Usage

npm install --save-dev eslint-config-excellence

Then extend excellence in your .eslintrc:

{
    "extends": "excellence"
}

You might want to use .eslintrc.js instead, since the .eslintrc was deprecated!

Common Rules

You might want to change some rules, that are controversial and often disputed inside the JS community. The defaults that excellence applies are listed here.

{
    'jsx-quotes': [ 2, 'prefer-single' ], // prfer-single or prefer-double
    'quotes': [ 2, 'single' ], // single or double
    'semi': [ 2, 'always' ] // always or never
}

Advises

It is probably a good idea to use Editorconfig alongside ESLint. Check out their website.
