# Introduction
In this PR we're introducing mainly two branded type signatures for both
`JsonbProperty` entities properties and `SerializedRelation` (jsonb
serialized property storing another entity id).
Allowing to dynamically map over them later in order to build universal
`jsonb` `serialized` relations.
## `JsonbProperty`
A branded wrapper type that marks entity properties stored as PostgreSQL
JSONB columns. It adds a phantom brand `__JsonbPropertyBrand__` to
object types while leaving primitives unchanged. The branded key is
optional and typed as never, also omitted when transpiled to
`UniversalFlat`
**Should be used at entities lvl only:**
```typescript
@Column({ type: 'jsonb', nullable: false })
gridPosition: JsonbProperty<GridPosition>;
@Column({ nullable: false, type: 'jsonb', default: [] })
publishedVersions: JsonbProperty<string[]>;
```
## `SerializedRelation`
A branded string type that marks foreign key IDs stored inside JSONB
objects. These are entity references serialized within a JSONB column
rather than being a regular database foreign key.
**Usage in jsonb property generic***
```ts
type FieldMetadataRelationSettings = {
relationType: RelationType;
onDelete?: RelationOnDeleteAction;
joinColumnName?: string | null;
junctionTargetFieldId?: SerializedRelation;
};
```
## `FormatJsonbSerializedRelation<T>`
A transformation type that processes JSONB properties for universal
entity mapping. It:
1. Detects properties with the `JsonbProperty` brand
2. Finds `SerializedRelation` properties
3. Renames them from `*Id` to `*UniversalIdentifier`
4. Removes the brand from the output type ( optional though )
```typescript
// Input: JsonbProperty<{ targetFieldMetadataId: SerializedRelation }>
// Output: { targetFieldMetadataUniversalIdentifier: SerializedRelation }
```
## Result
An example of the dynamic type mapping, through a type-test example
```ts
type SettingsTestCase = UniversalFlatFieldMetadata<
| FieldMetadataType.RELATION
| FieldMetadataType.NUMBER
| FieldMetadataType.TEXT
>['settings']
type SettingsExpectedResult =
| {
relationType: RelationType;
onDelete?: RelationOnDeleteAction | undefined;
joinColumnName?: string | null | undefined;
junctionTargetFieldUniversalIdentifier?: SerializedRelation | undefined;
}
| {
dataType?: NumberDataType | undefined;
decimals?: number | undefined;
type?: FieldNumberVariant | undefined;
}
| {
displayedMaxRows?: number | undefined;
}
| null;
type Assertions = [
Expect<Equal<SettingsTestCase, SettingsExpectedResult>>,
]
```
## Remarks
- Removed duplicated twenty-server and twenty-shared typed
- Removed class validator instances for default value that were not used
at runtime, we will refactor that to add validation across all entities
following a same pattern

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
What You Can Do With Twenty
Please feel free to flag any specific needs you have by creating an issue.
Below are a few features we have implemented to date:
- Personalize layouts with filters, sort, group by, kanban and table views
- Customize your objects and fields
- Create and manage permissions with custom roles
- Automate workflow with triggers and actions
- Emails, calendar events, files, and more
