ReQueue

C# Library to use a redis streams for asynchronous messaging. Perfect for small projects you don't want to set up RabbitMQ for. Try using it with a fast redis implemetation like Dragonfly.

Example

Producer

internal class Program
    {
        static async Task Main(string[] args)
        {
            var manager = new ConnectionHub("localhost:6379", 0);
            var queue = manager.GetMessageQueue("numQueue");

            int i = 0;
            while (true)
            {
                var id = await queue.PublishAsync(new Dictionary<string, string>()
                {
                    { "orderId", Guid.NewGuid().ToString() },
                    { "status", "created" },
                    { "amount", i.ToString() }
                });
                Console.WriteLine(id);
                i += 1;
            }
            Console.ReadLine();
        }
    }

Consumer

internal class Program
    {
        static async Task Main(string[] args)
        {
            var manager = new ConnectionHub("localhost:6379", 0);
            var consumer = manager.GetMessageConsumer("numQueue", "order-group", "order-processor-1");

            consumer.OnMessageReceived += ConsumerOnOnMessageReceived;
            consumer.StartConsuming();
            
            Console.ReadLine();
            consumer.StopConsuming();
        }

        private static async Task ConsumerOnOnMessageReceived(ReQueueMessage message)
        {
            Console.WriteLine($"Received message: {message.Id}");
            foreach (var kv in message.Values)
                Console.WriteLine($" - {kv.Key}: {kv.Value}");

            await Task.CompletedTask;
        }
    }

Features

• Non-blocking asynchronous processing
• Delegate-based event handling (OnMessageReceived)
• Simple start/stop consumer API
• Generic message payload support
• Efficient resource usage
