The p-profiler library is a class. Simply instantiate a Profiler class to be used to run the task functions (functions that generate a Promise). This example uses p-graph to demonstrate how to use this library. The task functions in this example is wrapped inside a profiler and a promise queue to control concurrency
`js
import Profiler from "p-profiler";
import pGraph from "p-graph";
import PQueue from "p-queue";
const concurrency = 3;
// Create a profiler with the same concurrency as the p-graph
const profiler = new Profiler({ concurrency });
const queue = new PQueue({ concurrency });
const putOnShirt = () =>
queue.add(profiler.run(() => Promise.resolve("put on your shirt")));
const putOnShorts = () =>
queue.add(profiler.run(() => Promise.resolve("put on your shorts")));
const putOnJacket = () =>
queue.add(profiler.run(() => Promise.resolve("put on your jacket")));
const putOnShoes = () =>
queue.add(profiler.run(() => Promise.resolve("put on your shoes")));
const tieShoes = () =>
queue.add(profiler.run(() => Promise.resolve("tie your shoes")));
const graph = [
[putOnShoes, tieShoes],
[putOnShirt, putOnJacket],
[putOnShorts, putOnJacket],
[putOnShorts, putOnShoes],
];
await pGraph(graph).run(); // returns a promise that will resolve when all the tasks are done from this graph in order
// This writes out a
profiler.output();
