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.

Extending our application

The first step in enhancing our application is to have it deliver HTML instead of plain text.
HTML is the markup language of the web, which is used to give a web page its structure. In essence, it's just a bunch of tags that give meaning to the text.

For example, the current output from the temperature API is 26°C. Although it gives us the information we need, it would be more meaningful to highlight the actual value more than the unit. An output of 26°C looks better than our plain text version.

Let's translate this into HTML. We have the strong tag, which is used to give emphasis to the text by making it thicker than usual.

The standard format of HTML tags is as follows:

    <tag>text</tag>

Here, we replace tag with the name of our tag. If we wanted to make only the value bolder, we would write this:

    <strong&gt...
