Laravel + React project not working without php artisan serve command

I am working on Laravel React project on localhost when I run a command

PHP artisan serve

It is working fine on http://127.0.0.1:8000/ But when I am trying to run it without php artisan serve command and trying to access with

http://localhost/project_name

It is not working. I follow all necessary changes like

1. Move .htaccess to root folder
2. server.php to index.php

Not any error just blank page
