Acquia Site Studio

Build Status

Installation with composer

Using composer is the preferred way of managing your modules and themes as composer handles dependencies automatically and there is less margin for error. You can find out more about composer and how to install it here: It is not recommended to edit your composer.json file manually.

Open up your terminal and navigate to your project root directory.

Run the following commands to require the module and minimal theme:

composer require acquia/cohesion
composer require acquia/cohesion-theme

Site Studio will install along with several module dependencies from

You can now enable the modules via drush with the following commands:

drush cr
drush pm-enable cohesion cohesion_base_styles cohesion_custom_styles cohesion_elements cohesion_style_helpers cohesion_sync cohesion_templates cohesion_website_settings sitestudio_page_builder -y

Upgrading Site Studio

When upgrading to a newer version of Site Studio, the following series of commands will need to be run in this order:

drush cr 
drush updb -y 
drush cohesion:import / drush cohesion-import
drush cohesion:rebuild / drush cohesion-rebuild

Drush integration (supports ^9)

The cohesion drush command has the following operations:


Re-save and run pending updates on all Site Studio config entities.

Drush 9 format:

drush cohesion:rebuild

Drush 8 format:

drush cohesion-rebuild


Import assets and rebuild element styles (replacement for the CRON).

Drush 9 format:

drush cohesion:import

Drush 8 format:

drush cohesion-import


Several hooks are provided and documented in ./cohesion.api.php.

All hooks are in the dx8 group, so can be implemented in a file under your module's root if you wish.

Global $settings options

Show the JSON fields for debugging:

$settings['dx8_json_fields'] = TRUE;    

Allow the API URL field on the account settings page to be editable:

$settings['dx8_editable_api_url'] = TRUE;

Expose a version number field on the account settings page (for development):

$settings['dx8_editable_version_number'] = TRUE;

Don't show the API key field on the account settings page:

$settings['dx8_no_api_keys'] = TRUE;

Don't show the Google API key page:

$settings['dx8_no_google_keys'] = TRUE;

Set the temporary stream wrapper that cohesion should use:

$settings['coh_temporary_stream_wrapper'] = 'mytemp://';

$settings['site_studio_sync'] = '../config/sync';

Set the max number of entities to import via sync in the batch process:

$settings['sync_max_entity'] = 10;

Set the max number of entities to rebuild at one time in the rebuild batch process:

$settings['rebuild_max_entity'] = 10;

Site Studio Events

When certain Site Studio operations are taking place events are dispatched so that you can interact with it, but you must write your own event subscribers to subscribe to the relevant events. The main Site Studio module's events can be found within the \Drupal\cohesion\SiteStudioEvents class.

Pre Site Studio Rebuild

When a Site Studio rebuild operation is started the PreRebuildEvent will be dispatched.

To subscribe: Drupal\cohesion\SiteStudioEvents::PRE_REBUILD

The dispatched event is Drupal\cohesion\Event\PreRebuildEvent.

Post Site Studio Rebuild

When a Site Studio rebuild operation is complete the PostRebuildEvent will be dispatched.

To subscribe: Drupal\cohesion\SiteStudioEvents::POST_REBUILD

The dispatched event is Drupal\cohesion\Event\PostRebuildEvent.

Using contextual links with component content

Component content may render the same content multiple times on the same page which makes in context editing not working. In order to have in context editing with component content you need to apply this core patch:

Using entity clone module

In order to be able to clone Site Studio layout fields when cloning a content entity, you need to apply this entity_clone module patch


Run something like: vendor/bin/phpunit -c docroot/core/phpunit.xml.dist --testsuite=unit --group Cohesion
