Category:Extensions without an image Category:GPL licensed extensionsCategory:All extensions

The GrowthExperiments extension is used by Wikimedia Foundation sites for experiments done by the Growth team. The extension contains features for:

a survey during registration
some improvements to registration confirmation emails
a homepage for inexperienced users with various helpful features, which also serves as an entry point for most other functionality
showing a custom signup page to users who arrive through an outreach campaign
suggesting easy tasks with guidance to new users , including some structured editing experiences based on suggested links and suggested images
a help panel for suggested tasks and for generic editing, providing information and allowing communication with an assigned mentor
features for mentors to better support newcomers
showing information to new users about the impact they are making on the wiki

Integrations

GrowthExperiments integrates with the following extensions (extensions marked as Soft dependency are optional, but the behaviour of GrowthExperiments without those extensions present is not heavily tested):


Extension	Soft/Hard dependency	Description
CentralAuth	Soft dependency	to exclude locked users from the Mentor dashboard
CirrusSearch	Soft dependency	for various search features used during suggested tasks
CommunityConfiguration	Hard dependency	to allow administrators to customise the extension based on their needs
ConfirmEdit	Soft dependency	TBD
Echo	Soft dependency	for informing new users and mentors about various opportunities
EventBus	Soft dependency	to inform Add Image infrastructure about user decisions about recommendations
EventLogging	Soft dependency	to log user interaction for analysis purposes
Flow	Soft dependency	for messaging features ("ask help" dialog on the homepage and in the help panel) when the target page is a Flow page
GuidedTour	Soft dependency	to guide new users through the interface
MobileFrontend	Soft dependency	for showing a mobile-optimized version of various features
PageImages	Soft dependency	for getting the thumbnails showing in the "Surfacing structured tasks"-experiment
PageViewInfo	Soft dependency	for various interface elements trying to explain the user's current or potential impact, most notably the "impact" module on Special:Homepage
Thanks	Soft dependency	to compute the number of Thanks received in User impact data
TimedMediaHandler	Soft dependency	TBD
TextExtracts	Soft dependency	for getting an extract from an article when the descriptions from Wikibase (see above) or Wikibase itself are not available. Also for use in the "Surfacing structured tasks"-experiment
UniversalLanguageSelector	Soft dependency	for language selection in the post-registration survey
VisualEditor	Hard dependency	for a better editing experience when doing suggested tasks
Wikibase	Soft dependency	for getting the descriptions showing in the "Surfacing structured tasks"-experiment
WikimediaMessages	Soft dependency	to populate the list of topics in Suggested edits

The extension also uses some web APIs which are probably unavailable for non-Wikimedia wikis:

Page Content Service for displaying task card information such as a description and an image
Analytics Query Service for interface elements related to impact (this is abstracted away via the PageViewInfo extension on the server-side, but for client-side features that's not always possible)
Add Link for link recommendation tasks
Add Image for image recommendation tasks
