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.

  The new MVC (or just Core now) is great, and much lighter / higher performance. However, it's still more like Rails than Sinatra (to use a Ruby analogy), which I guess is the niche Nancy is trying to fill.

    Nancy Sinatra is the daughter of Frank Sinatra, hence "Nancy".

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-getting-nancy-running-on-coreclr 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 https://anclafs.com/#web (edit: done)

  Npgsql supports .ner core, as does Marten
  - jsingleton 10y ago
    OK, I'll update Npgsql. Not sure what you mean by Marten.

      Marten is a .NET database client that uses PostgreSQL as a document-database: http://jasperfx.github.io/marten/documentation/documents/ http://jasperfx.github.io/marten/documentation/documents/

        Cool, Raven was a pain last time I used it. I'll try this next time I need something like that. FYI this is now in https://anclafs.com/#orms--dbs https://anclafs.com/#orms--dbs thanks to https://github.com/phillip-haydon https://github.com/phillip-haydon.

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.

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.

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.

  Yes, the web server should be just another interface that the domain uses to communicate.

If you like this sort of thing, and enjoy or are curious about F-Sharp, give Suave a look: https://suave.io/ https://suave.io/ There are two great tutorials for it: https://www.gitbook.com/book/theimowski/suave-music-store/details https://www.gitbook.com/book/theimowski/suave-music-store/de... and http://products.tamizhvendan.in/fsharp-applied/ http://products.tamizhvendan.in/fsharp-applied/ which gets more into how suave actually works.

There's a couple of podcasts from a while back where the HerdingCode [0] podcast folks interview the creators of Nancy: http://herdingcode.com/herding-code-123-andreas-hakansson-and-steven-robbins-on-nancyfx/ http://herdingcode.com/herding-code-123-andreas-hakansson-an... http://herdingcode.com/herding-code-156-catching-up-with-andreas-hakansson-and-steven-robbins-on-nancyfx/ http://herdingcode.com/herding-code-156-catching-up-with-and... Also vaguely related their podcast about OWIN and Katana which Nancy can run on top of: http://herdingcode.com/herding-code-164-owin-and-katana-with-louis-dejardin/ http://herdingcode.com/herding-code-164-owin-and-katana-with...

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).
- tracker1 10y ago
  IIRC, ASP.Net <strike>5</strike> Core allows for stand-alone deployments, and uses the same libuv under the covers than Node does. The development on the open Core version of the .Net platform has been interesting to watch, and has me actually interested in looking into it again.

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-stub-generator-HOWTO#nancyfx-module https://github.com/swagger-api/swagger-codegen/wiki/Server-s... for more information.
