Installation is done using the [`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): ```bash $ npm install bytes ``` ## Usage ```js var bytes = require('bytes'); ``` #### 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** ```js bytes(1024); // output: '1KB' bytes(1000); // output: '1000B' bytes(1000, {thousandsSeparator: ' '}); // output: '1 000B' bytes(1024 * 1.7, {decimalPlaces: 0}); // output: '2KB' bytes(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** ```js bytes('1KB'); // output: 1024 bytes('1024'); // output: 1024 bytes(1024); // output: 1KB ``` ## License [MIT](LICENSE) [coveralls-image]: https://badgen.net/coveralls/c/github/visionmedia/bytes.js/master [coveralls-url]: https://coveralls.io/r/visionmedia/bytes.js?branch=master [downloads-image]: https://badgen.net/npm/dm/bytes [downloads-url]: https://npmjs.org/package/bytes [npm-image]: https://badgen.net/npm/node/bytes [npm-url]: https://npmjs.org/package/bytes [travis-image]: https://badgen.net/travis/visionmedia/bytes.js/master [travis-url]: https://travis-ci.org/visionmedia/bytes.js bytes.js-3.1.0/index.js000066400000000000000000000066151342176573300147440ustar00rootroot00000000000000/*! * bytes * Copyright(c) 2012-2014 TJ Holowaychuk * Copyright(c) 2015 Jed Watson * MIT Licensed */ 'use strict'; /** * Module exports. * @public */ module.exports = bytes; module.exports.format = format; module.exports.parse = parse; /** * Module variables. * @private */ var formatThousandsRegExp = /\B(?=(\d{3})+(?!\d))/g; var formatDecimalsRegExp = /(?:\.0*|(\.[^0]+)0+)$/; var map = { b: 1, kb: 1 << 10, mb: 1 << 20, gb: 1 << 30, tb: Math.pow(1024, 4), pb: Math.pow(1024, 5), }; var parseRegExp = /^((-|\+)?(\d+(?:\.\d+)?)) *(kb|mb|gb|tb|pb)$/i; /** * Convert the given value in bytes into a string or parse to string to an integer in bytes. * * @param {string|number} value * @param {{ * case: [string], * decimalPlaces: [number] * fixedDecimals: [boolean] * thousandsSeparator: [string] * unitSeparator: [string] * }} [options] bytes options. * * @returns {string|number|null} */ function bytes(value, options) { if (typeof value === 'string') { return parse(value); } if (typeof value === 'number') { return format(value, options); } return null; } /** * Format the given value in bytes into a string. * * If the value is negative, it is kept as such.
