What is humanize-duration?

The humanize-duration npm package is used to convert durations, given in milliseconds, into human-readable strings. It is useful for displaying time durations in a more understandable format for users.

What are humanize-duration's main functionalities?

Basic Usage

This feature allows you to convert a duration in milliseconds to a human-readable string. In this example, 3000 milliseconds is converted to '3 seconds'.

const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(3000)); // '3 seconds'

Custom Units

This feature allows you to specify custom units for the duration. In this example, 3600000 milliseconds is converted to '1 hour' using hours and minutes as units.

const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(3600000, { units: ['h', 'm'] })); // '1 hour'

Language Support

This feature allows you to specify the language for the output string. In this example, 3000 milliseconds is converted to '3 segundos' in Spanish.

const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(3000, { language: 'es' })); // '3 segundos'

Round

This feature allows you to round the duration to the nearest unit. In this example, 1234567 milliseconds is rounded to '20 minutes'.

const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(1234567, { round: true })); // '20 minutes'

Largest

This feature allows you to limit the number of units in the output string. In this example, 1234567890 milliseconds is converted to '14 days, 6 hours' with a limit of 2 units.

const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(1234567890, { largest: 2 })); // '14 days, 6 hours'

README

Humanize Duration

I have the time in milliseconds and I want it to become "30 minutes" or "3 days, 1 hour". Enter Humanize Duration!

Basic usage

This package is available as humanize-duration in Node and Bower. You can also include the JavaScript in the browser.

In the browser:

<script src="humanize-duration.js"></script>
<script>
humanizeDuration(12000);
</script>

In Node or Browserify:

var humanizeDuration = require("humanize-duration");
humanizeDuration(12000);

Usage

By default, Humanize Duration will humanize down to the second, and will return a decimal for the smallest unit. It will humanize in English by default.

humanizeDuration(3000)      // "3 seconds"
humanizeDuration(2015)      // "2.25 seconds"
humanizeDuration(97320000)  // "1 day, 3 hours, 2 minutes"

You can change the settings by passing options as the second argument:

humanizeDuration(3000, { language: "es" })  // "3 segundos"
humanizeDuration(5000, { language: "ko" })  // "5 초"

humanizeDuration(22140000, { delimiter: " and " })  // "6 hours and 9 minutes"
humanizeDuration(22140000, { delimiter: "--" })     // "6 hours--9 minutes"

humanizeDuration(3600000, { units: ["hours"] })          // 1 hour
humanizeDuration(3600000, { units: ["days", "hours"] })  // 1 hour
humanizeDuration(3600000, { units: ["minutes"] })        // 60 minutes

humanizeDuration(3600000, {
  language: "es",
  units: ["minutes"]
})
// 60 minutos

Humanizers

If you find yourself setting same options over and over again, you can create a humanizer that changes the defaults, which you can still override later.

var spanishHumanizer = humanizeDuration.humanizer({
  language: "es",
  units: ["years", "months", "days"]
});

spanishHumanizer(71177400000)  // "2 años, 3 meses, 2 días"
spanishHumanizer(71177400000, { units: ["days", "hours"] })  // "823 días, 19.5 horas"

Internally, the main humanizeDuration function is just a wrapper around a humanizer.
