Eclipse Paho MQTT Go client is a Go library that enables applications to connect to MQTT brokers for publishing and subscribing to messages.

The library solves the problem of integrating MQTT messaging into Go applications by providing a fully asynchronous client implementation.

Developers should choose this library if they are building Go applications that need to communicate over MQTT in an asynchronous manner. It suits IoT and messaging scenarios where non-blocking operation is important. The library supports MQTT over WebSockets using ws:// and wss:// URI schemes, and respects standard HTTP proxy environment variables for connections behind corporate proxies. A separate MQTT V5 client is available as an alternative for applications requiring the newer protocol version. The tool integrates with Go's module system for straightforward dependency management and includes sample code in the cmd directory for reference.

Development activity shows consistent engagement with the codebase through regular commits addressing bug fixes and feature improvements. The project maintains active issue triage and responds to user-reported problems, with maintainers providing guidance on troubleshooting and directing users to relevant MQTT specification documentation when needed. Documentation is kept current with examples of error handling patterns and logging configuration to help developers debug integration issues.
