2022 saw the rise of new paradigms, from Qwik to SolidJS to SvelteKit 1.0. This talk explores the current and predicted state of frontend frameworks and enables engineers to be in the loop and make the best choice for their teams.

The modern frontend ecosystem (keynote)

Learn a new concept to start your developing process - advanced XState for complex State Management in modern web applications, and start building complex architecture visually!

Visualize your State Management with XState

As Front-end developers, we all know that forms can get really messy, but what if I told you that there is a library out there that can make your life much easier. In this talk, I'll introduce react-hook-form, a library that started to gain more and more popularity. It is super light, intuitive, performant, and flexible with easy-to-use validation. We'll cover its basics through a live code example and learn about its benefits. In addition, I will share with you my thoughts about what to look for when choosing a library to use.

Get your forms hooked with react-hook-form

Let's face it, there are many advantages to using GraphQL compared to REST APIs. But if you strip it down to the network protocol, it's using HTTP just as REST. We developers need to write a lot of imperative code to retrieve data to display in our applications and handle state. With GraphQL you can, when using the correct libraries, decrease the amount of code needed around data fetching and state-management. Next to increased flexibility, better performance and most of all an improved developer experience. In this talk I show GraphQL's magic and how (in the end) it's just HTTP.

GraphQL is just HTTP

Lunch Break

What can software developers learn from doctors, scientists and martial artists? During my years as a developer I’ve written lots of software. Ranging from data related like image processing, sound analysis and synthesis, and data analysis to working on fullstack web applications. I’ve picked up some skills in various fields like performance, design patterns and devops. In this talk I’m going to share with you the one thing that makes me a better developer than my younger self - automated tests. You will learn how tests can improve your code, how to write better tests, how to use code coverage and how it is all related to medicine, housekeeping work and martial arts.

Test Drive Your Code

How did we create our game framework with React + Redux and build dozens of games? How we have solved problems of introducing new tech to large codebases and connecting Redux and Mobx.

How do we build games? Connecting past, present and future

Discover effective techniques that teams can utilize to enhance their performance, which are frequently neglected amidst the hustle and bustle of scrum ceremonies and docker containers.

The magic of continuous delivery

Let's face it, understanding a long page of specs is not always a trivial task to do. Same as building a complex component system. Let's explore how we can combine visualization and composition API to create our reusable and visual-able logic system for your components, ready to use in Vue application.

The art of visualization and composition in building component systems.

There is a saying that the best way to learn something is to teach it to someone else. When we write a tech blog, we share our knowledge with others and deepen our understanding of the subject. We also improve other skills along the way and build our professional brand and signature.In this talk, we will discuss the benefits of writing a blog and try to remove all the barriers that have stopped us so far from writing a blog.

Channeling your inner tech blogger
