Nancy – A lightweight web framework for .NET

If you like this sort of thing, and enjoy or are curious about F-Sharp, give Suave a look: https://suave.io/

There are two great tutorials for it: https://www.gitbook.com/book/theimowski/suave-music-store/de...

and

which gets more into how suave actually works.

I do a good bit of .Net webservice work and Nancy is my go to solution for throwing up an HTTP API. I've taken the same app from a Windows oriented ASP.net hosted to a Linux/Mono hosted self hosted service with very few changes to the code. Even in the new .Net Core/MVC6 world I think Nancy is a good option to consider given all the middleware and plugins available on NuGet.

Looks like the beta version of Nancy now supports .NET Core.

Last I heard was this: http://thecodejunkie.com/2016/02/22/working-full-time-on-get...

Digging into the code, it looks like the work has been merged in. I haven't seen an official announcement though.

I'll update https://anclafs.com/#web (edit: done)

Don't see the point of Nancy today with the latest MVC6 that can be made really light weight when one needs just a few end points without bloat. You're app can basically be a single class in your project.

There's a couple of podcasts from a while back where the HerdingCode [0] podcast folks interview the creators of Nancy:

Also vaguely related their podcast about OWIN and Katana which Nancy can run on top of:

I really like Nancy - we've been using it for a couple years now, since MVC didn't really work with the OWIN/Katana self-hosted web-server components. I like it's style of explicitly defining your HTTP routes and handlers, versus the more implicit MVC style.

The neat thing about this is that it breaks away from the tightly-integrated IIS/ASP.NET model (which, while normally a great thing for performance reasons, can be unwanted or overkill).

Best lightweight option out there for C#, but could be better.

I wish it used composition rather than overriding everywhere, to give you more flexibility in instantiating things dynamically.

I also didn't like how it tries to encapsulate the ioc controller. Makes it difficult when you want Nancy itself to be a dependency, or to run in a repl.

I would rather allow the ioc controller to manage the web server, like Jetty does it in the Java world. Not sure anything like this exists in C# land though.

Love this framework, it has been a lifesaver when I need to implement an HTTP API in an existing Windows service, with no need to rely on IIS.

For those who already have an OpenAPI/Swagger spec, you can generate NancyFx server stub using Swagger Codegen. Please refer to https://github.com/swagger-api/swagger-codegen/wiki/Server-s... for more information.
