Full Stack Web Development with Raspberry Pi 3

By: Soham Kamani

Overview of this book

Modern web technology and portable computing together have enabled huge advances in the Internet of Things (IoT) space,as well as in areas such as machine learning and big data. The Raspberry Pi is a very popular portable computer for running full stack web applications. This book will empower you to master this rapidly evolving technology to develop complex web applications and interfaces. This book starts by familiarizing you with the various components that make up the web development stack and that will integrate into your Raspberry Pi-powered web applications. It also introduces the Raspberry Pi computer and teach you how to get up and running with a brand new one. Next, this book introduces you to the different kinds of sensor you’ll use to make your applications; using these skills, you will be able to create full stack web applications and make them available to users via a web interface. Later, this book will also teach you how to build interactive web applications using JavaScript and HTML5 for the visual representation of sensor data. Finally, this book will teach you how to use a SQLite database to store and retrieve sensor data from multiple Raspberry Pi computers. By the end of this book you will be able to create complex full stack web applications on the Raspberry Pi 3 and will have improved your application’s performance and usability.

Getting Up-and-Running with Web Development on the Raspberry Pi

Creating a Web Page to Display Sensor Data

Up until now, we have been dealing primarily with data and backend code, something that is almost completely invisible to the end user of our application. We did display some data, but this was only plain text and was unintuitive for the user to see. Furthermore, we had separate URLs in order to view temperature and humidity readings. This is not the ideal experience and can be made much better.

In this chapter, we will be looking at the presentation layer, otherwise known as the UI, and use web technologies to functionally and visually enhance the user experience. First, we will look at how to extend our current application to deliver HTML to the user instead of standard plain text. We will then look at how to display temperature and humidity at the same time using different APIs. We will also look at how to add dynamic style to our...
