Backbone + Rails - Journey to the Front End [Atlanta Ruby Meetup]

1. BACKBONE + RAILS { Journey to the Front End }

2. MY BACKGROUND

3. Looking Back • Came from MVC PHP :-( before 2011 ‣ CodeIgniter • Built internal CRM’s • Used jQuery / AJAX for front end logic ‣ Spaghetti code ‣ One giant file ‣ Perplexing... never felt right • Started Ruby on Rails - late 2011 Backbone + Rails: Journey to the Front End

4. FIRST IMPRESSIONS

5. BACKEND AWESOME

6. FRONTEND TERRIBLE

7. GOOD-LUCK WITH JQUERY_UJS

8. THE PROBLEM DOMAIN

10. Pandora Google Analytics WuFoo Rdio

11. (UN)FORTUNATELY THAT’S OUR APP

12. BETTER.

13. FASTER.

14. CHEAPER.

15. ...and with only 1 developer

16. THIS AIN’T GONNA WORK

17. What solves this problem? • + Give logical structure to the DOM • + Separate behavior, presentation, and implementation • + Automatically keep view changes in sync • + Prevent jQuery spaghetti code callbacks Backbone + Rails: Journey to the Front End

18. What solves this problem? • + Give logical structure to the DOM • + Separate behavior, presentation, and implementation • + Automatically keep view changes in sync • + Prevent jQuery spaghetti code callbacks = Javascript MVC Frameworks Backbone + Rails: Journey to the Front End

19. Diﬀicult Questions • What’s the best Framework? • What are the diﬀerences between... ‣ Backbone JS Jan 2012 ‣ Ember JS ‣ Knockout JS ‣ ... Spine ... Batman ... Angular ... Backbone + Rails: Journey to the Front End

20. Why I Chose Backbone • Highly successful production-ready track record ‣ Major players using it successfully • Non-intimidating documentation • Seemed to be built for Rails out of the box ‣ REST API - No Configuration • Awesome community support ‣ Lots of tutorials ‣ Stack Overflow Backbone + Rails: Journey to the Front End

21. How Backbone Works • Introduces the concepts of Client Side MVC ‣ View - managing particular DOM node (template) ‣ Models / Collections - storing state of entities ‣ Router - Interprets client side URL / fires events ‣ Events - communication mechanism between components • The Ramifications ‣ No more mixed presentation and behavior ‣ You’re in control of everything, all interactions ‣ Enough basic structure to build widgets / small SPA’s Backbone + Rails: Journey to the Front End
