Node.js MQTT server is a server that uses the MQTT protocol to receive and send messages between MQTT clients. MQTT stands for Message Queuing Telemetry Transport, a lightweight messaging protocol that is widely used in the Internet of Things (IoT) and other applications that require real-time communication. Some popular Node.js MQTT servers include: 1. Mosca: A powerful MQTT broker for Node.js that supports QoS levels 0, 1, and 2, as well as message persistence and clustering. 2. Aedes: A lightweight and fast MQTT broker written in Node.js, optimized for low memory usage and high throughput. 3. MQTT.js: A client library for MQTT written in JavaScript. While not a server, it can be used to build custom MQTT clients and servers. 4. HiveMQ: A commercial MQTT broker that provides enterprise-grade features such as clustering, security, and high availability. When choosing a Node.js MQTT server, it's important to consider factors such as performance, scalability, security, and ease of use.
