#Installation

#Overview

MQTT 5 client for Alepha.

A lifecycle-managed client with byte payloads, Last Will (settable by code), reconnection and dispatch by Subscription Identifier.

• MQTT_URL set (Node or Bun): MqttJsClientProvider, on mqtt.js.
• Otherwise: MemoryMqttClientProvider, on an in-process broker.

An app's own MqttClientProvider substitution wins over both.
