[EN] "TS in CSS" - Aleksandra Sikora, Hasura

It's about time we stopped worrying too much about CSS. Instead, let's think about how we can harness the power of TypeScript to write maintainable styles. During this talk, I will show why CSS-in-JS libraries are cool and how to use TypeScript to enhance your developer experience regarding CSS.

[EN] "Refinement Types" - Piotr Monwid-Olechnowicz, Chop-Chop

I’m gonna explain what refinement types are, geek out about a research paper that adds them to the TypeScript type system, and live-code a userland refinement type you can already use in your codebase.

[EN] "Code analysis and visual code representation" - Mateusz Strąg, VirtusLab

Current IDEs are dynamically evolving, however, we are all forced to browse code by looking at flat-file structures No information about the semantic dependencies between different units. I will show how to browse code graphically and clearly visualize semantic dependencies in TypeScript project which would result in speeding up the process of learning and understanding the code

Software engineer mainly focused on data visualization on a fronted side. Involved in whole VirtusLab R&D department which results in publishing first extensions on a marketplace.
