SPDY Server for node.js

With this module you can create SPDY servers in node.js with natural http module interface and fallback to regular https (for browsers that doesn't support SPDY yet).

Node+OpenSSL building

At the moment node-spdy requires zlib dictionary support, which will come to node.js only in 0.7.x version. To build 0.7.x version follow instructions below:

git clone git://github.com/joyent/node.git
cd node
./configure --prefix=$HOME/.node/dev # <- or any other dir

make install -j4 # in -jN, N is number of CPU cores on your machine

# Add node's bin to PATH env variable
echo 'export PATH=$HOME/.node/dev/bin:$PATH' >> ~/.bashrc

#
# You have working node 0.7.x + NPN now !!!
#

Usage

var spdy = require('spdy');

var options = {
  key: fs.readFileSync(__dirname + '/keys/spdy-key.pem'),
  cert: fs.readFileSync(__dirname + '/keys/spdy-cert.pem'),
  ca: fs.readFileSync(__dirname + '/keys/spdy-csr.pem')
};

spdy.createServer(options, function(req, res) {
  res.writeHead(200);
  res.end('hello world!');
});

spdy.listen(443);

API

API is compatible with http and https module, but you can use another function as base class for SPDYServer. For example, require('express').HTTPSServer given that as base class you'll get a server compatible with express API.

spdy.createServer(
  [base class constructor, i.e. https.Server or express.HTTPSServer],
  { /* keys and options */ }, // <- the only one required argument
  [request listener]
).listen([port], [host], [callback]);

Request listener will receive two arguments: request and response. They're both instances of http's IncomingMessage and OutgoingMessage. But two custom properties are added to both of them: streamID and isSpdy. The first one indicates on which spdy stream are sitting request and response. Latter one is always true and can be checked to ensure that incoming request wasn't received by HTTPS callback.

Push streams

It's possible to initiate 'push' stream to send content to client, before one'll request it.

spdy.createServer(options, function(req, res) {
  var headers = { 'content-type': 'application/javascript' };
  res.send('/main.js', headers, function(err, stream) {
    if (err) return;

    stream.end('alert("hello from push stream!");');
  });

  res.end('<script src="/main.js"></script>');
}).listen(443);

.push('full or relative url', { ... headers ... }, callback)

You can use either full ( http://host/path ) or relative ( /path ) urls with .push(). headers are the same as for regular response object. callback will receive two arguments: err (if any error is happened) and stream (stream object have API compatible with a net.Socket ).

Options

All options supported by tls are working with node-spdy. In addition, maxStreams options is available. it allows you controlling [maximum concurrent streams][http://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft2#TOC-SETTINGS] protocol option (if client will start more streams than that limit, RST_STREAM will be sent for each additional stream).

CI

Travis doesn't support latest node.js yet, that's why build is failing right now Build Status
