Usage

Install this package, with

$ npm i -D eslint           \
    eslint-config-noftalint \
    eslint-plugin-import    \
    eslint-plugin-node      \
    eslint-plugin-unicorn

Add noftalint to your .eslintrc.js: extends: ['noftalint']

Use with TypeScript

noftalint also contains TypeScript rules, from @typescript-eslint/eslint-plugin! They are not included by default, so you need to configure some things first.

Run the following command to install the required dependencies

$ npm i -D typescript         \
    @typescript-eslint/parser \
    @typescript-eslint/eslint-plugin

Update your .eslintrc.js configuration with the following values:

module.exports = {
  extends: ['noftalint/typescript'],
  parser: '@typescript-eslint/parser',
  plugins: ['@typescript-eslint'],
  ...
};

Create a file named tsconfig.eslint.json, at the same level as your tsconfig.json.
Add this inside your tsconfig.eslint.json. The includes property must be all the files you want to lint, including JS files.

{
  "extends": "./tsconfig.json",
  "include": [
    "src/**/*.ts",
    ".eslintrc.js"
  ]
}

If you want to use custom TypeScript's path aliases, you will have to follow these steps:

$ npm install --save-dev eslint-import-resolver-typescript

Update your .eslintrc.js by disabling node/no-missing-import as it does not support TypeScript's path aliases; and by updating the settings for import/resolver.

module.exports = {
  ...
  rules: {
    ...
    // It cannot resolve TypeScript's path aliases. See https://github.com/mysticatea/eslint-plugin-node/issues/233
    'node/no-missing-import': 'off',
  },
  settings: {
    ...
    'import/resolver': {
      typescript: {
        alwaysTryTypes: true,
      },
    },
  },
};

If you use the shebang notation inside your project, you will need to modify the node/shebang rule in your .eslintrc.js:

module.exports = {
  ...
  rules: {
    ...
    'node/shebang': ['error', {
      convertPath: {
        // Change your main file and your destination file to what you want
        'src/main.ts': ['^src/main.ts$', 'build/main.js'],
      },
    }],
  }
}
