Using the Composer installation tool (Drupal Release 9 onwards)
From Drupal Release 9, the Composer installation tool is the preferred method for installing modules (plugins). Composer replaces the previous installation methods: directly, via a module's URL, or by manually downloading a package that contains the package and then unpacking it and installing it (see Note below).
Composer simplifies module installation by automatically fetching and installing the required versions of libraries and their dependencies. This ensures that all components, including transitive dependencies, are compatible and functional. It also generates a composer.lock file to maintain consistency across environments, ensuring the same versions of dependencies are installed everywhere. By automating dependency resolution, version control, and autoloading, Composer ensures that all necessary components are installed and integrated in a Drupal site seamlessly.
Note
The Composer installation tool cannot be used if your Drupal system is pre-Release 9. Use one of these installation methods instead:
Ensure that Composer has been installed on your Drupal system server. For details, see the official Composer website.
In a new tab on your computer, on the Drupal website, go to the XTM Connect – Drupal module page.
Scroll to the bottom of the page, to the Releases section. You see the details for the current (most recent) module (plugin) release.
To download the current version of the XTM Connect – Drupal module, mark the text in the Install: text box, and copy it to the Clipboard.
Fictitious example: composer require 'drupal/tmgmt_xtm:^7.1'.
Alternatively, if the listed XTM Connect – Drupal release is not suitable, select the View all releases link at the bottom of the page. You will see a list of previous releases. Follow steps 5. and 6. below.
To install an older version of XTM Connect – Drupal, select the name of the release that you require. A page containing installation files (packages) for that release is displayed.
In the Install section, at the top of the release page, mark the text in the Install: text box, and copy it to the Clipboard.
Fictitious example: composer require 'drupal/tmgmt_xtm_connect:^1.1'.
In either case (you want to download the current version of XTM Connect – Drupal or an older one), the Composer installation string for that release is now stored in the Clipboard.
On your computer, open the command-line interface.
At the prompt, enter the path for the location at which you want to install the module (plugin), on the server on which your Drupal instance is installed. (For example, in a Windows Command Prompt window, use the cd command to change to a different path.)
At the command prompt, when it is displayed, paste in the Clipboard contents (Composer installation string for the release you have selected). Then, press the appropriate key(s) to confirm your entry. (For example, in a Windows Command Prompt window, press Enter.)
The package that contains the release installation files is unpacked and the files are extracted. When all the module files have been installed, a confirmation message is displayed on screen. You can now leave the command-line interface.
To leave the command-line interface, enter the appropriate command for your operating system (example: Windows uses exit). Then, press the appropriate key(s) to confirm that you want to leave the command-line interface. (For example, in a Windows Command Prompt window, press Enter.)
Result: using Composer, you have installed the XTM Connect – Drupal plugin in your organization's Drupal instance.
To complete the necessary installation tasks, ensure that you have also installed the TMGMT plugin on the Drupal server and installed the required Translation Management modules in Drupal. (TMGMT on Drupal does not require any extra dependencies but, to enable it to be used, those additional modules must also be installed and activated.)
