aspnetcore-websocket-controller

Easy WebSockets for AspNetCore 3.0.

Run dotnet add package TimoStamm.WebSockets.Controller to install.

Implement your websocket controller:

public class MyController : AWebsocketController
{
    public override async Task OnOpen(Client client)
    {
        await client.SendAsync("Hello there");
    }
    // OnTextMessage(Client client, string text)
    // OnBinaryMessage(...)
    // OnClose(...)
}

And add it in your Startup.cs

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseWebSockets();
    var myHandler = WebSocketHandler.CreateFor<MyController>(app.ApplicationServices);
    app.Run(myHandler.HandleRequest);
}

See example for a basic websocket chat. To run, cd example and dotnet run, then open http://localhost:5000/
