Sammy is a tiny javascript framework built on top of jQuery inspired by Ruby's Sinatra.


Download sammy.js and install it in your public javascripts directory. Include it in your document AFTER jquery.


Like Sinatra, a Sammy application revolves around 'routes'. Routes in Sammy are a little different, though. Not only can you define 'get' and 'post' routes, but you can also bind routes to custom events triggered by your application.

You set up a Sammy Application by passing a Function to the $.sammy (which is a shortcut for the Sammy.Application constructor).

$.sammy(function() {
  this.get('#/', function() {

Inside the 'app' function() this is the Application. This is where you can configure the application and add routes.

Above, we defined a get() route. When the browser is pointed to #/ the function passed to that route will be run. Inside the route function, this is a Sammy.EventContext. EventContext has a bunch of special methods and properties including a params hash, the ability to redirect, render partials, and more.

Once you've defined an application the only thing left to do is run it. The best-practice behavior is to encapulate run() in a document.ready block:

var app = $.sammy(...)

$(function() {;

This will guarantee that the DOM is loaded before we try to apply functionality to it.
