🔍 ESLint Plugin: suggest-members

Production-ready ESLint plugin that intelligently suggests corrections for typos in TypeScript/JavaScript code. Built with Functional Core, Imperative Shell architecture for maximum reliability and performance.

✨ Key Features

• 🎯 Smart Suggestions: Advanced similarity algorithms (Levenshtein + context analysis)
• 🚀 TypeScript Integration: Full type-aware analysis with graceful fallbacks
• ⚡ High Performance: Optimized for large codebases with caching
• 🛡️ Zero Breaking: Never interrupts your linting workflow
• 🧪 100% Tested: Comprehensive test coverage with property-based testing
• 📦 ESM Ready: Modern ES modules with TypeScript support

🎯 Real-World Examples

Export Suggestions (suggest-exports)

// ❌ Typo in React hook import
import { useStae, useEffect } from 'react'
//         ~~~~~~~ 
// ✅ ESLint Error: Module 'react' does not export 'useStae'. Did you mean:
//    - useState
//    - useRef  
//    - useMemo
//    - useCallback

Member Suggestions (suggest-members)

// ❌ Typo in localStorage method
localStorage.get1Item('token')
//           ~~~~~~~~
// ✅ ESLint Error: Property "get1Item" does not exist. Did you mean:
//    - getItem(key: string): string | null
//    - setItem(key: string, value: string)  
//    - removeItem(key: string)
//    - clear(): void

Module Path Suggestions (suggest-module-paths)

// ❌ Typo in file path
import styles from './HamsterKo1mbatPage.css'
//                  ~~~~~~~~~~~~~~~~~~~~~~
// ✅ ESLint Error: Cannot find module "./HamsterKo1mbatPage.css". Did you mean:
//    - ./HamsterKombatPage.css
//    - ./HamsterKombatPage.tsx
//    - ./HamsterKombatPage
//    - ../ThemeParamsPage.css

Import Suggestions (suggest-imports)

// ❌ Typo in named import
import { saveRe1f } from './hooks'
//       ~~~~~~~~
// ✅ ESLint Error: Variable "saveRe1f" is not defined. Did you mean:
//    - saveRef
//    - saveState
//    - useRef
//    - useState

⚙️ Configuration

ESLint v9+ (Flat Config)

// eslint.config.js
import suggestMembers from "@ton-ai-core/eslint-plugin-suggest-members";

export default [
  {
    files: ["**/*.{ts,tsx,js,jsx}"],
    plugins: { 
      "suggest-members": suggestMembers 
    },
    rules: {
      "suggest-members/suggest-exports": "error",
      "suggest-members/suggest-imports": "error", 
      "suggest-members/suggest-members": "error",
      "suggest-members/suggest-module-paths": "error"
    }
  }
];

ESLint v8 (Legacy Config)

{
  "plugins": ["@ton-ai-core/suggest-members"],
  "rules": {
    "@ton-ai-core/suggest-members/suggest-exports": "error",
    "@ton-ai-core/suggest-members/suggest-imports": "error",
    "@ton-ai-core/suggest-members/suggest-members": "error", 
    "@ton-ai-core/suggest-members/suggest-module-paths": "error"
  }
}

Recommended Configuration (Simplified Setup)

Instead of manually configuring each rule, you can use our recommended configuration that automatically enables all rules:

ESLint v9+ (Flat Config)

// eslint.config.js
import suggestMembers from "@ton-ai-core/eslint-plugin-suggest-members";

export default [
  {
    files: ["**/*.{ts,tsx,js,jsx}"],
    plugins: { 
      "suggest-members": suggestMembers 
    },
    ...suggestMembers.configs.recommended // Automatically enables all rules
  }
];

ESLint v8 (Legacy Config)

{
  "extends": ["plugin:@ton-ai-core/suggest-members/recommended"],
  "plugins": ["@ton-ai-core/suggest-members"]
}

TypeScript Integration

// tsconfig.json - Required for full functionality
{
  "compilerOptions": {
    "strict": true,
    "noImplicitAny": true
  },
  "include": ["src/**/*"]
}

🔧 Rules Reference

| Rule | Description | TypeScript Required | |------|-------------|-------------------| | suggest-exports | Suggests corrections for non-existent exports | ✅ Recommended | | suggest-imports | Suggests corrections for non-existent imports | ✅ Recommended |
| suggest-members | Suggests corrections for object properties/methods | ✅ Required | | suggest-module-paths | Suggests corrections for module paths | ❌ Filesystem only |

🚀 Performance & Reliability

Built for Scale

• ⚡ Fast: < 100ms analysis per file
• 🧠 Smart Caching: Reuses TypeScript program instances
• 🛡️ Graceful Fallbacks: Works without TypeScript service
• 📊 Memory Efficient: Optimized for large codebases

Architecture Highlights

// Functional Core: Pure functions only
const calculateSimilarity = (target: string, candidates: readonly string[]): SimilarityScore[]

// Imperative Shell: Controlled effects  
const validateWithTypeScript = Effect.gen(function* (_) {
  const typeChecker = yield* _(TypeScriptService)
  const members = yield* _(getTypeMembers(type))
  return createSuggestions(members)
})
