pretty-bytes
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.
Install
$ npm install pretty-bytes
Usage
const prettyBytes = require('pretty-bytes');
prettyBytes(1337);
//=> '1.34 kB'
prettyBytes(100);
//=> '100 B'
// Display with units of bits
prettyBytes(1337, {bits: true});
//=> '1.34 kbit'
// Display file size differences
prettyBytes(42, {signed: true});
//=> '+42 B'
// Localized output using German locale
prettyBytes(1337, {locale: 'de'});
//=> '1,34 kB'
API
prettyBytes(number, options?)
number
Type: number
The number to format.
options
Type: object
signed
Type: boolean
Default: false
Include plus sign for positive numbers. If the difference is exactly zero a space character will be prepended instead for better alignment.
bits
Type: boolean
Default: false
Format the number as bits instead of bytes. This can be useful when, for example, referring to bit rate.
binary
Type: boolean
Default: false
Format the number using the Binary Prefix instead of the SI Prefix. This can be useful for presenting memory amounts. However, this should not be used for presenting file sizes.
locale
Type: boolean | string
Default: false (No localization)
Important: Only the number and decimal separator are localized. The unit title is not and will not be localized.
- If
true: Localize the output using the system/browser locale. - If
string: Expects a BCP 47 language tag (For example:en,de, …) - If
string[]: Expects a list of BCP 47 language tags (For example:en,de, …)
Note: Localization should generally work in browsers. Node.js needs to be built with full-icu or system-icu. Alternatively, the full-icu module can be used to provide support at runtime. Node.js 13 and later ships with ICU by default.
minimumFractionDigits
Type: number
Default: undefined
The minimum number of fraction digits to display.
If neither minimumFractionDigits or maximumFractionDigits are set, the default behavior is to round to 3 significant digits.
const prettyBytes = require('pretty-bytes');
// Show the number with at least 3 fractional digits
prettyBytes(1900, {minimumFractionDigits: 3});
//=> '1.900 kB'
prettyBytes(1900);
//=> '1.9 kB'
maximumFractionDigits
Type: number
Default: undefined
The maximum number of fraction digits to display.
If neither minimumFractionDigits or maximumFractionDigits are set, the default behavior is to round to 3 significant digits.
const prettyBytes = require('pretty-bytes');
// Show the number with at most 1 fractional digit
prettyBytes(1920, {maximumFractionDigits: 1});
//=> '1.9 kB'
prettyBytes(1920);
//=> '1.92 kB'
