## 🔌 API Integration Points
|
|
|
|
The frontend expects these backend endpoints:
|
|
|
|
1. **POST** `/api/upload` — Upload file or URL, returns `{ jobId }`
|
|
2. **GET** `/api/status/[jobId]` — Returns `AnalysisJob` object with current status/progress
|
|
3. **GET** `/api/review/[jobId]` — Returns `AlbumReview` object with full review data
|
|
|

|
|
|
|
## 🎮 User Flow
|
|
|
|
1. **Landing** (`/`) → User uploads file or pastes URL → Click "Analyze Now"
|
|
2. **Processing** (`/analyze/[jobId]`) → Shows progress + visualizer game, polls status every 2s
|
|
3. **Complete** → Auto-redirects to `/review/[jobId]`
|
|
4. **Review** (`/review/[jobId]`) → Shows beautiful review with ratings, scores, track cards
|
|
5. **Share** → User can copy URL or analyze another song

## 🚀 Next Steps for Backend
|
|
|
|
The frontend is complete and ready. The backend needs to implement:
|
|
|
|
1. `/api/upload` endpoint (file upload + URL handling)
|
|
2. `/api/status/[jobId]` endpoint (job status polling)
|
|
3. `/api/review/[jobId]` endpoint (return AlbumReview data)
|
|
4. Job processing queue (download → convert → transcribe → analyze → generate)
|
|
|
|
Once the backend is connected, the app will be fully functional!
