+# sorted-union-stream
+
+Get the union of two sorted streams
+
+```
+npm install sorted-union-stream
+```
+
+[![build status](https://secure.travis-ci.org/mafintosh/sorted-union-stream.png)](http://travis-ci.org/mafintosh/sorted-union-stream)
+
+## Usage
+
+``` js
+var union = require('sorted-union-stream')
+var from = require('from2-array')
+
+// es.readArray converts an array into a stream
+var sorted1 = from.obj([1,10,24,42,43,50,55])
+var sorted2 = from.obj([10,42,53,55,60])
+
+// combine the two streams into a single sorted stream
+var u = union(sorted1, sorted2)
+
+u.on('data', function(data) {
+  console.log(data)
+})
+u.on('end', function() {
+  console.log('no more data')
+})
+```
+
+Running the above example will print
+
+```
+1
+10
+24
+42
+43
+50
+53
+55
+60
+no more data
+```
+
+## Streaming objects
+
+If you are streaming objects sorting is based on `.key`.
+
+If this property is not present you should add a `toKey` function as the third parameter.
+`toKey` should return an key representation of the data that can be used to compare objects.
+
+_The keys MUST be sorted_
+
+``` js
+var sorted1 = from.obj([{foo:'a'}, {foo:'b'}, {foo:'c'}])
+var sorted2 = from.obj([{foo:'b'}, {foo:'d'}])
+
+var u = union(sorted1, sorted2, function(data) {
+  return data.foo // the foo property is sorted
+})
+
+union.on('data', function(data) {
+  console.log(data)
+});
+```
+
+Running the above will print
+
+```
+{foo:'a'}
+{foo:'b'}
+{foo:'c'}
+{foo:'d'}
+```
