## 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`.

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.

### 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. When
- `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
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.
- `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` 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`.
- `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.)
- `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.)

You can iterate over streams synchronously or asynchronously in

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.
