The first browser war...
Microsoft vs. Netscape!
6. Web APIs - MobileTech conference 2015 - @casarock
Arms race of features
Everyone invented new and "better" features!
support other features? Hell, NO!
7. Web APIs - MobileTech conference 2015 - @casarock
And this happened...
8. Web APIs - MobileTech conference 2015 - @casarock
Standards? Which standards?
"We know what you want!"
W3C - ignored...
9. Web APIs - MobileTech conference 2015 - @casarock
And Web Developers?
Implemented pretty good browser detection
10. Web APIs - MobileTech conference 2015 - @casarock
And Browser vendors?
Browser Vendors wanted to be "supported"
... and this happened:
11. Web APIs - MobileTech conference 2015 - @casarock
Faking User Agents
Mosaic/0.9 // grandmother of all!
Mozilla/2.02 [fr] (WinNT; I) // Netscapes first!
Mozilla/4.0 (compatible; MSIE 4.0; Windows 98) // IE4!
Funny? There are more…
12. Web APIs - MobileTech conference 2015 - @casarock
Faking User Agents - part 2
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11 // Firefox!

Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/124 (KHTML, like Gecko) Safari/125.1 // Safari!
And chrome?
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko)
Chrome/0.2.149.29 Safari/525.13
But Opera?
Opera/8.0 (Windows NT 5.1; U; en)
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.50
Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95
Safari/537.36 OPR/15.0.1147.153
13. Web APIs - MobileTech conference 2015 - @casarock
Faking User Agents - the End
And Spartan?
Mozilla/5.0 (Windows NT 6.4; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/36.0.1985.143 Safari/537.36 Edge/12.0
14. Web APIs - MobileTech conference 2015 - @casarock
At the end
Everything is a Mozilla...
15. Web APIs - MobileTech conference 2015 - @casarock
and Internet Explorer won the
first browser war
Development stopped for 5 years!
"Optimized for IE 6!"
Standards? IE was the standard!
16. Web APIs - MobileTech conference 2015 - @casarock
The second browser war...
The rise of the others
17. Web APIs - MobileTech conference 2015 - @casarock
The others
Other browser vendors raised
They keep standards in mind and develop
them together
18. Web APIs - MobileTech conference 2015 - @casarock
Standards, everywhere standards!
There is not only one "tool" for the internet
19. Web APIs - MobileTech conference 2015 - @casarock
New Feature: Implemented a
STANDARD!
20. Web APIs - MobileTech conference 2015 - @casarock
Competition?
Still exisits, but:
Performance!
Security!
Release cycles!
21. Web APIs - MobileTech conference 2015 - @casarock
Unique characteristic?
Add ons, technical features, developer tools etc..
Developers are being targeted.
22. Web APIs - MobileTech conference 2015 - @casarock
“Make the Internet a better place”
23. Web APIs - MobileTech conference 2015 - @casarock
The web Wins!
24. Web APIs - MobileTech conference 2015 - @casarock
The "mobile" Web
25. Web APIs - MobileTech conference 2015 - @casarock
The "real" mobile Web
26. Web APIs - MobileTech conference 2015 - @casarock
Everything changes...
Web developers want ...
... access to hardware features
... access Calendar, Addressbook
etc.
We got it!
But: Lessons learned from the past
27. Web APIs - MobileTech conference 2015 - @casarock
Standards!
28. Web APIs - MobileTech conference 2015 - @casarock
New technologies need new APIs
Vendors are working together
Service Workers (Google&Mozilla)
Web Components (Google&Mozilla)
WebGL etc.
29. Web APIs - MobileTech conference 2015 - @casarock
“The web is everywhere”
30. Web APIs - MobileTech conference 2015 - @casarock
“The web in your hands”
31. Web APIs - MobileTech conference 2015 - @casarock
Mobiles need new APIs
iPhone 2007: No SDK, just HTML5!
A smartphone without a browser? Unbelieveable!
Smartphones pushed HTML5
32. Web APIs - MobileTech conference 2015 - @casarock
HTML5 based OS
33. Web APIs - MobileTech conference 2015 - @casarock
HTML5 OS needs new APIs
Firefox OS is open source and with standards in mind
Mozilla introduced new APIs for mobile devices
Consistent use of APIs
34. Web APIs - MobileTech conference 2015 - @casarock
APIs submitted to W3C
Adopted by other mobile browsers ...
... and desktop browsers
more features, more fun!

Definition
“WebAPI is a term used to refer to a suite of device compatibility and
access APIs that allow Web apps and content to access device
hardware (such as battery status or the device vibration hardware), as
well as access to data stored on the device (such as the calendar or
contacts list).
By adding these APIs, we hope to expand what the Web can do today
and only proprietary platforms were able to do in the past.”

Conclusion
Standards are cool!
WebAPIs allow us to build cooler web apps
WebAPIs are not a "mobile"-thingy!
The "Web" becomes (more) "native"
