A Ballerina library for building MQTT clients and listeners to interact with MQTT servers.
Ballerina MQTT is a library that provides an implementation to interact with MQTT servers via MQTT client and listener components. It enables developers to build publish-subscribe messaging applications using the lightweight MQTT protocol within the Ballerina programming language. The library solves the problem of integrating MQTT-based communication into Ballerina services for IoT and machine-to-machine scenarios.
Ballerina developers building IoT applications, messaging systems, or services that require MQTT-based publish-subscribe communication.
Developers choose this library for its native Ballerina integration, type-safe API, and seamless support for both MQTT publishers and subscribers without needing external dependencies. It leverages Ballerina's concurrency model for efficient message handling.

Designed to leverage Ballerina's concurrency and network-aware type system, providing a seamless and type-safe API for MQTT operations, as stated in the philosophy.
Supports both manual and automatic acknowledgements via the 'manualAcks' configuration, allowing developers to control message processing flow, demonstrated in the listener code snippet.
Implements the MQTT protocol optimized for low-bandwidth, high-latency networks, making it ideal for IoT and machine-to-machine communication, per the key features.
Integrates subscribers with 'mqtt:Service' for handling messages and errors, enabling clean separation of concerns and easy error management, as shown in the example service code.
Tightly coupled to the Ballerina language and platform, limiting its use in polyglot environments and making it less suitable for teams not already invested in Ballerina.
The README focuses on basic functionality; advanced MQTT features such as QoS levels, session persistence, or MQTT 5.0 support are not explicitly documented, which could hinder complex use cases.
Requires manual management of client IDs and connection configurations, which, while flexible, might add overhead for simple deployments compared to more abstracted libraries.
