- replace automatic SIM swap with manual activation process
- add eSIM information display with activation code and SSN
- include step-by-step manual activation guide and confirmation button
- update README and documentation to reflect new activation method
- add service time warning for Giffgaff's maintenance window
- remove outdated deployment options and simplify usage instructions
🔄 Complete Architecture Transformation:
- Migrated from PHP to Node.js backend
- Implemented Netlify Functions for serverless deployment
- Added Express.js server for local development
- Full compatibility with modern deployment platforms
🛠️ New Netlify Functions:
- giffgaff-mfa-challenge.js: Handles MFA email verification with proper headers
- giffgaff-mfa-validation.js: Processes MFA code validation
- verify-cookie.js: Cookie authentication converted from PHP to Node.js
✅ MFA 403 Error Resolution:
- Proper Origin and Referer headers in server-side requests
- Comprehensive error logging for debugging
- Timeout handling and robust error responses
- Should completely resolve MFA authentication issues
🍪 Enhanced Cookie Login:
- Full Node.js implementation replacing PHP dependency
- Works on all deployment platforms (Netlify, Vercel, traditional servers)
- Intelligent cookie parsing and validation
- Secure API calls with proper headers
�� Development Experience:
- package.json with all necessary dependencies
- Local development server (server.js)
- Environment configuration (env.example)
- Hot reload support with nodemon
🌐 Deployment Improvements:
- Netlify Functions integration
- Updated netlify.toml configuration
- Automatic dependency installation
- Zero-config deployment process
🎯 Key Benefits:
- ✅ Resolves MFA 403 errors through proper server-side handling
- ✅ Cookie login works on all platforms (no PHP dependency)
- ✅ Better error handling and logging
- ✅ Modern serverless architecture
- ✅ Improved development experience
- ✅ Full compatibility with static hosting platforms
📋 Technical Stack:
- Frontend: Pure HTML/CSS/JavaScript (unchanged)
- Backend: Node.js + Express.js (local) / Netlify Functions (production)
- Dependencies: axios, cors, helmet, morgan, dotenv
- Deployment: Netlify with automatic function deployment
This major upgrade modernizes the entire backend architecture while maintaining full frontend compatibility. The MFA 403 error should now be completely resolved through proper server-side request handling.
🔧 Features Added:
- simyo_static.html: Static demo version for Netlify deployment
- Public service integration: esim.cosr.eu.org
- Enhanced routing: /simyo-static for demo version
- Updated main page with version selection options
📝 Documentation Updates:
- README.md: Added public service links and version comparison
- Clear distinction between full-featured and static versions
- CORS solution recommendations updated
�� Deployment Strategy:
- Full version: Complete API functionality with proxy
- Static version: UI preview with CORS limitations
- Public service: Recommended for end users
This addresses the Netlify static deployment limitations while providing users with multiple access options.
