Jammit-Sinatra is a jammit wrapper that allows Jammit to work properly in Sinatra/Padrino web apps.
It includes middleware and fixed up view helpers (include_javascripts and include_stylesheets).
To install jammit-sinatra, just use:
gem install jammit-sinatra
If you are using bundler, add it to your project's Gemfile:
gem 'jammit-sinatra'
In your app code, you'll need to register Jammit:
register Jammit
You'll also need to load the jammit configuration file. So in your configure block, run:
::RAILS_ENV = "development" # this is needed to work around a Jammit limitation
Jammit.load_configuration("/path/to/config/assets.yml")
In order to use the include_javascripts and include_stylesheets you'll need to have working implemetnations of javascript_include_tag and stylesheets_include_tag. You can easily pull these helpers into your existing Sinatra app from Padrino. See instructions here.
