WeatherAPI.com Migration Summary

✅ Completed: Swap from Open-Meteo to WeatherAPI.com

What Changed

Before: Weather forecasts were generated by ChatGPT based on general knowledge After: Weather forecasts come from WeatherAPI.com (real-time, accurate data) and ChatGPT handles everything else

📋 Files Modified

1. src/hooks/useWeatherChat.js

  • ❌ Removed: fetchRealTimeWeather() - Used Open-Meteo API with geocoding
  • ❌ Removed: getWeatherCondition() - WMO weather code converter
  • ✅ Added: fetchWeatherFromWeatherAPI(city) - New WeatherAPI.com function
  • ✅ Updated: getWeatherForCity() - Now calls fetchWeatherFromWeatherAPI
  • ✅ Updated: sendChatMessageWithCity() - Now uses fetchWeatherFromWeatherAPI for weather context

2. Configuration Files

  • ✅ Created: .env.local.example - Template for environment variables
  • ✅ Created: WEATHERAPI_SETUP.md - Complete setup guide
  • ✅ Updated: README.md - Added WeatherAPI.com documentation
