MicroBus: In-Process Mediator

I’ve blogged about the mediator pattern a lot.  Primarily because it’s been a good fit in several of the applications I’ve developed over the last few years. Mediator Pattern For those completely unfamiliar with the mediator pattern, here’s a brief summary: With the mediator pattern, communication between objects is encapsulated with a mediator object. Objects no longer communicate directly with each other, but instead communicate through the mediator. This reduces the dependencies between communicating objects, thereby lowering the coupling. Libraries I’ve written my own implementations of the mediator library from project to project.  Once I finally found the MediatR library, I’ve pretty… Read More »MicroBus: In-Process Mediator

Mediator between Integration Boundaries

If you have followed my Fat Controller CQRS Diet series, you will see that I use the mediator pattern. More specifically I use MediatR library in all the code examples. I recently gave a talk at CodeMash 2017 with the same title.   It went a bit more in depth about why and where I use the mediator pattern. Integration Boundary I want to decouple my application from the framework I’m using. The mediator pattern is one way of achieving that. My code should be be my code.  Not littered through framework code. Generally, I don’t want to have any dependencies on MVC, Web API,… Read More »Mediator between Integration Boundaries

Conference Speaking Experience: CodeMash 2017

At some point in 2016 I decided I wanted to submit talks to a few large conferences.  I’ve done talks at various small user groups, but nothing more than 30 people. The main reason to submit to larger conferences was just for the new experience.  It’s something that is completely out of my comfort zone to speak in front of a large group. I really wanted to see if speaking at conferences was something I would enjoy or not. Although I’ve realized that it’s really easy for me to talking about software and especially the areas that I’ve grown to… Read More »Conference Speaking Experience: CodeMash 2017
