A react-native mqtt client module that works

• Uses MQTT Framework for IOS, Paho MQTT Client for Android
• Supports both IOS and Android
• SSL/TLS
• Native library, support mqtt over tcp (forget websockets, we're on mobile)

npm install react-native-mqtt-angelos3lex --save

or

yarn add react-native-mqtt-angelos3lex

react-native link react-native-mqtt-angelos3lex

Add pod 'MQTTClient' to your podfile and pod install

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

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

new RCTMqttPackage()           // as a child of the getPackages() returned array

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

include ':react-native-mqtt-angelos3lex'
project(':react-native-mqtt-angelos3lex').projectDir = new File(rootProject.projectDir,  '../node_modules/react-native-mqtt-angelos3lex/android')

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

compile project(':react-native-mqtt-angelos3lex')

import MQTT from 'react-native-mqtt-angelos3lex';

/* 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
