Bun 1.4 Rewrites the Runtime in Rust — Week 34 JavaScript

Next.js 16.3 combines Cache Components and Partial Prefetching to make server-rendered routes feel immediate. A route keeps a prerendered shell of static, cached, and fallback UI, and visible links can prefetch that shell before a click. Dynamic content still renders on the server and streams through Suspense, preserving Server Component boundaries rather than recreating the page as a client-only SPA. Cached reads can use use cache, cacheLife, and tags so revisits skip unnecessary work while mutations invalidate the right payload. The pattern succeeds only when the shell is useful on its own and the team defines freshness explicitly.

Oxlint now ships 22 React Compiler-powered rules that reuse the compiler's validation passes to find violations of React's rules. The new oxc-transform-react package applies automatic memoization and integrates with @vitejs/plugin-react 6.1 for Vite 8. Oxc's preliminary benchmark reports more than tenfold faster transforms than Babel, taking representative files from roughly 100 ms to 10 ms. The team achieved the result after an initial integration added more than 5 MiB to the binary, then separated framework-specific wiring from the vendor-neutral core. Teams should enable validation first, then benchmark the transform on their own build and dependency graph.
