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
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 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.
