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

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

Both env-cmd and cross-env are tools for managing environment variables in Node.js applications, but they serve slightly different purposes. env-cmd allows you to load environment variables from a file, while cross-env is used to set environment variables across different operating systems.

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

Sure! For env-cmd, you would use it like this: env-cmd .env node app.js. For cross-env, you would write: cross-env NODE_ENV=production node app.js.

Which one should I use for a new project?

It depends on your needs. If you want to load variables from a file, go with env-cmd. If you need cross-platform compatibility for setting variables, choose cross-env.

Are there any performance differences between them?

Generally, the performance difference is negligible for most applications. However, env-cmd might have a slight overhead when loading from a file.
