Implement Server Architecture for App Preview Generator #10
Description
Overview
Transform the App Preview Generator into a full-stack application with server-side capabilities, App Store Connect integration, and advanced asset processing features.
Background
Currently operating as client-side only. Need server architecture for enterprise features, App Store Connect integration, multi-user collaboration, and automated asset optimization.
Core Server Components

- Multiple app localizations support
2. Asset Processing Pipeline
- Server-side image processing with exact App Store dimensions
- Automated JPEG conversion with quality optimization
- Dynamic template rendering
- AI-powered background removal
- CDN integration with smart caching
3. Multi-Language & Localization
- Translation API integrations (DeepL, Google Translate, OpenAI)
- Custom translation memory per project
- OCR-optimized text rendering for keyword extraction
- RTL language support
- Language-specific template variations
4. Project & Collaboration
- Cloud-based project storage with versioning
- Multi-user workspaces with RBAC
- Shared template library
- Real-time collaboration
- Revision history and rollback
5. Analytics & Optimization
- ASO keyword density analysis
- A/B testing framework
- App Store Analytics integration
- Competitor screenshot monitoring
- Conversion tracking
