Overview of this book

In this world of technology upgrades, IoT is currently leading with its promise to make the world a more smarter and efficient place. This book will show you how to build simple IoT solutions that will help you to understand how this technology works. We would not only explore the IoT solution stack, but we will also see how to do it with the world’s most misunderstood programming language - JavaScript. Using Raspberry Pi 3 and JavaScript (ES5/ES6) as the base to build all the projects, you will begin with learning about the fundamentals of IoT and then build a standard framework for developing all the applications covered in this book. You will then move on to build a weather station with temperature, humidity and moisture sensors and further integrate Alexa with it. Further, you will build a smart wearable for understanding the concept of fall detection. You will then extend it with the 'If This Then That' (IFTTT) rules engine to send an email on fall detection. Finally, you will be working with the Raspberry Pi 3 camera module and surveillance with a bit of facial detection using Amazon Rekognition platform. At the end of the book, you will not only be able to build standalone exciting IoT applications but also learn how you can extend your projects to another level.

Preface

Building the mobile app and implementing an end-to-end flow


In this section, we will build our mobile companion app using the Ionic framework (http://ionicframework.com/). The output or the example would be the same as what we have done for the web and desktop app.

To get started, we will install the latest version of ionic and cordova by running the following command:

npm install -g ionic cordova

Now, we need the mobile app base. If you have not already cloned the book's code repository, you can do so using the following command (anywhere on your machine):

git clone [email protected]:PacktPublishing/Practical-Internet-of-Things-with-JavaScript.git

or you can download the zip file from https://github.com/PacktPublishing/Practical-Internet-of-Things-with-JavaScript as well.

Once the repository has been downloaded, cd into the base folder and make a copy of mobile-app-base folder into chapter2 folder.

Once the copy is completed, cd into the mobile-app folder and run the following command:

npm install...
