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 } +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 @@ -57,6 +406,19 @@ mp.collect().then(all => { }) ``` +### 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 @@ -122,3 +484,123 @@ async function consume () { 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;
