ytf am i putting these together… in one talk?
ui architecture + web performance
FACT:web performance optimization is 100% about improving the front-end
FACT:87.3019354% of web performance optimization is not actually happening in the front-end
web performance optimization
dynamic loading
RequireJS
Dominoes
LABjs
Loading And Blocking JavaScript
the performance script loader
When NOT to use LABjs
1. If your script uses document.write
2. If your script ITSELF does unsafe DOM-ready detection – does not apply to scripts that use the results of such detection.
When TO use LABjs
1. Everywhere else(actually, wherever you load scripts over-the-wire, and you care about performance, and don’t have a suitable loader already)
FF3 with <script> & <img> tags
FF3.5 with <script> & <img> tags
LABjs in every browser

UI Architecture
how you process, package, deliver to, and communicate with the client/presentation layer

CVCclients views controllers
ui architecture
clients
everything is a client of everything else
decoupled, modular, scalable
views
templating, portable, DRY, platform agnostic,
core web technology
controllers
small, independent, powerful
what i‘m NOT
suggesting
yet another framework
ditch whole architecture
mvc is wrong/weak
CVC is an alternate pattern for UI architecture
what i AM suggesting
it‘s ok to rethink!
JavaScript
(on the server)
BikechainJS
V8 “engine” modules
HandlebarJS{ }
templating engine text/html templates
JSON data input
LABjs on the server
37
Mincir

JavaScript compressor (in JavaScript)
