Ville is an inspired front end prodigy who started his deep dive into React Native over 3 years ago, and still hasn’t resurfaced. He’s a forward-leaning tech driver often found rambling about UX, accessibility, processes or psychology. Ville tends to get involved wherever anything regarding those could be improved. Currently, Ville works as a Senior Software Engineer and Web Tech Lead at Qvik. Spend a few minutes with him, you’ll learn something new!
⚡️ Hacking App Ratings #
React Native or React hybrid mobile apps are more prevalent than ever. Yet, the pitfalls of mobile can take many developers coming from the browser world by surprise. App store ratings are a notoriously impactful metric for every app out there, a metric that’s not easy to push into the higher ranks. Understanding the app store market is easy enough, but the industry secret lies in making a consistent rating system that hacks deep into the end user’s mind using psychology and great user experience – all in an ethical way. Learn the principles of how to get that 2,7 average star rating into 4,2 stars in no longer than two weeks, and fully in JS.

🎙 Taming UI complexity with finite state machines #
Most UI components are challenging on web. I asked people on Twitter about their opinion on what are the most challenging and complex UI components they know.
In the answers, there were Carousels, Async selects, etc. I took Carousel as an example and reviewed the implementation of some of the most popular open source ones. They had some bugs due to complexity of configs.
I tried to model the complexity using Finite state machines. When I was done, it was super solid and those computation bugs were gone as well. Since FSM gives you the graph of all possible combinations, I generated all the permutations, rendered all the possible variations of the carousel and tested them visually using Cypress and Percy.
Using this approach, you get to develop complex UI components, Manage their complexity using FSM and get to test them using property based testing techniques and get all the possible outputs visualized without a need to test them in your UI at all!

⚡️ How we made is.fi, Finland’s largest website faster, cleaner, and more accessible #
Full rewrite from scratch is almost always a bad idea. In most cases, the end result is barely better than the legacy service that was supposed to be renewed. However, in some cases a full rewrite is the only sensible option. That was our case when we took a critical look at our architecture and the amount of technical debt at Ilta-Sanomat web project. The project had grown over the years and was in a state where creating new features was slow, the code was not very maintainable and the performance was not at a desired level.
The decision was made, and we started rewriting the whole project from scratch, including the backend that provides the data. We rebuilt the site as a Server Side Rendered React application using Next.js while also renewing the design. For state management we only use React’s built-in tools, hooks and the Context API. A design system was also set up during the project in order to make sure the design and development will remain in sync in the future and the development faster and more enjoyable. Better performance and accessibility were the main goals of this renewal project. How did we achieve these goals despite the scale of the project and the amount of third party scripts and other requirements?

🎙 The Future of Real-time | Offline | Data #
Complexity, and the consistent attempts to reduce complexity, is at the core of the evolution of technology. As technology evolves, we then find harder problems to solve and are presented with new challenges. In the client space, we’ve seen innovation that has addressed how we deal with modern application concerns like real-time and offline data while at the same time GraphQL has continued to gain in market share.
What happens when we take the advancements that GraphQL has introduced as a paradigm and combine them with a mental model that all data should be local and offline first, with eventual consistency to your database as a second thought? In this talk, I’ll talk about a data store paradigm that allows developers to work with a single, local database and source of truth, and the idea that you should not have to make more than one write action to have (eventual) consistency across the client and server.

⚡️ React for Command-Line Interfaces! (feat. Ink) #
Text-based CLI tools are great. They are fast, lightweight, and universally accessible. But what does CLI have to do with React?
In this lightning talk, we will have a look at Ink - a wonderful custom React renderer that allows us to use Flexbox to create excellent command-line interfaces with ease. Want to create a companion CLI tool for the next big thing that you are working on? Build it with React!

🎙 What is the deal with i18n? #
While about 51% of the world’s websites are in English, only about 25% of web users are English speakers. With half of the world’s population online, internationalisation is as relevant as ever. Let’s explore what i18n means, how it gets made on the web and what we should keep in mind or avoid when making the web more accessible to the world.
