Flight Radar Application

I'll create a flight tracking application similar to FlightRadar24 with a map on the left and search/information panels on the right. The app will query different REST endpoints to fetch flight data.

I'll fix the error by properly handling the Leaflet map integration in Next.js. The main issue is that Leaflet requires a browser environment and doesn't work well with server-side rendering.

I've fixed the error by making several important changes:

1. Separated the map into its own component: I created a dedicated flight-map.tsx component that's dynamically imported with ssr: false to ensure Leaflet only loads on the client side.
2. Fixed Leaflet marker icons: I'm now using absolute URLs from unpkg for the marker icons to ensure they load properly.
3. Created a custom plane icon: Instead of trying to load an image file, I'm using a div icon with an SVG for the plane markers.
4. Added mock data generation: I've included helper functions to generate mock flight and airport data for demonstration purposes.
5. Simplified the map implementation: The new implementation avoids complex Leaflet configurations that might cause errors.
6. Added a map view controller: This component ensures the map view updates properly when the center or zoom changes.

The application now has:

• A map on the left showing flights and airports
• A sidebar on the right with tabs for flights, search results, and detailed information
• Mock data generation to simulate real flight tracking
• Proper handling of client-side only libraries like Leaflet

This implementation should work correctly in the Next.js environment without the previous rendering errors.
