env-management

To separate environment variables, place public browser variables in a `.env.client` file using `NEXT_PUBLIC_*` prefixes, and store server secrets in a `.env.api` file to prevent secrets leakage. This split structure keeps configurations secure and maintainable.

The best way to manage environment variables for Cloudflare deployment is adopting a split file structure. By isolating server secrets in `.env.api` and public client variables in `.env.client`, you enforce safe handling and reduce misconfiguration during the build and deployment process.

To add new environment variables, insert client-side additions into `.env.client` and server-side additions into `.env.api`. Each file enforces clear usage and access rules, ensuring public browser access is restricted to only the appropriately prefixed variables.

You need to split dotenv files to enforce security rules and reduce misconfiguration across local development and deployment. Separating client-facing vars from server secrets ensures that sensitive data is never exposed to the browser, making configuration highly maintainable.

Yes, the split env file approach works seamlessly with Next.js applications. It enforces the `NEXT_PUBLIC_*` prefix convention for client-side variables in `.env.client`, while keeping your server-side logic isolated and secure within the `.env.api` file.
