## Refactor page layout widget types into shared package and expose from
SDK
### Why
Widget configuration types were defined only on the server, forcing SDK
consumer apps to import from deep internal `twenty-shared/dist` paths —
fragile and breaks on structural changes. Server DTOs also had no
compile-time guarantee they matched the canonical types.
### What changed
- **`twenty-shared`**: Migrated `ChartFilter`, `GridPosition`,
`RatioAggregateConfig` and all 20 widget configuration variants into
`twenty-shared/types`. `PageLayoutWidgetConfiguration` (base, with
`SerializedRelation`) and `PageLayoutWidgetUniversalConfiguration`
(derived via `FormatRecordSerializedRelationProperties`) are now the
single source of truth.
- **`twenty-sdk`**: Re-exported `AggregateOperations`,
`ObjectRecordGroupByDateGranularity`, `PageLayoutTabLayoutMode`, and
`PageLayoutWidgetUniversalConfiguration` so consumer apps import from
`twenty-sdk` directly.
- **`twenty-server`**: All widget DTOs now `implements` their shared
type for compile-time enforcement. Added helpers to convert nested
`fieldMetadataId` ↔ `fieldMetadataUniversalIdentifier` inside chart
filters. Removed redundant local type re-exports.
# Introduction
In preparation of the workspace agnostic builder, we're migrating
`FlatEntityMaps` to be universal identifier oriented and based
As in the builder context there're won't be any ids at all
Please also note that the FlatEntity is a UniversalFlatEntity superset
From
```ts
import { type SyncableFlatEntity } from 'src/engine/metadata-modules/flat-entity/types/flat-entity-from.type';
export type FlatEntityMaps<T extends SyncableFlatEntity> = {
byId: Partial<Record<string, T>>;
idByUniversalIdentifier: Partial<Record<string, string>>;
universalIdentifiersByApplicationId: Partial<Record<string, string[]>>;
};
```
To
```ts
export type FlatEntityMaps<
T extends SyncableFlatEntity | UniversalSyncableFlatEntity,
> = {
byUniversalIdentifier: Partial<Record<string, T>>;
universalIdentifierById: Partial<Record<string, string>>;
universalIdentifiersByApplicationId: Partial<Record<string, string[]>>; // this might make more sense to be migrated to universalIdentifiersByApplicationUniversalIdentifier but it's the main topic of this PR
};
```
## Low level maps tools
Had to refactor find | create | delete | replace | find-many | get-sub
tools ( through mutations and or throw equivalent )
- Create resolvers for each type of charts which needs data
transformation after the group by operation: Bar Chart, Line Chart and
Pie Chart
- Move all the utils to the backend and refactored some into services
This allows all the computation to be done in the backend, improving
performances in the frontend.
