You can also set the hostname to be different from the default of 0.0.0.0, this can be useful for making the application available for other devices on the network. The default hostname can be changed with -H, like so:
Terminal npx next dev -H 192.168.1.2
Production
next start starts the application in production mode. The application should be compiled with next build first.
The application will start at http://localhost:3000 by default. The default port can be changed with -p, like so:
Terminal npx next start -p 4000
Or using the PORT environment variable:
Terminal PORT=4000 npx next start
Good to know:
-PORT cannot be set in .env as booting up the HTTP server happens before any other code is initialized.
next start cannot be used with output: 'standalone' or output: 'export'.
