@tc-libs/database

Layer base Mongo/Mongoose del monorepo.

Il package contiene:

• DatabaseOptionsModule per costruire MongooseModuleOptions
• abstract entity/repository riusabili
• interfacce per query, sessioni, cache e pagination
• costanti e decorator di supporto

DatabaseOptionsModule

Serve per centralizzare la costruzione della connection string Mongo:

DatabaseOptionsModule.register({
  proto: 'mongodb',
  host: '127.0.0.1:27017',
  port: 27017,
  name: 'mydb',
  user: 'mongo',
  password: 'secret',
  debug: false,
});

Poi:

MongooseModule.forRootAsync({
  imports: [DatabaseOptionsModule.register(...)],
  useExisting: DatabaseOptionsService,
});

Repository base

La classe piu importante e DatabaseMongoRepositoryAbstract<Entity, EntityDocument>.

Fornisce:

• CRUD standard
• join/populate opzionale
• returnPlain
• supporto ClientSession
• integrazione cache con @tc-libs/app-cache
• raw() per aggregate pipeline
• startTransaction()

Esempio repository custom

export class UserRepository extends DatabaseMongoRepositoryAbstract<
  UserEntity,
  UserDoc
> {
  protected readonly _logger = new Logger(UserRepository.name);

  constructor(
    @InjectModel(UserEntity.name) model: Model<UserEntity>,
    @InjectConnection() connection: Connection,
    cache: AppCacheService,
  ) {
    super(model, connection, cache);
  }
}

Abstract entity

• DatabaseBaseEntityAbstract
• DatabaseMongoEntityAbstract

Ti evitano di ridefinire sempre _id, createdAt, updatedAt.

Interfacce piu usate

• IDatabaseFindOneOptions
• IDatabaseFindAllOptions
• IDatabaseCreateOptions
• IDatabaseManyOptions
• IDatabaseFindOneAndUpdateOptions
