Simple File-Based Cache

node-file-cache is a straightforward, file-based caching module for Node.js, currently at version 1.0.2. It leverages `lowdb` for persistent storage, allowing developers to store key-value pairs with optional lifespans and tags for granular expiry. Its design emphasizes simplicity over advanced features or high-throughput performance. Given its age and the explicit mention of Node.js 4.4.5 as a minimum requirement (a version from 2016), it appears to be an unmaintained package with an irregular or non-existent release cadence. It's best suited for small-scale applications where a simple, durable, local cache is sufficient and high concurrency or complex cache invalidation strategies are not required.
