Introduction

ImmediatePlatform offers libraries that make implementing the Vertical Slice Architecture, CQRS pattern and Validation in .NET easier. You can think of the ImmediatePlatform suite as an alternative to MediatR/Mediator, FluentValidation and ASP.NET Core Minimal APIs/Controllers. Because the suite is made with modularity in mind, all of the libraries are opt-in and can be mixed and matched with other solutions (e.g. ASP.NET Core Controllers + Immediate.Handlers + FluentValidation). Please see our full cookbook for all integration examples.

Here is a full list of what each library has to offer:

# Immediate.Handlers

• Implementation of the mediator pattern in .NET using source-generation.
• Support for implementing the Command and Query Responsibility Segregation (CQRS) pattern with minimal boilerplate.
• Support for addressing cross-cutting concerns via behaviors.
• All pipeline behaviors are determined and the call-tree built at compile-time; meaning that all dependencies are enforced via compile-time safety checks.
• Behaviors and dependencies are obtained via DI at runtime based on compile-time determined dependencies.
• Implementation that does not rely on the service locator anti-pattern.

# Immediate.Apis

• Source generator for Minimal APIs for Immediate.Handlers
• Allows for easily mapping handlers to endpoints

# Immediate.Validations

• Source generator for validating Immediate.Handlers handlers parameters
• Built for maximum performance and minimal boilerplate validation
