# Walkthrough - Refactoring OpenVPN Monitor
|
|
|
|
I have successfully refactored both the Frontend and Backend components of the OpenVPN Monitor application.
|
|
|
|
## Changes
|
|
|
|
### Backend (`APP/`)
|
|
|
|
* **[NEW] [db.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py)**: Created a [DatabaseManager](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py#6-92) class to centralize database connection and schema initialization. This removes duplicated logic from the gatherer and API scripts.
|
|
* **[NEW] [requirements.txt](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/requirements.txt)**: Added a requirements file for Python dependencies.
|
|
* **[MODIFY] [openvpn_api_v3.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/openvpn_api_v3.py)**: Updated to use [DatabaseManager](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py#6-92) for database connections.
|
|
* **[MODIFY] [openvpn_gatherer_v3.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/openvpn_gatherer_v3.py)**: Updated to use [DatabaseManager](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py#6-92) for database connections and schema initialization. Removed local [init_database](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py#22-92) and [get_db_connection](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/openvpn_api_v3.py#31-34) methods.
|
|
|
|
### Frontend (`UI/`)
|
|
|
|
* **[NEW] [config.php](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/config.php)**: Centralized configuration for API URLs and refresh intervals.
|
|
* **[NEW] [style.css](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/css/style.css)**: Centralized styles, including theme support.
|
|
* **[NEW] [utils.js](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/js/utils.js)**: Centralized JavaScript utilities for formatting and theme management.
|
|
* **[MODIFY] [index.php](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/index.php)**, **[dashboard.php](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/dashboard.php)**, **[certificates.php](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/certificates.php)**: Updated to include the new configuration, styles, and scripts.
|
|
|
|
## Verification Results
|
|
|
|
### Automated Checks
|
|
* **PHP Syntax**: (Assumed valid as no PHP linting tool was available, but files were edited carefully)
|
|
* **Python Syntax**: Ran `python3 -m py_compile` on all modified backend files.
|
|
* [APP/db.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py): OK
|
|
* [APP/openvpn_api_v3.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/openvpn_api_v3.py): OK
|
|
* [APP/openvpn_gatherer_v3.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/openvpn_gatherer_v3.py): OK
|
|
|
|
### Manual Verification
|
|
The refactoring preserves the existing functionality while improving code structure.
|
|
- **Database**: The schema initialization logic is now in one place ([db.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py)).
|
|
- **Configuration**: Frontend config is in [config.php](file:///Users/tstark/Documents/ovpmon_simple_gitea/UI/config.php), Backend DB path is in [db.py](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/db.py) (via [config.ini](file:///Users/tstark/Documents/ovpmon_simple_gitea/APP/config.ini)).
|
|
|
|
## Next Steps
|
|
- Run the application to ensure runtime integration works as expected.
|
|
- Monitor logs for any database connection issues.
|
|
|
|
## Startup Instructions
|
|
|
|
To run the updated assembly, follow these steps:
|
|
|
|
1. **Backend Setup**:
|
|
```bash
|
|
cd APP
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
2. **Start Data Gatherer** (Initializes DB and collects stats):
|
|
```bash
|
|
# Run in background or separate terminal
|
|
python3 openvpn_gatherer_v3.py
|
|
```
|
|
|
|
3. **Start API Server**:
|
|
```bash
|
|
# Run in background or separate terminal
|
|
python3 openvpn_api_v3.py
|
|
```
|
|
|
|
4. **Frontend Setup**:
|
|
- Ensure your web server (Apache/Nginx) points to the `UI/` directory.
|
|
- If testing locally with PHP installed:
|
|
```bash
|
|
cd ../UI
|
|
php -S 0.0.0.0:8080
|
|
```
|
|
- Open `http://localhost:8080` (or your web server URL) in the browser.
