What are some alternatives to dotenv for Node.js?

There are several alternatives to dotenv for managing environment variables in Node.js, such as config, env-cmd, and cross-env. Would you like to know more about any specific one?

Can you explain how config works?

Sure! The config package allows you to manage configuration settings in a structured way. You can create different configuration files for different environments (like development, testing, and production) and load them based on the NODE_ENV variable.

What about env-cmd? How does it differ from dotenv?

env-cmd is a command-line tool that allows you to load environment variables from a file before running your Node.js application. Unlike dotenv, which loads variables at runtime, env-cmd can be used to set variables for the entire command execution.

Are there any performance differences between these options?

Generally, the performance differences are minimal for most applications. However, if you're loading a large number of environment variables, using env-cmd might be slightly faster since it loads them all at once before execution.
