I’m embarking a building out a new iOS HTML5 prototype.
Libraries:
Ratchet HTML/CSS bootstrap for mobile app prototypes. Made by the guys that created Twitter Bootstrap. (Man, they are good at this CSS stuff.)
Junior HTML mobile app framework? (uses Ratchet extensively). Using Junior may not be worthwhile since it requires Zepto. I may choose to use Backbone Marionette which requires jQuery.
Framer Quick way to create click prototypes from Photoshop.
Coding it up:
(Backbone) Building HTML5 Apps with Yeoman and Backbone
(Angularjs) Egghead.io Angular Video Series
Video: Addy Osmani shows how to use Yeoman to create an AngularJS app.
