    plugins: {
      'check-file': checkFile,
    },
    rules: {
      'check-file/no-index': 'error',
      'check-file/filename-blocklist': [
        'error',
        {
          '**/*.model.ts': '*.models.ts',
          '**/*.util.ts': '*.utils.ts',
        },
      ],
      'check-file/folder-match-with-fex': [
        'error',
        {
          '*.test.{js,jsx,ts,tsx}': '**/__tests__/',
          '*.styled.{jsx,tsx}': '**/pages/',
        },
      ],
      'check-file/filename-naming-convention': [

        {
          '**/*.{jsx,tsx}': 'CAMEL_CASE',
          '**/*.{js,ts}': 'KEBAB_CASE',
        },
      ],
      'check-file/folder-naming-convention': [
        'error',
        {
          'src/**/': 'CAMEL_CASE',
          'mocks/*/': 'KEBAB_CASE',

eslintrc

Add check-file to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": ["check-file"]
}

Then configure the rules you want to use under the rules section.

{
  "rules": {
    "check-file/no-index": "error",
    "check-file/filename-blocklist": [
      "error",
      {
        "**/*.model.ts": "*.models.ts",
        "**/*.util.ts": "*.utils.ts"
      }
    ],
    "check-file/folder-match-with-fex": [
      "error",
      {
        "*.test.{js,jsx,ts,tsx}": "**/__tests__/",
        "*.styled.{jsx,tsx}": "**/pages/"
      }
    ],
    "check-file/filename-naming-convention": [
      "error",
      {
        "**/*.{jsx,tsx}": "CAMEL_CASE",
        "**/*.{js,ts}": "KEBAB_CASE"
      }
    ],
    "check-file/folder-naming-convention": [
      "error",
      {
        "src/**/": "CAMEL_CASE",
        "mocks/*/": "KEBAB_CASE"
      }
    ]
