#Import

typescript 
1import { MqttJsClientProvider } from "@alepha/mqtt";

#Overview

MQTT client provider backed by the mqtt npm package (mqtt.js).

Selected by AlephaMqtt when MQTT_URL is set on Node or Bun. MQTT 5 by default; protocolVersion: 4 in the options atom speaks MQTT 3.1.1.

Resubscription after a reconnect is done here rather than by mqtt.js, so every subscription keeps its Subscription Identifier and connect() can wait for the SUBACKs before it resolves.
