Ruby Local Cache

Simple cache for Ruby services.

This is not a gem, but only one file that you can copy and use in your own project. This cache is not thread safe and is intended only for serving as a temporary memory cache for a single thread. No database or storage service is required. In-memory, no dependency, just one file of Ruby Class.

1. Initialize the cache as global: Cache = LocalCache.new

That's it! Next, you can cache result of block execution:

CACHE_KEY = 'Module::Class.calculation_result'
Cache.fetch(CACHE_KEY) do
  2 + 2
end
# => 4

or write/read on your own:

CACHE_KEY = 'Module::Class.calculation_result'
if Cache.valid?(CACHE_KEY)
  Cache.read(CACHE_KEY)
else
  Cache.write(CACHE_KEY, 5)
end
# => 5
