Unrecognized PORT command

Question

In my localhost, running below command

PORT=4080 node server.js

But, it was throwing an unexpected error.

'PORT' is not recognized as an internal or external command, operable program or batch file.

Do I need to install any module or did I miss any syntax to run it properly?

Answer 1

Apart from cross-env, Below command can serve the purpose.

SET PORT=4080 && node server.js 

PS: Set environment variable for nodeJs, run command in project folder.

Answer 2

In Windows you can set scripts in package.json:

"start": " set PORT=portnumber && react-app-rewired start"

or

"start": " set PORT=3001 && react-script start".

It worked for me:

Answer 3

• Install this additional package cross-env in your node environment. The above command you mentioned is Unix (Ubuntu, Mac, etc…). In the windows environment, you need a different syntax and cross-env does your job.
• You can also create an .env file with

PORT=3006

and save it in your project directory.
