Setup

1. Install the package: npm install --save-dev eslint-config-badboyku or yarn add --dev eslint-config-badboyku

2. Create a file named .eslintrc.js at the root and add the following:

   module.exports = {
     extends: ['badboyku'],
     rules: {},
   };

3. Add the following to your package.json scripts:

   "scripts": {
     "lint": "eslint \"./src/**/*.{js,jsx,ts,tsx}\"",
     "lint:fix": "eslint \"./src/**/*.{js,jsx,ts,tsx}\" --fix",
     "prettier": "prettier --check \"./src/**/*.{css,scss,json}\"",
     "prettier:fix": "prettier --write \"./src/**/*.{css,scss,json}\""
   },

Configure Rules (optional)

If you would like to configure a rule, then you can add to the rules object inside the .eslintrc.js file (from setup step 2).

Example:

rules: {
  'no-console': 'error',
},
