Web Socket Hub middleware for .NET

dotnet-websocket

WebSocketHub is a middleware for ASP.NET Core that simplifies the process of building WebSocket applications. It provides a flexible and easy-to-use API for handling WebSocket connections and messages, and allows you to easily integrate WebSocket functionality into your existing ASP.NET Core application. With WebSocketHub, you can quickly build real-time applications that can handle large volumes of data and provide a seamless user experience. Whether you're building a chat application, a real-time dashboard, or any other type of WebSocket-based application, WebSocketHub makes it easy to get started and build robust, scalable solutions.

Getting Started

1. Add the following code to register the WebSocketHub service with the desired key type. Replace TKey with the type of key you want to use for WebSocket connections.

services.AddWebSocketHub<TKey>();

2. (Optional) Configure the WebSocketHub by chaining method calls to the AddWebSocketHub method:

services.AddWebSocketHub<TKey>()
  .AddJsonSerializerSettings(jsonSerializerSettings)
  .AddReceiveBufferSize(receiveBufferSize)
  .AddRequestHandler<THandler>(messageType);

3. Add the following code to use the WebSocketHub middleware:

 app.UseWebSocketHub(
     acceptIf: (httpContext) => /* Your accept condition */,
     keyGenerator: (httpContext) => /* Your key generator */
 );

4. Use the WebSocketHub instance with dependency injection wherever you need it.

 private readonly WebSocketHub<TKey> _webSocketHub;

 public MyController(WebSocketHub<TKey> webSocketHub)
 {
     _webSocketHub = webSocketHub;
 }

 [HttpGet("GetSocketList")]
 public IActionResult GetSocketList(TKey id)
 {
     var socketListOfUser = _webSocketHub.GetSocketList(id);
     return Ok(socketListOfUser);
 }

5. Handle requests with classes that implement the IWebSocketRequestHandler interface. Don't forget to register the implementation of IWebSocketRequestHandler with the WebSocketHub

 public class MyWebSocketRequestHandler : IWebSocketRequestHandler
 {
     public Task HandleRequestAsync(string key, string data)
     {
         // Handle the WebSocket request
         return Task.CompletedTask;
     }
 }

 services.AddWebSocketHub<TKey>()
     .AddRequestHandler<MyWebSocketRequestHandler>("messageType");
