This plugin provides rules for linting files that export configs meant for use with ESLint, to ensure that they're valid.

Installation

npm install --dev eslint eslint-plugin-eslint-config

Note: If you installed ESLint globally then you must also install eslint-plugin-eslint-config globally.

Usage

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

{
  "plugins": ["eslint-config"]
}

Then configure the rules you want to use for your config(s) using overrides:

{
  "overrides": [
    {
      "files": [".eslintrc.js", "react.js", "@typescript-eslint.js"],
      "rules": {
        "eslint-config/no-deprecated-rules": "warn"
      }
    }
  ]
}

The rules assume that the files they're linting are configs meant for ESLint.

Shareable configurations

This plugin provides three presets:

• recommended-rules
• rc
• all

The rc preset generally should be used by all projects, as it applies recommended rules to supported eslintrc files.

If a project contains other files that export eslint configs (such as an eslint config package), the recommended-rules preset can be used to apply the recommended rules to those files using overrides.

While the recommended-rules and rc presets only change in major versions, the all preset may change in any release and is thus unsuited for installations requiring long-term consistency.

Rules

| Rule | Description | Configurations | Fixable | | -------------------------------------------------------- | --------------------------------------------------- | ---------------- | ------------ | | no-deprecated-rules | Checks for usage of deprecated eslint rules | | | | no-invalid-config | Checks that the config exported by a file is valid | | | | no-unknown-rules | Ensures that all rules are known | | | | sort-rules | Ensures that rules are sorted in a consistent order | | |
