Updating the API engine

Now that we are done with the Raspberry Pi setup, we will update the API engine to accept the incoming data.

The first thing we are going to do is update api-engine/server/mqtt/index.js as follows:

var Data = require('../api/data/data.model'); 
var mqtt = require('mqtt'); 
var config = require('../config/environment'); 
var fs = require('fs'); 
var client = mqtt.connect({ 
    port: config.mqtt.port, 
    protocol: 'mqtts', 
    host: config.mqtt.host, 
    clientId: config.mqtt.clientId, 
    reconnectPeriod: 1000, 
    username: config.mqtt.clientId, 
    password: config.mqtt.clientId, 
    keepalive: 300, 
    rejectUnauthorized: false 
}); 
 
client.on('connect', function() { 
    console.log('Connected to Mosca at ' + config.mqtt.host + ' on port ' + config.mqtt.port); 
    client.subscribe('api-engine'); 
    client.subscribe('image'); 
}); 
 
client.on('message', function(topic, message) { 
    // message is Buffer 
    // console.log('Topic >> ', topic...
