Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

yet-another-duration

v1.7.5

Published

This library helps to convert millisecond to duration string.

Readme

Yet Another Duration

Install

npm install yet-another-duration

Usage

toString()

Transform the number of milliseconds into the Duration string.

  • duration(milliseconds, options).toString().
    • options is optional param;
const {duration} = require('yet-another-duration');

const result = duration(1649254321).toString();

console.log(result); // 19d 2h 7m 34s

toTimeSpan()

Transform the number of milliseconds into the Timespan string, eq. 01:12:34:55.

const {duration} = require('yet-another-duration');

const result = duration(131695000).toTimeSpan();

console.log(result); // 01:12:34:55

toISO8601()

Transform the number of milliseconds into the ISO 8601 duration string, eq. P1Y2M10DT2H30M.

const {duration} = require('yet-another-duration');

const result = duration(131695000).toISO8601();

console.log(result); // P0Y0M1DT12H34M55S

toObject()

Transform the number of milliseconds into the Duration object.

  • duration(milliseconds, options).toObject();
    • options is optional param;
const {duration} = require('yet-another-duration');

const r2 = duration(1649254321).toObject();

console.log(r2); // { years: 0, months: 0, days: 19 ... }

Options

interface DurationConfig {
    calculateWeeks?: boolean;
    units?: {
        max?: string,
        min?: string
    };
    string?: {
        trimZerosLeft?: boolean;
        trimZerosRight?: boolean;
        removeZeros?: boolean;
    };
}
  • calculateWeeks true|false - include weeks into calculations;

units options

  • max years|months|weeks|days|hours|minutes|seconds - set max unit for output:
    • If set to hours, then 1m 15d 12h 32m 45s -> 1116h 32m 45s;
  • min years|months|weeks|days|hours|minutes|seconds - set min unit for output:
    • If set to days, then 1m 15d 12h 32m 45s -> 1m 15d;

Both options may be provided together. As example:

  • If max is set to days, min is set to hours: 1m 15d 12h 32m 45s -> 46d 12h;

string options

  • trimZerosLeft true|false - remove zero values from left side of the string:
    • If true, then 0y 0m 0d 2h 0m 30s -> 2h 0m 30s;
  • trimZerosRight true|false - remove zero values from right side of the string:
    • If true, then 0y 0m 5d 12h 0m 0s -> 0y 0m 5d 12h;
    • If both options is set true, then toString() will produce 5d 12h instead of 0y 0m 5d 12h 0m 0s;
  • removeZeros - remove zero values from the string;
    • When removeZeros option is true, then toString() will produce 2h 30s instead of 0y 0m 0d 2h 0m 30s;

Examples

JavaScript

Specifying defaults

const {duration} = require('yet-another-duration');

const timer = duration.defaults({ ... });

timer(1234567).toObject();
  • defaults is not affecting the duration library in another modules.
