To expose a variable directly to the client browser, you must prefix the variable with NEXT_PUBLIC_ .
Vite requires a specific prefix to expose variables to your client-side code.
# .env.local (Developer A) DATABASE_URL="postgresql://localhost:5432/dev_a"
These values are automatically loaded into process.env , allowing you to access them anywhere in your server-side code:
To maintain a secure and clean codebase, follow this standard operational workflow when handling environment files. Step 1: Add .env.local to .gitignore immediately
By following this guide, you can leverage .env.local to create a more secure and flexible development workflow. If you'd like, I can: Show you Provide a .env.example template
You might be using a local Docker database, while your teammate prefers a cloud-based dev database. By using .env.local , you can both have different DATABASE_URL values without conflicting with each other’s code.
In a standard Node.js environment, environment variables are not automatically loaded. You need to use a popular utility package called dotenv . First, install the package: npm install dotenv Use code with caution.
There's no universal answer—it depends on your team's practices and risk tolerance. The industry consensus leans toward:
