prettyBenching

A simple Deno library, that gives you pretty benchmarking progress and results in the commandline

⚠ The lib is in a very early stage and needs not yet published features of Deno ⚠

Getting started

Add the following to your deps.ts

export {
  prettyBenchmarkResult,
  prettyBenchmartProgress
} from 'https://raw.githubusercontent.com/littletof/prettyBenching/master/mod.ts';

or just simply

import { prettyBenchmarkResult, prettyBenchmartProgress } from 'https://raw.githubusercontent.com/littletof/prettyBenching/master/mod.ts';

prettyBenchmarkProgress

Prints the Deno runBenchmarks() methods progressCb callback values in a nicely readable format.

Usage

Simply add it to runBenchmarks() like below and you are good to go. Using silent: true is encouraged, so the default logs don't interfere

await runBenchmarks({ silent: true }, prettyBenchmarkProgress())

The output would look something like this during running: running

End when finished: finished

Thresholds

You can define thresholds to specific benchmarks and than the times of the runs will be colored respectively

const threshold = {
  "for100ForIncrementX1e6": {green: 0.85, yellow: 1},
  "for100ForIncrementX1e8": {green: 84, yellow: 93},
  "forIncrementX1e9": {green: 900, yellow: 800},
  "forIncrementX1e9x2": {green: 15000, yellow: 18000},
}

runBenchmarks({ silent: true }, prettyBenchmarkProgress({threshold}))

threshold

prettyBenchmarkResults

Prints the Deno runBenchmarks() methods result in a nicely readable format.

Usage

Simply call prettyBenchmarkResult with the desired settings.

With precision you can define, into how many groups should the results be grouped when displaying a multiple run benchmark result

Use the silent: true flag in runBenchmarks, if you dont want to see the default output

// ...add benches...

runBenchmarks()
.then(prettyBenchmarkResult())
.catch((e: any) => {
  console.log(red(e.benchmarkName))
  console.error(red(e.stack));
});

or 

// ...add benches...

runBenchmarks({silent: true})
.then(prettyBenchmarkResult({precision: 5}))
.catch((e: any) => {
  console.log(red(e.benchmarkName))
  console.error(red(e.stack));
});

The output would look something like this: example

Thresholds

You can define thresholds to specific benchmarks and than the times of the runs will be colored respectively

const thresholds = {
  "for100ForIncrementX1e6": {green: 0.85, yellow: 1},
  "for100ForIncrementX1e8": {green: 84, yellow: 93},
  "forIncrementX1e9": {green: 900, yellow: 800},
  "forIncrementX1e9x2": {green: 15000, yellow: 18000},
}

runBenchmarks().then(prettyBenchmarkResult({ precision: 5, threshold }))
.catch((e: any) => {
    console.log(red(e.benchmarkName));
    console.error(red(e.stack));
  },
);
