⚙️ Configuration

Environment Variables

Cesium is configured to use an external tile provider.
Set the following environment variable in .env.local:

NEXT_PUBLIC_CESIUM_TOKEN=<your_cesium_token>
NEXT_PUBLIC_TILES_URL=<your_tile_provider_url>

You can get your own tokens here https://cesium.com/learn/ion/cesium-ion-access-tokens/

Cesium File Requirements

Cesium requires specific static assets to be served publicly.
This is handled with CopyWebpackPlugin in next.config.js.

Note: Each copy statement must include:

info: {
  minimized: true;
}

🛠️ Compatibility Notes

Integrating Cesium with Next.js can introduce build/runtime challenges.
This repository is configured to maximize compatibility between:

• CesiumJS
• Next.js 14+
• Vercel Deployment
