brolly

benchmark in style

Run benchmarking functions in parallel.

• forks each bench function as child process
• pass module dependencies to bench functions
• pass serialisable values

Install

npm install --save brolly

yarn add brolly

Import

// ES2015
import benchmark from 'brolly'

// CommonJS
var benchmark = require('brolly')

API

benchmark(name, benches[, deps]) : Function

Create a benchmark suite.

If using the deps argument the benches cannot have their own dependency definitions.

• name {String} name of the benchmark suite
• benches {Array} array of benchmark functions
• deps {Array} (optional) shared bench deps

Returns a bench function.

bench(iterations) : self

Run the benchmark suite.

• iterations {Number} number of times to run each bench function

Returns self.

bench.print() : self

Log the results to the console after completion.

Returns self.

Example

import benchmark from 'brolly'

const bench = benchmark('timeout', [
  // use done callback and pass serialisable value to bench fn
  [1000, function timeout (time, done) {
    setTimeout(done, time)
  }],
  // request "delay" lib to be injected into bench fn
  // return Promise instead of calling done callback
  ['delay', function sleep (delay) {
    return delay(1000)
  }]
])

// run each bench 1000 times and then print the results
bench(1000).print()
