WebVR enables web developers to create frictionless, immersive experiences. Reach all VR headsets and the billions of users without VR hardware at once with a single web app. We’ll explore how to get started with WebVR by creating an app on stage, and show you how others are already using WebVR today.

We’ll look at how apps built using React, Preact, Vue, Angular & Polymer can be used to build instantly interactive, engaging & data-plan sensitive user experiences. We'll also look at how this investment paid off on core business metrics. You’ll leave this session learning PWA best practices, patterns for efficiently loading websites and the latest tools for getting fast and staying fast.

Performance is crucial for user engagement, especially on mobile web. Yet users are regularly bogged down by slow page loads, delayed interactivity after page load, high input latency on critical interactions (tap, click, scroll etc), and janky animations or scrolling. These negative experiences turn away users and hurt businesses. Developers need to measure performance in the real world to get insight into their users’ experiences on the myriad configurations of devices and networks. Unfortunately, many of the techniques used today don’t capture the right metrics or make performance worse. This talk will cover the new metrics and platform APIs that enable user-centric performance measurement, both in the lab and the real world. We’ll show how developers can track down problems, understand their root causes, and prevent future regressions to ensure users consistently get a great experience.

WebAssembly is a fast, portable, compact, cross-browser binary format for compilation to the Web. It allows new types of applications and heavy 3D games to run efficiently in browsers. We'll describe what web assembly is, the problems it solves, the low level format and compilation tools available to try it out. In addition, the interfacing between compiled language modules and Javascript is explained. Video: https://www.youtube.com/watch?v=6v4E6oksar0

On mobile, a seamless user experience can be the difference between success or failure for a product. In this talk, Mustafa and Owen will share the secrets to creating UX on the web that “just feels right” in the way users have come to expect. You'll see some real world examples of how this is done right, as well as get UX Principles that cover slick transitions, handling network failures, increasing conversions and much more.

In this video, you'll learn where to start with Progressive Web Apps, what to implement, and how to prioritize PWA techniques. You'll also learn how to make the most of 'low hanging fruit' and take advantage of small changes that can have a big impact. Video at: https://www.youtube.com/watch?v=KRSTpo6gqqU

Progressive Web Apps combine the best of the web and the best of apps. They load quickly, even on flaky networks, can re-engage with users by sending web push notifications, have an icon on the home screen, and load as top-level, full screen experiences. In this video, Sam Dutton explains the what, why, and how of Progressive Web Apps, and works through code examples. Video at: https://www.youtube.com/watch?v=eodArdGRIVQ

Whether you work on e-commerce, media, gaming, or some other type of site, you need to know about the future of the web. In this video, you'll learn what's next for APIs, platforms, and technologies. Chances are that you don't need a native app after all… Video at: https://www.youtube.com/watch?v=qnI2S_9TN-8

For most of the web, poor network connectivity destroys the user experience. We can do better. In this session we'll take an online-only site and turn it into a fully network-resilient, offline-first installable progressive web app, and this won't involve rebuilding from scratch; it'll be done in small iterations, with each step improving the user experience whether they're offline, online, or anything in between. This session will cover ServiceWorker, web manifests, add-to-homescreen banners, IndexedDB and BackgroundSync APIs. Video at: https://www.youtube.com/watch?v=cmGr0RszHc8
