Performance wins with React 18

React 18! Concurrent features! You might’ve already tried the new APIs like useTransition, or you might’ve just heard of them. But do you know how you can improve your application performance by using React 18 concurrency features?
The talk will focus on improving app performance using React 18 concurrent features.
I will go through multiple code examples and live demos to demonstrate the performance benefits.

Mo Frontends Mo Problems Mo Solutions

During the past one year I have been working on a project with Microfrontends using Turborepo deployed on Vercel for a client of Foolproof.
During that time we started this project, Module federation wasn't supported for Vercel and we had to find another way to make it work! During this talk I am sharing all the PROBLEMS that we came through, how eventually you can come around them and how you can eventually get to an Anti-Micro-frontend Patterns, for example as you try to get rid of the Monolith you end up going back to the Monolith! I will do a comparison with other solutions like Module Federation and different bundlers such as Vite, RSpack and explain the differences between all these!
I will also explain what are the overheads of running micro-frontends and the SOLUTIONS to ensure they run ok for your team.

Craig's Amazing Rust Spectacular (brought to you by Rust-eze)

Rust-eze is an American company owned by Dinoco.
It sells medicated bumper ointment for cars with rusty bumpers, to eradicate rust.
It was created by Rusty and Dusty Rust-eze and since then became recognized trademark in the United States.
Rust on the other hand is a multi-paradigm, general-purpose programming language.
Rust emphasizes performance, type safety, concurrency, and enforces memory safety. Rust is popular for systems programming but also offers high-level features! It's all the rage in Radiator Springs, and becoming the hottest way to build tools that go faster than Lightning McQueen 🏎️. Let's explore the language from the perspective of front-end engineers, see how it compares to TypeScript, and how it might influence the future of front-end.
🏁 Ka-chow! 🏁

Next.js Unleashed: Optimizing Web Vitals for superior User Experience

This talk focuses on Next.js, the hyped JavaScript framework developed by Vercel.
Specifically, I address how Next.js features such as Image Optimization and Dynamic Imports impact practical applications. To do this, I measure the web vitals of a sample application and optimize them using Next.js features. By this, we will find out of what specific benefits individual optimizations in our new favorite frontend framework have and what we should focus on.
Come & join if you want to gain practical insights and actionable strategies for maximizing website performance and user engagement through the lens of Next.js and Web Vitals!

Exploring the Enigmatic: Navigating JavaScript's Uncharted Realms

Delve into the depths of advanced JavaScript features that often remain shrouded in mystery. Join us as we unravel the complexities of Symbols, WeakMap, WeakSet, and the art of Metaprogramming.

In this session, we'll demystify Symbols, showcasing how they transcend traditional properties, enabling the creation of private and immutable members. WeakMap and WeakSet will take the stage, offering insights into memory management.

Metaprogramming, the crown jewel of this journey, will empower you to transcend ordinary coding. Witness how code can be generated, modified, and customized programmatically, opening doors to efficient, dynamic, and elegant solutions.

We aim to equip you with the knowledge to effectively wield these features, elevating your JavaScript prowess. Whether you're an aspiring developer or an experienced coder, join us in unravelling JavaScript's enigmatic potential.

Do we need it?

For the past decade, Javascriptland has been flourishing, and we had the privilege to learn how to work with an ever evolving landscape of tools, frameworks and practices.
But there's an obvious dark side to it, and it's not only the FOMO on the new shiny thing, but also an actual organizational cost associated to it.
This talk analyzes the costs of tech decisions, not in a "budget sheet" sort of way, but building a narrative that touches on team and company impact of tech choices.

“Adding accessibility” made it worse - but why?"

Accessibility is becoming a significant topic in the next year, as US and European laws are forcing a lot of industry fields to adjust their websites to become overall accessible.
However, product improvements are always first, and features must be released, so let’s add some accessibility in the end, right?

Totally no! Let’s go through the process of what it takes to make a website more accessible. We will understand certain pitfalls and typical mistakes developers make when working on accessibility and see how to improve accessibility without starting our whole project from scratch.
