### Custom Backend Endpoints

In addition to the standard Garage Admin API v2 endpoints, the Garage Web UI implements several custom backend endpoints for enhanced functionality:

| Endpoint | HTTP Method | Purpose | Status |
| -------- | ----------- | ------- | ------ |
| `/config` | GET | Get garage configuration | ✅ |
| `/auth/login` | POST | User authentication | ✅ |
| `/auth/logout` | POST | User logout | ✅ |
| `/auth/status` | GET | Authentication status | ✅ |
| `/buckets` | GET | Enhanced bucket listing with details | ✅ |
| `/browse/{bucket}` | GET | Browse bucket objects | ✅ |
| `/browse/{bucket}/{key...}` | GET | View/download object | ✅ |
| `/browse/{bucket}/{key...}` | PUT | Upload object | ✅ |
| `/browse/{bucket}/{key...}` | DELETE | Delete object/folder | ✅ |

### Upgrade Count

- **Total Standard v2 Endpoints Implemented**: 18

## Backend Compatibility

✅ **No Backend Modifications Required**:

- The backend uses a reverse proxy (`ProxyHandler`) to directly forward API requests to the Garage Admin API.
- All v2 API requests are automatically forwarded to the correct Garage Admin endpoints.
- No changes to the Go backend code were necessary.

## Build Verification

- No compilation errors.
- Docker build working properly.

✅ **Code Quality**:

- All ESLint errors and warnings have been resolved.
- Type definitions have been optimized (removed all `any` types).
- All React hooks follow proper dependency rules.
- Form controls are properly managed (controlled vs uncontrolled).
- All components have proper TypeScript interfaces.
- React component keys are properly assigned for list items.
- Input fields have appropriate `readOnly` props where needed.

2. ✅ **Functional Testing**: All upgraded features tested and working in production.
3. ✅ **Documentation Update**: Project documentation updated to reflect the use of the v2 API.
4. ✅ **Error Handling**: Error handling logic adjusted for the v2 API's response format.

## Future Enhancement Opportunities

1. **Additional v2 Features**: Implement newly available v2 API features such as:
   - Admin token management (`/v2/CreateAdminToken`, `/v2/ListAdminTokens`)
   - Enhanced node monitoring (`/v2/GetNodeInfo`, `/v2/GetNodeStatistics`)
   - Block management and repair tools (`/v2/GetBlockInfo`, `/v2/LaunchRepairOperation`)
2. **User Experience**: Continue improving the UI for mobile devices and add real-time updates.
3. **Monitoring Integration**: Enhanced Prometheus metrics visualization.
4. **Bulk Operations**: Support for bulk management of buckets and access keys.

## Risk Assessment

### ✅ Production Stable

- API path upgrade completed successfully.
- No compilation errors.
- Excellent backend compatibility.
- All features tested and working.

### ✅ Features Fully Operational

- All upgraded API endpoints working correctly.
- Error response handling optimized.
- API parameter formats fully compatible.

## Rollback Plan

To roll back to the v1 API if necessary:

1. Restore the API paths in all hook files.
2. Ensure the Garage server supports the v1 API.
3. Recompile and redeploy.
