I'll share our experience building RorkAI, an AI builder for fullstack React apps without code. It's like Replit meets Webflow/Framer. We're very early stage, but built a fully working prototype in 4 weeks, and we're proud to share our experience.
Questions we'll touch:

• Our experience building Cursor-like Composer for next with Claude and O1

• What turned out to be the best fullstack framework like Next, Remix or Tanstack Start

• How to create UI like Vercel's v0

• Share our experience of using Webcontainers, Nodebox and Sandpack

• how to avoid RAG errors & improve AI reliability

• how to make AI create authentication, database migrations, use Stripe, and external APIs (OpenAI, Replicate, etc.)

• what innovations in the JS world (not including) made RorkAI actually possible Our vision is that RorkAI will help non-technical founders build lots of new SaaS businesses with AI. We don't think AI will ever replace engineers for interesting tasks, we think it will replace outsource agencies. We help founders test business ideas faster and switch to in-house teams as they grow.

React Server Components (RSC) represent a powerful new paradigm for building fast, interactive web applications by allowing server-side rendering of components alongside client-side ones. While Next.js has emerged as a popular framework for leveraging RSC, it's not the only option.

In this talk, we'll explore how to integrate React Server Components into a custom application without relying on Next.js. You'll learn about the core concepts of RSC, the benefits of server-side rendering, and how to configure your own custom server environment to take full advantage of RSC in any React project. By the end, you'll walk away with a deep understanding of how React Server Components work independently of popular frameworks and how to apply them to improve performance and scalability in your applications.

We often shine a light on backend performance, closely tracking every request, service, and infrastructure element, but the frontend often doesn’t receive the same level of attention.

In this session, we’ll dive into how monitoring the frontend with Core Web Vitals and synthetics can provide meaningful insights into user behavior and application health. Core Web Vitals serve as benchmarks for the user experience, measuring key aspects like page load speed, interactivity, and visual stability. Meanwhile, synthetics let us simulate user journeys to proactively identify issues before they affect real users. Together, these tools bring essential visibility to the frontend, enabling data-driven decisions that genuinely improve the user experience.

This talk will explore how race conditions can lead to a broken experience for a seemingly simple UI interaction. I will show how I use a technique I call "chaos mode" to help me spot these race conditions, and I will cover some effective approaches to prevent those race conditions.
