pretty-bytes

Formats the given number using `Number#toLocaleString`.

- If locale is a string, the value is expected to be a locale-key (for example: `de`).

- If locale is true, the system default locale is used for translation.

- If no value for locale is specified, the number is returned unmodified.

const toLocaleString = (number, locale) => {

		result = number.toLocaleString(locale);

		throw new TypeError(`Expected a finite number, got ${typeof number}: ${number}`);

	const prefix = isNegative ? '-' : (options.signed ? '+' : '');

		const numberString = toLocaleString(number, options.locale);

		return (isNegative ? '-' : '') + numberString + ' B';

	const exponent = Math.min(Math.floor(Math.log10(number) / 3), UNITS.length - 1);

	number = Number((number / Math.pow(1000, exponent)).toPrecision(3));

	const numberString = toLocaleString(number, options.locale);

	return (isNegative ? '-' : '') + numberString + ' ' + unit;

	return prefix + numberString + ' ' + unit;

> Convert bytes to a human readable string: `1337` → `1.34 kB`

Useful for displaying file sizes for humans.

*Note that it uses base-10 (e.g. kilobyte).

[Read about the difference between kilobyte and kibibyte.](https://web.archive.org/web/20150324153922/https://pacoup.com/2009/05/26/kb-kb-kib-whats-up-with-that/)*

const prettyBytes = require('pretty-bytes');

Include plus sign for positive numbers. If the difference is exactly zero a space character will be prepended instead for better alignment.

- If `true`: Localize the output using the system/browser locale.

- If `string`: Expects a [BCP 47 language tag](https://en.wikipedia.org/wiki/IETF_language_tag) (For example: `en`, `de`, …)

**Note:** Localization should generally work in browsers. Node.js needs to be [built](https://github.com/nodejs/node/wiki/Intl) with `full-icu` or `system-icu`. Alternatively, the [`full-icu`](https://github.com/unicode-org/full-icu-npm) module can be used to provide support at runtime.
