## Overview

It contains frontend framework-agnostic base set of eslint rules. These rules help us to deliver consistent code quality across different frontend framework implementations supported by [JHipster](https://www.jhipster.tech).

### Extends

To keep consistent code quality across different implementations, [JHipster](https://www.jhipster.tech) shareable configuration extends the following set of recommended `ESLint` and `Typescript` configurations. JHipster uses `prettier` to keep consistent code formatting.

```
'eslint:recommended',
'plugin:@typescript-eslint/eslint-recommended',
'plugin:@typescript-eslint/recommended',
'plugin:@typescript-eslint/recommended-requiring-type-checking',
'prettier',
'prettier/@typescript-eslint',
'eslint-config-prettier'
```

### Rules

In addition to the recommended set of configurations, [JHipster](https://www.jhipster.tech) overrides following rules.

```
'@typescript-eslint/member-ordering': [
      'error',
      {
        default: [
          'static-field',
          'instance-field',
          'constructor',
          'static-method',
          'instance-method'
        ]
      }
    ],
    '@typescript-eslint/no-parameter-properties': [
      'warn',
      { allows: ['public', 'private', 'protected'] }
    ],
    '@typescript-eslint/no-unused-vars': [
      'warn',
      {
        vars: 'all',
        args: 'none',
        ignoreRestSiblings: false
      }
    ],
    '@typescript-eslint/explicit-member-accessibility': 'off',
    '@typescript-eslint/explicit-function-return-type': 'off',
    '@typescript-eslint/no-explicit-any': 'off',
    '@typescript-eslint/ban-types': 'off',
    '@typescript-eslint/interface-name-prefix': 'off',
    '@typescript-eslint/no-empty-function': 'off',
    '@typescript-eslint/unbound-method': 'off',
    'spaced-comment': ['warn', 'always'],
    'guard-for-in': 'error',
    'no-labels': 'error',
    'no-caller': 'error',
    'no-bitwise': 'error',
    'no-console': ['error', { allow: ['warn', 'error'] }],
    'no-new-wrappers': 'error',
    'no-eval': 'error',
    'no-shadow': 'error',
    'no-new': 'error',
    'no-var': 'error',
    radix: 'error',
    eqeqeq: ['error', 'always', { null: 'ignore' }],
    'prefer-const': 'error',
    'object-shorthand': ['error', 'always', { avoidExplicitReturnArrows: true }]
```
