Mows - MQTT.js over WebSockets

npm install mows --save

This project is deprecated, as it merged with MQTT.js since version 1.0.0

Tunnel MQTT through HTML5 websockets using node.js Streams, thanks to websocket-stream.

Mows is based on MQTT.js and it offers the same high-level API.

in the Browser

you can use browserify to package this module for browser use.

var mows   = require('mows')
  , client = mows.createClient();
  // pass an optional 'ws://localhost:port' here.

client.subscribe('presence');
client.publish('presence', 'Hello mqtt');

client.on('message', function (topic, message) {
  console.log(message);

  client.end();
});

See MQTT.js for the full API.

browserify steps

npm install -g browserify // install browserify
cd node_modules/mows
npm install . // install dev dependencies
browserify . -s mows > mows.js // require mows.js in your client-side app

On Node

var mows   = require('mows')
  , client = mows.createClient('ws://localhost:12345');

client.subscribe('presence');
client.publish('presence', 'Hello mqtt');

client.on('message', function (topic, message) {
  console.log(message);

  client.end();
});

See MQTT.js for the full API.

Server API

It uses the ws module to bake an MQTT-enhaced websocket server:

var mows = require('mows');

var server = mows.createServer(function(client) {
  // just as MQTT.js
});

server.listen(3000);

or it can be just used to attach it to an existent http server:


var http = require('http')
  , mows = require('mows')
  , server = http.createServer();

mows.attachServer(server, function(client) {
  // just as MQTT.js
});

server.listen(3000);
