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.

SQLite - The Fast and Portable Database

We concluded the previous chapter with a problem, which was that none of our data was really there. All the temperature and humidity readings we took using our sensor were rather ephemeral and disappeared as soon as we closed our browser.

Overall, there is great value in storing our data:

  • It leads to a better experience for the user because, if they refresh or close their browser, the information that they were looking at will still be there.
  • It gives us access to information that we could not obtain earlier. How does the temperature today compare to the temperature of yesterday for the same time of the day? How about last week?
  • It gives us a chance to implement new features for our application, such as filtering readings based on the time of the day or searching and sorting through the readings for a given time period.
