17:30 Workbox v4: a brand new workbox-window module
by Maxim Salnikov, Azure Dev Tech Lead, Microsoft

The next major version of the very popular PWA helper library was just released. Workbox 4 brings many interesting additions to the existing modules and only a few minor breaking changes. Also, it ships one totally new module called workbox-window, to fulfill the need of developers in a simple and powerful way to register the service worker, to hook into its lifecycle, and to provide a bi-directional communication channel with the app. This is the first module of Workbox to be used in the window context, i.e. in our application’s (not service worker’s) code.

Let’s explore this new module to check what will it take to build the well-known “refresh-to-update-version” technique — one of the UX best practice for PWA.

18:10 Why you should consider Web Assembly in your next frontend project
by Håkan Silfvernagel, Senior Consultant at Miles

During the last decades a growing trend has been to put more and more functionality into the client by using the latest and greatest JavaScript framework. But what if we could be using native code in the browser in order to run computations faster and potentially reuse code from the backend in the frontend.

Enter Web Assembly. Web assembly is a new web standard which enables you to run native code as part of your current JavaScript framework. Thistalk will give you a thorough understanding of what web
assembly is and how you can use it in your project.

We will cover a practical example writing our web assembly using Rust. We will go through everything from writing your web assembly code to publish it as a npm package and finally use it in an existing web application.
