: Enabling "debug mode" or experimental features only while building.
In many frameworks like React , Vite, and Next.js, the build tools automatically look for a .env.development file when you run a local development command (such as npm run dev ). This allows you to: .env.development
: Keep local development settings separate from production secrets. : Enabling "debug mode" or experimental features only
: Pointing to a local server (e.g., http://localhost:3000 ) instead of a production domain. .env.development
