@marvinh/node-profiler v1.0.0

node profiler

This is a very small module around node's built-in inspector module, because I always forget how to set it up.

Usage

npm install -D @marvinh/node-profiler
# yarn
yarn add -D @marvinh/node-profiler
# pnpm
pnpm add -D @marvinh/node-profiler

Once installed:

import * as fs from "fs";
import { startProfiling } from "@marvinh/node-profiler";

(async () => {
  // Start profiling session
  const stopProfiling = await startProfiling();

  // Do some stuff

  // Collect profile data and write it to disk
  const profile = await stopProfiling();
  // Write to disk
  fs.writeFileSync("./profile.cpuprofile", JSON.stringify(profile));
})();
