How do different environment variable tools compare?

What are the main differences between dotenv and config for managing environment variables?

Dotenv is a simple way to load environment variables from a .env file, while config allows for more complex configurations and supports multiple environments.

Which one is better for a Node.js application?

It depends on your needs. If you just need to load variables from a file, dotenv is easier. For more complex setups, config might be better.

Can you give me an example of when to use each?

Use dotenv for small projects or prototypes where you need quick setup. Use config for larger applications with different environments like development, testing, and production.

Are there any other tools I should consider?

Yes, you might also look into tools like env-cmd or cross-env, which offer additional features for managing environment variables.
