p-limit is a popular npm package that enforces concurrency limits on asynchronous operations. It prevents resource exhaustion by limiting the number of promises or asynchronous functions running concurrently. Ideal for controlling API call rates, processing large datasets in batches, or preventing server overload, p-limit offers fine-grained control with a simple, promise-based API. This lightweight utility is essential for optimizing performance and ensuring application stability when dealing with concurrency-intensive tasks.
P-limit's release frequency has been sporadic. Initial releases were in 2016, with periods of no updates followed by bursts. Key versions (2.0.0, 3.0.0, 4.0.0, 5.0.0, 6.0.0, and 7.0.0) mark significant updates. Most recently, August 2025 saw three versions released, a high for a single month, after a dry spell in preceding months.
The npm package "p-limit" experienced significant download growth from February 2024 to August 2025. Downloads surged, peaking in June 2025, before a sharp decline in August 2025. The data for August is incomplete, as it is the current month.
