Features

• No javascript, no JSX required
• typesafe client side bindings
• very simple to setup

Samples

• The source code of an sample web app can be found here

Getting Started

• Create a ASP.NET Core 2.0 Web Application (No React, No MVC, simple Web Application)

• Install this nuget package

• Extend the Startup.cs file:

      public void ConfigureServices(IServiceCollection services)
      {
          services.UseRazorReact(); // <--- Add this line
          services.AddMvc();
      }
      
      public void Configure(IApplicationBuilder app, IHostingEnvironment env)
      {
          if (env.IsDevelopment())
          {
              app.UseDeveloperExceptionPage();
              app.UseBrowserLink();
          }
          else
          {
              app.UseExceptionHandler("/Error");
          }
  
          app.UseStaticFiles();
          app.UseRazorReact(); // <--- Add this line
  
          app.UseMvc(routes =>
          {
              routes.MapRoute(
                  name: "default",
                  template: "{controller}/{action=Index}/{id?}");
          });
          
      }

• Create the react component HelloWorld.cs

       public class HelloWorld : ReactComponent<HelloWorld>
  {
      private Timer _timer;
      public string Greetings => "Hello World!";
      public DateTime ServerTime => DateTime.Now;
  
      public HelloWorld()
      {
          _timer = new Timer(state =>
          {
              Changed(nameof(ServerTime));
              PushUpdates();
          }, null, 0, 1000);
      }
      public override void Dispose() => _timer.Dispose();
  }

• Replace the content of the Index.cshtml razor file

  @page
  @addTagHelper "*, TomSun.AspNetCore.RazorReact"
  @model IndexModel
  @{
      ViewData["Title"] = "Home page";
  }
  <react-scripts/>
  
  <react component-type="@typeof(HelloWorld)">
      <div>
          Hi @HelloWorld.Bind(x => x.state.Greetings)<br />
          Server time is: @HelloWorld.Bind(x => x.state.ServerTime)
      </div>
  </react>

• Run your app. (Hint: IE11 is currently not supported, because of a bug in dotNetify/signalR)
