Getting started

The easiest way to help develop Flow is to use MediaWiki-Vagrant.

Enable the Flow role (you may need to run vagrant provision afterwards).

If you do not use MediaWiki-Vagrant, you will need to set up all the required dependencies listed at https://www.mediawiki.org/wiki/Extension:Flow#Dependencies .

You can find the Collaboration team, and other volunteers who maintain Flow, in #wikimedia-tech on Libera Chat.

Libraries

Flow primarily uses two libraries, OOUI/OOUI PHP and Handlebars. Handlebars is a templating language used on both the client and server.

When developing, it is recommended to set: $wgFlowServerCompileTemplates = true;

so templates are automatically updated.

Before committing a change that affects templates, run:

make compile-lightncandy

to make sure all the PHP templates are updated.
