Eric Rasmussen discusses React beyond the DOM, React PDF, Ink tools, and rendering to Markdown. The overview includes React Reconciler, host configuration, state management with real-world entities like light bulbs, and building a traffic light state machine visually. The talk also covers securing third-party JavaScript, expanding React rendering possibilities, advanced tooling for state machines, controlling light bulbs via renderer callbacks, server functions for fetch in the cloud, and potential robot programming with React.

Akash Hamilwasia presenting at React Summit 2025, shares React Compiler learnings and works on an AI audio platform. Memoization in React helps optimize UI performance by preventing unnecessary re-renders. React Compiler offers automatic memoization through static code analysis. React rules emphasize purity and immutability. The compiler analyzes and memoizes code changes for optimization. React Compiler package usage improves performance through code analysis. Understanding reactivity issues is crucial for handling React state. Compiler optimization requires correct dependency arrays and usage of external libraries. Measure React Compiler impact using React Profiler for optimization and real user impact analysis.

One of the exciting things about web development is that the underlying technology that we use is constantly evolving. It’s hard to believe, but Server Components, partial hydration and hybrid rendering are no longer experimental features and are here to stay. With more projects adopting these ne...
