speedrunner

Speedtesting/benchmarking library for async functions. It's a simple wrapper around the perf_hooks standard module (Node > 8.5.0). Benchmark the speed of single functions or compare them with other ones.

Installation

npm i speedrunner

Example

const test = require('speedrunner')

// dumb example1
async function one() {
	await JSON.parse("{}")
}

// dumb example2
async function two() {
	await JSON.parse("{}")
	await JSON.parse("{}")
}

// the test itself
// tests can only run in async functions, because you must await them
(async function () {
	(await test(one, 1000)).vs(await test(two, 10000))
})()

API

speedrunner(function, repeats)

Takes an async function to test and a number of how many times the test should run. Repeats a Result.

Result

{
	repeats: number,
	total: number,
	average: number,
	min: number,
	max: number,
	print: function,
	vs: function
}

result.print()

Prints a simple log of the result.

result.vs(other_result)

Compares the result with a different one and logs it.
