The Challenge: Why GenshinWallCraft Was Built
Modern productivity tools often force users to switch between applications to manage tasks. GenshinWallCraft solves this by embedding actionable checklists directly into desktop wallpapers using:
- FastAPI’s asynchronous backend for high-concurrency generation
- React’s responsive frontend for seamless task management
- MinIO’s S3-compatible object storage for persistent wallpaper archives
Core Architecture & Technical Stack
Multi-Container Docker Deployment
The system runs as three coordinated services:
docker-compose.yml
services:
frontend:
image: nginx:alpine
ports:
- "5155:80"
backend:
build: ./backend
ports:
- "8009:8009"
minio:
image: minio/minio
ports:
- "9000:9000"
Image Generation Pipeline
- User submits tasks via React form
- FastAPI processes request with JWT validation
- Pillow composites text overlays on cached artwork
- MinIO stores final render with unique object ID
