WebSockets Bring your site to life using joind.in/7407
@boden_c •Ratchet •React Chris
What Are WebSockets ? Push Real-time Bi-directional Live
Use cases • Notifications • Chat/Communication • Statistics • Games
• Anything/Everything
But...Can’t we do that today? Comet
How Comet over HTTP works
it’s slow it’s hard to develop it wastes bandwidth ...and
what’s wrong with that it’s a square peg for a round hole
That’s a lot of requests! (sorry for throwing you under
the bus Travis. I still <3 you!)
How Sockets Work • Client connects to server • Server
accepts connection • An open connection is established/maintained • Client/Server sends message to each other
None
Network Topology
Synchronous Stack Your Traditional Server Processes nginx:80 php-fpm php-fpm php-fpm
php-fpm Your app’s source code Storage
The Event Loop
DEMO TIME!!! Open your terminals and... $ telnet demo.socketo.me 8080
WebSocket Recipe + RFC6455 WebSocket Protocol (PHP) HTML5 WebSocket API
(JavaScript) = goodness
Development Server AND Client share 4 simple events
(speaker note: duck)
It doesn’t! ...much... It’s getting better!
A Shameless Plug Introducing: Ratchet
Ratchet is A pure PHP library to serve WebSockets; it
is: • RFC6455 compliant • asynchronous • unit tested (hi Mr. Grumpy) • loosely coupled • ready to lose limbs
Fun with Numbers Remember how PHP “sucked”?
The anatomy of a Ratchet application: Look familiar?
the actual logic execute the server Full Chat: under 50
loc!
Ratchet Architecture The Decorator design pattern
Components
The Client (JavaScript)
DEMO TIME!!! Open Chrome or Firefox and open your debug
console
4.0+ (2009) 6.0+ (2011) 10.70+ (2012) 5.0+ (2010) 10+ (2012)
Supporting the unsupported Browsers • IE7 • IE8 • IE9
...I saw this the other day... seems legit?
2 Options SockJS Flash
Flash • Very easy to implement • True pollyfill •
They’re IE users anyway • It’s Flash... • Up to 3 second connect • Port blocked by proxies Pros Cons
SockJS • Future proof • Uses native fallbacks • Community
support • No PHP implementation • No sub-protocol support Pros Cons
Going Polyglot
How do we communicate? It’s all about sockets
PHP/Python/Java/Node/Ruby socket or MQ (sync) (async)
DNode ZeroMQ
Practical Development
Today’s Issues • Proxies • Scaling • Use SSL •
??? Problem Solution (time solves all problems)
