Implementing the application process

Since the application process is not a part of the deployed Firebase application that we built in the previous chapter, we will create a new folder for it (for this chapter, it will be named firebase-process).

First, we will be copying over the get-sensor-readings.js module from the previous implementations (shown here for reference):

    var sensor =require('node-dht-sensor')const getSensorReadings =(callback)=>{
      sensor.read(11,4,function(err, temperature,
    humidity){if(err){returncallback(err)}callback(null, temperature, humidity)})}

    module.exports = getSensorReadings

Next, we implement the core module:

    /**
     * Import the "get-sensor-readings" module, as well as
     the firebase admin module
     */const getSensorReadings =require('./get-sensor-
    readings')var admin =require('firebase-admin')/**
     * Read the JSON key that was downloaded from firebase,     in this case, it has
     * been placed in the "/home/pi" directory...
