kiss.io

kiss.io v0.7.0-beta.1

kiss.io is dedicated for creating a better interface and functionality for the great ole' socket.io, following and honoring the K.I.S.S. principle - Keep it Simple, Stupid!

Why kiss.io?

• Sexy API – elegant, simple, sleek, modern, objected-oriented and chainable interface, which makes scalability much much easier.
• Self-contained namespaces – in kiss.io namespaces are stand-alone modules. This approach allows for better scalability and code cleanness.
• No code clutter – Lots of old methods and unnecessary logic were removed/rewritten to match the spirit of kiss.io. We want you to just focus on the important stuff.
• Built-in Router – Because an external plugin for a basic feature is absurd.
• Plugins – Namespaces and sockets are extendable via plugins, which not only offer more modulization, but also extra flexibility!

Installing

$ npm install kiss.io

Debugging

kiss.io uses the debug package utility for monitoring it's activity.
Simply start logging activity to the screen by setting the DEBUG environment variable to kiss.io:* like this:

$ set DEBUG="kiss.io:*"

You can also set DEBUG for each module by itself, by assigning one (or more) of the following values:

kiss.io:server | kiss.io:client | kiss.io:namespace | kiss.io:plugin | kiss.io:router | kiss.io:socket

$ set DEBUG="kiss.io:server,kiss.io:namespace"

Getting Started

Server Side

socket.io style
creates a new kiss.io server (var io), prints a message when a socket is connected, and listens on port 3000.

var kiss = require('kiss.io');
var io   = new kiss();
var main = io.of('/');
 
// socket.io style
main.on('connection', function(socket)
{
    console.log('Welcome %s', socket.id);
    
    socket.once('disconnect', function()
    {
        console.log('Bye bye %s', socket.id);
    });
});
 
io.listen(3000);

kiss.io style
a bit more 'modern', express.js style of writing. registers events for sockets using the event (aka on) method. mounts the main namespace on the server, and start listening on port 3000.

var kiss = require('kiss.io'),
    io   = new kiss();
var main = kiss.Namespace('/');
 
main.event('connection', function(socket)
{
    console.log('Welcome %s', socket.id);
});
 
// you can do it also like this
main
  .event('disconnect')
  .once()
  .triggers(function onDisconnect(socket)
  {
      console.log('Bye Bye %s', socket.id);
  });
 
io
.mount(main)
.listen(3000);

kiss.io + Express.js
this shows the possibility to attach an Express.js instance as the front-end for the kiss.io server, and using multiple routes for manipulating data on the server (sending and recieving messages). also note that in this example we used a singleton instance of server instead of creating a new independent one.

var express = require('express');
var kiss = require('kiss.io'),
    io = kiss();
 
var app = express();
var chat = kiss.Namespace('/chat');
 
app.get('/', function(req, res)
{
    res.status(200).send('Welcome to kiss.io chat!');
});
 
chat.on('connection', function(socket)
{
    console.log('a guest has joined the chat');
});
 
chat.on('send-msg', function(msg)
{
    this.socket
    .broadcast('new-msg', msg, this.socket.id);
});
 
chat.on('new-msg', function(msg, author)
{
    console.log('%s says: %s', author, msg);
});
 
io
.mount(chat)
.attach(app)
.listen(3000);

Client Side

Client side for kiss.io is powered via socket.io-client which you can find via cdnjs.com or the socket.io website.

Use just as you used to. kiss.io uses the same transport mechanism as socket.io (both powered by engine.io) so the logic for client is the same for both kiss.io and socket.io. This is also holds true for socket.io-java-client, socket.io-client-swift and socket.io-client-cpp.
