What should I do if a required variable is missing?

You can throw an error or log a message indicating which variable is missing. It's also good to provide a fallback.

Can I validate the variables after loading them?

Yes, you can create a validation function to check if all required variables are present and valid after loading.

Is there a way to load different .env files for different environments?

Absolutely! You can specify different .env files based on the environment by using a conditional statement in your code.
