Real case: a 50-route app dropped from ~4.6GB to ~840MB RAM<br> Up to 5.5x faster repeat builds, thanks to the same disk cache now working with next build too<br> Up to 22% more requests under load - SSR moved from Web Streams to native Node.js streams<br> TypeScript 7-10x faster type checking<br> Edge runtime is now officially deprecated<br> Separately - Instant Navigations, opt-in features rethinking navigation in server-driven apps:<br> → Partial Prefetching - instead of an aggressive full-page prefetch on every link, one reusable "shell" per route, cached for the session → Instant Insights - a devtool that automatically catches navigations that weren't instant and hands you a fix prompt → Better ISR - pages without a build-time prerender now show an instant shell to the first visitor instead of a blocking load → Navigation Inspector - visual debugging of loading states in dev → Playwright helper instant() - catches regressions when a navigation stops being instant after a refactor<br> This will become the default in the next major version - worth a look now.<br> <a href="https://lnkd.in/dXMz9jYH" rel="noopener noreferrer">https://lnkd.in/dXMz9jYH</a></p> <h1> nextjs #frontend #webdev #reactjs </h1> nextjs performance react webdev
