Who is Sammy?

A Clientside

Inspired by Sinatra, a server-side
framework from the Ruby World
and created by:
Aaron Quint :: quirkey.com

For single-page apps
(no-reload, a la gmail)

Using the URL Hash
(#...)
http://yourapp.com/#/
http://yourapp.com/#/posts
http://yourapp.com/#/posts/hello-world

Remains bookmarkable
Retains “back” button

Built on jQuery

Tiny
About 7kb when minified

The App

Application Function

Routes
verb + path + callback

Example: a little jQuery

Verbs
GET, POST, PUT, DELETE, and bind

Client-Side Forms
This is where ‘post’ comes in...

Create a “post” route
“posts” have access to a params hash

Route Paths
• Can be a string '#/say_my_name'
• Or a regular expression /#/by_name/(.*)/ params[‘splat’]
• Named params '#/by_name/:name' params[‘name’]

Binding
Routes that respond to internal events

Triggering
Execute bound routes with trigger(event_name, ...)

Bind/Trigger Example

Templates & Partials
ERB style notation. HTML, substitute variables, etc.
Template file: “task_details.html.erb”

Multiple apps, one page
• each app bound to specific element
• unique ID and namespace
• possible to create controller apps for
individual elements, widgets, etc.

Data Storage
• CouchDB
• CloudKit
• Client-side Storage
So many buzzwords, so little time...
