pretty-hrtime

What is pretty-hrtime?

The pretty-hrtime package is a small Node.js module that converts high-resolution time tuples (process.hrtime()) to a human-readable string. It is useful for logging and outputting performance timings in a format that is easier to comprehend than raw nanoseconds.

What are pretty-hrtime's main functionalities?

Convert high-resolution time to human-readable format

This feature allows you to take a high-resolution time tuple, such as the output from process.hrtime(), and convert it into a human-readable string that represents the elapsed time in words. This is useful for performance testing or timing operations in your applications.

const prettyHrtime = require('pretty-hrtime');
const start = process.hrtime();
// ... some time passes
const end = process.hrtime(start);
console.log(prettyHrtime(end));

Other packages similar to pretty-hrtime

humanize-duration

The humanize-duration package is similar to pretty-hrtime in that it converts time durations to a human-readable format. However, it is more versatile, supporting multiple languages and a variety of options for customization, such as rounding, units, and language selection.

moment-duration-format

This package is a plugin for the popular Moment.js library and provides functionality to format durations. It is similar to pretty-hrtime but requires Moment.js as a dependency and offers more complex formatting options, including template-based formatting.

pretty-ms

pretty-ms is another package that converts milliseconds to a human-readable string. It is similar to pretty-hrtime but works with millisecond precision instead of nanoseconds. It also offers additional features like compact output and the ability to parse strings back to milliseconds.

process.hrtime() to words

Usage

var prettyHrtime = require('pretty-hrtime');

var start = process.hrtime();
// do stuff
var end = process.hrtime(start);

var words = prettyHrtime(end);
console.log(words); // '1.2 ms'

words = prettyHrtime(end, {verbose:true});
console.log(words); // '1 millisecond 209 microseconds'

words = prettyHrtime(end, {precise:true});
console.log(words); // '1.20958 ms'

Note: process.hrtime() has been available since 0.7.6. See http://nodejs.org/changelog.html and https://github.com/joyent/node/commit/f06abd.
