Full Stack Web Development with Raspberry Pi 3

By: 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.

Integrating SQLite into Our Application

In the previous chapter, we took a look at SQLite and the functionality it can provide us in order to persist our data. We ended up learning a lot about SQLite but did not make any change to our existing application. In this chapter, we are going to get back down to our application core and enhance it to support data persistence with SQLite!

Integrating SQLite into our application requires some consideration to the following topics:

  • How to interface our running SQLite instance with node.
  • When to update the database with our data.
  • When to read from the database. We will make use of our existing caching module to make this more efficient.

We also discussed the numerous possibilities that adding persistence was going to enable. We can't just let that go to waste. In this chapter, we will also be adding new features, such as the following...
