NiceStyle - Eslint config

A proposal of style and rules for javascript. This config is midly strict and you can overwrite or add rule if you want.

Install

npm install eslint-config-nicestyle

Usage

In your eslintrc.js:

{
    extends: "nicestyle",
    rules: {
        // you can overwrite rules here
    }
}

The package contains a .eslintrc.json file with all the rules so you can also modify it to create your own eslint configuration.
