ASP.NET MVC Example

[martosource]

Is there a complete example of using MediaR with ASP.NET MVC including the decorator pattern pipeline for validation, authorisation?

[jbogard]

No, but I'm working on it. Looking at converting the MVC sample app to using it from MS.

First: Thanks for a great series of blog posts and a simple, easy to understand Mediator.

I would love to see an example with (domain) event dispatching as well. I'm working on a similar project just to learn the pattern (https://github.com/jenspettersson/Mediocr - partly a shameless clone ;)) where I'm struggling a bit with how to track and dispatch events from domain entities.

I'm using RavenDb and for now I wrapped the session with a... generic repository... that also keeps the requested entities in it's own UoW so I can access them easily later... It doesn't feel... perfect.

Thanks Jimmy.

If you are able to set up and start the conversion of a MVC sample app, I am more than happy to put the work in to complete it.

I also could help the sample, but we do need something to follow along, so lets us know when you do have something. Another question regarding your post: http://lostechies.com/jimmybogard/2013/12/19/put-your-controllers-on-a-diet-posts-and-commands/

you said: "So why two methods? Fairly simple – it’s a bit easier to deal with separate pipelines for queries and commands, as the potential extensions for these two pipelines might be different. I also might have different rules applied and so on."

But as far as I checked mediatR, you only have one type to handle and not one for queries and other for commands. Am I wrong ? Or do you mind explaining why going in this path ?

[jbogard]

On the queries/command thing - I just changed my mind. There wasn't any difference between the two, I could control it more easily with an ICommand or IQuery that I define.

Thanks for the feedback, I also think your line of thinking is better. It is much easier to deal with side effects than all the code necessary to keep it 100% separating between query and commands.

Hey Jimmy, any update on the MVC sample?

[jbogard]

Does the Web API example help at all? It would work for MVC too.

[getuliojr]

I have a complete working version with OWIN + MediatR + Autofac + Web Api 2 and the basic test it went just fine.

[jbogard]

@getuliojr if you're down for it, i'd love a PR that does something similar with what I did for StructureMap. Big ask though, I know

[mreyeros]

That works for me!
