@lilith/eslint-plugin-import-alias

ESLint plugin to enforce @/* import path aliases with automatic fixing.

v1.1.0: Zero-Config Aggressive Mode

Flags ALL ../ parent directory imports and auto-fixes to @/* aliases.

Installation

pnpm add -D @lilith/eslint-plugin-import-alias

Usage

ESLint Flat Config (ESLint 9+)

import importAliasPlugin from '@lilith/eslint-plugin-import-alias';

export default [
  {
    plugins: {
      'import-alias': importAliasPlugin,
    },
    rules: {
      'import-alias/prefer-alias': 'error', // Zero config!
    },
  },
];

Behavior

Flags and auto-fixes:

../entities/user.entity → @/entities/user.entity
../storage/storage.service → @/storage/storage.service
../../dto/create.dto → @/dto/create.dto
../../../config/app.config → @/config/app.config

Allows (unchanged):

./local-file - Same directory imports
@/entities - Already using @/* alias
@features/email/shared - Cross-component imports
@lilith/ui-primitives - Published packages

Examples

Before (violations)

import { UserEntity } from '../entities/user.entity';
import { UserService } from '../services/user.service';
import { StorageService } from '../storage/storage.service';
import { CreateUserDto } from '../../dto/create-user.dto';

After (auto-fixed with `eslint --fix`)

import { UserEntity } from '@/entities/user.entity';
import { UserService } from '@/services/user.service';
import { StorageService } from '@/storage/storage.service';
import { CreateUserDto } from '@/dto/create-user.dto';

Advanced Configuration (Optional)

The plugin works zero-config, but legacy options are available for backward compatibility:

'import-alias/prefer-alias': [
  'error',
  {
    architecturalDirs: ['entities', 'services'], // Ignored in v1.1.0
    multiLevelThreshold: 2, // Ignored in v1.1.0
  },
],

Note: In v1.1.0, all ../ imports are flagged regardless of config.
