CSS Houdini & The Future of Styling | JSConf EU 2019

It’s almost here! Houdini — the future of CSS! This spec allows developers to write web worklets with JavaScript syntax and access the CSS Object Model for the very first time. Everything will change! In this talk, we’ll will walk through some of the visual magic we can create by using Houdini and its various upcoming browser APIs, and go through a live demo of how we can get started with implementation. Learn about how to use Houdini and what it means for the future of web application styling.

10 things I learned making the fastest js server runtime in the world | JSConf EU 2019

This presentation is about server performance, which means that no time in the world would be enough to cover it all. Hopefully, I can share with you the top #10 things I’ve learned while putting JavaScript on the top of the server side benchmarks. You will learn about runtimes and engines, how some are more capable than others, and sometimes the obvious choice is not always the right one… This talk is about thinking outside of the box, being creative and don’t take anything for granted. We will debunk myths about native code vs script or RAM usage, it’s going to be fast! I promise!

A sneak peek into super optimized code in JS frameworks | JSConf EU 2019

Very few developers have the need to write super optimized code. In application development we tend to favor readability over optimization. But that’s not the case with frameworks. Developers who use frameworks expect them to run as fast as possible. In fact, speed is often a defining characteristic when choosing a framework. There are techniques that make code run faster. You’ve probably heard about linked lists, monomorphism and bitmasks, right? Maybe you’ve even used some. Well, you can find all these and a bunch of other interesting approaches in the sources of most popular JS frameworks. Over the past year I’ve seen a lot while reverse-engineering Angular and React. In this talk I want to share my findings with you. Some of you may end up applying them at work. And others, who knows, may even end up writing the next big framework.

The economics of open source by C J Silverio JSConf EU 2019

The JS package commons is in the hands of a for-profit entity. We trust npm with our shared code, but we have no way to hold npm accountable for its behavior. A trust-based system cannot function without accountability, but somebody still has to pay for the servers. How did we get here, and what should JavaScript do now?
