npm run build cannot access in localhost

Question

I want to test my react/ node.js web app with a production build. I already run npm run build at the app directory and created build folder.

I was unable to run the application using localhost:8080 (server port).

Are there any ways to double check if the application is actually running in that port or access production-ready application?

PS. I used serve to host the application but it posts error 404: The requested path could not be found

Thank you for your help.

(this option is not suitable for SSR frameworks like NUXT or NEXT) or if you don't have that option install an npm package that renders your compiled code by doing the following:

1. npm install -g serve
2. serve -s build and you have to see
