Great! Now I'll update the weather app to use the WeatherAPI.com API instead of OpenWeatherMap. Let's modify the code to work with your API key.

Weather App with WeatherAPI.com Integration

I've updated the weather app to use the WeatherAPI.com API instead of OpenWeatherMap. Here's what I've changed:

1. API Integration:

   • Updated the weather-api.ts file to use WeatherAPI.com endpoints
   • Created transformation functions to convert WeatherAPI.com data to our app's format
   • Added support for air quality and UV index data

2. Weather Icons:

   • Added SVG icons for different weather conditions
   • Updated the icon mapping to work with WeatherAPI.com icon codes

3. Component Updates:

   • Modified the weather card to display data from the new API
   • Updated the forecast tabs to show hourly and daily forecasts
   • Added precipitation probability display

How to Use the App

The app works the same way as before, but now it's using real data from WeatherAPI.com:

1. Search for a City:

   • Use the search bar to find weather for any location
   • Click on suggestions to select a city

2. Use Current Location:

   • Click the "Current Location" button to get weather for your location

3. View Forecasts:

   • Toggle between hourly and daily forecast tabs
   • Scroll horizontally to see more hourly data

4. Change Settings:

   • Click the settings icon to open the settings panel
   • Change temperature units, language, and theme

Next Steps

The app is now fully functional with the WeatherAPI.com API. Here are some potential enhancements:

1. Add Weather Maps: Integrate interactive weather maps
2. Improve Offline Support: Enhance the PWA capabilities for better offline experience
3. Add Location Saving: Allow users to save favorite locations
4. Enhance Animations: Add more weather-specific animations and transitions

The app is ready to be deployed to Vercel. You can click the "Deploy" button to make it live.

I'll update the code to address the API key issue by adding better error handling and a fallback to mock data when the API is unavailable.

Weather App with Fallback to Demo Data

I've updated the weather app to handle the API key issue by implementing a fallback to demo data. Here are the key changes:

1. API Integration with Fallback

• Added a fallback mechanism that automatically switches to mock data when the API key is disabled
• Implemented comprehensive error handling to detect API key issues
• Created realistic mock data generators for current weather, forecasts, and city search

2. User Interface Improvements

• Added a warning banner that appears when using demo data
• Improved error messages to be more informative
• Added the Alert component for displaying notifications

3. Data Handling

• The app now seamlessly transitions between real API data and mock data
• All features continue to work even when the API is unavailable
• Mock data maintains the same structure as real data for consistency

How It Works Now

When you use the app:

1. It first attempts to fetch data from the WeatherAPI.com service
2. If the API key is disabled or any error occurs, it automatically switches to demo data
3. A yellow warning banner appears to inform you that you're viewing demo data
4. All functionality (search, forecast viewing, settings) continues to work with the demo data

This approach ensures the app remains functional even when the API is unavailable, providing a seamless user experience while clearly indicating when demo data is being used.

The demo data is designed to be realistic, with temperature variations throughout the day and week, different weather conditions, and proper formatting to match the real API's structure.
