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.

Summary


This chapter explained how we can configure and initialize the Firebase Admin SDK to create our app backend in NodeJS. It also explained how we can manage our app users using User Management API of Firebase Admin without going to Firebase Console, such as the following:

  • Create
  • Delete
  • Update
  • Remove

Firebase Admin SDK gives us the power to create and verify the Custom JWT tokens, which allow the user to authenticate with any provider, even if it's not available in the Firebase Auth Providers list. It also gives you the power to manage the user's session in case of any change in user information, such as the user is deleted, disabled, the email address or password is changed, and more.

We also learned how we can control the access to custom claims. This helps us provide the ability to implement role-based access control to give users different levels of access (roles), in Firebase apps.

In the next chapter, we will learn the database security risks and the checklist to prevent such threats...
