User:Dan-nl/Developing extensions for Wikimedia wikis

Below is a rough outline of the steps needed in order to deploy an extension onto a Wikimedia wiki.

Show community support

• Show community support/desire for the extension to be deployed, if applicable

Community Support can be shown by having an active discussion on the need of the extension on a Wikiproject and document the responses. If there is no active community support, support can be build through discussions and proposals.

Request a component in Bugzilla

• Add a project or component to Bugzilla

Create a tracking bug

Once the new component in Bugzilla has been created, create a tracking bug for the deploy.

• Reporting a new bug or feature request

Create Extension: page

• Create an Extension:<Your extension> page on mediawiki.org

Create Help:Extension: page

• Create a Help:Extension:<Your extension> on mediawiki.org for the end user documentation

Get code in Gerrit

• New repositories

Gerrit review(s)

• Request (and respond to) code review(s) in Gerrit, resulting in an Minimum Viable Product (MVP)
• Depending on the complexity of the code this may go through several cycles of development before an MVP is ready.

Design/Implementation documentation

• use sequence diagrams and prose to describe the design and implementation of the extension; e.g., MetadataDetectHandler
• https://www.websequencediagrams.com/ can be helpful here

Design review

• Request a design review, if applicable

Performance and Architecture review

• Request (and respond to) a performance/arch review
