A scheduler for one-time (non-periodic) asynchronous tasks, designed to manage delayed executions. It features status getters to communicate the execution state, a robust error handling mechanism for capturing uncaught errors, the ability to abort pending executions, and gracefully await the completion of ongoing tasks.

A modern weighted promise semaphore for Node.js projects, ideal for managing workloads with varying processing requirements. It allows limiting the total weight of concurrently executing jobs, ensuring efficient resource utilization. Offering backpressure control for enhanced efficiency, utilizing a communicative API that signals availability.

A modern Promise rate-limiter for Node.js projects, implementing a fixed-window throttling policy. It restricts the number of tasks that can start execution within distinct, non-overlapping time windows. The API provides backpressure control by signaling availability, for enhanced efficiency.
