What is Backbone js?
Backbone.js gives structure to web applications
by providing Models with key-value binding and
custom events,Collections with a rich API of
enumerable functions,Views with declarative
event handling, and connects it all to your
existing API over a RESTful JSON interface.

7. Presenter: Padmalochan, Mindfire Solutions
Why to use Backbone

It encourages you to abstract your data into models and
your DOM manipulation into views and bind the two
together using events.

Need to Build complex UI in Browser.

No More jQuery,no need to store data in DOM, store
data in models instead event binding just works.

If what you plan to build is something where the UI
regularly changes how it displays but does not go to the
server to get entire new pages then you probably need
something like Backbone.js.

Provides a structure into client side application

Architecture
Pros :
1. Fast
2. Highly Interactive.
3. Scalable
Cons:
1. SEO problem (can't
index)
2. Difficult to test
3. Security issues.
1. Routers
2. Models
3. Collection
4. Views

10. Presenter: Padmalochan, Mindfire Solutions
Models

Models are the heart of any JavaScript application, containing the
interactive data as well as a large part of the logic surrounding it:
conversions, validations, computed properties, and access control.

Communicate to View through events.

Provide LifeCycle.

Read attribute with get method and write with set method.

Validation – Validate & isValid

Model Identity

Defaults,initialize.

Backbone.Model vs Backbone.Model.extend

Model have save,fetch and destroy methods for synchronizing with the
server

11. Presenter: Padmalochan, Mindfire Solutions
Collection

Collections group of related model.

Fetch model from server.

Create them and save them back.

Array like object.

12. Presenter: Padmalochan, Mindfire Solutions
Views

The general idea is to organize your interface into logical views,
backed by models, each of which can be updated independently when
the model changes, without having to redraw the page

Handles Model events as well as DOM events.

All views have associated el property.

$el is a Jquery wrapper.

Every view maps to exact one DOM element

Render the UI as you see fit.

Declarative syntax to register handlers for DOM elements.

13. Presenter: Padmalochan, Mindfire Solutions
Templating

Underscore.js Template.

Client-side templatating.Templating happens in views render method.

Dynamically build markup from template and some data.

Backbone doesn't have its own templating engine.
Underscore Templates

<%.... %> - execute arbitary code.

<% ...%> - evaluate an expression and render in result inline.

<% ...%> - evaluate an expression and render html escaped in result inline.
