# Composer template for Drupal projects [![Build Status](https://travis-ci.org/drupal-composer/drupal-project.svg?branch=8.x)](https://travis-ci.org/drupal-composer/drupal-project) This project template should provide a kickstart for managing your site dependencies with [Composer](https://getcomposer.org/). If you want to know how to use it as replacement for [Drush Make](https://github.com/drush-ops/drush/blob/master/docs/make.md) visit the [Documentation on drupal.org](https://www.drupal.org/node/2471553). ## Usage First you need to [install composer](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx). > Note: The instructions below refer to the [global composer installation](https://getcomposer.org/doc/00-intro.md#globally). You might need to replace `composer` with `php composer.phar` (or similar) for your setup. After that you can create the project: ``` composer create-project drupal-composer/drupal-project:8.x-dev some-dir --stability dev --no-interaction ``` With `composer require ...` you can download new dependencies to your installation. ``` cd some-dir composer require drupal/devel:~1.0 ``` The `composer create-project` command passes ownership of all files to the project that is created. You should create a new git repository, and commit all files not excluded by the .gitignore file. ## What does the template do? When installing the given `composer.json` some tasks are taken care of: * Drupal will be installed in the `web`-directory. * Autoloader is implemented to use the generated composer autoloader in `vendor/autoload.php`, instead of the one provided by Drupal (`web/vendor/autoload.php`). * Modules (packages of type `drupal-module`) will be placed in `web/modules/contrib/` * Theme (packages of type `drupal-theme`) will be placed in `web/themes/contrib/` * Profiles (packages of type `drupal-profile`) will be placed in `web/profiles/contrib/` * Creates default writable versions of `settings.php` and `services.yml`. * Creates `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`. ## Updating Drupal Core This project will attempt to keep all of your Drupal Core files up-to-date; the project [drupal-composer/drupal-scaffold](https://github.com/drupal-composer/drupal-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 modfied files are updated in a new release of Drupal core. Follow the steps below to update your core files. 1. Run `composer update drupal/core --with-dependencies` to update Drupal Core and its dependencies. 1. 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`. 1. 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`. 1. 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](http://www.gitshah.com/2010/12/how-to-setup-kdiff-as-diff-tool-for-git.html). 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. ## Generate composer.json from existing project With using [the "Composer Generate" drush extension](https://www.drupal.org/project/composer_generate) you can now generate a basic `composer.json` file from an existing project. Note that the generated `composer.json` might differ from this project's file. ## 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](https://getcomposer.org/doc/faqs/should-i-commit-the-dependencies-in-my-vendor-directory.md). ### Should I commit the scaffolding files? The [drupal-scaffold](https://github.com/drupal-composer/drupal-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 `@drupal-scaffold` as post-install and post-update command in your composer.json: ```json "scripts": { "drupal-scaffold": "DrupalComposer\\DrupalScaffold\\Plugin::scaffold", "post-install-cmd": [ "@drupal-scaffold", "..." ], "post-update-cmd": [ "@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](https://github.com/cweagans/composer-patches) plugin. To add a patch to drupal module foobar insert the patches section in the extra section of composer.json: ```json "extra": { "patches": { "drupal/foobar": { "Patch description": "URL to patch" } } } ``` ### How do I switch from packagist.drupal-composer.org to packages.drupal.org? Follow the instructions in the [documentation on drupal.org](https://www.drupal.org/docs/develop/using-composer/using-packagesdrupalorg).
