## Introduction
This PR introduces "TwentyORM," a custom ORM module designed to
streamline database interactions within our workspace schema, reducing
the need for raw SQL queries. The API mirrors TypeORM's to provide a
familiar interface while integrating enhancements specific to our
project's needs.
To facilitate this integration, new decorators prefixed with `Workspace`
have been implemented. These decorators are used to define entity
metadata more explicitly and are critical in constructing our schema
dynamically.
## New Features
- **Custom ORM System**: Named "TwentyORM," which aligns closely with
TypeORM for ease of use but is tailored to our application's specific
requirements.
- **Decorator-Driven Configuration**: Entities are now configured with
`Workspace`-prefixed decorators that clearly define schema mappings and
relationships directly within the entity classes.
- **Injectable Repositories**: Repositories can be injected similarly to
TypeORM, allowing for flexible and straightforward data management.
## Example Implementations
### Decorated Entity Definitions
Entities are defined with new decorators that outline table and field
metadata, relationships, and constraints. Here are examples of these
implementations:
#### Company Metadata Object
```typescript
@WorkspaceObject({
standardId: STANDARD_OBJECT_IDS.company,
namePlural: 'companies',
labelSingular: 'Company',
labelPlural: 'Companies',
description: 'A company',
icon: 'IconBuildingSkyscraper',
})
export class CompanyObjectMetadata extends BaseObjectMetadata {
@WorkspaceField({
standardId: COMPANY_STANDARD_FIELD_IDS.name,
type: FieldMetadataType.TEXT,
label: 'Name',
description: 'The company name',
icon: 'IconBuildingSkyscraper',
})
name: string;
@WorkspaceField({
standardId: COMPANY_STANDARD_FIELD_IDS.xLink,
type: FieldMetadataType.LINK,
label: 'X',
description: 'The company Twitter/X account',
icon: 'IconBrandX',
})
@WorkspaceIsNullable()
xLink: LinkMetadata;
@WorkspaceField({
standardId: COMPANY_STANDARD_FIELD_IDS.position,
type: FieldMetadataType.POSITION,
label: 'Position',
description: 'Company record position',
icon: 'IconHierarchy2',
})
@WorkspaceIsSystem()
@WorkspaceIsNullable()
position: number;
@WorkspaceRelation({
standardId: COMPANY_STANDARD_FIELD_IDS.accountOwner,
label: 'Account Owner',
description: 'Your team member responsible for managing the company account',
type: RelationMetadataType.MANY_TO_ONE,
inverseSideTarget: () => WorkspaceMemberObjectMetadata,
inverseSideFieldKey: 'accountOwnerForCompanies',
onDelete: RelationOnDeleteAction.SET_NULL,
})
@WorkspaceIsNullable()
accountOwner: WorkspaceMemberObjectMetadata;
}
```
#### Workspace Member Metadata Object
```typescript
@WorkspaceObject({
standardId: STANDARD_OBJECT_IDS.workspaceMember,
namePlural: 'workspaceMembers',
labelSingular: 'Workspace Member',
labelPlural: 'Workspace Members',
description: 'A workspace member',
icon: 'IconUserCircle',
})
@WorkspaceIsSystem()
@WorkspaceIsNotAuditLogged()
export class WorkspaceMemberObjectMetadata extends BaseObjectMetadata {
@WorkspaceField({
standardId: WORKSPACE_MEMBER_STANDARD_FIELD_IDS.name,
type: FieldMetadataType.FULL_NAME,
label: 'Name',
description: 'Workspace member name',
icon: 'IconCircleUser',
})
name: FullNameMetadata;
@WorkspaceRelation({
standardId: WORKSPACE_MEMBER_STANDARD_FIELD_IDS.accountOwnerForCompanies,
label: 'Account Owner For Companies',
description: 'Account owner for companies',
icon: 'IconBriefcase',
type: RelationMetadataType.ONE_TO_MANY,
inverseSideTarget: () => CompanyObjectMetadata,
inverseSideFieldKey: 'accountOwner',
onDelete: RelationOnDeleteAction.SET_NULL,
})
accountOwnerForCompanies: Relation
<CompanyObjectMetadata[]>;
}
```
### Injectable Repository Usage
Repositories can be directly injected into services, allowing for
streamlined query operations:
```typescript
export class CompanyService {
constructor(
@InjectWorkspaceRepository(CompanyObjectMetadata)
private readonly companyObjectMetadataRepository: WorkspaceRepository<CompanyObjectMetadata>,
) {}
async companies(): Promise<CompanyObjectMetadata[]> {
// Example queries demonstrating simple and relation-loaded operations
const simpleCompanies = await this.companyObjectMetadataRepository.find({});
const companiesWithOwners = await this.companyObjectMetadataRepository.find({
relations: ['accountOwner'],
});
const companiesFilteredByLinkLabel = await this.companyObjectMetadataRepository.find({
where: { xLinkLabel: 'MyLabel' },
});
return companiesFilteredByLinkLabel;
}
}
```
## Conclusions
This PR sets the foundation for a decorator-driven ORM layer that
simplifies data interactions and supports complex entity relationships
while maintaining clean and manageable code architecture. This is not
finished yet, and should be extended.
All the standard objects needs to be migrated and all the module using
the old decorators too.
