## ⚙️ Configuration
|
||||||
|
|
||||||
|
**Environment Variables:**
|
||||||
|
```bash
|
||||||
|
PORT=3000 # Server port
|
||||||
|
ALLOWED_ORIGINS=* # CORS origins
|
||||||
|
API_KEY=your-secret-key # API key for callbacks
|
||||||
|
```
|
||||||
|
|
||||||
|
**Queue Settings (downloadQueue.js):**
|
||||||
|
```javascript
|
||||||
|
maxConcurrent: 3 // Max parallel downloads
|
||||||
|
cleanupInterval: 60 * 60 * 1000 // Cleanup every hour
|
||||||
|
jobRetention: 24 * 60 * 60 * 1000 // Keep jobs for 24h
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 🔐 Security
|
||||||
|
|
||||||
|
**API Key:**
|
||||||
|
- Sent in `X-API-Key` header on callbacks
|
||||||
|
- Backend should verify this key
|
||||||
|
- Set in `.env` file
|
||||||
|
|
||||||
|
**File Access:**
|
||||||
|
- Temp files in `/tmp` (auto-cleanup)
|
||||||
|
- Only accessible during processing
|
||||||
|
- Deleted after callback sent
|
||||||
|
|
||||||
|
**Cookies:**
|
||||||
|
- Read-only mount in Docker
|
||||||
|
- Permissions: 600
|
||||||
|
- Auto-refresh on expiry
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 🐛 Error Handling
|
||||||
|
|
||||||
|
**Download Failures:**
|
||||||
|
- Invalid URL → 400 Bad Request
|
||||||
|
- YouTube block → Retry with different client
|
||||||
|
- Network error → Retry 3 times
|
||||||
|
- Callback failure → Send error callback
|
||||||
|
|
||||||
|
**Job Failures:**
|
||||||
|
- Update status to `failed`
|
||||||
|
- Store error message
|
||||||
|
- Send failure callback to backend
|
||||||
|
- Keep job in history for 24h
|
||||||
|
|
||||||
|
**Cleanup:**
|
||||||
|
- Auto-delete temp files on success/failure
|
||||||
|
- Cleanup old jobs (>24h) hourly
|
||||||
|
- Graceful shutdown on SIGTERM
|
||||||
|
|
||||||
