SPDY Server for node.js Build Status

Flattr this

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).

Usage

var spdy = require('spdy'),
    fs = require('fs');

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-specific options
  windowSize: 1024, // Server's window size
};

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

server.listen(443);

And by popular demand - usage with express:

var spdy = require('spdy'),
    express = require('express'),
    fs = require('fs');

var options = { /* the same as above */ };

var app = express();

app.use(/* your favorite middleware */);

var server = spdy.createServer(options, app);

server.listen(443);

API

API is compatible with http and https module, but you can use another function as base class for SPDYServer.

spdy.createServer(
  [base class constructor, i.e. https.Server],
  { /* 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 three custom properties are added to both of them: streamID, isSpdy, spdyVersion. The first one indicates on which spdy stream are sitting request and response. Second is always true and can be checked to ensure that incoming request wasn't received by HTTPS fallback and last one is a number representing used SPDY protocol version (2 or 3 for now).

Push streams

It is possible to initiate 'push' streams to send content to clients before the client requests it.

spdy.createServer(options, function(req, res) {
  var headers = { 'content-type': 'application/javascript' };
  res.push('/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 is accomplished via the push() method invoked on the current response object (this works for express.js response objects as well). The format of the push() method is:

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

Additional options:

  • plain - if defined, server will accept only plain (non-encrypted) connections.
