# 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/1K_HR5oh3r80b8WVMWCPPjfuWXUgfkmhlX7FGI6JJ8tY/edit?usp=sharing)
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.
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 only be set at instantiation. Attempting to
write something other than a String or Buffer without having set
`objectMode` in the options will throw an error.
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.

## Usage in TypeScript
The `Minipass` class takes three type template definitions:
- `RType` the type being read, which defaults to `Buffer`. If
`RType` is `string`, then the constructor _must_ get an options
object specifying either an `encoding` or `objectMode: true`.
If it's anything other than `string` or `Buffer`, then it
_must_ get an options object specifying `objectMode: true`.
- `WType` the type being written. If `RType` is `Buffer` or
`string`, then this defaults to `ContiguousData` (Buffer,
string, ArrayBuffer, or ArrayBufferView). Otherwise, it
defaults to `RType`.
- `Events` type mapping event names to the arguments emitted
with that event, which extends `Minipass.Events`.
To declare types for custom events in subclasses, extend the
third parameter with your own event signatures. For example:
```js
import { Minipass } from 'minipass'
// a NDJSON stream that emits 'jsonError' when it can't stringify
export interface Events extends Minipass.Events {
jsonError: [e: Error]
}
export class NDJSONStream extends Minipass<string, any, Events> {
constructor() {
super({ objectMode: true })
}
// data is type `any` because that's WType
write(data, encoding, cb) {
try {
const json = JSON.stringify(data)
return super.write(json + '\n', encoding, cb)
} catch (er) {
if (!er instanceof Error) {
er = Object.assign(new Error('json stringify failed'), {
cause: er,
})
}
// trying to emit with something OTHER than an error will
// fail, because we declared the event arguments type.
this.emit('jsonError', er)
}
}
}
const s = new NDJSONStream()
s.on('jsonError', e => {
// here, TS knows that e is an Error
})
```
Emitting/handling events that aren't declared in this way is
fine, but the arguments will be typed as `unknown`.
## 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 node-core
streams and intend to use Minipass streams in your programs.
You can avoid most of these differences entirely (for a very
small performance penalty) by setting `{async: true}` in the
constructor options.
### 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.
Example:
```js
// hybrid module, either works
import { Minipass } from 'minipass'
// or:
const { Minipass } = require('minipass')
const stream = new Minipass()
stream.on('data', () => console.log('data event'))
console.log('before write')
stream.write('hello')
console.log('after write')
// output:
// before write
// data event
// after write
```
### Exception: Async Opt-In
If you wish to have a Minipass stream with behavior that more
closely mimics Node.js core streams, you can set the stream in
async mode either by setting `async: true` in the constructor
options, or by setting `stream.async = true` later on.
```js
// hybrid module, either works
import { Minipass } from 'minipass'
// or:
const { Minipass } = require('minipass')
const asyncStream = new Minipass({ async: true })
asyncStream.on('data', () => console.log('data event'))
console.log('before write')
asyncStream.write('hello')
console.log('after write')
// output:
// before write
// after write
// data event <-- this is deferred until the next tick
```
Switching _out_ of async mode is unsafe, as it could cause data
corruption, and so is not enabled. Example:
```js
import { Minipass } from 'minipass'
const stream = new Minipass({ encoding: 'utf8' })
stream.on('data', chunk => console.log(chunk))
stream.async = true
console.log('before writes')
stream.write('hello')
setStreamSyncAgainSomehow(stream) // <-- this doesn't actually exist!
stream.write('world')
console.log('after writes')
// hypothetical output would be:
// before writes
// world
// after writes
// hello
// NOT GOOD!
```
To avoid this problem, once set into async mode, any attempt to
make the stream sync again will be ignored.
```js
const { Minipass } = require('minipass')
const stream = new Minipass({ encoding: 'utf8' })
stream.on('data', chunk => console.log(chunk))
stream.async = true
console.log('before writes')
stream.write('hello')
stream.async = false // <-- no-op, stream already async
stream.write('world')
console.log('after writes')
// actual output:
// before writes
// after writes
// hello
// world
```
### 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.
Since nothing is ever buffered unnecessarily, there is much less
copying data, and less bookkeeping about buffer capacity levels.
### 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.
However, this is _usually_ not a problem because:
### 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.
### Emit `error` When Asked
The most recent error object passed to the `'error'` event is
stored on the stream. If a new `'error'` event handler is added,
and an error was previously emitted, then the event handler will
be called immediately (or on `process.nextTick` in the case of
async streams).
This makes it much more difficult to end up trying to interact
with a broken stream, if the error handler is added after an
error was previously 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!
```
One 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)
src.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)
```
All of the hazards in this section are avoided by setting `{
async: true }` in the Minipass constructor, or by setting
`stream.async = true` afterwards. Note that this does add some
overhead, so should only be done in cases where you are willing
to lose a bit of performance in order to avoid having to refactor
program logic.
## USAGE
It's a stream! Use it like a stream and it'll most likely do what
you want.
```js
import { Minipass } from 'minipass'
const mp = new Minipass(options) // options is optional
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.
- `async` Defaults to `false`. Set to `true` to defer data
emission until next tick. This reduces performance slightly,
but makes Minipass streams use timing behavior closer to Node
core streams. See [Timing](#timing) for more details.
- `signal` An `AbortSignal` that will cause the stream to unhook
itself from everything and become as inert as possible. Note
that providing a `signal` parameter will make `'error'` events
no longer throw if they are unhandled, but they will still be
emitted to handlers if any are attached.
### 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.
- `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. When
data is emitted, it is immediately written to any and all pipe
destinations. (Or written on next tick in `async` mode.)
- `unpipe(dest)` - Stop piping to the destination stream. This is
immediate, meaning that any asynchronously queued data will
_not_ make it to the destination when running in `async` mode.
- `options.end` - Boolean, end the destination stream when the
source stream ends. Default `true`.
- `options.proxyErrors` - Boolean, proxy `error` events from
the source stream to the destination stream. Note that errors
are _not_ proxied after the pipeline terminates, either due
to the source emitting `'end'` or manually unpiping with
`src.unpipe(dest)`. Default `false`.
- `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` Read-only. The encoding that has been set.
- `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`.
- `pipes` An array of Pipe objects referencing streams that this
stream is piping into.
- `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`.
- `aborted` Readonly property set when the `AbortSignal`
dispatches an `abort` event.
### 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)
return true
} 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++) {
try {
// JSON.parse can throw, emit an error on that
super.write(JSON.parse(jsonData[i]))
} catch (er) {
this.emit('error', er)
continue
}
}
if (cb) cb()
}
}

# minizlib
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) 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 `'node: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. 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
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.
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.
## Classes
- Deflate
- Inflate
- Gzip
- Gunzip
- DeflateRaw
- InflateRaw
- Unzip
- BrotliCompress (Node v10 and higher)
- BrotliDecompress (Node v10 and higher)
- ZstdCompress (Node v22.15 and higher)
- ZstdDecompress (Node v22.15 and higher)
## USAGE
```js
import { BrotliDecompress } from 'minizlib'
// or: const BrotliDecompress = require('minizlib')
const input = sourceOfCompressedData()
const decode = new BrotliDecompress()
const output = whereToWriteTheDecodedData()
input.pipe(decode).pipe(output)
```
## REPRODUCIBLE BUILDS
To create reproducible gzip compressed files across different operating
systems, set `portable: true` in the options. This causes minizlib to set
the `OS` indicator in byte 9 of the extended gzip header to `0xFF` for
'unknown'.
