To add environment variables to a .NET and SvelteKit project, you configure backend variables in appsettings.json and map them to Options classes, while updating .env files and Dockerfile build arguments for the frontend. This ensures proper configuration across both environments.

Exposing public frontend variables in SvelteKit involves updating your .env files and passing them as build-time arguments in the Dockerfile. This approach securely handles public frontend variables while keeping private secrets isolated on the backend.

Securely handling API keys in a SvelteKit application requires adding the key to the backend configuration, such as appsettings.json, and only exposing it to the frontend through controlled build-time arguments if strictly necessary. This maintains secure handling of secrets and runtime configuration.

Yes, Aspire integration supports backend environment variable configuration in .NET. It facilitates adding and managing variables by integrating with appsettings.json and mapping them directly to Options classes for consistent runtime configuration.

Updating your Dockerfile is necessary when adding environment variables to a frontend application because public frontend variables are often injected during the build process. This ensures the variables are correctly compiled and available at runtime without exposing private secrets.
