## Summary
Completes the migration of the frontend styling system from **Emotion**
(`@emotion/styled`, `@emotion/react`) to **Linaria** (`@linaria/react`,
`@linaria/core`), a zero-runtime CSS-in-JS library where styles are
extracted at build time.
This is the final step of the migration — all ~494 files across
`twenty-front`, `twenty-ui`, `twenty-website`, and `twenty-sdk` are now
fully converted.
## Changes
### Styling Migration (across ~480 component files)
- Replaced all `@emotion/styled` imports with `@linaria/react`
- Converted runtime theme access patterns (`({ theme }) => theme.x.y`)
to build-time `themeCssVariables` CSS custom properties
- Replaced `useTheme()` hook (from Emotion) with
`useContext(ThemeContext)` where runtime theme values are still needed
(e.g., passing colors to non-CSS props like icon components)
- Removed `@emotion/react` `css` helper usages in favor of Linaria
template literals
### Dependency & Configuration Changes
- **Removed**: `@emotion/react`, `@emotion/styled` from root
`package.json`
- **Added**: `@wyw-in-js/babel-preset`, `next-with-linaria` (for
twenty-website SSR support)
- Updated Nx generator defaults from `@emotion/styled` to
`@linaria/react` in `nx.json`
- Simplified `vite.config.ts` (removed Emotion-specific configuration)
- Updated `twenty-website/next.config.js` to use `next-with-linaria` for
SSR Linaria support
### Storybook & Testing
- Removed `ThemeProvider` from Emotion in Storybook previews
(`twenty-front`, `twenty-sdk`)
- Now relies solely on `ThemeContextProvider` for theme injection
### Documentation
- Removed the temporary `docs/emotion-to-linaria-migration-plan.md`
(migration complete)
- Updated `CLAUDE.md` and `README.md` to reflect Linaria as the styling
stack
- Updated frontend style guide docs across all locales
## How it works
Linaria extracts styles at build time via the `@wyw-in-js/vite` plugin.
All expressions in `styled` template literals must be **statically
evaluable** — no runtime theme objects or closures over component state.
- **Static styles** use `themeCssVariables` which map to CSS custom
properties (`var(--theme-color-x)`)
- **Runtime theme access** (for non-CSS use cases like icon `color`
props) uses `useContext(ThemeContext)` instead of Emotion's `useTheme()`
# Introduction
## Centralize system field definitions
- Extract a single `PARTIAL_SYSTEM_FLAT_FIELD_METADATAS` constant as the
source of truth for all 8 system fields (`id`, `createdAt`, `updatedAt`,
`deletedAt`, `createdBy`, `updatedBy`, `position`, `searchVector`),
eliminating duplication across custom object and standard app field
builders
- Refactor `buildDefaultFlatFieldMetadatasForCustomObject` to use the
shared constant via a new `buildObjectSystemFlatFieldMetadatas` helper
## Mark system fields as `isSystem: true`
- Fields `id`, `createdAt`, `updatedAt`, `deletedAt`, `createdBy`,
`updatedBy`, `position`, `searchVector` are now properly flagged as
system fields across all standard objects and custom object creation
- Standard app field builders for all ~30 standard objects updated to
set `isSystem: true` on `createdAt`, `updatedAt`, `deletedAt`,
`createdBy`, `updatedBy`
- System-only standard objects (blocklist, calendar channels, message
threads, etc.) now also include `createdBy`, `updatedBy`, `position`,
`searchVector` field definitions that were previously missing
## Validate system fields on object creation
- New transversal validation (`crossEntityTransversalValidation`) runs
after all atomic entity validations in the build orchestrator, ensuring
all 8 system fields are present with correct `type` and `isSystem: true`
when an object is created
- New `buildUniversalFlatObjectFieldByNameAndJoinColumnMaps` utility to
resolve field names to universal identifiers for a given object
- New exception codes: `MISSING_SYSTEM_FIELD` and `INVALID_SYSTEM_FIELD`
on `ObjectMetadataExceptionCode`
## Protect system fields and objects from mutation
- Field validators now block update/delete of `isSystem` fields by
non-system callers (`FIELD_MUTATION_NOT_ALLOWED`)
- Object validators now block update/delete of `isSystem` objects by
non-system callers
- `POSITION` and `TS_VECTOR` field type validators replaced: instead of
rejecting creation outright, they now validate that the field is named
correctly (`position` / `searchVector`) and has `isSystem: true`
## Distinguish `isSystemBuild` from `isCallerTwentyStandardApp`
- New `isCallerTwentyStandardApp` utility checks whether the caller's
`applicationUniversalIdentifier` matches the twenty standard app
- Name-sync logic (`isFlatFieldMetadataNameSyncedWithLabel`,
`areFlatObjectMetadataNamesSyncedWithLabels`) refactored to use
`isCallerTwentyStandardApp` for custom suffix decisions, keeping
`isSystemBuild` for mutation permission checks
- `WorkspaceMigrationBuilderOptions` type updated to include
`applicationUniversalIdentifier`
## Adapt frontend filtering
- New `HIDDEN_SYSTEM_FIELD_NAMES` constant (`id`, `position`,
`searchVector`) and `isHiddenSystemField` utility to only hide truly
internal fields while keeping user-facing system fields (`createdAt`,
`updatedAt`, `deletedAt`, `createdBy`, `updatedBy`) visible in the UI
- ~20 frontend files updated to replace `!field.isSystem` checks with
`!isHiddenSystemField(field)` across record index, settings, data model,
charts, workflows, spreadsheet import, aggregations, and role
permissions
## Add 1.19 upgrade commands
- **`backfill-system-fields-is-system`**: Raw SQL command to set
`isSystem = true` on existing workspace fields matching system field
names, and fix `position` field type from `NUMBER` to `POSITION` for
`favorite`/`favoriteFolder` objects. Includes proper cache invalidation.
- **`add-missing-system-fields-to-standard-objects`**: Codegen'd
workspace migration to create missing `position`, `searchVector`,
`createdBy`, `updatedBy` fields on standard objects that didn't
previously have them. Runs via `WorkspaceMigrationRunnerService` in a
single transaction with idempotency check. **Known limitation**: assumes
all standard objects exist and are valid in the target workspace.
## Add `universalIdentifier` for system fields in standard object
constants
- `standard-object.constant.ts` updated to include `universalIdentifier`
for `createdBy`, `updatedBy`, `position`, and `searchVector` across all
standard objects
- `fieldManifestType.ts` updated to support the new field manifest shape
## System relation
Completely removed and backfilled all `isSystem` relation to be false
false
As we won't require an object to have any relation system fields
## Add integration tests
- New test suite `failing-sync-application-object-system-fields`
covering: missing system fields, wrong field types (`id` as TEXT,
`createdAt` as TEXT, `position` as TEXT), system field deletion
attempts, and system field update attempts
- New test utilities: `buildDefaultObjectManifest` (builds an object
manifest with all 8 system fields) and `setupApplicationForSync`
(centralizes application setup)
- Existing successful sync test updated to verify system fields are
created with correct properties
## Next step
Make the builder scope the compared entity to be the currently built app
+ nor twenty standard app
In this PR
- Content tab for marketplace apps and installed apps: complies with
[figma](https://www.figma.com/design/xt8O9mFeLl46C5InWwoMrN/Twenty?node-id=34845-126856);
addition of field section showing fields added to standard objects;
initiative: arrow opens a sub-table of fields rows. (suggested because
1/ for marketplace apps we cannot redirect to the actual object page in
settings since the object does not exist yet in the workspace 2/ since
we dont have an quick "go back to application page" option, it can be
annoying to be redirected to a different setting page when we just want
to look at the content of the app objects)
- Permission tab for marketplace apps and installed apps
- left to do - settings tab (in another PR)
There are breaking changes but it's behind a feature flag not exposed
(access to marketplace) so not problematic
marketplace apps
https://github.com/user-attachments/assets/4c660101-50fc-47ce-b90a-8d6f17db5e74
installed apps
https://github.com/user-attachments/assets/c9229ee1-e75f-4cad-8766-758b2c5b37b4
Closes [1918](https://github.com/twentyhq/core-team-issues/issues/1918).
- For the first point in the issue, we just show the deactivated entries
along with the deactivated text.
---
- For the second point, we show a banner and control the
enabled/disabled state of save button depending on whether we're
allowing the user to create table with the typed name.
- For example, we do not want to allow the user to create a table with
reserved name, so we disable the save button without showing a banner.
- Similarly, we do not want the user to create a table with a name that
already exists in the database. In this case, we show a banner and we
also disable the save button.
- Finally, we do not want to allow the user to create a table where
singular and plural name are the same. Therefore, we disable the save
button for names like `works`.
---
- For the third point, if we add the delete button, it logically means
that we allow the user to delete a custom object/field even it has not
been deactivated yet, so did that.
- Upon deleting the object/field, if we wait for the metadata to refetch
before we navigate, this is what we see because the path does not exist
any longer after deletion and we're waiting for refetch on the path
until we navigate away.
https://github.com/user-attachments/assets/dbe0569c-db88-4285-851f-22551b1ca81e
- To avoid this page from appearing, I replaced awaiting refetch to not
awaiting refetch and redirecting while the refetch happens in the
background.
- Therefore, when we delete something, there is a slight delay for when
it is actually cleared out from the list, but the Not Found view does
not appear on the screen.
https://github.com/user-attachments/assets/47f49579-ce51-4d6a-b857-72046247bb4b
- I tried optimistically removing the object/field from the metadata,
but it leads to some issues (crashes the app) and I have not been able
to find a solution for it yet.
- Therefore, instead of getting stuck at perfection and blocking myself,
I stopped getting into the issue further and created this PR by ensuring
that the desired functionality works.
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> Display deactivated objects/fields by default, add delete actions with
confirmation, and unify metadata name computation (auto-suffix reserved
keywords) across front/back with conflict checks in object creation.
>
> - **Frontend (Settings/Data Model)**:
> - **Visibility/UX**: Show `Deactivated` labels for objects/fields;
filters default to include inactive (`showDeactivated`/`showInactive`
true); replace field action dropdown with chevron link.
> - **Delete flows**: Add delete buttons for custom objects/fields with
confirmation modals and background refetch to avoid Not Found flashes.
> - **Creation/Edit validation**: Add name conflict detection banner in
`SettingsDataModelObjectAboutForm` and disable Save on conflicts;
simplify `metadataLabelSchema` to use computed name; form fields
validate on change and sync API names.
> - **Shared (twenty-shared/metadata)**:
> - Add `computeMetadataNameFromLabel` util (slugify+camelCase) and
`RESERVED_METADATA_NAME_KEYWORDS`; auto-append `Custom` to reserved
names; export constants/utilities.
> - **Backend**:
> - Migrate to shared `computeMetadataNameFromLabel`; update validators
to use shared reserved keywords with new messages; allow deletion of
active custom fields/objects (keep standard guards); adjust
services/decorators accordingly.
> - **Tests/Stories**:
> - Update unit/integration snapshots for new reserved-name messages and
behaviors; add missing i18n/router decorators in stories.

# Introduction
closes https://github.com/twentyhq/core-team-issues/issues/591
Same than for `twenty-shared` made in
https://github.com/twentyhq/twenty/pull/11083.
## TODO
- [x] Manual migrate twenty-website twenty-ui imports
## What's next:
- Generate barrel and migration script factorization within own package
+ tests
- Refactoring using preconstruct ? TimeBox
- Lint circular dependencies
- Lint import from barrel and forbid them
### Preconstruct
We need custom rollup plugins addition, but preconstruct does not expose
its rollup configuration. It might be possible to handle this using the
babel overrides. But was a big tunnel.
We could give it a try afterwards ! ( allowing cjs interop and stuff
like that )
Stuck to vite lib app

[#4422](https://github.com/twentyhq/twenty/issues/4422)
Demo:
https://github.com/twentyhq/twenty/assets/155670906/f8027ab2-c579-45f7-9f08-f4441a346ae7
Within the demo, we show the various areas in which the Command/CTRL +
Click functionality works. The table cells within the People and
Companies tab open within both the current tab and new tab due to
unchanged functionality within RecordTableCell. We did this to ensure we
could get a PR within by the end of the week.
In this commit, we ONLY edited EntityChip.tsx. We did this by:
- Removing useNavigate() and handleLinkClick/onClick functionality
- Wrapping InnerEntityChip in an anchor tag
This allowed for Command/CTRL + Click functionality to work. Clickable
left cells on tables, left side menu, and data model navigation
files/areas DID NOT get updated.

## Query depth deprecation
I'm deprecating depth parameter in our graphql query / cache tooling.
They were obsolete since we introduce the possibility to provide
RecordGqlFields
## Refactor combinedFindManyRecordHook
The hook can now take an array of operationSignatures
## Fix tasks issues
Fix optimistic rendering issue. Note that we still haven't handle
optimisticEffect on creation properly
- Set `readOnly` boolean in table row context. Preventing updates and
deletion
- Show page is null for remote objects. No need for complicated design
since this is temporary?
- Relation creations are now behind a feature flag for remote objects
- Refetch objects and views after syncing objects
