Koa Spdy

Add the res.push() command to your Koa app. See https://github.com/indutny/node-spdy.

This will probably be included in Koa once node supports HTTP internally. Also note that this only supports push streams, not hints or trailers and stuff.

TO DO:

• Add tests. If someone thinks of a good way to create tests for this...

Usage

var spdify = require('koa-spdy');
var app = require('app');

// augment prototype
spdify(app);
// or use as middleware
app.use(spdify());

SPDY Flags

SPDY flags are passed to this. See https://github.com/indutny/node-spdy#api

var stream = yield this.push(path, [headers], [priority])

If the response is not SPDY, then null will be returned. Otherwise, you may start pushing data. Note: an error might be thrown here and I have no idea why.

app.use(function* (next) {
  if (this.isSpdy) {
    var filename = 'something.txt';
    var stats = yield function (done) {
      fs.stat(filename, done);
    }
    var stream = yield this.push('/' + filename, {
      'content-length': stats.length,
      'content-type': 'text/plain; charset=utf-8'
    });
    fs.createReadStream(filename)
    .on('error', this.onerror)
    .pipe(stream);
  }

  yield* next;
})
