Standard Trailing Commas

A fork of eslint-config-standard which enforces the use of trailing, aka dangling, commas in object literals & arrays that span multiple lines.

Why would you want to use this? From the eslint documentation page for this rule:

> Trailing commas simplify adding and removing items to objects and arrays, since only the lines you are modifying
> must be touched. Another argument in favor of trailing commas is that it improves the clarity of diffs when an item
> is added or removed from an object or array

Instructions

First, install the eslint config & required plugins.

``bash
npm i -D eslint-config-standard-trailing-commas eslint-plugin-standard eslint-plugin-promise
`

Then, add this to your .eslintrc.json file:

`
{
"extends": "standard-trailing-commas"
}
`

Or this, if using React:

`
{
"extends": ["standard-trailing-commas", "standard-react"]
}
`

#### An ESLint Shareable Config for JavaScript Standard Style

This module is for advanced users. You probably want to use standard instead :)


Install

`bash
npm install eslint-config-standard
`

Usage

Shareable configs are designed to work with the extends feature of .eslintrc files.
You can learn more about
Shareable Configs on the
official ESLint website.

To use the JavaScript Standard Style shareable config, first run this:

`bash
npm install eslint-config-standard eslint-plugin-standard eslint-plugin-promise
`

Then, add this to your .eslintrc file:

`
{
"extends": "standard"
}
`

Note: We omitted the eslint-config- prefix since it is automatically assumed by ESLint.

You can override settings from the shareable config by adding them directly into your
.eslintrc file.

$3

The easiest way to use JavaScript Standard Style to check your code is to use the
standard package. This comes with a global
Node command line program (standard) that you can run or add to your npm test script
to quickly check your style.

Badge

Use this in one of your projects? Include one of these badges in your readme to
let people know that your code is using the standard style.
