Sample HTTP server

[creationix]

I ported http-codec from luvit to seaduk and made a minimal HTTP server using this and wrap-socket.

https://github.com/nucleus-js/seaduk/blob/master/test-app/http-server.js

// Load the libraries
var httpCodec = require('deps/http-codec');
var createServer = require("deps/net").createServer;
var uv = require('uv');

// Create a TCP server using HTTP codec as the decoder/encoder
var server = createServer({
  port: 8080,
  encode: httpCodec.encoder(),
  decode: httpCodec.decoder(),
}, function (client) {
  // Read all parsed HTTP messages from the stream
  client.read(onRead);
  function onRead(err, data) {
    if (err) throw err;
    if (data) return client.read(onRead);
    // When we get an empty stream, that means a full request with body has been parsed
    if (data === "") {
      // Let's send a response head
      client.write({
        code: 200,
        headers: [
          "Server", "seaduk",
          "Date", new Date().toUTCString(),
          "Connection", "close",
          "Content-Length", "12",
          "Content-Type", "text/plain",
        ]
      });
      // And response body
      client.write("Hello World\n");
      // And shutdown the stream
      client.write(null, function (err) {
        if (err) throw err;
        print("Closing server");
        server.close();
      });
    }
  }
});

Next step is either to prototype a higher-level HTTP library or implement websockets + msgpack + super-agent-rpc.

Ideas for HTTP library API:

• req.method
• req.getHeader(name) -> value
• req.readNext(callback) - read a single body chunk from the request
• req.readAll(callback) - buffer all input from request
• res.code - response code read/write
• res.setHeader(name, value) - set a response header
• res.addHeader(name, value) - add a response header (won't replace existing header with same key)
• res.delHeader(name)
• res.getHeader(name) -> value
• res.write(chunk, callback) - write a chunk to response (go ahead and send head)
• res.finish(callback) - finish writing response (send head if not sent already)
• res.writeAll(chunk, callback) - write head and body at once
