The composer update command should be run after any git pull or git fetch. Other installations will pick this change up the next time they do git pull, and they will get the new module when they run composer update. Then the change to composer.json needs to be committed and pushed to the repository. To update the files any time they might have changed, navigate to the Drupal root on the command line and run: composer updateĪdd additional Drupal contributed modules, libraries, and themes at any time from the project root with the same command used earlier: composer require drupal/module_name will add another line to the composer.json file for the new module. # Ignore directories generated by Composer gitignore, code in /web/modules/custom and the content of the /web/sites subdirectory (other than the files directory) will be stored in the git repository.gitignore gitignore file that keeps them out (this was added as a part of the composer packaging). The files downloaded by Composer do not need to be added to the repo. Commit Files to the RepoĬommit the composer.json changes to the repo. See more details about all these options at. The composer.json file will then become the equivalent of a Drush make file, with documentation of all your modules.įor even more parity with Drush Make, you can add external libraries to your composer.json as well, and, with a plugin, you can also add patches to it. Repeat until all desired contributed modules have been added. You can peek into the composer.json file at the root of the project and see the ‘require’ list evolving. Instead of adding modules using drush dl, add additional modules by running composer commands from the project root (one level above the Drupal root): composer require drupal/migrate_upgrade require drupal/migrate_plus you go, each module will be downloaded from Packagist and composer.json will be updated to add this module to the module list. Navigate to EXAMPLE.COM/install to provide the database credentials and follow the instructions.Īdding contributed modules is done a little differently.Copy to settings.php and unprotect it.The manual process for installing Drupal 8 is: vendor/bin/drush site-install you don’t do the installation with Drush you can do it manually, but the Drush installation handles all this for you. If you have an empty database you can then install Drupal using the Drush version in the package: cd drupal/web The right version of Drush for Drupal 8 comes built into this package. There is an ongoing discussion about how to fix that. That’s because the current Drupal versioning system doesn’t qualify as the semantic versioning the system needs. The contributed modules are coming from Packagist rather than directly from. A README.md file there describes the process for doing things like updating core. You can also see rules that move contributed modules into ‘/contrib’ subfolders as they’re downloaded. You can see the beginning of the module list in the ‘require’ section, and that Drush and Drupal Console are included by default. You will end up with a composer.json file at the base of the project that might look like the following. The new file structure will look like this: It also moves the vendor directory outside of the web root. The packaging process downloads all the core modules, Devel, Drush and Drush Console, and then moves all the Drupal code into a ‘web’ subdirectory. Sudo composer create-project drupal-composer/drupal-project:~8.0 drupal -stability dev -no-interaction To create a new Drupal project using Composer, type the following on the command line, where /var/drupal is the desired code location: cd /var See for more information about installing Composer. Let's talk through the whole process, step by step. The first step is to install Composer on your local system. vendor/bin/drush site-install Install Composer TLDR: How to go from an empty directory to a fully functional Drupal site in two command lines: sudo composer create-project drupal-composer/drupal-project:~8.0 drupal -stability dev -no-interaction Anyone who’s used to Drush would probably find it pretty easy to get this up and running. I was a little worried about changing the process I’ve used for a long time, but my worries were for nothing. The process is actually very handy, sort of the way we’ve used Drush Make in the past, where you don’t actually store all the core and contributed module code in your repository, you just record which modules and versions you’re using and pull them in dynamically. After installing D8 manually from scratch so many times, I decided to sit down and figure out how to build a Drupal site using Composer to make it easier. I’ve built and rebuilt many demo Drupal 8 sites while trying out new D8 modules and themes and experimenting with new functionality like migrations.
