Express Cache Middleware

Express Cache Middleware is an Express.js middleware designed to intercept HTTP responses and cache them, aiming to improve performance for repeated requests. Its current stable version is 1.0.1, last updated over seven years ago. The package operates by leveraging the `cache-manager` library for its caching backend, allowing for flexible storage options (e.g., memory, Redis, etc.) through `cache-manager`'s plugin system. A key differentiator is its backend-agnostic approach and the provision of customizable `getCacheKey` and `hydrate` options, enabling fine-grained control over cache key generation and transformation of cached data before it's sent to the client. However, due to its age, it is only compatible with `cache-manager` version 2.x, which is now deprecated, making it incompatible with modern `cache-manager` versions (3.x and above) and thus challenging to integrate into contemporary projects.
