Verified usage

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

default

✓ import clsx from 'eslint-plugin-clsx'

✗ const clsx = require('eslint-plugin-clsx')

Default import is the plugin object. CJS require works but may lack type definitions.

configs.flat.recommended

✓ clsx.configs.flat.recommended

✗ clsx.configs.recommended

Use flat configs for ESLint 9+. Legacy configs available via plugin:clsx/recommended.

rules

✓ import { rules } from 'eslint-plugin-clsx'

✗ const rules = require('eslint-plugin-clsx').rules

Named export for accessing individual rule definitions.

Enable recommended rules with specific overrides in flat config format for ESLint 9+.

import clsx from 'eslint-plugin-clsx'; import { defineConfig } from 'eslint/config'; export default defineConfig({ plugins: { clsx }, rules: { 'clsx/no-redundant-clsx': 'error', 'clsx/forbid-array-expressions': 'warn', 'clsx/forbid-false-inside-object-expressions': 'warn', 'clsx/forbid-true-inside-object-expressions': 'warn', 'clsx/no-spreading': 'warn', 'clsx/prefer-merged-neighboring-elements': 'warn' } }); // Also works with flat config preset: // export default defineConfig(clsx.configs.flat.recommended);

Debug

Known issues

breakingv0.0.2 switched to TypeScript - existing CJS require may need update

fix

Update to >=0.0.2 and use TypeScript or ensure CJS compatibility

affects: <0.0.2

breakingv0.0.7 cleanup published files - may break import paths if using deep imports

fix

Use only top-level imports from 'eslint-plugin-clsx'

affects: <0.0.7

breakingv0.0.12 disallow extra properties in rule options - custom options may become invalid

fix

Stick to documented options schema

affects: <0.0.12

gotchaRequires ESLint 8, 9, or 10 as peer dependency - not compatible with other versions

fix

Install supported ESLint version

affects: *

deprecatedLegacy .eslintrc configs still work but flat configs are preferred for ESLint 9+

fix

Migrate to flat config using clsx.configs.flat.recommended

affects: >=0.0.11

Errors

Common errors & fixes

Error: Failed to load plugin 'clsx': Cannot find module 'eslint-plugin-clsx'

Missing installation or incorrect module resolution

fix

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

TypeError: Cannot read properties of undefined (reading 'recommended')

Attempting to access configs without proper import in flat config

fix

Use: import clsx from 'eslint-plugin-clsx'; then clsx.configs.flat.recommended

Configuration for rule 'clsx/no-redundant-clsx' is invalid: severity must be 'off', 'warn', or 'error'.

Invalid severity level in rule configuration

fix

Set rule to 'off', 'warn', or 'error' (not boolean or string like 'true')

ESLint configuration in .eslintrc.json is invalid: "extends": ["plugin:clsx/recommended"] is not a valid configuration.

Using legacy config syntax with ESLint 9+ flat config only project

fix

Switch to flat config format or ensure ESLint 8 compatibility
