Bytes utility

Utility to parse a string bytes (ex: 1TB) to bytes (1099511627776) and vice-versa.

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ npm install bytes

Usage

var bytes = require('bytes');

bytes(number｜string value, [options]): number｜string｜null

Default export function. Delegates to either bytes.format or bytes.parse based on the type of value.

Arguments

Name	Type	Description
value	number｜string	Number value to format or string value to parse
options	Object	Conversion options for format

Returns

Name	Type	Description
results	string｜number｜null	Return null upon error. Numeric value in bytes, or string value otherwise.

Example

bytes(1024);
// output: '1KB'

bytes('1KB');
// output: 1024

bytes.format(number value, [options]): string｜null

Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is rounded.

Arguments

Name	Type	Description
value	number	Value in bytes
options	Object	Conversion options

Options

Property	Type	Description
decimalPlaces	number｜null	Maximum number of decimal places to include in output. Default value to 2.
fixedDecimals	boolean｜null	Whether to always display the maximum number of decimal places. Default value to false
thousandsSeparator	string｜null	Example of values: ' ', ',' and '.'... Default value to ''.
unit	string｜null	The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to '' (which means auto detect).
unitSeparator	string｜null	Separator to use between number and unit. Default value to ''.

Returns

Name	Type	Description
results	string｜null	Return null upon error. String value otherwise.

Example

bytes.format(1024);
// output: '1KB'

bytes.format(1000);
// output: '1000B'

bytes.format(1000, {thousandsSeparator: ' '});
// output: '1 000B'

bytes.format(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'

bytes.format(1024, {unitSeparator: ' '});
// output: '1 KB'

bytes.parse(string｜number value): number｜null

Parse the string value into an integer in bytes. If no unit is given, or value is a number, it is assumed the value is in bytes.

Supported units and abbreviations are as follows and are case-insensitive:

• b for bytes
• kb for kilobytes
• mb for megabytes
• gb for gigabytes
• tb for terabytes
• pb for petabytes

The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.

Arguments

Name	Type	Description
value	string｜number	String to parse, or number in bytes.

Returns

Name	Type	Description
results	number｜null	Return null upon error. Value in bytes otherwise.

Example

bytes.parse('1KB');
// output: 1024

bytes.parse('1024');
// output: 1024

bytes.parse(1024);
// output: 1024
