+
+# Synopsis
+A hybrid streaming middleware kernel backwards compatible with connect.
+
+# Motivation
+The advantage to streaming middlewares is that they do not require buffering the entire stream in order to execute their function.
+
+# Status
+
+[![Build Status](https://secure.travis-ci.org/flatiron/union.png)](http://travis-ci.org/flatiron/union)
+
+# Installation
+There are a few ways to use `union`. Install the library using npm. You can add it to your `package.json` file as a dependancy
+
+```bash
+  $ [sudo] npm install union
+```
+
+## Usage
+Union's request handling is [connect](https://github.com/senchalabs/connect)-compatible, meaning that all existing connect middlewares should work out-of-the-box with union.
+
+**(Union 0.3.x is compatible with connect >= 2.1.0)**
+
+In addition, the response object passed to middlewares listens for a "next" event, which is equivalent to calling `next()`. Flatiron middlewares are written in this manner, meaning they are not reverse-compatible with connect.
+
+### A simple case
+
+``` js
+var fs = require('fs'),
+    union = require('../lib'),
+    director = require('director');
+
+var router = new director.http.Router();
+
+var server = union.createServer({
+  before: [
+    function (req, res) {
+      var found = router.dispatch(req, res);
+      if (!found) {
+        res.emit('next');
+      }
+    }
+  ]
+});
+
+router.get(/foo/, function () {
+  this.res.writeHead(200, { 'Content-Type': 'text/plain' })
+  this.res.end('hello world\n');
+});
+
+router.post(/foo/, { stream: true }, function () {
+  var req = this.req,
+      res = this.res,
+      writeStream;
+
+  writeStream = fs.createWriteStream(Date.now() + '-foo.txt');
+  req.pipe(writeStream);
+
+  writeStream.on('close', function () {
+    res.writeHead(200, { 'Content-Type': 'text/plain' });
+    res.end('wrote to a stream!');
+  });
+});
+
+server.listen(9090);
+console.log('union with director running on 9090');
+```
+
+To demonstrate the code, we use [director](https://github.com/flatiron/director). A light-weight, Client AND Server side URL-Router for Node.js and Single Page Apps!
+
+### A case with connect
+
+Code based on connect
+
+```js
+var connect = require('connect')
+  , http = require('http');
+
+var app = connect()
+  .use(connect.favicon())
+  .use(connect.logger('dev'))
+  .use(connect.static('public'))
+  .use(connect.directory('public'))
+  .use(connect.cookieParser('my secret here'))
+  .use(connect.session())
+  .use(function (req, res) {
+    res.end('Hello from Connect!\n');
+  });
+
+http.createServer(app).listen(3000);
+```
+
+Code based on union
+
+```js
+var connect = require('connect')
+  , union = require('union');
+
+var server = union.createServer({
+  buffer: false,
+  before: [
+    connect.favicon(),
+    connect.logger('dev'),
+    connect.static('public'),
+    connect.directory('public'),
+    connect.cookieParser('my secret here'),
+    connect.session(),
+    function (req, res) {
+      res.end('Hello from Connect!\n');
+    },
+  ]
+}).listen(3000);
+```
+
+### SPDY enabled server example
+
+# API
+
+## union Static Members
+
+### createServer(options)
+The `options` object is required. Options include:
+
+Specification
+
+```
+  function createServer(options)
+
+  @param options {Object}
+  An object literal that represents the configuration for the server.
+
+    @option before {Array}
+    The `before` value is an array of middlewares, which are used to route and serve incoming
+    requests. For instance, in the example, `favicon` is a middleware which handles requests
+    for `/favicon.ico`.
+
+    @option after {Array}
+    The `after` value is an array of functions that return stream filters,
+    which are applied after the request handlers in `options.before`.
+    Stream filters inherit from `union.ResponseStream`, which implements the
+    Node.js core streams api with a bunch of other goodies.
+
+    @option limit {Object}
+    (optional) A value, passed to internal instantiations of `union.BufferedStream`.
+
+    @option https {Object}
+    (optional) A value that specifies the certificate and key necessary to create an instance of
+    `https.Server`.
+
+    @option spdy {Object}
+    (optional) A value that specifies the certificate and key necessary to create an instance of
+    `spdy.Server`.
+
+    @option headers {Object}
+    (optional) An object representing a set of headers to set in every outgoing response
+```
+
+Example
+
+```js
+var server = union.createServer({
+  before: [
+    favicon('./favicon.png'),
+    function (req, res) {
+      var found = router.dispatch(req, res);
+      if (!found) {
+        res.emit('next');
+      }
+    }
+  ]
+});
+```
+
+An example of the `https` or `spdy` option.
+
+``` js
+{
+  cert: 'path/to/cert.pem',
+  key: 'path/to/key.pem',
+  ca: 'path/to/ca.pem'
+}
+```
+
+An example of the `headers` option.
+
+``` js
+{
+  'x-powered-by': 'your-sweet-application v10.9.8'
+}
+```
+
+## Error Handling
+Error handler is similiar to middlware but takes an extra argument for error at the beginning.
+
+```js
+var handle = function (err, req, res) {
+  res.statusCode = err.status;
+  res.end(req.headers);
+};
+
+var server = union.createServer({
+  onError: handle,
+  before: [
+    favicon('./favicon.png'),
+    function (req, res) {
+      var found = router.dispatch(req, res);
+      if (!found) {
+        res.emit('next');
+      }
+    }
+  ]
+});
+```
+
+## BufferedStream Constructor
+This constructor inherits from `Stream` and can buffer data up to `limit` bytes. It also implements `pause` and `resume` methods.
+
+Specification
+
+```
+  function BufferedStream(limit)
+
+  @param limit {Number}
+  the limit for which the stream can be buffered
+```
+
+Example
+
+```js
+var bs = union.BufferedStream(n);
+```
+
+## HttpStream Constructor
+This constructor inherits from `union.BufferedStream` and returns a stream with these extra properties:
+
+Specification
+
+```
+  function HttpStream()
+```
+
+Example
+
+```js
+var hs = union.HttpStream();
+```
+
+## HttpStream Instance Members
+
+### url
+The url from the request.
+
+Example
+
+```js
+httpStream.url = '';
+```
+
+### headers
+The HTTP headers associated with the stream.
+
+Example
+
+```js
+httpStream.headers = '';
+```
+
+### method
+The HTTP method ("GET", "POST", etc).
+
+Example
+
+```js
+httpStream.method = 'POST';
+```
+
+### query
+The querystring associated with the stream (if applicable).
+
+Example
+
+```js
+httpStream.query = '';
+```
+
+## ResponseStream Constructor
+This constructor inherits from `union.HttpStream`, and is additionally writeable. Union supplies this constructor as a basic response stream middleware from which to inherit.
+
+Specification
+
+```
+  function ResponseStream()
+```
+
+Example
+
+```js
+var rs = union.ResponseStream();
+```
+
+# Tests
