Service Workers: Transforming your App into a Progressive Web Application

What if we could build a web application which auto-magically works across various devices and platforms? Thanks to Progressive Web Applications (PWAs), this dream has now come true. PWAs use modern web capabilities to provide a user experience similar to that of mobile applications. PWAs make use of Web App Manifest files and Service Workers, to make the magic happen. A Service Worker is a standalone JavaScript program that can handle background/network tasks for your web application. Service Workers enable us to have total control over the outgoing and incoming network requests as well as the browser cache. I have some great news for all of you. Many browsers and modern JavaScript frameworks (React, Angular, Vue) have built-in support for Service Workers. In this talk, we will dive into exploring the transformation of a simple web application into a PWA using Service Workers.
