Node.js进程的view.env变量

Question

I use package dotenv to set env variables in .env file. Here is the content of .env :

NODE_ENV=development
PORT=4000

Then, I run nodemon --exec babel-node -- src/index.js to start the project. How to check value of env variables by command line?

I don't want to use console.log in the JS source code, I want something like so (in terminal):

node
> process.env

But it doesn't show the values I have set in .env file.

Could you give me some resolution?

Answer 1

From your console, type following for mac/ubuntu:

echo $NODE_ENV

and following for windows:

 echo %NODE_ENV% 

Answer 2

If you want to avoid the use of dotenv as sometimes it creates confusion that where to call the dotenv. So, you can use foreman node module and can start your project by command nf start. It will automatically load.env variables into your project without calling dotenv.
