Build a Progressive Web App (PWA) that feels like an iOS & Android App, using Device Camera, Push Notifications, and moreAbout This VideoDetailed explanation about what a PWA exactly isHow to use an app manifest to make your web app installable on device homescreensUsing service workers to offer offline support by caching assetsAdvanced service worker usage and caching strategiesA refresher on Promises and the Fetch API as both concepts are heavily used in PWAsHow to improve user engagement by adding push notificationsA way to synchronize data in the background, even if connection is lostHow to access native device features like the camera or geolocationUsing Workbox to make service worker management easierExplanations on how to turn your next SPA project into a PWAIn DetailProgressive Web Apps (PWA) are the next big thing in web development as they bring mobile-app-like experiences to your users without requiring them to install an app from the App store/ Play store.You still create a web application (HTML, CSS, JavaScript) but this course will teach you how to add features such as camera access, service workers for offline support, push notifications, and more. This combines the best of both worlds: You deliver fast, engaging and reliable experiences whilst still having the reach and accessibility of a web page. "Progressive Web App" is simply a term that summarizes all the features that allow you to deliver mobile-like experiences. The topic is highly trending and it also is a topic which is here to stay! Not only is it strongly promoted by Google (actually a lot of talks at Google I/O 2017, Google's developer conference, were devoted to PWAs), it's also quickly being adopted by big companies like Twitter or the Washington Post. Having the skills to build and optimize these kind of web apps is already an important and highly demanded skill for modern web developers, a trend which is only going to accelerate! Therefore, learning how to build PWAs will give you a competitive edge! To ensure that you can apply the knowledge to ANY of your projects, the course project doesn't assume any JavaScript framework but focuses on the core features mentioned above!
