- Use environment variables for secrets.
Detailed Explanation
Using environment variables helps keep sensitive data, such as API keys and database URLs, secure. Instead of hardcoding these values in your code, which makes them vulnerable to being seen by anyone who can access your code, you store them in environment variables. This way, they are kept out of the codebase and can be safely accessed through the process.env object, reducing the risk of leaking sensitive information.
Examples & Analogies
Think of environment variables like a safe deposit box for valuables. Just as you wouldn't want your jewelry or important documents lying around in plain sight, you shouldn't leave sensitive information exposed in your code. By storing them in a secure location (the safe deposit box), you access them only when needed, ensuring they are well-protected.
