SignalrMQ

The Idea

Message Brokers like MQTT oder RabbitMQ are very great and awesome tools, but maybe sometimes is it a little too much overhead to setup a dedicated instance of such type of software.

Also if you are going ahead with the .net core environment maybe you wish to implemement a MQTT-like broker instance for your own or in your own application. So, here is the try to implement such a piece of software using SignalR.

Features

• Publish-Subscribe principle similar to MQTT
• Reqest messages (Messages with return value, personal wishlist-feature)

Implementation

This project consist of:

• a broker library which implements the SignalR-Hub
• a client library

The implementation based on .Net 6 Core

Usage

Broker

Implement in exisiting or new (Asp.Net/Blazor/WorkerService)-Application!

Nuget

Use Nuget-Package

Install-Package SignalrMQ.Broker

Add in Startup.cs/Program.cs:

app.UseEndpoints(endpoints => endpoints.MapHub<SignalrMqBroker>("signalrmqbrokerhub"));

Sample-Project: SignalrMQ.BlazorBroker

Clients

Nuget

Use Nuget-Package

Install-Package SignalrMQ.Client

services.AddSignalrMqClientService(opts => hostContext.Configuration.GetSection(nameof(SignalrMqEndpoint)).Bind(opts));

Configure in aasettings.json:

"SignalrMqEndpoint": {
    "Host": "localhost",
    "Port": 7284,
    "Autoconnect": true
  }

Subscribe, Publish, Request ... more description coming soon. Please take a look at Worker.cs

Missing features

Currently is no authentification implemented. Please be aware of this if you publish SignalrMQ-based Applications in public internet.
