Progressive Web Apps with React

By: Scott Domes

Overview of this book

For years, the speed and power of web apps has lagged behind native applications. Progressive Web Apps (PWAs) aim to solve this by bridging the gap between the web apps and native apps, delivering a host of exciting features. Simultaneously, React is fast becoming the go-to solution for building modern web UIs, combining ease of development with performance and capability. Using React alongside PWA technology will make it easy for you to build a fast, beautiful, and functional web app. After an introduction and brief overview of the goals of PWAs, the book moves on to setting up the application structure. From there, it covers the Webpack build process and the process of creating React components. You'll learn how to set up the backend database and authentication solution to communicate with Firebase and how to work with React Router. Next, you will create and configure your web app manifest, making your PWA installable on mobile devices. Then you'll get introduced to service workers and see how they work as we configure the app to send push notifications using Firebase Cloud Messaging. We'll also explore the App Shell pattern, a key concept in PWAs and look at its advantages regarding efficient performance. Finally, you'll learn how to add of?ine capabilities to the app with caching and confirm your progress by auditing your PWA with Lighthouse. Also, you'll discover helper libraries and shortcuts that will help you save time and understand the future of PWA development.

Chapter 4. Easy Backend Setup With Firebase

Our application looks pretty, but it doesn't do that much. We have a login form that doesn't let users actually log in.

In this chapter, we'll get started on the backend of our application. In our case, that means setting up a database to save users and their messages. In one chapter, we will cover everything we need to let our users create accounts and log in. We'll also dive deeper into React and component state. We'll learn the following things:

  • What Firebase is
  • Gotchas and problems to look out for
  • How to deploy our application
  • User authentication (signup and login)
  • React life cycle methods

Let's get to it!
