Codebase Index

A CLI tool for quick summarization of JavaScript/TypeScript codebases. Get an instant overview of all files and their exported symbols.

☢️ This codebase was almost entirely generated by LLM agent. I expect there is may be some issues. This is more or less poor man's quick and hacky solution to code summarization.

🚀 Quick Start

# Analyze current directory
npx codebase-index .

# Analyze specific directory
npx codebase-index my-project

# Use the simplified command
npx mindex .

Example output:

🔍 Mini-Index: Analyzing /Users/jin/dev/mini-index/test-samples

- advanced_python.py: VERSION, DEBUG, CONFIG_PATH, StatusEnum, UserData, authenticate_user, get_user_profile, async_fetch_data, DatabaseManager, static_utility_function, process_data, outer_function, result
- api/
  - route.ts: POST, GET
- components.jsx: ChatInterface, ErrorBoundary, Footer
- django_app.py: DEBUG, ALLOWED_HOSTS, DATABASE_URL, UserViewSet, ProductManager, dashboard_view, async_data_processor, calculate_price, format_currency
- sample.py: API_VERSION, DEBUG_MODE, get_user_data, process_payment, UserManager, PaymentProcessor
- types.ts: User, Message, DEFAULT_CONFIG, ChatState
- user.js: generateUserId, getCurrentUser, createUser, updateUserActivity

📦 Installation

# Global installation
npm install -g codebase-index

# Or use directly with npx
npx codebase-index .

✨ Features

• 📁 Directory Analysis: Recursively scans JavaScript/TypeScript projects
• 🔍 Symbol Extraction: Finds all exported functions, classes, types, and interfaces
• 🎯 Multi-Format Support: JavaScript (ES6/CommonJS), TypeScript, JSX/React
• 🌳 Tree Output: Clean, readable file structure with exported symbols
• ⚡ Fast & Lightweight: Quick analysis of entire codebases
• 🛡️ Error Handling: Graceful handling of parsing errors

🎯 Use Cases

• Code Reviews: Get a quick overview of what a project exports
• Documentation: Generate file structure for documentation
• Onboarding: Help new developers understand codebase structure
• Refactoring: Identify unused exports and dependencies
• Architecture: Visualize project organization

📋 Sample Output

🔍 Mini-Index: Analyzing /path/to/project

  - Footer.jsx: Footer
- lib/
  - types.ts: User, Message, ChatState
  - utils.js: generateId, formatDate
- models/

🎮 CLI Commands

# Main commands
npx codebase-index [directory]     # Full analysis
npx mindex [directory]         # Simplified command

# Examples
npx mindex .                   # Current directory
npx mindex src                 # Src folder only
npx mindex ../other-project    # Different project

📚 Programmatic API

const { EnhancedAnalyzer } = require('codebase-index');

const analyzer = new EnhancedAnalyzer();
const result = analyzer.analyzeProject('./my-project');
console.log(result);

🔧 Configuration

Mini-index automatically skips common directories:

• node_modules/
• .git/
• .next/
• dist/
• build/
