• Native library, support mqtt over tcp

This library in progress developing, api may change, SSL/TLS non verify

npm install rusfearuth/react-native-mqtt --save

or

yarn add rusfearuth/react-native-mqtt

• In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
• Go to node_modules ➜ react-native-mqtt and add RCTMqtt.xcodeproj
• In XCode, in the project navigator, select your project. Add libRCTmqtt.a to your project's Build Phases ➜ Link Binary With Libraries
• Click RCTMqtt.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). In the Search Paths section, look for Header Search Paths and make sure it contains both $(SRCROOT)/../../react-native/React - mark as recursive.
• Run your project (Cmd+R)

• Modify the ReactInstanceManager.builder() calls chain in android/app/main/java/.../MainActivity.java to include:

import com.tuanpm.RCTMqtt.*; // import


.addPackage(new RCTMqttPackage()) //for older version

new RCTMqttPackage()           // for newest version of react-native

• Append the following lines to android/settings.gradle before include ':app':

include ':react-native-mqtt'
project(':react-native-mqtt').projectDir = new File(rootProject.projectDir,  '../node_modules/react-native-mqtt/android')

• Insert the following lines inside the dependencies block in android/app/build.gradle, don't missing apply plugin:'java' on top:

compile project(':react-native-mqtt')

Notes:

dependencies {
  compile project(':react-native-mqtt')
}

import MQTT from 'react-native-mqtt';

/* create mqtt client */
MQTT.createClient({
  uri: 'mqtt://test.mosquitto.org:1883',
  clientId: 'your_client_id'
}).then(function(client) {

  client.on('closed', function() {
    console.log('mqtt.event.closed');
  });

  client.on('error', function(msg) {
    console.log('mqtt.event.error', msg);
  });

  client.on('message', function(msg) {
    console.log('mqtt.event.message', msg);
  });

  client.on('connect', function() {
    console.log('connected');
    client.subscribe('/data', 0);
    client.publish('/data', "test", 0, false);
  });

  client.connect();
}).catch(function(err){
  console.log(err);
});

• mqtt.createClient(options) create new client instance with options, async operation

  • uri: protocol://host:port, protocol is [mqtt | mqtts]
  • host: ipaddress or host name (override by uri if set)
  • port: port number (override by uri if set)
  • tls: true/false (override by uri if set to mqtts or wss)
  • user: string username
  • pass: string password
  • auth: true/false - override = true if user or pass exist
  • clientId: string client id
  • keepalive

• client

  • on(event, callback): add event listener for
    • event: connect - client connected
    • event: closed - client disconnected
    • event: error - error
    • event: message - message object
  • connect: begin connection
  • disconnect: disconnect
  • subscribe(topic, qos)
  • publish(topic, payload, qos, retain)

• message

  • retain: boolean false
  • qos: number 2
  • data: string "test message"
  • topic: string "/data"

• Use WeakReference for timer
• Add disconnecting event
