New Trends in Front-End Development (and What We Can Learn from them)
summary
Shows a live BFF prototype using Bun + Express and React DOM server to stream HTML via renderToPipeableStream so the page loads with full data and no client JS until bootstrapped, proving server rendering cuts round trips and avoids leaking tokens. Benchmarks compare virtual DOM re-renders on a 10,000-item component to signal-based updates (Solid) and memo in React, demonstrating far fewer re-renders. Highlights Qwik’s on-demand handlers and Qwik ships ~1KB first-load, BFF renders on the edge, and recommends Astro for mixed-framework islands.
