Description

react-native mqtt client module

MQTT Features (inherit from native MQTT framework)

• Use MQTT Framework for IOS, Paho MQTT Client for Android
• Support both IOS and Android
• SSL/TLS
• Native library, support mqtt over tcp

Warning

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

Getting started

iOS

• 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 and libicucore.tbd 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)

Android

• Modify the following in android/app/main/java/.../MainApplication.java to include:

// Add this to the imports in the top of your file:
import com.tuanpm.RCTMqtt.*;


// Add this where the getPackages() list:
new RCTMqttPackage()

• 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:

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

Usage

var mqtt    = require('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);
});

  • 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

  • disconnect: disconnect
  • subscribe(topic, qos)
  • publish(topic, payload, qos, retain)
