Installing and Managing Drupal Modules: Practical Guide
Last updated: March 2026 · Reading time: 7 minutes
Modules are the building blocks of Drupal. They extend core functionality with forms, SEO tools, media management, access controls, and much more. Installation is done in three steps — if you know the right workflow.
Step 1: Finding the Right Module
The module overview on drupal.org lists all available modules with statistics, documentation, and version compatibility. Three criteria are decisive when choosing:
Security coverage. The shield icon next to the version number indicates whether the module is monitored by the Drupal Security Team. Modules without security coverage are a risk.
Active maintenance. A module without updates for over a year is a warning sign. The number of open issues and the maintainers' response time provide insight.
Version compatibility. Only use releases highlighted in green. For yellow-highlighted releases, check the release notes to determine if the version is safe for your use case.
Steps 2 and 3: Integrating and Activating
Installation with Composer (recommended). Composer is the package manager for PHP and the Drupal-recommended approach. It resolves dependencies automatically and downloads all required libraries. A single command is sufficient: composer require drupal/modulename.
Manual installation. The module is downloaded from drupal.org, extracted, and moved to the modules/contrib directory. This approach requires manually resolving dependencies — error-prone with complex modules.
Activation via the backend. In the admin area under Extend, find the module, check the checkbox, and install.
Activation with Drush. Drush (Drupal Shell) is the terminal tool for Drupal administration. With drush en modulename, a module is activated — faster and without context switching between terminal and browser.

Do I have to use Composer?
Composer is the recommended approach and the standard for professional projects. Manual installation is possible but error-prone for modules with dependencies.
How many modules are available for Drupal 11?
Over 50,000 contrib modules exist in total, thousands of which are compatible with Drupal 11. The number is growing steadily as the community actively ports modules.
What is the difference between core and contrib modules?
Core modules are shipped with Drupal and maintained by the Drupal core team. Contrib modules come from the community and are maintained by their maintainers. Custom modules are developed individually for a project.
