Description

A react-native-mqtt fork that allows Android clients to send base64 strings in byte arrays.

MQTT Features (inherited from the native MQTT framework)

• Uses MQTT Framework for IOS, Paho MQTT Client for Android
• Full Android support
• Partial iOS support
• SSL/TLS
• Native library, supports MQTT over TCP (forget websockets, we're on mobile)

Getting started

Installation

Step 1:

npm install tsm-react-native-mqtt --save

or

yarn add tsm-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 tsm-react-native-mqtt

Step 3:

iOS

Add pod 'MQTTClient' to your podfile and pod install

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

• Go to node_modules ➜ tsm-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

• Add the following line in getPackages() method inside the ReactNativeHost object in android/app/src/main/java/.../MainApplication.java:

packages.add(new RCTMqttPackage());           // as a child of the getPackages() returned array

Don't forget to include import com.tuanpm.RCTMqtt.*; with the other imports at the top.

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

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

• Insert the following lines inside the dependencies block in android/app/build.gradle:

implementation ':tsm-react-native-mqtt'

Usage

import MQTT from 'tsm-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 Set to 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

• [ ] byte array support for iOS
