+# pumpify
+
+Combine an array of streams into a single duplex stream using [pump](https://github.com/mafintosh/pump) and [duplexify](https://github.com/mafintosh/duplexify).
+If one of the streams closes/errors all streams in the pipeline will be destroyed.
+
+```
+npm install pumpify
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/pumpify.svg?style=flat)](http://travis-ci.org/mafintosh/pumpify)
+
+## Usage
+
+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](https://github.com/mafintosh/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, ...)`.
+Call `pipeline.destroy()` to destroy the pipeline (including the streams passed to pumpify).
+
+### Using `setPipeline(s1, s2, ...)`
+
+Similar to [duplexify](https://github.com/mafintosh/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)
+```

+# duplexify
+
+Turn a writeable and readable stream into a single streams2 duplex stream.
+
+Similar to [duplexer2](https://github.com/deoxxa/duplexer2) except it supports both streams2 and streams1 as input
+and it allows you to set the readable and writable part asynchronously using `setReadable(stream)` and `setWritable(stream)`
+
+```
+npm install duplexify
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/duplexify.svg?style=flat)](http://travis-ci.org/mafintosh/duplexify)
+
+## Usage
+
+Use `duplexify(writable, readable, streamOptions)` (or `duplexify.obj(writable, readable)` to create an object stream)
+
+``` js
+var duplexify = require('duplexify')
+
+// turn writableStream and readableStream into a single duplex stream
+var dup = duplexify(writableStream, readableStream)
+
+dup.write('hello world') // will write to writableStream
+dup.on('data', function(data) {
+  // will read from readableStream
+})
+```
+
+You can also set the readable and writable parts asynchronously
+
+``` js
+var dup = duplexify()
+
+dup.write('hello world') // write will buffer until the writable
+                         // part has been set
+
+// wait a bit ...
+dup.setReadable(readableStream)
+
+// maybe wait some more?
+dup.setWritable(writableStream)
+```
+
+If you call `setReadable` or `setWritable` multiple times it will unregister the previous readable/writable stream.
+To disable the readable or writable part call `setReadable` or `setWritable` with `null`.
+
+If the readable or writable streams emits an error or close it will destroy both streams and bubble up the event.
+You can also explicitly destroy the streams by calling `dup.destroy()`. The `destroy` method optionally takes an
+error object as argument, in which case the error is emitted as part of the `error` event.
+
+``` js
+dup.on('error', function(err) {
+  console.log('readable or writable emitted an error - close will follow')
+})
+
+dup.on('close', function() {
+  console.log('the duplex stream is destroyed')
+})
+
+dup.destroy() // calls destroy on the readable and writable part (if present)
+```
+
+## HTTP request example
+
+Turn a node core http request into a duplex stream is as easy as
+
+``` js
+var duplexify = require('duplexify')
+var http = require('http')
+
+var request = function(opts) {
+  var req = http.request(opts)
+  var dup = duplexify(req)
+  req.on('response', function(res) {
+    dup.setReadable(res)
+  })
+  return dup
+}
+
+var req = request({
+  method: 'GET',
+  host: 'www.google.com',
+  port: 80
+})
+
+req.end()
+req.pipe(process.stdout)
+```
