How to transfer a website from port 3000 to port 80?

[AeShevch]

Greetings!
Please tell me how to make the frontend work on a standard port?
I tried to run through npm start -p 80, but I get a cyclic redirect

@AeShevch I found some documentation on this: https://nextjs.org/docs/api-reference/cli#production

@AeShevch Instead of running npm start -p 80, edit the start command in frontend/package.json. Change it from next start to next start -p 80. Then try running npm start. This should work as long as you don't have anything running on port 80.
