Allow use of same-shape-adapters ahead of general adapter support in #3464003

Created on 15 July 2025, 4 days ago

Overview

While working on 📌 Improve the front-end DX of Active , I realized that both

that issue's MR's src_with_alternate_widths computed property on the image field type, and
its predecessor's ( ✨ Add automated image optimization to image component Active ) srcset_candidate_uri_template computed property on the image field type

are actually NOT what we should be doing, but it's the pragmatic work-around until we have adapter support: ✨ [later phase] PropShapes' JSON schema must match exactly with FieldType's storage format — what if you want to use another FieldType? Active .

If we ship the beta like this, it’ll mean supporting these computed field properties forever, unless we do a fully automated update path early on, before enormous amounts of content can be created. We know and proved it’s technically possible (see ComponentInputsEvolutionTest::testBlockPluginUpdatePath()), but … ideally we avoid this.

Proposed resolution

Allow adapters that consume a single prop shape and output that same single shape.

This would bypass the need for:

design
UI changes
hopefully any front-end changes
hopefully minimal back-end changes

User interface changes

None.

Discussed in detail with @effulgentsia, I'll spend 2 time-boxed hours on this tomorrow. Given the impact, we agreed to tag it .

That would remove the need to replicate this crutch/work-around in more places, and simultaneously avoids the need to do all of ✨ [later phase] PropShapes' JSON schema must match exactly with FieldType's storage format — what if you want to use another FieldType? Active .

Also, this would allow solving https://git.drupalcode.org/project/experience_builder/-/merge_requests/1..., which @lauriii pointed out yesterday.
