Innovations in web development are quickly replacing the need for mobile apps and the app store experience. Progressive Web Apps (PWAs) are web applications that work seamlessly for every user on every device, and they are ready to change the way we build and deploy our software. Each PWA is an application that works online or offline, on old devices and new, and that users can install just like a native app on your device. This talk will cover PWAs and the technologies that make them possible: Service Workers, Fetch API, and Web App Manifest. You'll leave this talk ready to create new PWAs and add native-like experiences to your existing apps.
