FluxFlow.Components.Mqtt.MqttNet

MQTTnet-backed adapter for FluxFlow.Components.Mqtt.

The core MQTT package stays client-library-neutral: MqttPublishNode needs only IMqttPublisher, and MqttTriggerNode needs only IMqttTriggerSource. This package supplies one concrete session object, MqttNetClient, that implements:

  • IMqttPublisher
  • IMqttTriggerSource
  • IMqttClientHealthSource

MqttNetClient owns MQTT client creation, broker connection, Last Will configuration, reconnect, publish mapping, subscription streams, manual acknowledgement, and health events.

Usage

var mqtt = new MqttNetClient(new MqttNetClientOptions
{
    Host = "localhost",
    Port = 1883,
    ClientId = "fluxflow-worker",
    LastWill = new MqttNetLastWillOptions
    {
        Topic = "workers/fluxflow/status",
        Payload = "offline"u8.ToArray(),
        Retain = true,
        QualityOfService = MqttQualityOfService.AtLeastOnce,
        ContentType = "text/plain"
    }
});

await mqtt.ConnectAsync();

var publish = new MqttPublishNode(mqtt);
var trigger = new MqttTriggerNode(mqtt, new MqttTriggerOptions
{
    TopicFilter = "commands/+",
    Mode = MqttTriggerMode.RequestReply,
    Acknowledgement = MqttTriggerAcknowledgement.OnSuccessfulResponse
});

Call ConnectAsync before using the object as a publisher or trigger source. When the MQTT client is disconnected, publish and subscribe throw MqttClientUnavailableException, which the core nodes translate into their not-connected diagnostics.

Last Will

Last Will is adapter-owned because it is registered during MQTT CONNECT. It is configured through MqttNetClientOptions.LastWill, not through publish or trigger node options. Use a normal MqttPublishRequest for graceful online/offline status messages.

Acknowledgement

For trigger subscriptions with Acknowledgement.None, MQTTnet auto-acknowledges received messages. For OnEmit and OnSuccessfulResponse, the adapter disables auto acknowledgement and exposes AckAsync/NackAsync on each received context. NackAsync maps to MQTTnet processing failure metadata and then completes the MQTT acknowledgement path; MQTT broker retry behavior depends on broker and protocol support.
