JSONCache

A simple JSON Cache for use with HTTP APIs.

Add this line to your application's Gemfile:

gem 'jsoncache'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jsoncache

Include it in the class or module you want to use it in.

extend JSONCache

To enable caching for a method use the include class method cache.

cache :expensive_method, expiry: 300

Note: the cache method call has to come after the method definition.

require 'jsoncache'

Class A
  extend JSONCache

  def expensive_method(args)
    # code
  end

  cache :expensive_method, expiry: 300
end

The cache method will the existing method and provide it with caching to the local filesystem. You can set a TTL (time to live) for the cache by setting the expiry value in seconds.
