package.json に script 登録

    "scripts": {
    ...
    ...
    ...
        "stylelint": "stylelint ./resources/sass/app.scss ./resources/sass/app.scss",
        "stylelint-fix": "stylelint ./resources/sass/app.scss ./resources/sass/app.scss --fix",
    ...
    ...
    ...
    },
npm run stylelint

でルール違反表示

npm run stylelint-fix

でルール違反自動整形
