mqtt-shepherd is a network server and manager for the lightweight MQTT machine network (LWMQN)
Lightweight MQTT machine network (LWMQN) is an open source project that follows part of OMA LWM2M v1.0 specification to meet the minimum requirements of machine network management.
- LWMQN project provides you with this machine-side mqtt-node library and a server-side mqtt-shepherd library to build your machine network with JavaScript and node.js easily.
- Server-side library: mqtt-shepherd (this module)
- Client-side library: mqtt-node
- A simple demo webapp
- Communication based on MQTT protocol and aedes broker.
- Embedded persistence (NeDB) and auto-reloads Client Devices at boot-up.
- Build your IoT network with or without cloud services.
- LWM2M-like interfaces for Client/Server interaction.
- Hierarchical Smart Object data model (IPSO), which leads to a comprehensive and consistent way in describing real-world gadgets.
- Easy to query resources on a Client Device with the URI-style path, and everything has been well-organized to ease the pain for you to create RPC interfaces for your webapps, such as RESTful and websocket-based APIs.
- LWMQN Server is your local machine gateway and application runner. But if you like to let your machines go up cloud, why not? It's node.js!
- Server: LWMQN server
- Client or Client Device: LWMQN client (machine)
- MqttShepherd: Class exposed by
require('mqtt-shepherd') - MqttNode: Class to create a software endpoint(proxy) of a remote Client Device on the server
- qserver: Instance of MqttShepherd Class
- qnode: Instance of MqttNode Class
Currently Node.js 8.x LTS or higher is required.
$ npm install mqtt-shepherdvar MqttShepherd = require('mqtt-shepherd');
var qserver = new MqttShepherd(); // create a LWMQN server
qserver.on('ready', function () {
console.log('Server is ready.');
// when server is ready, allow devices to join the network within 180 secs
qserver.permitJoin(180);
});
qserver.start(function (err) { // start the sever
if (err)
console.log(err);
});
// That's all to start a LWMQN server.
// Now qserver is going to automatically tackle most of the network managing things.Licensed under MIT.
