  ABP Framework provides flexible support for implementing the CQRS (Command Query Responsibility Segregation) pattern, but it does not enforce it by default. ABP's architecture, especially its application service layer, naturally aligns with CQRS principles by encouraging the separation of commands (write operations) and queries (read operations).

  • You can implement CQRS in ABP by creating separate application services or methods for commands and queries.
  • ABP does not provide a built-in CQRS library, but it is compatible with popular .NET CQRS libraries such as MediatR. You can integrate MediatR or similar libraries into your ABP project for more advanced CQRS scenarios.
  • ABP's modular and DDD-friendly structure makes it easy to organize your code according to CQRS best practices.

  Example: Using MediatR in an ABP module

  [DependsOn(typeof(AbpAspNetCoreMvcModule))]
  public class MyModule : AbpModule
  {
      public override void ConfigureServices(ServiceConfigurationContext context)
      {
          context.Services.AddMediatR(typeof(MyModule).Assembly);
      }
  }
  

  You can then define your command and query handlers as usual with MediatR.

  The MediatR Library is known for its CQRS pattern, but do you have any suggestions for using the CQRS pattern without using this library?
