Talks:

Let’s Talk About Re-renders

Let’s Talk About Re-renders
By Nadia Makarevich

React is a fantastic tool to implement complicated applications fast, we all know it. But are they going to be fast when implemented fast? Let’s talk about re-renders and their danger in react: how easy it is to make a mistake, why some small mistakes can have a huge downstream effect, and how to avoid and prevent them. This is a deep-dive type of talk, that focuses on why React components re-render, what kind of performance impact it can have, and what to do about it.

Punkbase - SQL.js In Action

Punkbase - SQL.js In Action
By Gerald Bauer

Query punkbase.db with SQL online using "server-less" web page thanks to SQL.js

What is punkbase.db? Single-File SQLite Database, that is, punkbase.db - about ~5MB. With 10 000 records of the punk pixel art collection with all metadata (e.g. base type, skin tone, gender, head, eyes, etc.).

What is SQL.js? SQLite compiled to JavaScript that runs - yes - in your browser (web page) "server-less"! Source code in C compiled via Emscripten (to WebAssembly, really ;-).

The other JavaScript performance (no one is talking about)

The other JavaScript performance (no one is talking about)
By Miroslav Jonas

Web Application performance has been hot topic for quite some time. Bundle splitting, lazy loading, preloading images, SSR, hydration, islands... All of these topics revolve around FCP, FMP, TTI.

But what if your application was loaded fast, but then it's still slow? And what if it's a node library and all of the above doesn't apply at all?

In this short talk I will show you some tricks on how to speed up your critical parts of code and how to easily measure the runtime performance. We will talk about JavaScript native functions and Order notation, but don't worry, you don't need a degree in CS to follow along.
