p-profiler

p-profiler is a JavaScript library (v0.2.1, stable) from Microsoft that wraps promise-returning functions to generate Chrome DevTools-compatible profiling JSON. It integrates with concurrency libraries like p-queue and p-graph to trace async task execution, helping developers visualize bottlenecks in promise-heavy workflows. Unlike generic profilers, it targets promise queues and graph-based task scheduling, outputting a trace file that can be loaded into browser DevTools for flamechart analysis. Ships TypeScript definitions. Release cadence is low; primarily a utility for debugging concurrent async operations.
