Usage

Write you entities/interfaces at once
An entity requires an Entity and an Id annotation.

@Entity('person')
class PersonEntity {
    @Id()
    id!: string;
    
    @Property()
    name?: string;
}

Create/update/read from database

declare const connection : AdamantConnectionManager;

const repo = connection.getRepository(PersonEntity);

const person = repo.build({ id: '1', name: 'Jon Doe' });

await repo.create(person); // persist in database

person.name = 'Jane Doe';

await repo.update(person); // update database entry
await repo.upsert(person); // inserts/updates if needed

const personCopy = await repo.read('1'); // personCopy equals person

await repo.delete(personCopy); // marks database entry as deleted (_deleted = true)

Create and resolve relations

@Entity('class')
class ClassEntity {
    @Id()
    id!: string;
    
    @HasMany(Person)
    persons?: Person[];
}

const classRepo = connection.getRepository(ClassEntity);
const personRepo = connection.getRepository(PersonEntity);

const janeDoe = personRepo.build({ id: '1', name: 'Jane Doe' });
const jonDoe = personRepo.build({ id: '2', name: 'Jon Doe' });

await personRepo.bulk.create([ janeDoe, jonDoe ]); // persist multiple entities at once

const cls = classRepo.build({ id: '2a', persons: [ janeDoe, jonDoe ] });

await classRepo.create(cls); // relations will be replace with their id's
