🚀 Major Performance Breakthrough: Early Hydration React on Rails now starts hydration even before the full page is loaded! This revolutionary change delivers significant performance improvements across all pages: Eliminates Race Conditions: No more waiting for full page load before hydration begins Faster Time-to-Interactive: Components hydrate as soon as their server-rendered HTML reaches the client Streaming HTML Optimization: Perfect for modern streaming responses - components hydrate in parallel with page streaming Async Script Safety: Can use async scripts without fear of race conditions No More Defer Needed: The previous need for defer to prevent race conditions has been eliminated This optimization is particularly impactful for: Streamed pages where content loads progressively Large pages with many components Slow network conditions where every millisecond counts Modern web apps requiring fast interactivity.
