eslint-plugin-eslint-config

library2.0.0jsnpmunverified

ESLint plugin for linting ESLint configuration files, ensuring they are valid and consistent. Current stable version is 2.0.0, released January 2021, with a slow release cadence focused on bug fixes. Key differentiators: validates exported configs via execution, provides presets (recommended-rules, rc, all), and includes rules for deprecated/unknown rules and sorting. Requires ESLint >=5 and Node >=10, with peer dependency on eslint.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

eslint-plugin-eslint-config

✓ import configPlugin from 'eslint-plugin-eslint-config'; // or use through plugins in .eslintrc.js: plugins: ['eslint-config']

✗ const configPlugin = require('eslint-plugin-eslint-config'); // works but not needed if using plugins

Plugin is typically used via the plugins array in ESLint config, not directly imported in code.

rules

✓ import { rules } from 'eslint-plugin-eslint-config'; // then access individual rules via rules['no-deprecated-rules']

✗ const rules = require('eslint-plugin-eslint-config').rules; // common in CJS

The plugin exports a rules object; ESM import as above works, but CJS require is also common.

configs

✓ import { configs } from 'eslint-plugin-eslint-config'; // extend configs.recommendedRules or configs.rc in ESLint config

Available since v1.0.0; configs are exported as named objects matching preset names with camelCase.

Enables eslint-plugin-eslint-config in an ESLint config file, applying rules to ESLint config files.

// .eslintrc.js module.exports = { plugins: ['eslint-config'], overrides: [ { files: ['.eslintrc.js', 'my-config.js'], rules: { 'eslint-config/no-deprecated-rules': 'warn', 'eslint-config/no-invalid-config': 'error', 'eslint-config/no-unknown-rules': 'error', 'eslint-config/sort-rules': 'warn' } } ] };

Debug

Known issues

breakingDropped support for Node 8 in v2.0.0.

fix

Upgrade Node to v10 or higher.

affects: >=2.0.0

breakingUpdated @typescript-eslint/experimental-utils to v4 in v2.0.0, potentially breaking TypeScript users.

fix

Ensure @typescript-eslint packages are compatible; if using TypeScript, update to match.

affects: >=2.0.0

deprecatedThe 'all' preset may change in any release; not recommended for long-term consistency.

fix

Use 'recommended-rules' or 'rc' instead for stable base.

affects: *

gotchaRules execute the config files they lint; can trigger side effects. Should only be applied to specific files via overrides.

fix

Use overrides to limit rules to ESLint config files only.

affects: *

gotchaPlugin name must be 'eslint-config' (without 'eslint-plugin-') in plugins array, or 'eslint-config' as a string.

fix

Set plugins: ['eslint-config'] in your ESLint config.

affects: *
