dorm_mongo_database adapts dORM repositories to MongoDB through mongo_dart. It accepts an application-owned opened Db and does not manage its lifecycle.

Backend and runtime

The backend is MongoDB through mongo_dart. It requires a Dart runtime compatible with dart:io.

Install

dart pub add dorm_framework
dart pub add dorm_mongo_database
dart pub add mongo_dart
dart pub add dorm_annotations
dart pub add --dev dorm_generator
dart pub add --dev build_runner

The package requires a Dart runtime compatible with dart:io.

Create the engine and Dorm facade

import 'package:mongo_dart/mongo_dart.dart';
import 'package:dorm_mongo_database/dorm_mongo_database.dart';

final Db database = Db('[PLACEHOLDER: MongoDB URI]');
await database.open();

try {
  final engine = Engine(database);
  final dorm = Dorm(engine);
  // Use generated repositories here.
} finally {
  await database.close();
}

The application opens and closes Db. Reusing the same Engine and Db keeps all repositories connected to the same database.

Use repositories

final User user = await dorm.users.repository.put(
  Creation.auto(
    dependency: const UserDependency(),
    data: UserData(name: 'Ada'),
  ),
);

await dorm.users.repository.push(user.copyWith(name: 'Ada Lovelace'));

Identities

The engine stores dORM identities in fields declared by EntitySchema. It does not convert the identity to MongoDB ObjectId and does not use MongoDB _id as the dORM identity.

Creation.auto generates UUID strings for supported simple identities. Creation.explicit supplies the final identity. push and pushAll use replacement upserts.

Filters, pages, and relationships

The engine supports framework filters, sorting, offset pagination, and all framework relationship forms. Relationship fallbacks can perform multiple MongoDB reads.

Streams

pull and pullAll emit the initial read only. Change streams are not exposed by the dORM API.

Transactions

The engine does not implement TransactionalDorm or MongoDB sessions.

Schema, errors, and limitations

The engine does not implement TransactionalDorm, MongoDB sessions, aggregation, index management, native selectors, schema generation, or migrations.

The application owns collection setup, indexes, authentication, and database permissions.

Run the example

See the package example for the MongoDB URI, connection lifecycle, generation, and Dart commands.
