I think the lack of a dominant JavaScript domain model syntax has limited the availability of admin tools like django-admin. Maybe something driven by OpenAPI/Swagger model definitions?

It is ancient and no longer upgraded (and based on angularjs), but I'd argue that ng-admin (https://github.com/marmelab/ng-admin) is the fastest SPA/JavaScript admin framework out there. It is a bit opinionated about paging and filtering (and painful to do moderately complex UI customization), but beyond that I have seen nothing that has come close to the same level of "quickly get CRUD admin UI available" in react/vue land, largely because (similar to django) it had its own domain entity model.

The same team moved from there to react-admin, and looking at a couple of react-admin experiences I've been involved in I'd argue that it wasn't aiming for the same ease of use.
