Installing Drupal Modules with Composer

The command

composer require drupal/module_name

is used in Drupal to install a new module or package into your Drupal project using Composer.

Here, `drupal/module_name` should be replaced with the actual name of the module you want to install. For example, if you want to install the "Views" module, the command would be:

composer require drupal/views

This command will download the module and all of its dependencies, and then update your `composer.json` file and `composer.lock` file to reflect the changes. Finally, it will install the module into the appropriate directory within your Drupal project.
