+# ordered-read-streams [![NPM version](https://img.shields.io/npm/v/ordered-read-streams.svg)](http://badge.fury.io/js/ordered-read-streams) [![Build Status](https://travis-ci.org/armed/ordered-read-streams.svg?branch=master)](https://travis-ci.org/armed/ordered-read-streams)
+
+Combines array of streams into one read stream in strict order.
+
+## Installation
+
+`npm install ordered-read-streams`
+
+## Overview
+
+`ordered-read-streams` handles all data/errors from input streams in parallel, but emits data/errors in strict order in which streams are passed to constructor. This is `objectMode = true` stream.
+
+## Example
+
+```js
+var through = require('through2');
+var Ordered = require('ordered-read-streams');
+
+var s1 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 200)
+});
+var s2 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 30)
+});
+var s3 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 100)
+});
+
+var streams = new Ordered([s1, s2, s3]);
+streams.on('data', function (data) {
+  console.log(data);
+})
+
+s1.write('stream 1');
+s1.end();
+
+s2.write('stream 2');
+s2.end();
+
+s3.write('stream 3');
+s3.end();
+```
+Ouput will be:
+
+```
+stream 1
+stream 2
+stream 3
+```
