Composer

Note: If you need to install only one Drupal site, please refer to "How to install Drupal 10 directly on the web server and on a shared web hosting plan using Composer, without needing localhost".

Note: If you need to install multiple sites using multiple installations of Drupal 10 on a shared web hosting plan, please refer to "How to build multiple Drupal 10 sites directly on the web server using Composer, on a shared web hosting plan, without using git or localhost".

Many secure Content Management Systems like Drupal have switched over to Composer to install the CMS as well as to manage the website installed using such CMS.
