+# unique-stream
+
+node.js through stream that emits a unique stream of objects based on criteria
+
+[![build status](https://secure.travis-ci.org/eugeneware/unique-stream.png)](http://travis-ci.org/eugeneware/unique-stream)
+
+## Installation
+
+Install via npm:
+
+```
+$ npm install unique-stream
+```
+
+## Examples
+
+### Dedupe a ReadStream based on JSON.stringify:
+
+``` js
+var unique = require('unique-stream')
+ , Stream = require('stream');
+
+// return a stream of 3 identical objects
+function makeStreamOfObjects() {
+ var s = new Stream;
+ s.readable = true;
+ var count = 3;
+ for (var i = 0; i < 3; i++) {
+ setImmediate(function () {
+ s.emit('data', { name: 'Bob', number: 123 });
+ --count && end();
+ });
+ }
+
+ function end() {
+ s.emit('end');
+ }
+
+ return s;
+}
+
+// Will only print out one object as the rest are dupes. (Uses JSON.stringify)
+makeStreamOfObjects()
+ .pipe(unique())
+ .on('data', console.log);
+
+```
+
+### Dedupe a ReadStream based on an object property:
+
+``` js
+// Use name as the key field to dedupe on. Will only print one object
+makeStreamOfObjects()
+ .pipe(unique('name'))
+ .on('data', console.log);
+```
+
+### Dedupe a ReadStream based on a custom function:
+
+``` js
+// Use a custom function to dedupe on. Use the 'number' field. Will only print one object.
+makeStreamOfObjects()
+ .pipe(function (data) {
+ return data.number;
+ })
+ .on('data', console.log);
+```
+
+## Dedupe multiple streams
+
+The reason I wrote this was to dedupe multiple object streams:
+
+``` js
+var aggregator = unique();
+
+// Stream 1
+makeStreamOfObjects()
+ .pipe(aggregator);
+
+// Stream 2
+makeStreamOfObjects()
+ .pipe(aggregator);
+
+// Stream 3
+makeStreamOfObjects()
+ .pipe(aggregator);
+
+aggregator.on('data', console.log);
+```
