sinatra/redis-cache

A simple redis backed cache for Sinatra applications.

Installing

• Add the gem to your Gemfile

  source 'https://rubygems.org'
  gem 'sinatra-redis-cache'

• Require it in your app after including Sinatra

  require 'sinatra/redis-cache'

Using in your app

Use cache_do anywhere you want to cache the output of a block of code.

The following will be cached for 60 seconds with the key test-key.

cache_do('test-key', 60) do
  'do something here'
end

If there is an unexpired object in the cache with the same key, it will be returned. If not, the code will be executed, returned, and stored in the cache.
