# Flask Backend Auto-Detection Implementation
|
||||
|
||||
## Summary
|
||||
|
||||
Implemented automatic detection and fallback between Flask backend (SQLite) and IndexedDB storage based on Docker environment variables. The system intelligently selects the appropriate storage backend at runtime without requiring code changes or rebuilds.
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Storage Adapter System (`src/lib/storage-adapter.ts`)
|
||||
|
||||
Created a new unified storage adapter with three implementations:
|
||||
|
||||
- **FlaskBackendAdapter**: HTTP client for Flask backend API
|
||||
- Health check with 3-second timeout
|
||||
- Full CRUD operations via REST API
|
||||
- Export/import capabilities
|
||||
- Statistics endpoint integration
|
||||
|
||||
- **IndexedDBAdapter**: Browser-side storage
|
||||
- Standard IndexedDB operations
|
||||
- Async/await interface
|
||||
- Object store management
|
||||
|
||||
- **AutoStorageAdapter**: Smart detection and routing
|
||||
- Checks environment variables (`USE_FLASK_BACKEND`, `VITE_USE_FLASK_BACKEND`)
|
||||
- Tests Flask backend availability via `/health` endpoint
|
||||
- Falls back to IndexedDB if Flask unavailable
|
||||
- Migration tools between backends
|
||||
|
||||
### 2. Updated Storage Library (`src/lib/storage.ts`)
|
||||
|
||||
Simplified the storage interface to use the new adapter:
|
||||
- Removed complex dual-storage logic
|
||||
- Clean async/await API
|
||||
- Added `getBackendType()` to check current backend
|
||||
- Migration methods for switching backends
|
||||
|
||||
### 3. Storage Management UI (`src/components/StorageSettings.tsx`)
|
||||
|
||||
Complete rewrite with:
|
||||
- Backend type indicator (Flask vs IndexedDB)
|
||||
- Storage statistics display
|
||||
- Migration controls with URL input
|
||||
- Clear backend-specific actions
|
||||
- Real-time status updates
|
||||
|
||||
### 4. Docker Configuration
|
||||
|
||||
#### Environment Variables (`.env.example`)
|
||||
```bash
|
||||
VITE_USE_FLASK_BACKEND=false
|
||||
VITE_FLASK_BACKEND_URL=http://localhost:5001
|
||||
```
|
||||
|
||||
#### Docker Compose (`docker-compose.yml`)
|
||||
```yaml
|
||||
frontend:
|
||||
environment:
|
||||
- USE_FLASK_BACKEND=true
|
||||
- FLASK_BACKEND_URL=http://backend:5001
|
||||
depends_on:
|
||||
- backend
|
||||
```
|
||||
|
||||
#### Entrypoint Script (`docker-entrypoint.sh`)
|
||||
- Injects runtime environment variables into HTML
|
||||
- Creates `runtime-config.js` with configuration
|
||||
- No rebuild required for config changes
|
||||
|
||||
#### Updated HTML (`index.html`)
|
||||
- Loads `runtime-config.js` before app initialization
|
||||
- Environment variables available as `window.USE_FLASK_BACKEND` and `window.FLASK_BACKEND_URL`
|
||||
|
||||
### 5. Documentation
|
||||
|
||||
Created `docs/STORAGE_BACKEND.md` covering:
|
||||
- Storage backend options and tradeoffs
|
||||
- Configuration for development and production
|
||||
- Docker deployment examples
|
||||
- Migration procedures
|
||||
- API reference
|
||||
- Troubleshooting guide
|
||||
- Performance considerations
|
||||
- Security notes
|
||||
|
||||
Updated `README.md` with:
|
||||
- Storage backend configuration section
|
||||
- Quick start for both backends
|
||||
- Migration information
|
||||
|
||||
## How It Works
|
||||
|
||||
### Automatic Detection Flow
|
||||
|
||||
1. **App Starts**
|
||||
```
|
||||
StorageAdapter initializes
|
||||
↓
|
||||
Check USE_FLASK_BACKEND environment variable
|
||||
↓
|
||||
If true → Test Flask backend availability
|
||||
↓
|
||||
Success → Use FlaskBackendAdapter
|
||||
↓
|
||||
Failure → Fallback to IndexedDBAdapter (with warning)
|
||||
```
|
||||
|
||||
2. **Runtime Configuration**
|
||||
```
|
||||
Docker container starts
|
||||
↓
|
||||
docker-entrypoint.sh runs
|
||||
↓
|
||||
Inject environment variables into runtime-config.js
|
||||
↓
|
||||
HTML loads runtime-config.js
|
||||
↓
|
||||
Variables available to StorageAdapter
|
||||
```
|
||||
|
||||
3. **Storage Operations**
|
||||
```
|
||||
App calls storage.get('key')
|
||||
↓
|
||||
AutoStorageAdapter routes to active backend
|
||||
↓
|
||||
Flask: HTTP request to /api/storage/key
|
||||
IndexedDB: IndexedDB transaction
|
||||
↓
|
||||
Return data to app
|
||||
```
|
||||
|
||||
### Environment Variable Priority
|
||||
|
||||
1. Docker runtime: `window.USE_FLASK_BACKEND` (set by entrypoint script)
|
||||
2. Vite environment: `import.meta.env.VITE_USE_FLASK_BACKEND`
|
||||
3. Default: `false` (use IndexedDB)
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Development with IndexedDB (Default)
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
```
|
||||
|
||||
No configuration needed. All data stored in browser.
|
||||
|
||||
### Development with Flask Backend
|
||||
|
||||
```bash
|
||||
# Terminal 1: Start Flask backend
|
||||
cd backend
|
||||
python app.py
|
||||
|
||||
# Terminal 2: Configure and start frontend
|
||||
echo "VITE_USE_FLASK_BACKEND=true" > .env
|
||||
echo "VITE_FLASK_BACKEND_URL=http://localhost:5001" >> .env
|
||||
npm run dev
|
||||
```
|
||||
|
||||
### Production with Docker
|
||||
|
||||
```bash
|
||||
# Start both services
|
||||
docker-compose up -d
|
||||
|
||||
# Environment variables in docker-compose.yml:
|
||||
# USE_FLASK_BACKEND=true
|
||||
# FLASK_BACKEND_URL=http://backend:5001
|
||||
```
|
||||
|
||||
### Migration Between Backends
|
||||
|
||||
```typescript
|
||||
import { storage } from '@/lib/storage'
|
||||
|
||||
// Check current backend
|
||||
const backend = storage.getBackendType() // 'flask' or 'indexeddb'
|
||||
|
||||
// Migrate IndexedDB → Flask
|
||||
const count = await storage.migrateToFlask('http://localhost:5001')
|
||||
console.log(`Migrated ${count} items`)
|
||||
// Page reloads to use Flask backend
|
||||
|
||||
// Migrate Flask → IndexedDB
|
||||
const count = await storage.migrateToIndexedDB()
|
||||
console.log(`Migrated ${count} items`)
|
||||
// Page reloads to use IndexedDB
|
||||
```
|
||||
|
||||
## Flask Backend API
|
||||
|
||||
All endpoints work consistently regardless of storage backend:
|
||||
|
||||
```bash
|
||||
# Health check
|
||||
GET /health
|
||||
|
||||
# Storage operations
|
||||
GET /api/storage/keys # List all keys
|
||||
GET /api/storage/<key> # Get value
|
||||
PUT /api/storage/<key> # Set value
|
||||
DELETE /api/storage/<key> # Delete key
|
||||
POST /api/storage/clear # Clear all
|
||||
GET /api/storage/export # Export JSON
|
||||
POST /api/storage/import # Import JSON
|
||||
GET /api/storage/stats # Statistics
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
### For Development
|
||||
- **No server required**: Default IndexedDB works out of the box
|
||||
- **Fast iteration**: Browser storage with instant updates
|
||||
- **Offline capable**: Work without internet connection
|
||||
- **Easy debugging**: Chrome DevTools IndexedDB inspector
|
||||
|
||||
### For Production
|
||||
- **Persistent storage**: Data survives browser clears
|
||||
- **Multi-device**: Access data from any browser
|
||||
- **Backup ready**: SQLite file can be backed up
|
||||
- **Scalable**: Easy to migrate to PostgreSQL later
|
||||
|
||||
### For Deployment
|
||||
- **Zero configuration**: Works with or without backend
|
||||
- **Flexible**: Change backend without rebuilding image
|
||||
- **Graceful fallback**: If backend fails, uses IndexedDB
|
||||
- **Docker-friendly**: Environment variables configure everything
|
||||
|
||||
## Testing
|
||||
|
||||
The implementation includes:
|
||||
|
||||
1. **Automatic fallback testing**: If Flask backend unavailable, falls back to IndexedDB with console warning
|
||||
2. **Health check**: 3-second timeout prevents hanging
|
||||
3. **Migration validation**: Confirms data integrity during migration
|
||||
4. **Backend detection**: Logs selected backend to console for debugging
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
Potential improvements identified:
|
||||
|
||||
1. **PostgreSQL/MySQL support**: Add database adapters
|
||||
2. **Real-time sync**: WebSocket for live updates
|
||||
3. **Authentication**: Add user auth to Flask backend
|
||||
4. **Encryption**: Encrypt sensitive data at rest
|
||||
5. **Caching**: Add Redis layer for performance
|
||||
6. **Multi-tenancy**: Support multiple users/teams
|
||||
|
||||
## Breaking Changes
|
||||
|
||||
None. The implementation is fully backward compatible:
|
||||
- Existing IndexedDB data continues to work
|
||||
- No API changes required
|
||||
- Optional feature that can be ignored
|
||||
|
||||
## Files Modified

||||
|
||||
- `src/lib/storage-adapter.ts` (NEW)
|
||||
- `src/lib/storage.ts` (UPDATED)
|
||||

# Storage Backend Configuration
|
||||
|
||||
CodeForge supports two storage backends that can be configured at deployment time:
|
||||
|
||||
## Storage Options
|
||||
|
||||
### 1. IndexedDB (Default)
|
||||
- **Type**: Client-side browser storage
|
||||
- **Pros**: No server required, works offline, fast
|
||||
- **Cons**: Data is stored in browser, not shared across devices
|
||||
- **Use Case**: Development, single-user scenarios, offline work
|
||||
|
||||
### 2. Flask Backend with SQLite
|
||||
- **Type**: Server-side persistent storage
|
||||
- **Pros**: Data persists across browsers, shareable, more reliable
|
||||
- **Cons**: Requires running backend server
|
||||
- **Use Case**: Production deployments, multi-device access, team collaboration
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
The storage backend is configured using environment variables:
|
||||
|
||||
#### For Development (.env file)
|
||||
```bash
|
||||
# Use Flask backend instead of IndexedDB
|
||||
VITE_USE_FLASK_BACKEND=true
|
||||
|
||||
# Flask backend URL
|
||||
VITE_FLASK_BACKEND_URL=http://localhost:5001
|
||||
```
|
||||
|
||||
#### For Docker Deployment
|
||||
```yaml
|
||||
services:
|
||||
frontend:
|
||||
environment:
|
||||
- USE_FLASK_BACKEND=true
|
||||
- FLASK_BACKEND_URL=http://backend:5001
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Running with IndexedDB (Default)
|
||||
|
||||
No configuration needed. Just start the app:
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
```
|
||||
|
||||
All data will be stored in your browser's IndexedDB.
|
||||
|
||||
### Running with Flask Backend
|
||||
|
||||
#### Option 1: Using Docker Compose (Recommended)
|
||||
|
||||
```bash
|
||||
# Start both frontend and backend
|
||||
docker-compose up -d
|
||||
|
||||
# The frontend will automatically connect to the backend
|
||||
# Data is stored in a Docker volume for persistence
|
||||
```
|
||||
|
||||
#### Option 2: Manual Setup
|
||||
|
||||
1. Start the Flask backend:
|
||||
```bash
|
||||
cd backend
|
||||
python -m venv venv
|
||||
source venv/bin/activate # On Windows: venv\Scripts\activate
|
||||
pip install -r requirements.txt
|
||||
python app.py
|
||||
```
|
||||
|
||||
2. Configure the frontend:
|
||||
```bash
|
||||
# Create .env file
|
||||
echo "VITE_USE_FLASK_BACKEND=true" > .env
|
||||
echo "VITE_FLASK_BACKEND_URL=http://localhost:5001" >> .env
|
||||
|
||||
# Start the frontend
|
||||
npm run dev
|
||||
```
|
||||
|
||||
## Automatic Detection and Fallback
|
||||
|
||||
The storage adapter automatically:
|
||||
1. Checks if Flask backend is configured (`USE_FLASK_BACKEND=true` or `VITE_USE_FLASK_BACKEND=true`)
|
||||
2. If configured, tests backend availability by calling `/health` endpoint
|
||||
3. Falls back to IndexedDB if backend is unavailable
|
||||
4. Logs the selected backend to console
|
||||
|
||||
## Migration Between Backends
|
||||
|
||||
You can migrate data between backends using the Storage Management UI:
|
||||
|
||||
1. Navigate to **Settings → Storage Management**
|
||||
2. View current backend type
|
||||
3. Use migration tools to:
|
||||
- **Migrate to Flask**: Copies all IndexedDB data to Flask backend
|
||||
- **Migrate to IndexedDB**: Copies all Flask data to browser storage
|
||||
|
||||
### Migration Process
|
||||
|
||||
```typescript
|
||||
import { storage } from '@/lib/storage'
|
||||
|
||||
// Migrate from IndexedDB to Flask
|
||||
const count = await storage.migrateToFlask('http://localhost:5001')
|
||||
console.log(`Migrated ${count} items`)
|
||||
|
||||
// Migrate from Flask to IndexedDB
|
||||
const count = await storage.migrateToIndexedDB()
|
||||
console.log(`Migrated ${count} items`)
|
||||
```
|
||||
|
||||
## Storage API
|
||||
|
||||
The storage API is consistent regardless of backend:
|
||||
|
||||
```typescript
|
||||
import { storage } from '@/lib/storage'
|
||||
|
||||
// Get backend type
|
||||
const backend = storage.getBackendType() // 'flask' | 'indexeddb'
|
||||
|
||||
// Store data
|
||||
await storage.set('my-key', { foo: 'bar' })
|
||||
|
||||
// Retrieve data
|
||||
const data = await storage.get('my-key')
|
||||
|
||||
// Delete data
|
||||
await storage.delete('my-key')
|
||||
|
||||
// List all keys
|
||||
const keys = await storage.keys()
|
||||
|
||||
// Clear all data
|
||||
await storage.clear()
|
||||
```
|
||||
|
||||
## Flask Backend API
|
||||
|
||||
The Flask backend exposes a REST API for storage operations:
|
||||
|
||||
### Endpoints
|
||||
|
||||
- `GET /health` - Health check
|
||||
- `GET /api/storage/keys` - List all keys
|
||||
- `GET /api/storage/<key>` - Get value for key
|
||||
- `PUT /api/storage/<key>` - Set value for key
|
||||
- `DELETE /api/storage/<key>` - Delete key
|
||||
- `POST /api/storage/clear` - Clear all data
|
||||
- `GET /api/storage/export` - Export all data as JSON
|
||||
- `POST /api/storage/import` - Import JSON data
|
||||
- `GET /api/storage/stats` - Get storage statistics
|
||||
|
||||
### Example Requests
|
||||
|
||||
```bash
|
||||
# Health check
|
||||
curl http://localhost:5001/health
|
||||
|
||||
# Set a value
|
||||
curl -X PUT http://localhost:5001/api/storage/my-key \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"value": {"foo": "bar"}}'
|
||||
|
||||
# Get a value

|

|

## Deployment Examples
|
||||
|
||||
### Docker Compose (Production)
|
||||
|
||||
```yaml
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
frontend:
|
||||
image: codeforge:latest
|
||||
environment:
|
||||
- USE_FLASK_BACKEND=true
|
||||
- FLASK_BACKEND_URL=http://backend:5001
|
||||
depends_on:
|
||||
- backend
|
||||
|
||||
backend:
|
||||
image: codeforge-backend:latest
|
||||
volumes:
|
||||
- ./data:/data
|
||||
environment:
|
||||
- DATABASE_PATH=/data/codeforge.db
|
||||
```
|
||||
|
||||
### Kubernetes
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: codeforge-config
|
||||
data:
|
||||
USE_FLASK_BACKEND: "true"
|
||||
FLASK_BACKEND_URL: "http://codeforge-backend:5001"
|
||||
|
||||
---
|
||||
apiVersion: apps/v1
|
||||
kind: Deployment
|
||||
metadata:
|
||||
name: codeforge-frontend
|
||||
spec:
|
||||
template:
|
||||
spec:
|
||||
containers:
|
||||
- name: frontend
|
||||
envFrom:
|
||||
- configMapRef:
|
||||
name: codeforge-config
|
||||
```
|
||||
|
||||
### Standalone (IndexedDB Only)
|
||||
|
||||
```dockerfile
|
||||
FROM codeforge:latest
|
||||
# No environment variables needed
|
||||
# IndexedDB is used by default
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Backend Not Detected
|
||||
|
||||
If the Flask backend is configured but not being used:
|
||||
|
||||
1. Check backend is running: `curl http://localhost:5001/health`
|
||||
2. Check browser console for connection errors
|
||||
3. Verify `USE_FLASK_BACKEND` environment variable is set
|
||||
4. Check CORS settings if frontend and backend are on different domains
|
||||
|
||||
### Migration Fails
|
||||
|
||||
If migration between backends fails:
|
||||
|
||||
1. Ensure both source and destination are accessible
|
||||
2. Check browser console for detailed error messages
|
||||
3. Try exporting data manually and importing to new backend
|
||||
4. Check available storage space
|
||||
|
||||
### Data Loss Prevention
|
||||
|
||||
- Always backup data before migration
|
||||
- Use the export API to create backups: `GET /api/storage/export`
|
||||
- Keep both backends running during migration
|
||||
- Test migration with sample data first
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### IndexedDB
|
||||
- **Read**: ~1-5ms per operation
|
||||
- **Write**: ~5-20ms per operation
|
||||
- **Limit**: ~50MB-1GB (browser dependent)
|
||||
|
||||
### Flask Backend
|
||||
- **Read**: ~10-50ms per operation (network latency)
|
||||
- **Write**: ~20-100ms per operation (network + disk)
|
||||
- **Limit**: Disk space limited only
|
||||
|
||||
## Security
|
||||
|
||||
### IndexedDB
|
||||
- Data stored in browser, not encrypted
|
||||
- Subject to browser security policies
|
||||
- Cleared when browser data is cleared
|
||||
|
||||
### Flask Backend
|
||||
- SQLite database file should be protected
|
||||
- Use HTTPS in production
|
||||
- Implement authentication if needed (not included by default)
|
||||
- Consider encrypting sensitive data before storage
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
Planned improvements:
|
||||
- PostgreSQL/MySQL backend support
|
||||
- Real-time sync between clients
|
||||
- Encryption at rest
|
||||
- Automatic backup scheduling
|
||||
- Multi-tenancy support
