Loxia - Your Database, fluent in Dart

Today, we are thrilled to unveil Loxia, a lightweight and flexible Object-Relational Mapping (ORM) library for Dart. Loxia is designed to simplify database interactions and management of data models, providing a seamless experience for developers working with relational data in their Dart applications.

Why Loxia?

When Avesbox started, we wanted to create tools that empower developers to build better applications. Loxia is another step in that direction. It offers a clean and intuitive API for defining data models, managing database schemas, and performing CRUD operations with ease.

Loxia is built with a focus on:

• Simplicity: Loxia abstracts away the complexities of database interactions, allowing you to focus on your application logic.
• Flexibility: Whether you're working with SQLite, PostgreSQL, or MySQL, Loxia provides a consistent API that adapts to your chosen database engine.
• Type Safety: Loxia leverages Dart's type system to ensure that your data models are well-defined and that your database interactions are safe and predictable.
• Migrations: Loxia includes a powerful migration system that helps you evolve your database schema over time without losing data.

Getting Started

To get started with Loxia, simply add it to your pubspec.yaml:

dependencies:
  loxia: ^1.0.0

Then, you can define your data models using Loxia's annotations:

import 'package:loxia/loxia.dart';
part 'user.g.dart';

@EntityMeta()
class User extends Entity {
  @PrimaryKey()
  final int id;

  @Column()
  final String name;

  @Column()
  final String email;

  User(this.id, this.name, this.email);

  static EntityDescriptor<User, UserPartial> get entity => 
    $UserEntityDescriptor;
}

Let's execute build_runner to generate the necessary code:

dart run build_runner build

The necessary code will be generated. Let's now add it to the datasource and perform some operations:

import 'package:loxia/loxia.dart';

Future<void> main() async {
  final ds = DataSource(
    SqliteDataSourceOptions(
      path: 'example.db',
      entities: [User.entity],
    ),
  );
  await ds.init();
  final users = ds.getRepository<User>();
  await users.insert(
    UserInstertDto(name: 'Francesco', email: 'francesco@example.com')
  );
  await ds.dispose();
}

Now you can run your application, and Loxia will handle the database interactions for you! Explore the documentation for more advanced features like migrations, relationships, and custom queries here.

Loxia is still in its early stages, and we are excited to continue developing it with the help of the community. We welcome contributions, feedback, and suggestions to make Loxia the best ORM for Dart developers.
