serve -s build specify port number

Question

I'm trying to serve a react-app's build folder from a DigitalOcean droplet.

After I run yarn build, I get told by the script to run

yarn global add serve serve -s build

However, when I run serve -s build, It say's it's running on http://localhost:5000. I would like it run on localhost:3000 instead, as I have another server running on port 5000. How can i specify the port number such that serve -s build runs on port 3000?

You can use the -l option (lowercase L). serve -l 3000 -s build – Fp

Answer 1

From typing serve --help, I found

-l, --listen listen_uri            
Specify a URI endpoint on which to listen

For TCP ports on hostname "localhost":

$ serve -l 1234

In your case, you can just use

serve -l 3000 -s build

to specify that you want to serve the app on port 3000

Answer 2

To Run your build code on a different port, use the command given below

---

serve -l 3000 -s build

---

Here, -l denotes the port number on which port you want to run your code, and -s denotes which file you want to serve.
