How to add Auditing in FunctionMonkey?

[imkheong]

Hi James

Thanks for building this framework, appreciate the effort and good thinking.

I have a question regarding Auditing ability shown in this article.

I presume that I need the ICommandingDependencyResolverAdapter resolver or ICommandRegistry registry so I can add the Pre, Post and Execute Dispatch hooks. Is there a way that I can do it in FunctionAppConfiguration currently?

Thanks!

Thanks! I hadn't even seen this functionality in the commanding library!
So I dug around the repos and tested this on my example, seems to work:

using FunctionMonkey.Abstractions;
using AzureFromTheTrenches.Commanding;

public class Configuration : IFunctionAppConfiguration, ICommandingConfigurator
{
    ...
    public ICommandRegistry AddCommanding(ICommandingDependencyResolverAdapter dependencyResolver)
        {
            var registry = dependencyResolver.AddCommanding();
            var auditRootOnly = false;
            dependencyResolver
                .AddPreDispatchCommandingAuditor<ConsoleAuditor>(auditRootOnly)
                .AddPostDispatchCommandingAuditor<ConsoleAuditor>(auditRootOnly)
                .AddExecutionCommandingAuditor<ConsoleAuditor>(auditRootOnly);
            return registry;
        }
}

The key here is the Runtime.cs looks to see if your configuration is ICommandingConfigurator and runs the method. If not, it just runs the AddCommanding() extension on the resolver. Also, it throws an error if you don't run the AddCommanding before adding the auditor. The Add... extensions are in the AzureFromTheTrenches.Commanding namespace.

Thank you very much @abezverkov for the answer! I managed to get it to work, and it works exactly I expected it!
