LuckyCache

Cache content within your Lucky application.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     lucky_cache:
       github: luckyframework/lucky_cache

2. Run shards install

Usage

require "lucky_cache"

LuckyCache.configure do |settings|
  settings.storage = LuckyCache::MemoryStore.new
  settings.default_duration = 5.minutes
end

class SomeObject
  include LuckyCache::Cachable
end

cache = LuckyCache.settings.storage
some_object = cache.fetch("some_key", as: SomeObject) do
  SomeObject.new
end

Page fragment cache

You can cache portions of your page by including the LuckyCache::HtmlHelpers module in your Page class, and use the cache() helper method.

class Posts::ShowPage < MainLayout
  include LuckyCache::HtmlHelpers
  needs post : Post

  def content
    cache("post:#{post.id}:comments", expires_in: 1.hour) do
      post.comments.each do |comment|
        div comment.text
      end
    end
  end
end
