NancyFx - a light weight .NET framework

PM > Install-Package Nancy
PM > Install-Package Nancy.Hosting.Aspnet

We will get a successful installation message. And at the same time another new file named packages.config will be added to the project. This file contains the framework version information. Whenever we add more Nancy packages this file will be updated with those new lists.

Also, Nancy Handler's information will be updated on the web. config. Through these handlers, Nancy runs and executes the application.

So make sure to not tamper with any of these default settings. Now let's add a "Hello World" example.

Write Code

Add a class file and give a name, here the example "MainModule.cs" has the following lines of codes.

using Nancy;
using System;

namespace WebSite2 {
    public class MainModule : NancyModule {
        public MainModule() {
            Get["/"] = parameters => {
                return "<h1>Hello World!</h1><br/><br/><h3>Welcome to C# Corner!</h3><p style='color:orange'>My first Nancy example.</p>";
            };

            Get["/Sample/{yourname}"] = req => {
                return "Hello " + req.yourname;
            };
        }
    }
}

Code Explained

The "NancyModule" class is referenced from the Nancy library and inherited into "MainModule". Like Controllers in MVC, there are Modules in Nancy. A Module defines the behavior of the application. A single Module must be defined for a Nancy application, which is the starting point of an application. We can create any number of Modules inherited from NancyModule. MainModule is the constructor having two routes defined, Get["/"] and Get["/Sample/{yourname}"]. GET, POST, PUT, DELETE, HEAD, etc. are Methods supported by Nancy. A Route must follow an exact pattern's like Literal segments ("/Sample/}"), Capture segments ({yourname}), and Regular Expressions.

Run the application

It's done, now just hit F5.

Output 1

Get["/"], pointing to the root folder.

Output 2

Get[["/Sample/{yourname}"], pointing to a route path.

We can even define optional values for Capture Segments.

Get["/Sample/{yourname?suthish}"] = req =>
{
    return "Hello " + req.yourname;
};

Let's stop here, for now, I am still exploring more features and will post more content for Nancy soon.

Hope this helps you all. Post your comments.

Thank You!
