Nabu.Data.EntityFramework 1.4.0

Nabû is an open-source suite of libraries designed to organize and standardize .NET applications development through streamlined interactions. The suite is divided into three (for now) components:

• Nabu.Core: Provides inversion of control (IoC) helpers that streamline services registration by using attribute tagging.
• Nabu.Data: Provides data manipulation abstraction, encompassing CRUD operations and sophisticated querying using LinQ.
• Nabu.Storage: Provides standardized file manipulation abstractions, catering to local, remote, and cloud-based files.

Latest packages

Installation

Before installing Nabû, make sure to add the custom NuGet source to your configuration.
Open a terminal or command prompt and run the following command:

dotnet nuget add source "https://nuget.kworld.dev/v3/index.json" -n "kworld NuGet"

Now you can install the various components of Nabû with the following commands:

# Nabu.Core
dotnet add package my_awesome_project.csproj Nabu.Core

# Nabu.Data
dotnet add package my_awesome_project.csproj Nabu.Core --version 1.0.0-alpha

dotnet add package my_awesome_project.csproj Nabu.Storage.Local --version 1.0.0-alpha # For local storage
dotnet add package my_awesome_project.csproj Nabu.Storage.Minio --version 1.0.0-alpha # For Minio (Amazon S3) storage

Getting started

Automatic Service Discovery

Nabu.Core introduces automatic service discovery. By tagging interfaces and classes with attributes, the ServiceHelper dynamically finds and uses implementations for services.

Usage

// Example of using attribute ServiceAttribute for service registration
[Service]
public interface IMyService
{
    void DoSomething();
}

public class MyService : IMyService
{
    public void DoSomething()
    {
        // Implementation details
    }
}

public class Main
{
    public void ConfigureServices()
    {
        ServiceHelper serviceHelper = new();
        
        //by using serviceHelper.Context it's possible to precise
        //in wich assemblies or type collections search for implementations and definitions
        //by default it will search in AppDomain.GetAssemblies() (beware lazy-loading !)
        Assembly[] servicesImplementationsAssemblies =
        {
            typeof(MyService).Assembly,
        };
        serviceHelper.Context.WhiteListedDefinitionsTypes.Add(typeof(IMyService));
        serviceHelper.Context.ImplementationsAssemblies.AddRange(servicesImplementationsAssemblies); 
        
        
        //Launch the search of service definitions and theirs implement and then register them.
        serviceHelper.RegisterServices();
        
        using IServiceRegisterProvider provider = ServiceRegistry.BuildServiceProvider();
        
       
        IMyService? service = provider.GetService<IMyService>();
        service.DoSomething();
    }
}

IDao: Data manipulation Interface

Nabu.Data provide the IDao interface in order to standardize data CRUD.

Usage

public class User : IEntity
{
    public string Id { get; set; } = Guid.NewGuid().ToString();
    public DateTime Creation { get; set; } = DateTime.UtcNow;
    public DateTime Update { get; set; } = DateTime.UtcNow;
    
    public string? Name { get; set; }
    public int Age { get; set; }
    
    public List<Car> Cars { get; set; } = new();
}


public class Car : IEntity
{
    public string Id { get; set; } = Guid.NewGuid().ToString();
    public DateTime Creation { get; set; } = DateTime.UtcNow;
    public DateTime Update { get; set; } = DateTime.UtcNow;

    public string? Imatriculation { get; set; }
    public string? Model { get; set; }
    
    [ForeignKey("OwnerId")]
    public User? Owner {get;set;}
    public string? OwnerId { get; set; }
}

public class Main
{
    public async Task ExempleMethod()
    {
        ServiceHelper serviceHelper = new();
        //Configuration
        //...
        await using IServiceRegisterProvider provider = ServiceRegistry.BuildServiceProvider();
        await using IServiceRegistryScope scope = provider.CreateAsyncScope();
        await using IServiceRegisterProvider scopeProvider = scope.ServiceProvider;
        
        IDao? dao = scopeProvider.GetService<IDao>();
        
        
        User cosette = new() { Name = "Cosette", Age = 25 };
        User jean = new() { Name = "Jean Valjean", Age = 55 };
        
        cosette = await dao.AddAsync(cosette);
        jean = await dao.AddAsync(jean);
        
        Car car = new() { Imatriculation = $"CCC-BBB-1", OwnerId = null};
        await dao.AddAsync(car);
        
        Car car2 = new() { Imatriculation = $"CCC-BBB-2", OwnerId = cosette.Id};
        await dao.AddAsync(car2);
        
        car.OwnerId = cosette.id;
        await dao.UpdateAsync(car);
        
        ISpecification<Car> carSpecification = new Specification<Car> { Criteria = c => c.OwnerId == cosette.Id };
        carSpecification.OrderBy(c => c.Creation).ThenBy(c => c.Update);
        
        var dbCars = await dao.ListAllAsync(carSpecification);
        
    }
}

Why "Nabû" ?

Nabû (Akkadian: cuneiform: 𒀭𒀝) is the name of and old Mesopotamian God.
In ancient cultures, Nabû was revered as a deity associated with wisdom, scholarship, and the recording of informations. Nabû's symbols included a stylus resting on a tablet.

By adopting those name and symbols, this suite of libraries refers, in a cool way, to the the art of writing and recording of informations.
