HOW TO GET YOUR SANITY BACK WITH SOCKET.IO

YO!I am Danielius Visockas

I had to build a chat

Realtime was a problemAt least for me

Because I’m a ruby developer.

Problem?

✘ Polling✘ Long polling✘ Very long polling✘ Web Sockets✘ SSE✘ Just use some service

No

socket.iowith node.js to the rescue

Socket.io abstracts realtime like jQuery does for Ajax

Supported transports

✘ Web Socket✘ Adobe Flash Sockets✘ Long polling✘ Multipart streaming✘ JSONP Polling✘ Forever iframe

Supported browsers

✘ IE 5.5+✘ Safari 3+✘ Chrome 4+✘ Firefox 3+✘ Opera 10+✘ iSafari✘ Android WebKit✘ WebOs Webkit

It has friends

redisRuby server node &

socket.ioPGsql

Redis PostgreSQL

Client code

Caveats

✘ Security

✘ Adds complexity
