I am using NestJS and I am new to it.

I have read that NODE_ENV is an environment variable that specifies the environment, introduced by Express.

Since NestJS is based on Express, I don't know if NODE_ENV is also relevant for NestJS.

Is it still recommended to set NODE_ENV when using NestJS? Or is it not necessary for NestJS?

Setting environment variables is up to your needs, and for NODE_ENV if your application doesn't' support any kind of several environment like prod, dev.. than you're not necessary to add it.

In case you are going to use environment variables, make sure to read this:

It will save you a lot of trouble!
