Vue 3 will feature improved performance, better TypeScript support, improved Composition API, and Fragment Support. Additionally, it will have a new version of the Vue CLI and a new compiler architecture for improved build times.

Stop Writing Your Routes
The more you keep working on an application, the more complicated its routing becomes, and the easier it is to make a mistake. ""Was the route named users or was it user?"", ""Did it have an id param or was it userId?"". If only TypeScript could tell you what are the possible names and params. If only you didn't have to write a single route anymore and let a plugin do it for you. In this talk we will go through what it took to bring automatically typed routes for Vue Router.

Let’s Get Visual - Visual Testing in Your Vue.JS Project
Visual testing compares the appearance of your application with a previous state. If changes become visible, you can allow them or not. So you or your testers have their eyes everywhere - without needing to check manually repeatedly. I've been using visual testing for a while, saving my neck a few times. Let's look at my journey together and explore if and how visual testing can also help your projects.

Alive and Kicking - A Vue Into Rock & Roll
Rock & roll is alive and kicking and in this talk I will showcase that Vue is so versatile it can be used to do audio visualisations while rock guitar soars through the browser. The audience will have access to a vue application which allows them to vote for a song to be played live on stage. The screen shows all the votes and I play them as they come up. While playing music meta data is shown and an audio visualisation plays while I’m rocking on stage. The more votes a song gets, the higher it shows on the list and the more chance I’ll play it. The whole experience is created using Vue and Uniform. Next to waking the audience up with some spicy rock & roll, I will explain how the software was build and why Vue is such an important technology for composable architectures with multiple channels. Vue is also used to control the guitar sound, right from the browser.

Building Backwards Compatible Vue Libraries
Many organizations with component libraries are working on upgrades for their Vue 2 apps so that they can support Vue 3. Sometimes it's not easy! Ideally, you could write your code once and cross-compile it for different Vue runtimes. In this talk, we'll do exactly that. At the end, you'll have a recipe for shipping libraries that support both Vue 2 and Vue 3.

Writing Good Tests for Vue Applications (e2e vs. Component Tests, Features of a *Good* Test)
The emergence of SPAs, and therefore logic-heavy client-side code, drastically changed the game for front-end developers. As a result, for the last couple of years, we have had to catch up with sophisticated techniques to build high-quality applications—one of the essential being testing.More and more people started to add tests to their Vue.js-powered applications. With varying degrees of success. The field is still relatively new, and we all need more experience in how to test client-side applications most effectively.With my talk, I want to walk through 1) how to come up with a solid testing strategy (tools and practices) and 2) work on a real-world example of how we combine E2E testing with component testing.I want to highlight some general principles from testing theory and then go into the practical application—live coding in a TDD manner.

Animation and Vue.js
There's a lot to gain from adding animations to your site or app. Beyond their visual appeal, you can guide the user's attention, cover up slow to load components and elements, and reveal sections of a page without the user wondering where it came from. This talk will cover the built-in ways Vue.js helps you animate your site, and how for more complicated animations you can hook into third party libraries. It'll also cover the basics of animation itself – what to animate, what not to animate – and how you can use animations to enhance your website without harming the experience of people with disabilities.
