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 1. Creating Our App Structure

Welcome to Progressive Web Apps with React!

This book will take you through the entire process of building a React application that also functions as a Progressive Web App. We'll cover not only the "how" of constructing such an application, but also highlight best practices and how to measure your application to ensure successful implementation of PWA features.

Progressive Web Apps are poised to become the future of web applications. They promise a bevy of additional functionality, such as push notifications and the ability to be installed, which pushes them into the realm of native iOS or Android apps. Additionally, a strong focus on performance (taking advantage of cutting-edge web technology) means that PWAs create apps that are fast for everyone.

We'll cover each facet of PWAs in depth, as well as the process of converting a regular web application into a progressive one. We'll also dive deep into React best practices, using libraries such as React Router.

In this chapter, we will get started with the basic structure of our application. Here's what we'll cover:

  • The use cases of Progressive Web Apps
  • The basic user stories we want our app to fulfill
  • The project structure and basic HTML
  • Installing dependencies
  • Getting started with React

First, let's set the scene for our application's journey.
