Combine an array of streams into a single duplex stream using pump and duplexify
npm install pumpifyCombine an array of streams into a single duplex stream using pump and duplexify.
If one of the streams closes/errors all streams in the pipeline will be destroyed.
``
npm install pumpify
Pass the streams you want to pipe together to pumpify pipeline = pumpify(s1, s2, s3, ...).pipeline is a duplex stream that writes to the first streams and reads from the last one.
Streams are piped together using pump so if one of them closes
all streams will be destroyed.
` js
var pumpify = require('pumpify')
var tar = require('tar-fs')
var zlib = require('zlib')
var fs = require('fs')
var untar = pumpify(zlib.createGunzip(), tar.extract('output-folder'))
// you can also pass an array instead
// var untar = pumpify([zlib.createGunzip(), tar.extract('output-folder')])
fs.createReadStream('some-gzipped-tarball.tgz').pipe(untar)
`
If you are pumping object streams together use pipeline = pumpify.obj(s1, s2, ...).pipeline.destroy()
Call to destroy the pipeline (including the streams passed to pumpify).
Similar to duplexify you can also define the pipeline asynchronously using setPipeline(s1, s2, ...)
` js
var untar = pumpify()
setTimeout(function() {
// will start draining the input now
untar.setPipeline(zlib.createGunzip(), tar.extract('output-folder'))
}, 1000)
fs.createReadStream('some-gzipped-tarball.tgz').pipe(untar)
