Generic‑pool is a lightweight Node.js library that provides a configurable, promise‑based pool for any kind of expensive resource (e.g., database connections, network sockets). It lets developers define how resources are created, validated and destroyed, then acquire, release or destroy them with built‑in support for limits, timeouts, priority queues and idle eviction—making it ideal for server‑side applications that need to reuse or throttle costly external services.
