Rollbar integration for Nancy built on top of Valetude.Rollbar.

So you can report bugs to Rollbar w/out adding dependencies on System.Web like you get in RollbarSharp

Nuget Package Manager

install-package Nancy.Rollbar

There are 6 interfaces with implementations for 3 of them. Filling out the other three is one part of your job.

First thing to do is to create a class that implements IHasAccessToken. The RollbarAccessToken property should return the server side token from Rollbar.

The second thing to do, if you want the person field on your rollbar payload to be filled out right is to implement IPersonFactory. It has a GetPerson method that receives an IUserIdentity and returns a RollbarPerson. This allows you to use your knowledge of how you do Auth in your project to set the Id UserName and Email properties correctly. If you do not fill this out, the person field will be filled out automatically using the Context.CurrentUser.Username as both Id and Username.

The third thing to do is to implement the IRollbarDataScrubber interface. This allows you to exclude any sensitive information from the report data that will be sent along to Rollbar.

The final thing to do is to wire in the error handler. This is done as any OnError hook is done. If you want to wire it in globally you can put the appropriate code into a bootstrapper in an override of ApplicationStartup. My preference is to create an implementation of IApplicationStartup and to let Nancy discover, instantiate, and initialize it:

You are 100% responsible for removing passwords and other sensitive information from the payload that is sent to Rollbar via the IRollbarDataScrubber interface. While they do have some scrubbing that they do, they cannot guess all the various ways you might name fields that you don't want people to see. Nancy.Rollbar does not make any assumptions about the kinds of fields that you want to protect.

using Nancy.Bootstrapper;

namespace Nancy.Rollbar.Tests {
    public class StartupNancyRollbar : IApplicationStartup {
        private IRollbarPayloadFactory _payloadFactory;
        private IRollbarPayloadSender _payloadSender;

        public StartupNancyRollbar(IRollbarPayloadFactory payloadFactory, IRollbarPayloadSender payloadSender) {
            _payloadFactory = payloadFactory;
            _payloadSender = payloadSender;
        }

        public void Initialize(IPipelines pipelines) {
            pipelines.OnError.AddItemToStartOfPipeline((ctx, err) => {
                var payload = _payloadFactory.GetPayload(ctx, err);
                var response = _payloadSender.SendPayload(payload);
                if (response.StatusCode == RollbarResponseCode.Success) {
                    return null; // To Allow the rest of the pipeline to handle the error
                }
                // If you want to return null anyway it might not be a bad idea. You can also check if `StaticConfiguration.IsRunningDebug`
                return "OH NO! ROLLBAR FAILED!";
            });
        }
    }
}
