P-Limit is a JavaScript utility for controlling how many promise-returning or asynchronous functions execute at the same time. Developers create a limiter with a chosen concurrency level and run tasks through it instead of launching every operation immediately. The library works in both Node.js and modern browsers. It exposes counts for currently active and waiting tasks so applications can inspect workload state. Pending work can be cleared, and an optional setting can reject discarded promises with an AbortError. ...

why-is-node-running is a diagnostic tool for Node.js developers that helps answer the question: “why is my Node.js process still alive?” In complex asynchronous code — with timers, open handles, network sockets, file watchers, or unfulfilled promises — it can be tricky to figure out what is preventing the event loop from exiting. This utility inspects the active handles and resources in the runtime, prints a breakdown of open callbacks, sockets, timers, and other tasks, and explains what’s keeping Node running, helping you track down leaks or unintended resource retention. ...
