Hello everyone,
The Design Systems Team is pleased to announce that ResourceLoader now
supports basic code splitting for Codex
<https://www.mediawiki.org/wiki/Codex> components. The way this works is
similar to how Codex icons already work: you list the components you need
in your ResourceLoader module definition, and only the components you need
will be bundled. This should be helpful for performance, reducing the
amount of code that is loaded by loading only the components your feature
needs, not the entire library. Most new and existing uses of Codex should
be able to use this feature. If you maintain code that uses Codex, we
recommend trying this out!
There's documentation for how to use this feature on the Codex page on
mediawiki.org
<https://www.mediawiki.org/wiki/Codex#Requiring_Codex_components_in_MediaWiki_and_extensions>,
and you can also look at the CodexExample extension
<https://gitlab.wikimedia.org/repos/design-systems/CodexExample> for a more
complete example of how to use this feature. If you have any questions, or
run into any issues trying to use this feature, we're here to help, feel
free to reply to this email or post on the Codex talk page on
mediawiki.org
<https://www.mediawiki.org/wiki/Talk:Codex>.
So far we have only implemented the most basic iteration of code splitting.
We plan on building some more advanced features to help with deduplication
of components as well. For more details about our plans, see the epic task
