sylva v0.0.3

Sylva v0.0.2

Sylva is a simple module easy to use for building a socket server.

Design Pattern

CoffeeScript is strongly suggested while using this module

Sylva turn the callback parameter of net.createServer([options],callback) into a "class".

By subclassing SylvaSocket "class", socket events will turn into serials of functions which can be overriden.

You can benifit this design pattern by storing some variables in your subclass.

Usage

error,data,drain,end,close,timeout events of net.Socket are converted into functions named with a leading on and next word first character uppercased in SylvaSocket.

default implements does nothing, you can override them without call super.

onBind(socket) will called after instance of SylvaSocket or its subclass is initialized.

write,end function is also proxied for convenience.

Example

Sylva = {SylvaSocket} = require 'sylva'

class MySocket extends SylvaSocket

  @onBind:(socket)=>
    socket.setKeepAlive true,15000
    socket.setTimeout 0
    socket.setEncoding 'utf8'

  @onData:(data)=>
    console.log data

  @onClose:(has_error)=>
    console.log 'Connection Closed'

server = Sylva.createServer MySocket
server.listen 8888
