Developing the Node.js Thing app

Now, we will set up the app and write the required code:

1. From the Terminal, once you are inside the AWS-IoT-Thing folder, run the following command:

$ npm init -y

2. Next, we will install aws-iot-device-sdk (http://npmjs.com/package/aws-iot-device-sdk) from NPM. This module has the required client code to interface with AWS IoT. Execute the following command:

$ npm install aws-iot-device-sdk --save  

3. Next, we will install rpi-dht-sensor (https://www.npmjs.com/package/rpi-dht-sensor) from NPM. This module will help in reading the DHT11 temperature and humidity values. Let's run the following command:

$ npm install rpi-dht-sensor --save  

4. Your final package.json file should look like this:

{ "name": "AWS-IoT-Thing", ...
