priority-queue

A functional, data-oriented priority queue (max-heap) for Node.js, version 0.2.1. Designed to be tiny (~150 lines), pure ES module, and — critically — does not allocate memory at runtime after initial creation. It is a preallocated array-based heap offering queue, dequeue, isEmpty, clear, delete, and list operations. Unlike typical priority queue libraries that allocate dynamically, this one is suited for performance-critical or real-time applications where GC pauses must be avoided. The package is actively maintained and has tests via GitHub Actions.
