Join Elio for a talk on mastering live coding demos. Learn to script your demos for seamless, error-free execution using Visual Studio Code and the Demo Time extension. Ideal for anyone performing live coding at conferences, webinars, or team meetings, this session will help transform your presentations from stressful to impressive.

Choosing the best framework is tough, isn't it? We've got Next.js, Remix, and a bunch of others thrown into the mix. So, let's keep it real in this talk—I'll be comparing three of the big contenders: Next.js, Remix, and one surprise package.We'll be looking at some key stuff like Data fetching, Routing, SEO, Performance, Server-side Rendering, and more. Think of it like a friendly showdown where these frameworks go head-to-head in a fair and square matchup.We'll dish out points and see who comes out on top, highlighting which framework rocks for different uses and helping you out with your next project. And hey, no favoritism here—I'll be keeping it neutral and backing it all up with real-world examples.

Have we been stuck in the same testing pain loops for years? Even though it might seem like it, we haven't!Even if AI is now writing our tests, many React developers have faced numerous challenges, from the unclarity of test classifications to the struggle of mocking, long-running integration tests, and shifting everything to E2E tests.Let's recap everything that has happened in the past years and look into the present to explore what 2025 will bring for testing in the React world around test runners, testing libraries, mocking, production practices, and AI-based tools.

Unlock the potential of geospatial data by combining React and deck.gl to create immersive web applications. This talk will demonstrate how to transform complex datasets into interactive, high-performance visualizations that captivate users. Whether you’re working on urban planning, environmental monitoring, or storytelling, learn how to elevate your projects with cutting-edge mapping technologies.

This talk introduces you to unconventional places where React can be rendered to solve problems outside the the boundaries of your browser window. It speciically dives into Productivity Plugins and Embedded Systems.

TiKevin83 details how he used next.js and webassembly (WASM) to port a speedrun-accurate Game Boy emulator onto the web. Topics include using emscripten to compile a C library into a WASM module, interfacing with a WASM module from a Next.js site, video and audio playback onto the canvas and audio APIs from a WASM module, and nuances of web control schemes especially in implementing multi-touch input.

Unlock the full potential of modern web applications with multi-threaded architectures in React. This session explores strategies for leveraging Web Workers and OffscreenCanvas to parallelise data processing, heavy computations, and UI rendering. We'll discover how to create interfaces that are scalable and unrestricted by conventional JavaScript bottlenecks.
