DependencyInjectionExtensions

Namespace: RA.Utilities.Authorization.Extensions

The DependencyInjectionExtensions class provides a convenient extension method to simplify the registration of the ICurrentUser service in your application's dependency injection container.

🎯 Purpose​

The DependencyInjectionExtensions class provides a convenient shortcut for registering the services related to the AppUser utility. Its purpose is to simplify the setup process in Program.cs.

Instead of requiring developers to know that AppUser depends on IHttpContextAccessor and registering both manually, this class provides a single extension method, AddCurrentUser(), that handles all the necessary registrations.

This approach:

  1. Reduces Boilerplate: It turns a multi-line setup into a single, declarative call.
  2. Encapsulates Implementation Details: It hides the fact that AppUser needs IHttpContextAccessor, making the setup cleaner and less prone to error.
  3. Promotes Best Practices: By registering the service, it encourages developers to depend on abstractions, not concrete implementations, which is crucial for testability and maintainability.

🧩 Available Extensions​

AddCurrentUser()​

Registers AppUser as the transient. It also registers IHttpContextAccessor, which is required by AppUser to access the current request's user claims.

Usage​

Call AddCurrentUser() in your Program.cs file when configuring your services.

// Program.cs
using RA.Utilities.Authorization.Extensions;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddCurrentUser();

// ... other service registrations

After registration, you can inject AppUser into your controllers and services to access information about the authenticated user.
