(more infos on http://www.mathieu-elie.net/portfolio/html6-forgotten-in-html5-teasing-bcbx/) My pres at Barcamp Bordeaux 2012. HTML5 is not only markup. We have a lot of improves in the js API with a deep impact on architecture of tommorow web applications.

1. HTML6*
forgotten in HTML5
* teasing

2. Web Sockets
Bidirectional communication technology for web
apps

3. Web Sockets
Before == polling
GET ?
CLIENT SERVER
DATA
GET ?
CLIENT SERVER
DATA
SERVER
CLIENT
GET ?
SERVER
LOAD !!!
DATA

4. Web Sockets
After == connect and push
Connect
CLIENT SERVER
ACK
CLIENT DATA PUSH SERVER
HAPPY
CLIENT DATA PUSH SERVER SERVER !!

5. Web Storage
Method of storing data locally like cookies, but
for larger amounts of data.
- user return to the site: no server call to get
same state
- browser side caching
- use your brain -> ....

6. Cross-Origin Resource Sharing
Method of performing XMLHttpRequests across
domains
- get on api twitter (and so on.. ) without
server call !! -> happy server and no rate limit
by ip ..

7. Web Workers
Method of running scripts in the background,
isolated from the web page
- stop never ended buggy loops with
setTimeOut
- script does not block page rendering

8. Conclusion
Very technical spec end -> end user dont
understand why but...
on server side things get better:
-> less servers
-> services cheapers for all
-> less power on machines
-> and new groundbreaking services maybe
later....
