measure-it

Measure performance of code blocks

Install

npm install measure-it --save

Usage

Measure One

const measureOf = require('measure-it');

let measure = measureOf('Awesome Code').start();

awesomeCode();

console.log(measure.get());
// 10

console.log(measure.serialize());
// <Awesome Code> 10

Measure Multiple Groups

const measureOf = require('measure-it');

let measure = measureOf('Awesome Code');

measure.start('block 1');

awesomeCode();

measure.stop('block 1').start('block 2');

awesomeCode();

measure.stop('block 2');

console.log(measure.get('block 1'));
// 11
console.log(measure.get('block 2'));
// 12

console.log(measure.serialize());
// <Awesome Code> block 1: 11, block 2: 12

Measure Asynchronous Code Blocks

const measureOf = require('measure-it');

let measure = measureOf('Awesome Code');

measure.start('block 1');

setTimeout(() => {
  measure.stop('block 1').start('block 2');
  console.log(measure.get('block 1'));
  // 1000

  setTimeout(() => {
    measure.stop('block 2');
    console.log(measure.get('block 2'));
    // 1000

    console.log(measure.serialize());
    // <Awesome Code> block 1: 1000, block 2: 1000
  }, 1000);
}, 1000);

Start / Stop Multiple Groups At Once

const measureOf = require('measure-it');

let measure = measureOf('Awesome Code').start('block 1', 'block 2', 'block 3');

awesomeCode();

measure.stop('block 1');

awesomeCode();

measure.stop('block 2', 'block 3');

console.log(measure.get('block 1'));
// 10
console.log(measure.get('block 2'));
// 20
console.log(measure.get('block 3'));
// 20

console.log(measure.serialize());
// <Awesome Code> block 1: 10, block 2: 20, block 3: 20

Measure Progression

const measureOf = require('measure-it');

let measure = measureOf('Awesome Code').start();

awesomeCode();

measure.stop();

awesomeCode();

measure.stop();

console.log(measure.get());
// [10, 20]

console.log(measure.serialize());
// <Awesome Code> 10, 20
