## Summary
- Replaced the `deep-equal` npm package with the existing
`fastDeepEqual` from `twenty-shared/utils` across 5 files in the server
and shared packages
- `deep-equal` was causing severe CPU overhead in the record update hot
path (`executeMany` → `formatTwentyOrmEventToDatabaseBatchEvent` →
`objectRecordChangedValues` → `deepEqual`, called **per field per
record**)
- `fastDeepEqual` is ~100x faster for plain JSON database records since
it skips unnecessary prototype chain inspection and edge-case handling
- Removed the now-unnecessary `LARGE_JSON_FIELDS` branching in
`objectRecordChangedValues` since all fields now use the fast
implementation
- Replace soft-deletion (deletedAt) with isActive boolean for
overridable entities (tabs, widgets, viewFieldGroups, viewFields).
Standard entities are deactivated (isActive: false) when removed from
update payloads, while custom entities are hard-deleted.
- When a viewFieldGroup is deactivated/deleted, its viewFields are
reassigned to the next section by position (or null if none remain).
- Add isActive: true filters to viewFieldGroup and viewField API queries
so deactivated entities are excluded from responses.
Next:
- fields-widget-upsert.service.ts should be refactored a bit
- Add restore logic
This PR fixes a bug which could happen if two people were editing a page
layout at the same time.
If one person deletes a widget or a tab and saves first, and the second
person saves after but doesn't delete this widget or tab, an error is
raised.
This is because, in the backend, a diff is computed to know which tab or
widget to create, update or delete. But the logic was maid without
considering soft deletion. So, when the second person saves, the diff
tries to create the widget or tab which had been soft deleted by the
first use. Since they have the same id, a duplicate primary key error is
raised.
Now we always consider that the last user to save has the truth. So we
restore the tab/widget and update it.
Add a new graphql mutation in the pageLayout resolver to handle page
layout update with tabs and widgets.
Later we will add validation inside the service to check if the page
layout tab structure is correct (for instance check widgets don't
overlap or aren't out of the grid, or to check that they have a correct
configuration ...).
This mutation will be plugged to the save action of the dashboards in
the frontend.
