.env.development 💯

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:

: Avoid manually changing variables every time you move from writing code locally to deploying it.

: Keep local development settings separate from production secrets.

: Using a local development database rather than the live production database.
