Considerations (continued)

• Testability• How hard is it going to be to test this?• Tip: driving through the GUI is the most difficult

•Code review• Static code analysis support

•Release Management• Support for single file + config deployment• Integration with config mgmt tools

Considerations (continued)

JS Framework Thoughts

• Too Early To Call• …But you have to pick!• jQuery alone is good but insufficient• Huh? -> jQuery -> Backbone -> AngularJS -> Ember.js

Greenfield 2013 GitHub Project• https://github.com/dynacron-group/greenfield• DropWizard• TestNG

• AngularJS (Angular Seed)• Bootstrap• Jasmine + Karma

• MongoDB• As of 10/14/2013 – early work-in-progress• Feel free to watch, star, contribute, kibitz, add issues…

Why AngularJS?

•Data- attribute approach• Works better with tools• “The way the browsers are going” – Google• Scope databinding magic seems ok• …but there may be edge cases…?

• Really, really strong focus on test-ability
