export enum UserRole {
ADMIN = 'ADMIN',
READER = 'READER',
}
class User {
@EnumFallback({
type: UserRole,
fallback: (value: UserRole) => UserRole.READER // if the role is not "ADMIN" or "READER", then the role will be "READER".
})
public role?: UserRole;
}It works with array too:
import { EnumFallback } from '@algoan/nestjs-class-transformers';
export enum UserRole {
ADMIN = 'ADMIN',
READER = 'READER',
}
class User {
@EnumFallback({
type: UserRole,
fallback: (value: UserRole) => UserRole.READER // if an array element is not "ADMIN" or "READER", then the role will be "READER".
})
public roles: UserRole[];
}
