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

## Installation

This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). 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(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**

\`\`\`js
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**

\`\`\`js
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**

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

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

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