json.dump appears to add extraneous spaces before newline characters. By specifying the separators option, we can remove these whitespaces, reducing the diff noise.

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.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(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:
bfor byteskbfor kilobytesmbfor megabytesgbfor gigabytestbfor terabytespbfor 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('1KB');
// output: 1024
bytes('1024');
// output: 1024
bytes(1024);
// output: 1KB
