FlowX.EntityFrameworkCore 1.1.0

FlowX.EntityFrameworkCore

FlowX.EntityFrameworkCore is an extension package for the FlowX library, providing seamless integration with Entity Framework Core.

Features

• Simplified integration with EF Core repositories.
• Built-in support for Unit of Work patterns.
• Customizable database interaction flows.
• Enhanced error handling for EF Core operations.
• Easy-to-use fluent API for managing EF Core entities.
• Fully supports CRUD flows like CreateOne, CreateMany, GetOne, GetCollection, GetPaged, and GetCounting...

Getting Started

Prerequisites

Ensure you have the following installed:

• .NET 8.0 or higher
• Entity Framework Core
• FlowX

Installation

To install the FlowX.EntityFrameworkCore package, use the following NuGet command:

dotnet add package FlowX.EntityFrameworkCore

Or via the NuGet Package Manager:

Install-Package FlowX.EntityFrameworkCore

Usage

Usage

Below is an example of how to use FlowX.EntityFrameworkCore to handle a CreateSomeThingCommand:

builder.Services.AddFlowX(cfg =>
{
    cfg.AddModelsFromNamespaceContaining<ITestAssemblyMarker>();
    cfg.AddHandlersFromNamespaceContaining<ITestAssemblyMarker>();
    cfg.AddDbContextDynamic<TestDbContext>(options =>
    {
        options.AddDynamicRepositories();
        options.AddDynamicUnitOfWork();
    });
});

Examples:

public sealed class CreateSomeThingHandler(
    ISqlRepository<SomeThing> sqlRepository,
    IMapper mapper,
    IUnitOfWork unitOfWork)
    : EfCommandOneVoidHandler<SomeThing, CreateSomeThingCommand>(sqlRepository, unitOfWork)
{
    protected override ICommandOneFlowBuilderVoid<SomeThing> BuildCommand(
        IStartOneCommandVoid<SomeThing> fromFlow, CreateSomeThingCommand command,
        CancellationToken cancellationToken)
        => fromFlow
            .CreateOne(mapper.Map<SomeThing>(command))
            .WithCondition(_ => None.Value)
            .WithErrorIfSaveChange(SomeErrorDetail());
}

public class UpdateSomeThingHandler(
    ISqlRepository<SomeThing> sqlRepository,
    IUnitOfWork unitOfWork,
    IMapper mapper)
    : EfCommandOneVoidHandler<SomeThing, UpdateSomeThingCommand>(sqlRepository)
{
    protected override ICommandOneFlowBuilderVoid<SomeThing> BuildCommand(
        IStartOneCommandVoid<SomeThing> fromFlow, UpdateSomeThingCommand command,
        CancellationToken cancellationToken)
        => fromFlow
            .UpdateOne(x => x.Id == command.Id)
            .WithSpecialAction(null)
            .WithCondition(_ => None.Value)
            .WithModify(SomeThing => Mapper.Map(command, SomeThing))
            .WithErrorIfNull(MasterDataErrorDetail.SomeThingError.NotFound())
            .WithErrorIfSaveChange(SomeErrorDetail());
}

public sealed class GetSomeThingHandler(ISqlRepository<SomeThing> sqlRepository, IMapper mapper)
    : EfQueryOneHandler<SomeThing, GetSomeThingQuery, SomeThingResponse>(sqlRepository)
{
    protected override IQueryOneFlowBuilder<SomeThing, SomeThingResponse> BuildQueryFlow(
        IQueryOneFilter<SomeThing, SomeThingResponse> fromFlow, GetSomeThingQuery query)
        => fromFlow
            .WithFilter(x => x.Id == query.Id)
            .WithSpecialAction(x => x.ProjectTo<SomeThingResponse>(Mapper.ConfigurationProvider))
            .WithErrorIfNull(SomeErrorDetail());
}

Key Concepts

EF Core Repositories

FlowX.EntityFrameworkCore provides repository abstractions that simplify CRUD operations with EF Core. You can inject ISqlRepository<T> to access database entities directly.

Unit of Work

Unit of Work ensures that all database operations within a command are executed in a single transaction, providing consistency and reliability.

Error Handling

This extension includes advanced error handling tailored for EF Core, enabling you to catch and manage database-related errors gracefully.
