Initial Setup (Source code)

1. Install Bun (fast all-in-one JavaScript runtime & package manager).
2. Acquire weather.com, mapbox.com, developer.tomtom, and HERE.com API keys. These are required for weather data, radar frames, and traffic, respectively.
3. Go to /main/configs and open yourConfig.json.
4. Line 4 is where your weather.com API key goes. Replace "YOUR_API_KEY" with your weather.com API key.
5. Line 5 is where your mapbox.com API key goes. Replace "YOUR_API_KEY" with your mapbox.com API key.
6. Line 6 is where your developer.tomtom.com API key goes. Replace "YOUR_API_KEY" with your developer.tomtom.com API key. (optional, only if you want traffic report)
7. Line 7 is where your HERE.com API key goes. Replace "YOUR_API_KEY" with your HERE.com API key. (optional, only if you want traffic flow)
8. Save your changes to yourConfig.json and close it.
9. In your terminal within the project directory, run bun install. (This project has no external dependencies thanks to Bun, but this step creates the lockfile and prepares scripts.)
10. Run the simulator with:

    bun run start

    Or simply:

    bun app.js

    For development with auto-reload on file changes:

    bun run dev

Note: This project has been adapted to run natively on Bun using its built-in high-performance HTTP server. No more node_modules bloat or slow startup!

Enjoy the nostalgia! You're all set.
