GenHTTP.Modules.Pages

The pages module allows the server to generate HTML pages (e.g. error messages or the directory listing) and can be used to render custom pages from a template, using Cottle as a rendering engine. Support for rendering websites in GenHTTP is minimalistic, so you should not use this for a website project.

Page Rendering

The following example will show you how to use a Cottle template file to generate a web page with dynamic content via GenHTTP.

using Cottle;

using GenHTTP.Api.Protocol;

using GenHTTP.Engine.Kestrel;

using GenHTTP.Modules.Functional;
using GenHTTP.Modules.IO;
using GenHTTP.Modules.Pages;
using GenHTTP.Modules.Practices;

var template = Renderer.From(Resource.FromAssembly("Template.html").Build());

var app = Inline.Create()
                .Get(async (IRequest request) =>
                {
                    var data = new Dictionary<Value, Value>
                    {
                        ["users"] = Value.FromEnumerable(GetUsers())
                    };

                    return request.GetPage(await template.RenderAsync(data));
                });

await Host.Create()
          .Handler(app)
          .Defaults()
          .Development()
          .Console()
          .RunAsync();

static List<Value> GetUsers()
{
    var result = new List<Value>();

    result.Add(Value.FromDictionary(new Dictionary<Value, Value>()
    {
        ["id"] = 1,
        ["name"] = "Some User"
    }));

    return result;
}
