Key FeaturesBring the best of mobile sites and native apps to your users with progressive web applicationsCreate fast, reliable, and engaging PWAs with React and FirebaseCreate high-performance applications even with low connection speeds by leveraging modern web technologiesBook DescriptionFor 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. Youll 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 youll get introduced to service workers and see how they work as we configure the app to send push notifications using Firebase Cloud Messaging. Well also explore the App Shell pattern, a key concept in PWAs and look at its advantages regarding efficient performance. Finally, youll learn how to add offline capabilities to the app with caching and confirm your progress by auditing your PWA with Lighthouse. Also, youll discover helper libraries and shortcuts that will help you save time and understand the future of PWA development.What you will learnSet up Webpack configuration, as well as get the development server runningLearn basic Firebase configuration and deploymentCreate routes, manage multiple components, and learn how to use React Router v4 to manage the flow of dataUse React life cycle methods to load dataAdd a service worker to the app and learn how it worksUse a service worker to send Push NotificationsConfigure Webpack to split up the JavaScript bundle and lazy load component filesLearn how to use the web Cache API to use your app offlineAudit PWAs with Googles Lighthouse toolAbout the AuthorScott Domes is a full stack developer who specializes in React, with a passion for building powerful and performant web applications, and for playing with shiny new technologies.
