ReQueue

C# Library to use a redis list 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

Object

The library uses MessagePack under the hood, so make sure your object is marked as MessagePack serilizable.

[MessagePackObject(keyAsPropertyName: true)]
public class Data
{
    public int Foo { get; set; }
}

Producer

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

        for (int i = 0; i < 100; i++)
        {
            var item = new Data { Foo = i };
            await queue.EnqueueMessages(item);
            Console.WriteLine($"Sending -> {i}");
        }

        Console.ReadLine();
    }
}

Consumer

internal class Program
{
    static async Task Main(string[] args)
    {
        var manager = new ConnectionHub("localhost", 0);
        var queue = manager.GetMessageQueue<Data>("numQueue");
        var tokenSource = new CancellationTokenSource();
        tokenSource.CancelAfter(TimeSpan.FromDays(6));

        await queue.DequeueMessages(x => {
            Console.WriteLine($"Recieved -> {x.Foo}");
        }, tokenSource.Token);
        Console.ReadLine();
    }
}

Filter Example

Filters out messages that don't meet set criteria. By default, messages that are filtered out will be readded to the end of the queue.

queue.DequeueMessages(x => {
    Console.WriteLine($"Recieved -> {x.Foo}");
}, tokenSource.Token, data => {
    if (data.Foo % 2 == 0){
        return true;
    }
    
    return false;
});
