Caché

A key/value store where pairs can expire after a specified interval

Installation

Add this to your application's shard.yml:

dependencies:
  cache:
    github: mamantoha/cache

Usage

Available stores

• [x] Memory
• [x] Redis
• [ ] Memcached (#2)

require "cache"

Memory

# Set all values to expire after one minute.
cache = Cache::MemoryStore(String, String).new(expires_in: 1.minute)
cache.fetch("today") do
  Time.now.day_of_week
end

Redis

# Set all values to expire after one minute.
cache = Cache::RedisStore(String, String).new(expires_in: 1.minute)
cache.fetch("today") do
  Time.now.day_of_week
end

This assumes Redis was started with a default configuration, and is listening on localhost, port 6379.

You can connect to Redis by instantiating the Redis class.

If you need to connect to a remote server or a different port, try:

redis = Redis.new(host: "10.0.1.1", port: 6380, password: "my-secret-pw", database: "my-database")
cache = Cache::RedisStore(String, String).new(expires_in: 1.minute, cache: redis)
