Create a file named
.eslintrc.jsat the root and add the following:module.exports = { extends: ['badboyku'], rules: {}, };
-
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}\"" },
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).

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