The spdy-transport package is an npm module that provides a stream-based API for SPDY protocol communication. It is designed to work with both SPDY/3.1 and HTTP/2, and it can be used to create SPDY or HTTP/2 servers and clients in Node.js.

What are spdy-transport's main functionalities?

SPDY/HTTP2 server creation

This code sample demonstrates how to create a SPDY/HTTP2 server using the spdy-transport package. The server listens on port 3000 and responds with 'hello world!' to all requests.

const spdy = require('spdy');
const http = require('http');

const server = spdy.createServer({
  spdy: {
    protocols: ['h2', 'spdy/3.1', ...],
    plain: false,
    'x-forwarded-for': true,
    connection: {
      windowSize: 1024 * 1024, // Server's window size
      autoSpdy31: false
    }
  }
}, (req, res) => {
  res.writeHead(200);
  res.end('hello world!');
});

server.listen(3000);

SPDY/HTTP2 client creation

This code sample shows how to create a SPDY/HTTP2 client using the spdy-transport package. The client connects to 'https://www.example.com' and sends a GET request to the root path.

const spdy = require('spdy');
const http2 = require('http2');

const client = spdy.connect('https://www.example.com', (err, socket) => {
  if (err) {
    throw new Error(err);
  }

  const req = http2.request({
    ':method': 'GET',
    ':path': '/'
  });

  req.on('response', (headers) => {
    // handle headers
  });

  req.on('data', (chunk) => {
    // handle data
  });

  req.on('end', () => {
    console.log('request ended');
  });

  req.end();
});

var server = transport.connection.create(socket, {
  protocol: 'http2',
  isServer: true
});

server.on('stream', function(stream) {
  console.log(stream.method, stream.path, stream.headers);
  stream.respond(200, {
    header: 'value'
  });

  stream.on('readable', function() {
    var chunk = stream.read();
    if (!chunk)
      return;

    console.log(chunk);
  });

  stream.on('end', function() {
    console.log('end');
