[MEX] 🐌 Reduce dependency on oojs-ui libraries for mobile
Closed, ResolvedPublic
Actions

Description

Reference parent investigation https://phabricator.wikimedia.org/T400325

MEX unnecessarily loads oojs-ui-widgets through WikibaseQualityConstraints. A proof-of-concept patch exists but needs review comments resolved.

This ticket is focused on MEX and should make the mobile loading time faster.

Acceptance Criteria:

  • oojs-ui-widgets is not loaded in MEX when not required.
  • Conditional loading implemented for extensions (example: QualityConstraints).
  • Page load size is measurably reduced (before/after comparison).
  • No regression in functionality for editing or constraints UI.

Note: a patch has been created in the parent task that should be reviewed.

On Beta wbui2025, mw.loader.getState('oojs-ui') now returns "registered" instead of "ready" \o/

TV: Looks like a working optimization to me. A before and after comparison for the loaded oojs assets.
