[YagoBorba]

This implementation provides a complete scaffolding system supporting 8 technology stacks with automatic folder structure generation, package manager integration, and comprehensive documentation for future contributions.

📋 Description

This PR implements a comprehensive enhancement to StackCode's project scaffolding capabilities, expanding from a single Node.js + TypeScript stack to support 8 different technology stacks with complete project templates, intelligent package management, and modern development practices.

🎯 Key Features Implemented:

• 8 Technology Stacks: Node.js (JavaScript/TypeScript), React, Vue.js, Python (FastAPI), Java (Spring), Go (Gin), PHP (Laravel)
• Smart Package Management: Automatic detection and use of appropriate package managers (npm, pip, maven, go mod, composer)
• Complete Project Templates: Professional folder structures with best practices for each stack
• Modern Frontend Integration: TailwindCSS, modern build tools (Vite), and optimized configurations
• React Modernization: Updated to use JSX Transform (removed unnecessary React imports)
• Comprehensive Testing: Test templates and configurations for each technology
• Environment Configuration: Stack-specific .env files and configuration templates
• Extensive Documentation: Added comprehensive guides for contributing new stacks

🏗️ Architecture Improvements:

• Template System: Extensible .tpl file system with variable replacement ({{projectName}}, {{description}}, etc.)
• Type Safety: Updated TypeScript interfaces and type definitions across all packages
• CLI Enhancement: Interactive stack selection with user-friendly descriptions
• Build Integration: Enhanced build process to copy all templates to distribution

📋 Technical Implementation Details

Stack-Specific Features:

Frontend Stacks (React, Vue.js):

• ✅ Vite build system integration
• ✅ TailwindCSS styling framework
• ✅ TypeScript configuration
• ✅ Router setup (React Router, Vue Router)
• ✅ Component architecture
• ✅ Modern JSX Transform (React)

Backend Stacks (Node.js, Python, Java, Go, PHP):

• ✅ Framework-specific project structures
• ✅ API endpoint templates
• ✅ Health check implementations
• ✅ Testing configurations
• ✅ Environment management

Package Manager Integration:

// Intelligent package manager selection
if (stack === "python") {
  await runCommand("pip", ["install", "-e", "."], { cwd: projectPath });
} else if (stack === "java") {
  await runCommand("mvn", ["install"], { cwd: projectPath });
} else if (stack === "go") {
  await runCommand("go", ["mod", "tidy"], { cwd: projectPath });
} else if (stack === "php") {
  await runCommand("composer", ["install"], { cwd: projectPath });
} else {
  await runCommand("npm", ["install"], { cwd: projectPath });
}

📊 Statistics

• 74 files changed: 2,620 insertions, 19 deletions
• 56 new template files created
• 8 technology stacks fully implemented
• Multiple package managers supported
• Comprehensive documentation added

✅ Checklist

• My code follows the project's coding standards
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

🔄 Dependencies

• All existing dependencies maintained
• New dependencies added per stack requirements (React Router, Vue Router, etc.)
• No breaking changes to existing APIs

📚 Additional Notes

New Documentation Added:

• docs/STACKS.md: Comprehensive documentation of all supported stacks
• Enhanced CONTRIBUTING.md: Detailed guide for adding new technology stacks
• Template examples: Each stack includes complete project examples

Future Extensibility:

The architecture is designed to be easily extensible. Adding new stacks now requires:

1. Creating template files in packages/core/src/templates/new-stack/
2. Updating type definitions
3. Adding CLI options
4. Configuring package management
5. Testing thoroughly

This system establishes a solid foundation for supporting any technology stack in the future.
