Engine.IO manual required

Hi, I am trying to use Engine.IO. As stated here, StackOverflow expects to use the low level version of Socket.IO. It should also be better and newer. It should also give me the ability to easily exchange messages between the browser client and the Node.js server. Doh.

I read from top to bottom these two pages:

https://github.com/LearnBoost/engine.io

https://github.com/learnboost/engine.io-client

But it doesn’t help, these manuals seem to be written for those who already know how to use this technology not for those who are trying to learn it. Even the main parts are missing.

How is the client script supposed to get into the browser?

What is the landing address for "hello world" that I have to enter in the browser?

Step-by-step instructions for getting started?

Please, help! It’s not easy when you try to learn something like that!

This should be a client script:

<script src="/path/to/engine.io.js"></script>
<script>
  var socket = new eio.Socket('ws://localhost/');
  socket.on('open', function () {
    socket.on('message', function (data) { });
    socket.on('close', function () { });
  });
</script>

But what is it? Index.html? What does all of this mean? How to use it?

Now here is the "server" part:

(A) Listening on a port

var engine = require('engine.io')
  , server = engine.listen(80)

server.on('connection', function (socket) {
  socket.send('utf 8 string');
});
(B) Intercepting requests for a http.Server

var engine = require('engine.io')
  , http = require('http').createServer().listen(3000)
  , server = engine.attach(http)

server.on('connection', function (socket) {
  socket.on('message', function () { });
  socket.on('close', function () { });
});
(C) Passing in requests

var engine = require('engine.io')
  , server = new engine.Server()

server.on('connection', function (socket) {
  socket.send('hi');
});

// …
httpServer.on('upgrade', function (req, socket, head) {
  server.handleUpgrade(req, socket, head);
});
httpServer.on('request', function (req, res) {
  server.handleRequest(req, res);
});

Why is it broken into three parts? Which one matches the client example? Maybe I sound stupid, but how to get a "hello world"?

I would advise you to read the next book, it will remove some of your problems. " http://www.nodebeginner.org/ ".

Then try making the first NodeJS application just do what the book says, so you take care of that a bit.

"socket.io" " http://net.tutsplus.com/tutorials/javascript-ajax/real-time-chat-with-nodejs-socket-io-and-expressjs/".

, engine.io, . engine.io "NodeJS" "socket.io" .
