convert-hrtime

What is convert-hrtime?

The convert-hrtime npm package is designed to convert high-resolution time measurements, typically obtained using process.hrtime(), into various time units such as milliseconds, seconds, nanoseconds, etc. This is particularly useful for performance measurement in Node.js applications where precise timing is crucial.

What are convert-hrtime's main functionalities?

Convert to milliseconds

This feature allows the conversion of a high-resolution time to milliseconds. It is useful for logging or measuring execution time in milliseconds.

const convertHrtime = require('convert-hrtime');
const hrtime = process.hrtime();
const milliseconds = convertHrtime(hrtime).milliseconds;

Convert to seconds

This feature enables the conversion of a high-resolution time to seconds. It can be used when a broader time measurement is sufficient for the application's needs.

const convertHrtime = require('convert-hrtime');
const hrtime = process.hrtime();
const seconds = convertHrtime(hrtime).seconds;

Convert to nanoseconds

This feature provides the ability to convert high-resolution time to nanoseconds, offering the highest precision for performance measurement in critical applications.

const convertHrtime = require('convert-hrtime');
const hrtime = process.hrtime();
const nanoseconds = convertHrtime(hrtime).nanoseconds;

Other packages similar to convert-hrtime

pretty-hrtime

pretty-hrtime is a package that also focuses on converting high-resolution time measurements but emphasizes formatting the output into a more human-readable string. Unlike convert-hrtime, which provides numerical conversions, pretty-hrtime is more about readability for logging and display purposes.

time-convert

time-convert offers conversion between various units of time (e.g., hours to minutes, minutes to seconds), including high-resolution time. It provides a broader range of time unit conversions compared to convert-hrtime, which is specifically focused on high-resolution time.

Install

$ npm install convert-hrtime

Usage

import convertHrtime from 'convert-hrtime';

const startTime = process.hrtime.bigint();
expensiveCalculation();
const diff = process.hrtime.bigint() - startTime;

convertHrtime(diff);
