map-cache

library0.2.2jsnpmunverified

Basic cache object for storing key-value pairs, version 0.2.2. This package provides a simple MapCache class with get, set, has, and del methods, similar to Lo-dash v3 MapCache. It has minimal dependencies and a straightforward API, but is largely obsolete compared to native Map or modern caches like cache-base. Last updated in 2016, it is in maintenance mode with no recent releases.
