## What it is
A simple API response caching middleware for Express/Node that caches route responses using plain-English durations like '5 minutes'. It supports a built-in memory engine or Redis, with cache grouping, indexing, and manual clearing controls.

## Use cases
- cache express api responses
- add response caching to node rest api
- cache api routes with redis
- avoid hitting database on repeated api calls
- clear cached api responses by group
- simple ttl caching middleware for express

## When to choose
- you want dead-simple route-level response caching in Express or Restify with minimal setup
- you need plain-English TTL durations and optional Redis backing
- you want cache groups, index inspection, and manual clearing out of the box

## When to avoid
- you need fine-grained cache invalidation, stale-while-revalidate, or HTTP cache headers control
- you're not using Express/Restify-style middleware
- you need an actively developed project with recent maintenance
