ezzy‑cache is a lightweight Node.js library that provides in‑memory caching with support for named “libraries” (scoped caches) and dictionary‑style tries for fast read‑only data such as autocomplete lists. It offers typical cache operations (add, get, remove, flush) plus utilities like enable/disable, timeout handling, and a `getOrElse` method that lazily computes missing values via a promise. The package is aimed at JavaScript developers who need a simple, configurable cache without external dependencies.
