cljs.cache : Clojurescript port of clojure/core.cache

• An underlying CacheProtocol used as the base abstraction for implementing new synchronous caches

• A defcache macro for hooking your CacheProtocol implementations into the Clojurescript associative data capabilities.

• Implementations of some basic caching strategies

  • Least-recently-used (LRUCache)
  • Time-to-live (TTLCache)
  • Naive cache (BasicCache)

• Factory functions for each existing cache type

Example Usage

    (require '[cljs.cache :as cache])
	
    (def C (cache/lru-cache-factory {:a 1, :b 2} :threshold 2))
	
    (if (cache/has? C :c)
      (cache/hit C :c)
      (cache/miss C :c 42))
	
    ;=> {:b 2, :c 42}
	
    (cache/evict C :b)
	
    ;=> {:a 1}
    
    (def C (cache/lru-cache-factory {:a 1, :b 2} :threshold 3))
	
    (if (cache/has? C :c)
      (cache/hit C :c)
      (cache/miss C :c 42))
	
	;=> {:a 1, :b 2, :c 42}
	
	;; Technically in order to see those results at the repl you'd have
	;; to use .-cache but I left it off for clarity since that's what's
	;; in the cache.
	
	(.-cache (cache/evict C :b))
	
	;=> {:a 1}
