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.

What you need for this book

The reader should have some basic knowledge and programming experience (in any programming language). An awareness of the basic concepts regarding HTML and JavaScript would be a plus point, but is not required, and of will be covered in brief in this book. The reader is also expected to have a base level understanding of electronic hardware (how to connect pins and wires).

To execute all the examples given in this book, you will need the following:

  • A Raspberry Pi board, which will be the device where all the code is executed
  • Monitor, keyboard, and mouse to interact with the Raspbian OS
  • Memory card for the Raspberry Pi
  • Personal computer (optional), although this book is designed such that the entire application can be built and executed on the Pi, having a computer handy can help a lot.
