import { EntityManager } from '@karmaniverous/entity-manager';

declare const entityManager: EntityManager<any>;

const client = new EntityClient({
  entityManager,
  tableName: 'UserTable',
  region: 'local',
});

// One-time table creation (from EntityManager config)
await client.createTable({
  BillingMode: 'PAY_PER_REQUEST',
  ...generateTableDefinition(entityManager),
});

// Put / Get (records; strip keys to get domain)
await client.putItem({ hashKey2: 'h', rangeKey: 'r', a: 1 });
const out = await client.getItem({ hashKey2: 'h', rangeKey: 'r' });
const item = out.Item && client.entityManager.removeKeys('user', out.Item);
