In your package.json you need to make sure

Change

"start": "react-scripts start"

to

Linux:

"start": "PORT=3006 react-scripts start"

or

"start": "export PORT=3006 react-scripts start"

Windows:

"start": "set PORT=3006 && react-scripts start"

Also the best way in my opinion and the one I use is to create a file called

.env.development

at the same level of your package.json

and add

PORT=3006

to your file.

Notice that you can create different .env files like .env.production etc... or simply .env
