  env: {
    node: true
  },
  'extends': [
    'plugin:vue/recommended',
    '@vue/airbnb'
  ],
  rules: {
    'no-console': process.env.NODE_ENV === 'production' ? 'error' : 'off',
    'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off'
  },
  parserOptions: {
    parser: 'babel-eslint'
  }
};

What did you do?

export default {
  name: 'DarbībaShow',
};

What did you expect to happen?
linter should recognize this as a valid PascalCase

What actually happened?

...\show.vue
  13:9  error  Property name "DarbībaShow" is not PascalCase  vue/name-property-casing
