Installation

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install eslint-plugin-eslint-plugin:

npm install eslint-plugin-eslint-plugin --save-dev

Usage

Here's an example ESLint configuration that:

• Sets sourceType to script for CJS plugins (most users) (use module for ESM/TypeScript)
• Enables the recommended configuration
• Enables an optional/non-recommended rule

{
    "parserOptions": {
        "sourceType": "script"
    },
    "extends": [
        "plugin:eslint-plugin/recommended"
    ],
    "rules": {
        "eslint-plugin/require-meta-docs-description": "error"
    }
}

Rules

• ✔️ if the rule belongs to the recommended configuration
• 🛠 if some problems reported by the rule are automatically fixable by the --fix command line option
• 💡 if some problems reported by the rule are manually fixable by editor suggestions

Presets

Semantic versioning policy

The list of recommended rules will only change in a major release of this plugin. However, new non-recommended rules might be added in a minor release of this plugin. Therefore, using the all, rules, and tests presets is not recommended for production use, because the addition of new rules in a minor release could break your build.

Preset usage

Presets are enabled by adding a line to the extends list in your config file. For example, to enable the recommended preset, use:

{
    "extends": [
        "plugin:eslint-plugin/recommended"
    ]
}

Or to apply linting only to the appropriate rule or test files:

{
    "overrides": [
        {
            "files": ["lib/rules/*.{js,ts}"],
            "extends": ["plugin:eslint-plugin/rules-recommended"]
        },
        {
            "files": ["tests/lib/rules/*.{js,ts}"],
            "extends": ["plugin:eslint-plugin/tests-recommended"]
        },
    ]
}
