## Usage

If you did not already have `.eslintrc.js` configuration file in the root of your project create them.

Add the following to your `.eslintrc.js`:

```js
// .eslintrc.js
module.exports = {
  extends: ['@meludi/eslint-config-ts-base'],

  // Adjust it to your project
  // https://eslint.org/docs/latest/use/configure/language-options#specifying-environments
  env: {
    browser: true,
    es6: true,
    node: true,
  },

  parser: '@typescript-eslint/parser',

  // Adjust it to your project
  // https://typescript-eslint.io/architecture/parser/
  parserOptions: {
    project: ['./tsconfig.json', './tsconfig.eslint.json'],
    tsconfigRootDir: __dirname,
    sourceType: 'module',
    ecmaVersion: 'latest',
    ecmaFeatures: {
      jsx: true,
    },
  },

  // optional
  // https://www.npmjs.com/package/eslint-import-resolver-typescript
  settings: {
    'import/resolver': {
      typescript: {
        alwaysTryTypes: true,
        project: './tsconfig.json',
      },
    },
  },
};
```

### NPM script

Add the following script to your `package.json` for easy usage:

```json
"scripts": {
  "lint:js": "eslint './**/*.{js,ts}'",
  "lint:js:fix": "npm run lint:js -- --fix"
}
```

### Configuration

You can overwrite, extend and unset rules in your `.eslintrc.js`

> [Configuring ESLint](https://eslint.org/docs/user-guide/configuring)

Example `tsconfig.eslint.json` configuration file in the root of your project

```json
{
  "include": [
    // add all files in which you see
    // the "parserOptions.project" error
    // Example
    // ".eslintrc.cjs",
    // "commitlint.config.cjs",
    // "prettier.config.cjs"
  ]
}
```

## Recommendation

Use prettier to format your files: [@meludi/eslint-config-prettier](https://www.npmjs.com/package/@meludi/eslint-config-prettier)

Add the following config files to the root of your project:

- [.eslintignore](https://eslint.org/docs/latest/use/configure/ignore)
- [.editorconfig](https://editorconfig.org/)

### VS Code

Copy [.vscode.example](https://github.com/meludi/eslint-config/tree/master/packages/eslint-config-ts-base/.vscode.example) to the root of your project and rename it to `.vscode`.
