Verified usage

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

plugin

✓ import antfu from 'eslint-plugin-antfu'; export default [antfu.configs.recommended];

✗ const antfu = require('eslint-plugin-antfu');

ESM-only since v3.0.0; default export is the plugin object.

rules

✓ import { rules } from 'eslint-plugin-antfu';

Named export for rules object; also available via plugin.rules.

configs

✓ import { configs } from 'eslint-plugin-antfu';

✗ const { configs } = require('eslint-plugin-antfu');

ESM-only since v3.0.0; configs object contains 'recommended' and 'all'.

Shows how to import the plugin and apply its recommended config along with custom rule options in flat ESLint config.

// eslint.config.js import antfu from 'eslint-plugin-antfu'; export default [ antfu.configs.recommended, { rules: { 'antfu/consistent-chaining': ['warn', { allowLeadingPropertyAccess: false }], 'antfu/consistent-list-newline': ['error', { multiline: 'always' }], 'antfu/top-level-function': ['error'], 'antfu/no-top-level-await': ['error'], }, }, ];

Debug

Known issues

breakingv3.0.0 drops CJS support; require() will fail.

fix

Use ESM imports: import antfu from 'eslint-plugin-antfu'.

affects: >=3.0.0

gotchaRule 'consistent-chaining' option 'allowLeadingPropertyAccess' was renamed from 'allowFirstPropertyAccess' in v2.6.0.

fix

Use 'allowLeadingPropertyAccess' instead of deprecated 'allowFirstPropertyAccess'.

affects: >=2.6.0

gotchaThe plugin is opinionated and intended for use with antfu/eslint-config; mixing with other configs may cause conflicts.

fix

Use antfu/eslint-config as base or carefully merge configs.

affects: >=1.0.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module

Using CommonJS require() on an ESM-only package (v3+).

fix

Switch to ESM imports or downgrade to v2.x.

TypeError: antfu.configs is not iterable

Incorrectly using antfu.configs.recommended inside an array without spreading or without flat config.

fix

Ensure your ESLint config uses flat config format: export default [antfu.configs.recommended].

Rule 'antfu/consistent-chaining' has unknown option 'allowFirstPropertyAccess'.

Using deprecated option name from pre-2.6.0.

fix

Replace 'allowFirstPropertyAccess' with 'allowLeadingPropertyAccess'.
