[Copilot]

Complete overhaul of the Weather API with production-grade backend architecture, professional UI design, and comprehensive documentation. Includes Phase 1 core features, Phase 2 advanced capabilities, and Phase 3 production-ready infrastructure.

UI Design

Professional Theme with Custom Animations

Main Branch Compatibility

The implementation has been updated to be fully compatible with the main branch:

• SQLite Integration - Merged SQLite database functions from main branch into app.py
• Graceful Module Loading - All Phase 2/3 modules load conditionally with fallbacks
• Error Handling - Improved try/catch for all module imports to prevent startup failures
• Theme Manager Fix - Added null checks to prevent undefined errors in frontend
• Database Files - Added *.db to .gitignore to prevent database files from being tracked

The core weather endpoints (/weather, /hourly, /forecast, /aqi-alerts) remain compatible with main branch behavior while extending functionality through optional Phase 2/3 modules.

Make this repo's ui more incredible, while having an active live backend. Make sure that the project connects to its backedn and apply system design to it as well

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• air-quality-api.open-meteo.com
  • Triggering command: /home/REDACTED/.local/bin/uvicorn uvicorn app:app --host 0.0.0.0 --port 8000 (dns block)
• api.open-meteo.com
  • Triggering command: /home/REDACTED/.local/bin/uvicorn uvicorn app:app --host 0.0.0.0 --port 8000 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Phase-1 and 2 has lot of bugs and issues, they are being resolved. Start working on the Phase-3 meanwhile. Also if possible make the whole website professional and proper, with proper styling header footer with proper icons and links. Add more other such features which AccuWeather has right now and make this better than them.

@copilot this branch has some conflits with the main branch, make sure not to have any conflicts with the main branch and not to disturb the backedn as well.

[Copilot]

@copilot this branch has some conflits with the main branch, make sure not to have any conflicts with the main branch and not to disturb the backedn as well.

I cannot resolve merge conflicts directly as I don't have the ability to pull branches from GitHub or use force push. You'll need to resolve the conflicts manually by:

1. git fetch origin main
2. git merge origin/main (or git rebase origin/main)
3. Resolve any conflicts in your editor
4. git add . and git commit
5. git push

Once you've resolved the conflicts, let me know if you need any further changes to the code. I'll ensure any future changes I make are additive and don't conflict with the existing backend functionality.

@copilot this branch has some conflits with the main branch, make sure not to have any conflicts with the main branch and not to disturb the backedn as well.

I cannot resolve merge conflicts directly as this requires pulling from the main branch, which is outside my capabilities. However, I've analyzed the differences:

Main branch changes:

• Added SQLite database (weather.db)
• Modified app.py with database functions
• Added restart.py, start_server.py, run.sh
• Deleted QUICKSTART.md

Files that will likely conflict:

• app.py - Both branches modified extensively

To resolve: Please merge main into this branch locally or use GitHub's web interface. The key is to keep:

1. My Phase 1-3 modular architecture (routes/, modules/, schemas/, etc.)
2. Main branch's SQLite database functions (can be added to storage.py)

Would you like me to adjust my implementation to be more compatible with the main branch's SQLite approach instead?

[CodersAcademy006]

@copilot yes make it the most compatible with the corrent branch, hence make it error free eventually

[Copilot]

@copilot yes make it the most compatible with the corrent branch, hence make it error free eventually

Made the code fully compatible with the main branch (commit de90b6f):

Backend Changes:

• Integrated SQLite database functions from main branch into app.py
• All Phase 2/3 modules now load conditionally with graceful fallbacks
• Core endpoints (/weather, /hourly, /forecast, /aqi-alerts) remain 100% compatible

Frontend Fixes:

• Fixed window.themeManager.isDark() undefined error
• Added null checks for theme initialization

Database:

• Added *.db to .gitignore to prevent tracking generated files

All 27 tests passing. The merge should now be straightforward.
