Description

A react-native mqtt client module that works

MQTT Features (inherited from the native MQTT framework)

• 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)

Getting started

Installation

Step 1:

npm install sp-react-native-mqtt --save

or

yarn add sp-react-native-mqtt

Step 2: (Skip this step if you are using RN 0.60 or above as the module will be auto-linked)

react-native link sp-react-native-mqtt

Step 3:

iOS

Add pod 'MQTTClient' to your podfile and pod install

Alternatively you can manually link the library on iOS (click to expand)

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]

• Go to node_modules ➜ sp-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.

Android

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

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

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

Usage

import MQTT from 'sp-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);
});

API

• 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"

Todo

• [ ] Use WeakReference for timer
• [ ] Add disconnecting event
