Release v0.2.0: Front-end Initialization and Project Re-structure to TypeScript

🚀 Major Changes

✨ Complete TypeScript Migration

• Converted entire codebase from JavaScript to TypeScript for enhanced type safety and developer experience

🏗️ Modular Architecture Refactor

• Restructured monolithic index.js into focused, maintainable modules:
  • src/cli.ts - Main CLI orchestration
  • src/utils/ - File operations, process management, and ASCII art utilities
  • src/frontend/setup.ts - Frontend initialization logic
  • src/project/scaffold.ts - Project structure creation
• Improved separation of concerns for easier maintenance and testing

🧪 Comprehensive Testing Suite

• Implemented integration tests for end-to-end frontend setup workflow
• Added error handling tests covering failure scenarios and recovery
• Configured Jest for TypeScript with proper test environment setup

🔧 Enhanced Development Experience

• New development scripts:
  • npm run dev - Run with ts-node for development
  • npm run build - Compile TypeScript to JavaScript
  • npm test:coverage - Generate detailed coverage reports
• Improved error handling with typed error messages and recovery mechanisms
• Better process management for external command execution (git, npm, yarn)

📋 Technical Improvements

Frontend Initialization

• Enhanced frontend setup validation with comprehensive error checking
• Improved directory reorganization logic with better cleanup on failures
• Robust dependency installation with fallback mechanisms
• Memory-aware configuration using w3b3d3v/create-polkadot-dapp template

🛠️ Breaking Changes

• Entry point changed from index.js to dist/index.js (compiled output)
• Node.js requirement updated to >= 20.0.0
• Development workflow now requires TypeScript compilation

📦 Dependencies

• Added TypeScript development dependencies (typescript, ts-node, ts-jest)
• Updated Jest configuration for TypeScript testing
• Maintained backward compatibility for all existing functionality
