Grape fragment cache.

Features

• Grape fragment cache.

Installation

Add this line to your application's Gemfile:

gem 'grape-present_cache'

And then execute:

$ bundle

Or install it yourself as:

$ gem install grape-present-cache

Usage

module MyApi < Grape::API
  format :json

  include Grape::PresentCache

  resources :posts do
    desc "Return a post"
    get ":id" do
      post = Post.find(params[:id])
      present_cache(key: "post-#{post.id}", expires_in: 2.hours) do
        present :post, post, with: API::Entities::Post
      end
      present :meta, Meta.new, with: API::Entities::Meta
    end
  end
end

Grape::PresentCache will use the current endpoint path and method as cache key prefix.In this example, the cache key will be "#{namespace}":"#{route}":posts:#{:id}:get:post-#{post.id}.

##Configuration

By default GrapePresentCache will use an instance of ActiveSupport::Cache::MemoryStore in a non-Rails and Rails.cache in a Rails environment. You can configure it to use any other cache store.

Grape::PresentCache.configure do |config|
  config.cache = ActiveSupport::Cache::FileStore.new
end

TODO

• Support other methods.(eg: expire, delete_matched, update...)
• Rspec
