Commit Message: feat: Implement web calendar application with Flask, Docker, and calendar integration Description: 1. Server Refactor: • Moved application logic from main.py to a structured directory server/app/. • Added server/app/__init__.py for Flask app initialization. • Introduced server/app/views.py to handle routes (dashboard and dashboard_image). • Created server/app/models.py for event modeling, supporting CalDAV and iCalendar events. • Added server/app/weather.py to fetch weather data using OpenWeatherMap API. 2. New Features: • Added an image generation route (/image) to render calendar views as BMP images. • Integrated OpenWeatherMap API for weather data on the dashboard. 3. Environment and Configurations: • Added a Dockerfile to build and deploy the app using uwsgi-nginx-flask. • Introduced compose.yml for running the app with Docker Compose. • Moved uwsgi.ini configuration to server/uwsgi.ini for modular organization. 4. Dependencies: • Updated requirements.txt to include new dependencies: imgkit, pillow, and Werkzeug==2.2.2. 5. Static Assets: • Added placeholder images out.png and test.png. 6. Code Cleanup: • Removed old files (main.py and root-level uwsgi.ini). • Updated .gitignore to include .idea/ folder. Additional Notes: • Enhanced event parsing to handle all-day and time-specific events using server/app/models.py. • Utilized Flask’s render_template for dynamic HTML rendering and imgkit for HTML-to-image conversion. • Integrated multiple calendar sources (CalDAV and public iCal feeds). Let me know if you need further adjustments!
