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.

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"]
}

Original Standard documentation shown below for reference:

Standard - ESLint Shareable Config

An ESLint Shareable Config for JavaScript Standard Style

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

Install

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:

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.

Looking for something easier than this?

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.
