Myrtle.Extensions.MicrosoftDependencyInjection 1.2.0

Myrtle

Myrtle is a comprehensive collection of useful extensions and configurations for the official MongoDB C# driver. It aims to simplify and enhance the experience of working with MongoDB in .NET applications.

Features

• Enhanced Configuration: Simplified setup for MongoDB with various conventions and serialization options.
• Dependency Injection: Easy integration with Microsoft.Extensions.DependencyInjection for ASP.NET Core applications.
• Repository Pattern: Generic repository implementation for streamlined data access.
• Data Protection: Support for storing ASP.NET Core Data Protection keys in MongoDB.
• Extensible Architecture: Modular design allowing for easy addition of new features and configurations.

Packages

Package	Version	Description

Installation

You can install Myrtle packages via NuGet Package Manager or .NET CLI.

dotnet add package Myrtle
dotnet add package Myrtle.Extensions.MicrosoftDependencyInjection
dotnet add package Myrtle.AspNetCore.DataProtection.Keys

Key Interfaces and Abstractions

Myrtle provides several key interfaces and abstractions to simplify working with MongoDB:

• IMongoConnection: Represents a connection to a MongoDB server.
• IMongoDatabaseContext: Provides access to a specific MongoDB database.
• IMongoCollectionContext<TDocument>: Represents a MongoDB collection for a specific document type.
• IMongoRepository<TDocument, TId>: Defines a generic repository pattern for MongoDB operations.
• IMongoConfigurationRegistry: Allows registration of custom MongoDB configurations.
• IMongoConfiguration: Represents a specific MongoDB configuration.

Usage

Basic Setup

1. Add MongoDB services to your application's service collection:

services.AddMongoDB(options =>
{
    options.ConnectionString = "mongodb://localhost:27017";
    options.DatabaseName = "MyDatabase";
});

2. Configure MongoDB with custom configurations:

services.AddMongoDBConfigurations(registry =>
{
    registry.AddUtcDateTimeSerialization()
            .AddDecimalSerialization()
            .AddEnumRepresentation()
            .AddIgnoreExtraElements()
            .AddAllConfigurations(); // Adds all available configurations
});

Using the Repository Pattern

1. Define your aggregate root class:

public class User
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
}

2. Create a custom repository by inheriting from MongoRepository<TDocument, TId>:

public class UserRepository : MongoRepository<User, Guid>, IUserRepository
{
    public UserRepository(IMongoCollectionContext<User> collectionContext) 
        : base(collectionContext)
    {
    }

    public async Task<User> FindByEmailAsync(string email)
    {
        var filter = Builders<User>.Filter.Eq(u => u.Email, email);
        return await Collection.Find(filter).FirstOrDefaultAsync();
    }
}

public interface IUserRepository : IMongoRepository<User, Guid>
{
    Task<User> FindByEmailAsync(string email);
}

3. Register your custom repository in the dependency injection container:

services.AddScoped<IUserRepository, UserRepository>();

4. Use the repository in your services:

public class UserService
{
    private readonly IUserRepository _userRepository;

    public UserService(IUserRepository userRepository)
    {
        _userRepository = userRepository;
    }

    public async Task<User> GetUserByIdAsync(Guid id)
    {
        return await _userRepository.GetByIdAsync(id);
    }

    public async Task<User> GetUserByEmailAsync(string email)
    {
        return await _userRepository.FindByEmailAsync(email);
    }

    public async Task AddUserAsync(User user)
    {
        await _userRepository.AddAsync(user);
    }
}

Data Protection Key Storage

To configure ASP.NET Core Data Protection to store keys in MongoDB:

services.AddDataProtection()
    .PersistKeysToMongoDb(mongoClient, "MyDatabase", "DataProtectionKeys");
