Serverless Web Applications with React and Firebase

Overview of this book

ReactJS is a wonderful framework for UI development. Firebase as a backend with React is a great choice as it is easy, powerful, and provides great developer experience. It removes a lot of boilerplate code from your app and allows you to focus on your app to get it out quickly to users. Firebase with React is also a good choice for Most Viable Product (MVP) development. This book provides more practical insights rather than just theoretical concepts and includes basic to advanced examples – from hello world to a real-time seat booking app and Helpdesk application This book will cover the essentials of Firebase and React.js and will take you on a fast-paced journey through building real-time applications with Firebase features such as Cloud Storage, Cloud Function, Hosting and the Realtime Database. We will learn how to secure our application by using Firebase authentication and database security rules. We will leverage the power of Redux to organize data in the front-end, since Redux attempts to make state mutations predictable by imposing certain restrictions on how and when updates can happen. Towards the end of the book you will have improved your React skills by realizing the potential of Firebase to create real-time serverless web applications.

Best practices with Firebase


In Firebase, we all know that data is stored in JSON tree format, which is synchronized in realtime to every connected device. So while building cross-platform applications (web, iOS, and Android) with Firebase, we can share one instance to all your apps to receive the latest updates with new data from Realtime Database. So when we add the data into the JSON tree, it becomes the node in the existing JSON Structure with an associated key, so we always need to plan how data will be saved to build a properly structured database.

Writing the data

In Firebase, we have four methods available to write a data into the Firebase database:

set( )

Write or replace data to a defined path, like messages/tickets/<uid>.

update( )

Update to specific children of node without replacing the other child nodes. We can also use the update method to update the data into multiple locations.

push( )

To add a list of data in the database, we can use the push() method; it generates a unique...
