# minipass-pipeline
|
|
|
|
Create a pipeline of streams using Minipass.
|
|
|
|
Calls `.pipe()` on all the streams in the list. Returns a stream where
|
|
writes got to the first pipe in the chain, and reads are from the last.
|
|
|
|
Errors are proxied along the chain and emitted on the Pipeline stream.
|
|
|
|
## USAGE
|
|
|
|
```js
|
|
const Pipeline = require('minipass-pipeline')
|
|
|
|
// the list of streams to pipeline together,
|
|
// a bit like `input | transform | output` in bash
|
|
const p = new Pipeline(input, transform, output)
|
|
|
|
p.write('foo') // writes to input
|
|
p.on('data', chunk => doSomething()) // reads from output stream
|
|
|
|
// less contrived example (but still pretty contrived)...
|
|
const decode = new bunzipDecoder()
|
|
const unpack = tar.extract({ cwd: 'target-dir' })
|
|
const tbz = new Pipeline(decode, unpack)
|
|
|
|
fs.createReadStream('archive.tbz').pipe(tbz)
|
|
|
|
// specify any minipass options if you like, as the first argument
|
|
// it'll only try to pipeline event emitters with a .pipe() method
|
|
const p = new Pipeline({ objectMode: true }, input, transform, output)
|
|
|
|
// If you don't know the things to pipe in right away, that's fine.
|
|
// use p.push(stream) to add to the end, or p.unshift(stream) to the front
|
|
const databaseDecoderStreamDoohickey = (connectionInfo) => {
|
|
const p = new Pipeline()
|
|
logIntoDatabase(connectionInfo).then(connection => {
|
|
initializeDecoderRing(connectionInfo).then(decoderRing => {
|
|
p.push(connection, decoderRing)
|
|
getUpstreamSource(upstream => {
|
|
p.unshift(upstream)
|
|
})
|
|
})
|
|
})
|
|
// return to caller right away
|
|
// emitted data will be upstream -> connection -> decoderRing pipeline
|
|
return p
|
|
}
|
|
```
|
|
|
|
Pipeline is a [minipass](http://npm.im/minipass) stream, so it's as
|
|
synchronous as the streams it wraps. It will buffer data until there is a
|
|
reader, but no longer, so make sure to attach your listeners before you
|
|
pipe it somewhere else.
|
|
|
|
## `new Pipeline(opts = {}, ...streams)`
|
|
|
|
Create a new Pipeline with the specified Minipass options and any streams
|
|
provided.
|
|
|
|
## `pipeline.push(stream, ...)`
|
|
|
|
Attach one or more streams to the pipeline at the end (read) side of the
|
|
pipe chain.
|
|
|
|
## `pipeline.unshift(stream, ...)`
|
|
|
|
Attach one or more streams to the pipeline at the start (write) side of the
|
|
pipe chain.
