.env.development.local ~repack~

To avoid this pitfall, follow these best practices with Vite:

export default async function HomePage() const users = await getUsers(); // Safe: runs only on the server // Pass only the necessary data to client components return <UserList initialUsers=users />;

When you run NODE_ENV=development node app.js , dotenv-flow will load variables in the priority order: .env.development.local → .env.local → .env.development → .env . .env.development.local

CRA has native support for this pattern. When you run npm start , it automatically loads:

VITE_API_BASE_URL=http://localhost:3000 VITE_APP_TITLE="My App (Dev Local)" To avoid this pitfall, follow these best practices

In modern web development, managing configuration settings across different environments—like development, staging, and production—is a fundamental requirement. Among the various files used for this purpose, .env.development.local holds a specific and powerful role. Among the various files used for this purpose,

# .env.development.local (local only) DEBUG_LEVEL=trace USE_MOCK_PAYMENT_GATEWAY=false

In essence, .env.development.local is a file for .

: .env.local is loaded in all environments (except test), while .env.development.local is loaded only when NODE_ENV=development . If your server is not explicitly in development mode (or if NODE_ENV is misconfigured), .env.development.local may be ignored. Use .env.local for truly universal local overrides, and .env.development.local for overrides that should apply only during development.
