What are some common mistakes with environment variables?
Some common mistakes include hardcoding values, not using a .env file, and failing to validate inputs.
Can you explain why hardcoding values is a mistake?
Hardcoding values makes your application less flexible and harder to maintain, especially across different environments.
What is a .env file and how should I use it?
.env files store environment variables in a key-value format, allowing you to manage configurations easily without hardcoding.
How can I validate environment variable inputs?
You can validate inputs by checking for required variables, ensuring correct data types, and using libraries like dotenv.
