Ahungry Profiler

Project page:

https://github.com/ahungry/ahungry-profiler

A nodejs library for easily and recursively wrapping an entire codebase in a profiler to measure function execution time, without requiring complicated instrumenting using nodejs --prof or nodejs --prof-process (or manually instrumenting each function call).

Makes use of ahungry-around for easily binding the profile function to each module/function recursively.

Goal

To achieve useful (beginner readable) profiling in a few seconds for an entire codebase.

Usage

See a sample in tests/test.js:

const { AhungryProfiler } = require('../index')
const { HelloWorld } = require('./HelloWorld')

void async function main () {
  const ap = new AhungryProfiler('AppProfile')
  ap.init(module)

  const hw = new HelloWorld()
  await hw.flub('Greetings') // make async to simulate a delay
  HelloWorld.blub()

  console.log(ap.fin())
}()

Which will produce output as such:

$ node ./tests/test.js
Sleeping for a half of a second...
Sleeping for a third of a second...
Greetings
blub
AppProfile

                                                  ▇  [0ms] - blub []
                                                  ▇  [0ms] - log ["blub"]
                                                  ▇  [NOT_END] - fin []
