What are the differences between cross-env and env-cmd?

Both cross-env and env-cmd are tools for setting environment variables, but they have different use cases. Cross-env is primarily used for cross-platform compatibility, allowing you to set environment variables in a way that works on both Windows and Unix systems. Env-cmd, on the other hand, is used to load environment variables from a file, making it easier to manage multiple configurations.

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

Sure! For cross-env, you might use it in a script like this: cross-env NODE_ENV=production node app.js. For env-cmd, you would typically have a .env file and run: env-cmd .env node app.js.

Which one should I use for a Node.js project?

It depends on your needs. If you need cross-platform support, go with cross-env. If you want to manage multiple environment configurations easily, env-cmd is a better choice.

Are there any performance differences between them?

Generally, the performance difference is negligible for most applications. The choice should be based more on functionality and ease of use rather than performance.
