If you'd like to share (e

Using a development-specific key allows engineering teams to call staging mocks or sandbox APIs. This eliminates the risk of accidentally running up massive financial bills or consuming production API limits during rigorous testing.

Different developers might have different local setups (e.g., different database port numbers). The .env.development file allows each developer to customize their local environment without affecting others [Believemy, 2024]. 3. Environment Switching

: Many frameworks, such as React (Create React App) or Vite, automatically detect and load this file when you run a command like npm start or npm run dev . Common Example A typical .env.development file might look like this: Stop the server ( Ctrl+C ) and restart it
