Who is Sammy?

A Clientside JavaScript Framework 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...
