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.

Securing our application

In the previous chapter, we were able to read from our Firebase Database to get our readings shown on the frontend. Now, the database has to be written to. Exposing our write functionality to the outside world the way we did for reading the data would have disastrous consequences, since we would essentially grant permission to everyone to modify our data at any time.

In order to make sure our data is modified only by us, we need to make secure modification requests. Before we get to the implementation, let's first create our credentials on Firebase; we will need these later when we have to access the database to update data.

In the Firebase console, go to the SERVICE ACCOUNTS section of your application settings, which can be found by clicking on the settings icon in the top right:

Under the Firebase Admin SDK tab, you can generate a new key for...
