1 # Composer template for Drupal projects
3 [![Build Status](https://travis-ci.org/drupal-composer/drupal-project.svg?branch=8.x)](https://travis-ci.org/drupal-composer/drupal-project)
5 This project template should provide a kickstart for managing your site
6 dependencies with [Composer](https://getcomposer.org/).
8 If you want to know how to use it as replacement for
9 [Drush Make](https://github.com/drush-ops/drush/blob/master/docs/make.md) visit
10 the [Documentation on drupal.org](https://www.drupal.org/node/2471553).
14 First you need to [install composer](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx).
16 > Note: The instructions below refer to the [global composer installation](https://getcomposer.org/doc/00-intro.md#globally).
17 You might need to replace `composer` with `php composer.phar` (or similar)
20 After that you can create the project:
23 composer create-project drupal-composer/drupal-project:8.x-dev some-dir --stability dev --no-interaction
26 With `composer require ...` you can download new dependencies to your
31 composer require drupal/devel:~1.0
34 The `composer create-project` command passes ownership of all files to the
35 project that is created. You should create a new git repository, and commit
36 all files not excluded by the .gitignore file.
38 ## What does the template do?
40 When installing the given `composer.json` some tasks are taken care of:
42 * Drupal will be installed in the `web`-directory.
43 * Autoloader is implemented to use the generated composer autoloader in `vendor/autoload.php`,
44 instead of the one provided by Drupal (`web/vendor/autoload.php`).
45 * Modules (packages of type `drupal-module`) will be placed in `web/modules/contrib/`
46 * Theme (packages of type `drupal-theme`) will be placed in `web/themes/contrib/`
47 * Profiles (packages of type `drupal-profile`) will be placed in `web/profiles/contrib/`
48 * Creates default writable versions of `settings.php` and `services.yml`.
49 * Creates `sites/default/files`-directory.
50 * Latest version of drush is installed locally for use at `vendor/bin/drush`.
51 * Latest version of DrupalConsole is installed locally for use at `vendor/bin/drupal`.
53 ## Updating Drupal Core
55 This project will attempt to keep all of your Drupal Core files up-to-date; the
56 project [drupal-composer/drupal-scaffold](https://github.com/drupal-composer/drupal-scaffold)
57 is used to ensure that your scaffold files are updated every time drupal/core is
58 updated. If you customize any of the "scaffolding" files (commonly .htaccess),
59 you may need to merge conflicts if any of your modfied files are updated in a
60 new release of Drupal core.
62 Follow the steps below to update your core files.
64 1. Run `composer update drupal/core --with-dependencies` to update Drupal Core and its dependencies.
65 1. Run `git diff` to determine if any of the scaffolding files have changed.
66 Review the files for any changes and restore any customizations to
67 `.htaccess` or `robots.txt`.
68 1. Commit everything all together in a single commit, so `web` will remain in
69 sync with the `core` when checking out branches or running `git bisect`.
70 1. In the event that there are non-trivial conflicts in step 2, you may wish
71 to perform these steps on a branch, and use `git merge` to combine the
72 updated core files with your customized files. This facilitates the use
73 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;
74 keeping all of your modifications at the beginning or end of the file is a
75 good strategy to keep merges easy.
77 ## Generate composer.json from existing project
79 With using [the "Composer Generate" drush extension](https://www.drupal.org/project/composer_generate)
80 you can now generate a basic `composer.json` file from an existing project. Note
81 that the generated `composer.json` might differ from this project's file.
86 ### Should I commit the contrib modules I download?
88 Composer recommends **no**. They provide [argumentation against but also
89 workrounds if a project decides to do it anyway](https://getcomposer.org/doc/faqs/should-i-commit-the-dependencies-in-my-vendor-directory.md).
91 ### Should I commit the scaffolding files?
93 The [drupal-scaffold](https://github.com/drupal-composer/drupal-scaffold) plugin can download the scaffold files (like
94 index.php, update.php, …) to the web/ directory of your project. If you have not customized those files you could choose
95 to not check them into your version control system (e.g. git). If that is the case for your project it might be
96 convenient to automatically run the drupal-scaffold plugin after every install or update of your project. You can
97 achieve that by registering `@drupal-scaffold` as post-install and post-update command in your composer.json:
101 "drupal-scaffold": "DrupalComposer\\DrupalScaffold\\Plugin::scaffold",
102 "post-install-cmd": [
112 ### How can I apply patches to downloaded modules?
114 If you need to apply patches (depending on the project being modified, a pull
115 request is often a better solution), you can do so with the
116 [composer-patches](https://github.com/cweagans/composer-patches) plugin.
118 To add a patch to drupal module foobar insert the patches section in the extra
119 section of composer.json:
124 "Patch description": "URL to patch"
129 ### How do I switch from packagist.drupal-composer.org to packages.drupal.org?
131 Follow the instructions in the [documentation on drupal.org](https://www.drupal.org/docs/develop/using-composer/using-packagesdrupalorg).
