##Notes

• Follow 12 factor design (include the rails_12factor gem)
• Don't forget your Procfile with the command to start up your application server
• I prefer using external hosted logging services like Logentries (not in this guide)
• Set up performance monitoring AppSignal or New Relic (not in this guide)

Setup for Cuba in a sample app

I recently read up quite some articles on microframworks and I liked the idea to try out Cuba instead of the regular Sinatra for a change. Here is what I ended up with.

First of all my Gemfile:

source "https://rubygems.org"
ruby "2.0.0"

tyteen4a03

// from https://github.com/Shopify/liquid/blob/63eb1aac69a31d97e343822b973b3a51941c8ac2/performance/shopify/shop_filter.rb#L100
Shopify.handleize = function (str) {
    str = str.toLowerCase();

    var toReplace = ['"', "'", "\\", "(", ")", "[", "]"];
    
    // For the old browsers
    for (var i = 0; i < toReplace.length; ++i) {
        str = str.replace(toReplace[i], "");
    }
