# ordered-read-streams [](http://badge.fury.io/js/ordered-read-streams) [](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
```
