1-k6w-cDsrkaSbHM/edit#gid=0)
+for objects, strings, and buffers.
+
+Supports pipe()ing (including multi-pipe() and backpressure
+transmission), buffering data until either a `data` event handler or
+`pipe()` is added (so you don't lose the first chunk), and most other
+cases where PassThrough is a good idea.
+
+There is a `read()` method, but it's much more efficient to consume
+data from this stream via `'data'` events or by calling `pipe()` into
+some other stream.  Calling `read()` requires the buffer to be
+flattened in some cases, which requires copying memory.
+
+There is also no `unpipe()` method.  Once you start piping, there is
+no stopping it!
+
+If you set `objectMode: true` in the options, then whatever is written
+will be emitted.  Otherwise, it'll do a minimal amount of Buffer
+copying to ensure proper Streams semantics when `read(n)` is called.
+
+`objectMode` can also be set by doing `stream.objectMode = true`, or by
+writing any non-string/non-buffer data.  `objectMode` cannot be set to
+false once it is set.
+
+This is not a `through` or `through2` stream.  It doesn't transform
+the data, it just passes it right through.  If you want to transform
+the data, extend the class, and override the `write()` method.  Once
+you're done transforming the data however you want, call
+`super.write()` with the transform output.

+## Differences from Node.js Streams
+
+There are several things that make Minipass streams different from (and in
+some ways superior to) Node.js core streams.
+
+Please read these caveats if you are familiar with noode-core streams and
+intend to use Minipass streams in your programs.
+
+### Timing
+
+Minipass streams are designed to support synchronous use-cases.  Thus, data
+is emitted as soon as it is available, always.  It is buffered until read,
+but no longer.  Another way to look at it is that Minipass streams are
+exactly as synchronous as the logic that writes into them.
+
+This can be surprising if your code relies on `PassThrough.write()` always
+providing data on the next tick rather than the current one, or being able
+to call `resume()` and not have the entire buffer disappear immediately.
+
+However, without this synchronicity guarantee, there would be no way for
+Minipass to achieve the speeds it does, or support the synchronous use
+cases that it does.  Simply put, waiting takes time.
+
+This non-deferring approach makes Minipass streams much easier to reason
+about, especially in the context of Promises and other flow-control
+mechanisms.
+
+### No High/Low Water Marks
+
+Node.js core streams will optimistically fill up a buffer, returning `true`
+on all writes until the limit is hit, even if the data has nowhere to go.
+Then, they will not attempt to draw more data in until the buffer size dips
+below a minimum value.
+
+Minipass streams are much simpler.  The `write()` method will return `true`
+if the data has somewhere to go (which is to say, given the timing
+guarantees, that the data is already there by the time `write()` returns).
+
+If the data has nowhere to go, then `write()` returns false, and the data
+sits in a buffer, to be drained out immediately as soon as anyone consumes
+it.
+
+### Hazards of Buffering (or: Why Minipass Is So Fast)
+
+Since data written to a Minipass stream is immediately written all the way
+through the pipeline, and `write()` always returns true/false based on
+whether the data was fully flushed, backpressure is communicated
+immediately to the upstream caller.  This minimizes buffering.
+
+Consider this case:
+
+```js
+const {PassThrough} = require('stream')
+const p1 = new PassThrough({ highWaterMark: 1024 })
+const p2 = new PassThrough({ highWaterMark: 1024 })
+const p3 = new PassThrough({ highWaterMark: 1024 })
+const p4 = new PassThrough({ highWaterMark: 1024 })
+
+p1.pipe(p2).pipe(p3).pipe(p4)
+p4.on('data', () => console.log('made it through'))
+
+// this returns false and buffers, then writes to p2 on next tick (1)
+// p2 returns false and buffers, pausing p1, then writes to p3 on next tick (2)
+// p3 returns false and buffers, pausing p2, then writes to p4 on next tick (3)
+// p4 returns false and buffers, pausing p3, then emits 'data' and 'drain'
+// on next tick (4)
+// p3 sees p4's 'drain' event, and calls resume(), emitting 'resume' and
+// 'drain' on next tick (5)
+// p2 sees p3's 'drain', calls resume(), emits 'resume' and 'drain' on next tick (6)
+// p1 sees p2's 'drain', calls resume(), emits 'resume' and 'drain' on next
+// tick (7)
+
+p1.write(Buffer.alloc(2048)) // returns false
+```
+
+Along the way, the data was buffered and deferred at each stage, and
+multiple event deferrals happened, for an unblocked pipeline where it was
+perfectly safe to write all the way through!
+
+Furthermore, setting a `highWaterMark` of `1024` might lead someone reading
+the code to think an advisory maximum of 1KiB is being set for the
+pipeline.  However, the actual advisory buffering level is the _sum_ of
+`highWaterMark` values, since each one has its own bucket.
+
+Consider the Minipass case:
+
+```js
+const m1 = new Minipass()
+const m2 = new Minipass()
+const m3 = new Minipass()
+const m4 = new Minipass()
+
+m1.pipe(m2).pipe(m3).pipe(m4)
+m4.on('data', () => console.log('made it through'))
+
+// m1 is flowing, so it writes the data to m2 immediately
+// m2 is flowing, so it writes the data to m3 immediately
+// m3 is flowing, so it writes the data to m4 immediately
+// m4 is flowing, so it fires the 'data' event immediately, returns true
+// m4's write returned true, so m3 is still flowing, returns true
+// m3's write returned true, so m2 is still flowing, returns true
+// m2's write returned true, so m1 is still flowing, returns true
+// No event deferrals or buffering along the way!
+
+m1.write(Buffer.alloc(2048)) // returns true
+```
+
+It is extremely unlikely that you _don't_ want to buffer any data written,
+or _ever_ buffer data that can be flushed all the way through.  Neither
+node-core streams nor Minipass ever fail to buffer written data, but
+node-core streams do a lot of unnecessary buffering and pausing.
+
+As always, the faster implementation is the one that does less stuff and
+waits less time to do it.
+
+### Immediately emit `end` for empty streams (when not paused)
+
+If a stream is not paused, and `end()` is called before writing any data
+into it, then it will emit `end` immediately.
+
+If you have logic that occurs on the `end` event which you don't want to
+potentially happen immediately (for example, closing file descriptors,
+moving on to the next entry in an archive parse stream, etc.) then be sure
+to call `stream.pause()` on creation, and then `stream.resume()` once you
+are ready to respond to the `end` event.
+
+### Emit `end` When Asked
+
+One hazard of immediately emitting `'end'` is that you may not yet have had
+a chance to add a listener.  In order to avoid this hazard, Minipass
+streams safely re-emit the `'end'` event if a new listener is added after
+`'end'` has been emitted.
+
+Ie, if you do `stream.on('end', someFunction)`, and the stream has already
+emitted `end`, then it will call the handler right away.  (You can think of
+this somewhat like attaching a new `.then(fn)` to a previously-resolved
+Promise.)
+
+To prevent calling handlers multiple times who would not expect multiple
+ends to occur, all listeners are removed from the `'end'` event whenever it
+is emitted.
+
+### Impact of "immediate flow" on Tee-streams
+
+A "tee stream" is a stream piping to multiple destinations:
+
+```js
+const tee = new Minipass()
+t.pipe(dest1)
+t.pipe(dest2)
+t.write('foo') // goes to both destinations
+```
+
+Since Minipass streams _immediately_ process any pending data through the
+pipeline when a new pipe destination is added, this can have surprising
+effects, especially when a stream comes in from some other function and may
+or may not have data in its buffer.
+
+```js
+// WARNING! WILL LOSE DATA!
+const src = new Minipass()
+src.write('foo')
+src.pipe(dest1) // 'foo' chunk flows to dest1 immediately, and is gone
+src.pipe(dest2) // gets nothing!
+```
+
+The solution is to create a dedicated tee-stream junction that pipes to
+both locations, and then pipe to _that_ instead.
+
+```js
+// Safe example: tee to both places
+const src = new Minipass()
+src.write('foo')
+const tee = new Minipass()
+tee.pipe(dest1)
+tee.pipe(dest2)
+stream.pipe(tee) // tee gets 'foo', pipes to both locations
+```
+
+The same caveat applies to `on('data')` event listeners.  The first one
+added will _immediately_ receive all of the data, leaving nothing for the
+second:
+
+```js
+// WARNING! WILL LOSE DATA!
+const src = new Minipass()
+src.write('foo')
+src.on('data', handler1) // receives 'foo' right away
+src.on('data', handler2) // nothing to see here!
+```
+
+Using a dedicated tee-stream can be used in this case as well:
+
+```js
+// Safe example: tee to both data handlers
+const src = new Minipass()
+src.write('foo')
+const tee = new Minipass()
+tee.on('data', handler1)
+tee.on('data', handler2)
+src.pipe(tee)
+```
+
+## USAGE
+
+It's a stream!  Use it like a stream and it'll most likely do what you want.
+
+```js
+const Minipass = require('minipass')
+const mp = new Minipass(options) // optional: { encoding, objectMode }
+mp.write('foo')
+mp.pipe(someOtherStream)
+mp.end('bar')
+```
+
+### OPTIONS
+
+* `encoding` How would you like the data coming _out_ of the stream to be
+  encoded?  Accepts any values that can be passed to `Buffer.toString()`.
+* `objectMode` Emit data exactly as it comes in.  This will be flipped on
+  by default if you write() something other than a string or Buffer at any
+  point.  Setting `objectMode: true` will prevent setting any encoding
+  value.
+
+### API
+
+Implements the user-facing portions of Node.js's `Readable` and `Writable`
+streams.
+
+### Methods
+
+* `write(chunk, [encoding], [callback])` - Put data in.  (Note that, in the
+  base Minipass class, the same data will come out.)  Returns `false` if
+  the stream will buffer the next write, or true if it's still in
+  "flowing" mode.
+* `end([chunk, [encoding]], [callback])` - Signal that you have no more
+  data to write.  This will queue an `end` event to be fired when all the
+  data has been consumed.
+* `setEncoding(encoding)` - Set the encoding for data coming of the
+  stream.  This can only be done once.
+* `pause()` - No more data for a while, please.  This also prevents `end`
+  from being emitted for empty streams until the stream is resumed.
+* `resume()` - Resume the stream.  If there's data in the buffer, it is
+  all discarded.  Any buffered events are immediately emitted.
+* `pipe(dest)` - Send all output to the stream provided.  There is no way
+  to unpipe.  When data is emitted, it is immediately written to any and
+  all pipe destinations.
+* `on(ev, fn)`, `emit(ev, fn)` - Minipass streams are EventEmitters.
+  Some events are given special treatment, however.  (See below under
+  "events".)
+* `promise()` - Returns a Promise that resolves when the stream emits
+  `end`, or rejects if the stream emits `error`.
+* `collect()` - Return a Promise that resolves on `end` with an array
+  containing each chunk of data that was emitted, or rejects if the
+  stream emits `error`.  Note that this consumes the stream data.
+* `concat()` - Same as `collect()`, but concatenates the data into a
+  single Buffer object.  Will reject the returned promise if the stream is
+  in objectMode, or if it goes into objectMode by the end of the data.
+* `read(n)` - Consume `n` bytes of data out of the buffer.  If `n` is not
+  provided, then consume all of it.  If `n` bytes are not available, then
+  it returns null.  **Note** consuming streams in this way is less
+  efficient, and can lead to unnecessary Buffer copying.
+* `destroy([er])` - Destroy the stream.  If an error is provided, then an
+  `'error'` event is emitted.  If the stream has a `close()` method, and
+  has not emitted a `'close'` event yet, then `stream.close()` will be
+  called.  Any Promises returned by `.promise()`, `.collect()` or
+  `.concat()` will be rejected.  After being destroyed, writing to the
+  stream will emit an error.  No more data will be emitted if the stream is
+  destroyed, even if it was previously buffered.
+
+### Properties
+
+* `bufferLength` Read-only.  Total number of bytes buffered, or in the case
+  of objectMode, the total number of objects.
+* `encoding` The encoding that has been set.  (Setting this is equivalent
+  to calling `setEncoding(enc)` and has the same prohibition against
+  setting multiple times.)
+* `flowing` Read-only.  Boolean indicating whether a chunk written to the
+  stream will be immediately emitted.
+* `emittedEnd` Read-only.  Boolean indicating whether the end-ish events
+  (ie, `end`, `prefinish`, `finish`) have been emitted.  Note that
+  listening on any end-ish event will immediateyl re-emit it if it has
+  already been emitted.
+* `writable` Whether the stream is writable.  Default `true`.  Set to
+  `false` when `end()`
+* `readable` Whether the stream is readable.  Default `true`.
+* `buffer` A [yallist](http://npm.im/yallist) linked list of chunks written
+  to the stream that have not yet been emitted.  (It's probably a bad idea
+  to mess with this.)
+* `pipes` A [yallist](http://npm.im/yallist) linked list of streams that
+  this stream is piping into.  (It's probably a bad idea to mess with
+  this.)
+* `destroyed` A getter that indicates whether the stream was destroyed.
+* `paused` True if the stream has been explicitly paused, otherwise false.
+* `objectMode` Indicates whether the stream is in `objectMode`.  Once set
+  to `true`, it cannot be set to `false`.
+
+### Events
+
+* `data` Emitted when there's data to read.  Argument is the data to read.
+  This is never emitted while not flowing.  If a listener is attached, that
+  will resume the stream.
+* `end` Emitted when there's no more data to read.  This will be emitted
+  immediately for empty streams when `end()` is called.  If a listener is
+  attached, and `end` was already emitted, then it will be emitted again.
+  All listeners are removed when `end` is emitted.
+* `prefinish` An end-ish event that follows the same logic as `end` and is
+  emitted in the same conditions where `end` is emitted.  Emitted after
+  `'end'`.
+* `finish` An end-ish event that follows the same logic as `end` and is
+  emitted in the same conditions where `end` is emitted.  Emitted after
+  `'prefinish'`.
+* `close` An indication that an underlying resource has been released.
+  Minipass does not emit this event, but will defer it until after `end`
+  has been emitted, since it throws off some stream libraries otherwise.
+* `drain` Emitted when the internal buffer empties, and it is again
+  suitable to `write()` into the stream.
+* `readable` Emitted when data is buffered and ready to be read by a
+  consumer.
+* `resume` Emitted when stream changes state from buffering to flowing
+  mode.  (Ie, when `resume` is called, `pipe` is called, or a `data` event
+  listener is added.)
+
+### Static Methods
+
+* `Minipass.isStream(stream)` Returns `true` if the argument is a stream,
+  and false otherwise.  To be considered a stream, the object must be
+  either an instance of Minipass, or an EventEmitter that has either a
+  `pipe()` method, or both `write()` and `end()` methods.  (Pretty much any
+  stream in node-land will return `true` for this.)
+
+## EXAMPLES
+
+Here are some examples of things you can do with Minipass streams.
+
+### simple "are you done yet" promise
+
+```js
+mp.promise().then(() => {
+  // stream is finished
+}, er => {
+  // stream emitted an error
+})
+```
+
+### collecting
+
+```js
+mp.collect().then(all => {
+  // all is an array of all the data emitted
+  // encoding is supported in this case, so
+  // so the result will be a collection of strings if
+  // an encoding is specified, or buffers/objects if not.
+  //
+  // In an async function, you may do
+  // const data = await stream.collect()
+})
+```
+
+### collecting into a single blob
+
+This is a bit slower because it concatenates the data into one chunk for
+you, but if you're going to do it yourself anyway, it's convenient this
+way:
+
+```js
+mp.concat().then(onebigchunk => {
+  // onebigchunk is a string if the stream
+  // had an encoding set, or a buffer otherwise.
+})
+```
+
+### iteration
+
+You can iterate over streams synchronously or asynchronously in
+platforms that support it.
+
+Synchronous iteration will end when the currently available data is
+consumed, even if the `end` event has not been reached.  In string and
+buffer mode, the data is concatenated, so unless multiple writes are
+occurring in the same tick as the `read()`, sync iteration loops will
+generally only have a single iteration.
+
+To consume chunks in this way exactly as they have been written, with
+no flattening, create the stream with the `{ objectMode: true }`
+option.
+
+```js
+const mp = new Minipass({ objectMode: true })
+mp.write('a')
+mp.write('b')
+for (let letter of mp) {
+  console.log(letter) // a, b
+}
+mp.write('c')
+mp.write('d')
+for (let letter of mp) {
+  console.log(letter) // c, d
+}
+mp.write('e')
+mp.end()
+for (let letter of mp) {
+  console.log(letter) // e
+}
+for (let letter of mp) {
+  console.log(letter) // nothing
+}
+```
+
+Asynchronous iteration will continue until the end event is reached,
+consuming all of the data.
+
+```js
+const mp = new Minipass({ encoding: 'utf8' })
+
+// some source of some data
+let i = 5
+const inter = setInterval(() => {
+  if (i --> 0)
+    mp.write(Buffer.from('foo\n', 'utf8'))
+  else {
+    mp.end()
+    clearInterval(inter)
+  }
+}, 100)
+
+// consume the data with asynchronous iteration
+async function consume () {
+  for await (let chunk of mp) {
+    console.log(chunk)
+  }
+  return 'ok'
+}
+
+consume().then(res => console.log(res))
+// logs `foo\n` 5 times, and then `ok`
+```
+
+### subclass that `console.log()`s everything written into it
+
+```js
+class Logger extends Minipass {
+  write (chunk, encoding, callback) {
+    console.log('WRITE', chunk, encoding)
+    return super.write(chunk, encoding, callback)
+  }
+  end (chunk, encoding, callback) {
+    console.log('END', chunk, encoding)
+    return super.end(chunk, encoding, callback)
+  }
+}
+
+someSource.pipe(new Logger()).pipe(someDest)
+```
+
+### same thing, but using an inline anonymous class
+
+```js
+// js classes are fun
+someSource
+  .pipe(new (class extends Minipass {
+    emit (ev, ...data) {
+      // let's also log events, because debugging some weird thing
+      console.log('EMIT', ev)
+      return super.emit(ev, ...data)
+    }
+    write (chunk, encoding, callback) {
+      console.log('WRITE', chunk, encoding)
+      return super.write(chunk, encoding, callback)
+    }
+    end (chunk, encoding, callback) {
+      console.log('END', chunk, encoding)
+      return super.end(chunk, encoding, callback)
+    }
+  }))
+  .pipe(someDest)
+```
+
+### subclass that defers 'end' for some reason
+
+```js
+class SlowEnd extends Minipass {
+  emit (ev, ...args) {
+    if (ev === 'end') {
+      console.log('going to end, hold on a sec')
+      setTimeout(() => {
+        console.log('ok, ready to end now')
+        super.emit('end', ...args)
+      }, 100)
+    } else {
+      return super.emit(ev, ...args)
+    }
+  }
+}
+```
+
+### transform that creates newline-delimited JSON
+
+```js
+class NDJSONEncode extends Minipass {
+  write (obj, cb) {
+    try {
+      // JSON.stringify can throw, emit an error on that
+      return super.write(JSON.stringify(obj) + '\n', 'utf8', cb)
+    } catch (er) {
+      this.emit('error', er)
+    }
+  }
+  end (obj, cb) {
+    if (typeof obj === 'function') {
+      cb = obj
+      obj = undefined
+    }
+    if (obj !== undefined) {
+      this.write(obj)
+    }
+    return super.end(cb)
+  }
+}
+```
+
+### transform that parses newline-delimited JSON
+
+```js
+class NDJSONDecode extends Minipass {
+  constructor (options) {
+    // always be in object mode, as far as Minipass is concerned
+    super({ objectMode: true })
+    this._jsonBuffer = ''
+  }
+  write (chunk, encoding, cb) {
+    if (typeof chunk === 'string' &&
+        typeof encoding === 'string' &&
+        encoding !== 'utf8') {
+      chunk = Buffer.from(chunk, encoding).toString()
+    } else if (Buffer.isBuffer(chunk))
+      chunk = chunk.toString()
+    }
+    if (typeof encoding === 'function') {
+      cb = encoding
+    }
+    const jsonData = (this._jsonBuffer + chunk).split('\n')
+    this._jsonBuffer = jsonData.pop()
+    for (let i = 0; i < jsonData.length; i++) {
+      let parsed
+      try {
+        super.write(parsed)
+      } catch (er) {
