Introduction

Measures time of passed functions with their arguments and returns the time of function working in milliseconds.

Installation

NPM

npm install performy --save

Basic usage

Importing:

import perfomy from 'perfomy';

API:

ExecuteOnce:

Will display the time of function working.

Options:

• function - Body of the function
• params - Array or list of params if it exists

const testFetchData = () => {
    fetch('http://testurl.com')
    .then((resp) => resp.json())
    .then(function(data) {
        let data = data.results;
    });
}
// Performance test running
performy.executeOnce(testFetchData);

Expected result:

----- [performance test start] -----
Function "mathTest" fulfilled in 9.7 ms
 ----- [performance test end] -----

ExecuteAvg:

Will display the average time of N-times of function working.

Options:

• function - Body of the function
• times - How many times function will be executed
• params - Array or list of params if it exists

const testMath = (a,b) => ((a^b) * (a^b) * (a^b)) / 100;
// Performance test running
performy.executeAvg(testMath, 20, [112, 233]);

Expected result:

----- [performance test start] -----
Function "mathTest" fulfilled in 1.1 ms
 ----- [performance test end] -----

Timer:

It is possible to use performance timer separately.

const testMath = (a,b) => ((a^b) * (a^b) * (a^b)) / 100;
// Set start point
const start = performy.timer.now();
performy.executeAvg(testMath, 20, [112, 233]);
// Set end point
const end = performy.timer.now();
// Display function working time
console.log(end - start);

Expected result:

1.5999999886844307
