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.

An efficient Promise lock for Node.js projects, ensuring mutually exclusive execution of asynchronous tasks. Key features include gracefully awaiting the completion of all currently executing or pending tasks, making it ideal for robust production applications requiring smooth teardown.

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.
