Composer template for Drupal + DDEV

This project template provides a starter kit for managing your site dependencies with Composer. It is forked from the Drupal Composer project with some minor tweaks to work better with DDEV and installs several contrib modules I use on most projects.

Usage

install Git
Install Docker
Install DDEV
git clone git@github.com:rjtownsend/drupal-ddev.git
cd into installation directory, run ddev config, and configure as follows:
- Project name: must be lower case, no underscores, hyphens allowed. This will also be the URL where the site is located; eg. my-project will be located at https://my-project.ddev.site
- Project root: docroot (if ddev asks to create docroot, say yes)
- Project type: drupal10
Run ddev start and then ddev composer install
- Read here if you receive the warning message "mkcert may not be properly installed".

Useful DDEV commands

ddev auth ssh loads all your local ssh keys into DDEV
ddev npm install does what you would think
ddev npm exec gulp also does what you would think
ddev import-db < ./local_DATE.sql.gz and ddev export-db > ./local_DATE.sql.gz
ddev drush [command]
ddev composer [command

What does the template do?

When installing the given composer.json some tasks are taken care of:

Drupal will be installed in the docroot-directory.
Autoloader is implemented to use the generated composer autoloader in vendor/autoload.php, instead of the one provided by Drupal (docroot/vendor/autoload.php).
Modules (packages of type drupal-module) will be placed in docroot/modules/contrib/
Theme (packages of type drupal-theme) will be placed in docroot/themes/contrib/
Profiles (packages of type drupal-profile) will be placed in docroot/profiles/contrib/
Creates default writable versions of settings.php and services.yml.
Creates docroot/sites/default/files-directory.
Latest version of drush is installed locally for use at vendor/bin/drush.
Latest version of DrupalConsole is installed locally for use at vendor/bin/drupal.
Creates environment variables based on your .env file. See .env.example.

Updating Drupal Core

This project will attempt to keep all of your Drupal Core files up-to-date; the project drupal/core-composer-scaffold is used to ensure that your scaffold files are updated every time drupal/core is updated. If you customize any of the "scaffolding" files (commonly .htaccess), you may need to merge conflicts if any of your modified files are updated in a new release of Drupal core.

Follow the steps below to update your core files.

Run composer update "drupal/core-*" --with-dependencies to update Drupal Core and its dependencies.
Run git diff to determine if any of the scaffolding files have changed. Review the files for any changes and restore any customizations to .htaccess or robots.txt.
Commit everything all together in a single commit, so web will remain in sync with the core when checking out branches or running git bisect.
In the event that there are non-trivial conflicts in step 2, you may wish to perform these steps on a branch, and use git merge to combine the updated core files with your customized files. This facilitates the use of a three-way merge tool such as kdiff3. This setup is not necessary if your changes are simple; keeping all of your modifications at the beginning or end of the file is a good strategy to keep merges easy.

FAQ

Should I commit the contrib modules I download?

Composer recommends no. They provide argumentation against but also workrounds if a project decides to do it anyway.

Should I commit the scaffolding files?

The Drupal Composer Scaffold plugin can download the scaffold files (like index.php, update.php, …) to the web/ directory of your project. If you have not customized those files you could choose to not check them into your version control system (e.g. git). If that is the case for your project it might be convenient to automatically run the drupal-scaffold plugin after every install or update of your project. You can achieve that by registering @composer drupal:scaffold as post-install and post-update command in your composer.json:

"scripts": {
    "post-install-cmd": [
        "@composer drupal:scaffold",
        "..."
    ],
    "post-update-cmd": [
        "@composer drupal:scaffold",
        "..."
    ]
},

How can I apply patches to downloaded modules?

If you need to apply patches (depending on the project being modified, a pull request is often a better solution), you can do so with the composer-patches plugin.

To add a patch to drupal module foobar insert the patches section in the extra section of composer.json:

"extra": {
    "patches": {
        "drupal/foobar": {
            "Patch description": "URL or local path to patch"
        }
    }
}

How do I specify a PHP version?

This project supports PHP 8.1 as minimum version (see Environment requirements of Drupal 10), however it's possible that a composer update will upgrade some package that will then require PHP 8.1+.

To prevent this you can add this code to specify the PHP version you want to use in the config section of composer.json:

"config": {
    "sort-packages": true,
    "platform": {
        "php": "8.1.13"
    }
},
