Next.js 12 introduces a brand-new Rust compiler, Middleware (beta), React 18 Support, Native ESM Support, URL Imports, React Server Components (alpha), and more!

The Next.js Blog provides insights, updates, and tutorials on Next.js, a popular React framework for building server-side rendered (SSR) and static websites. Developers can learn about Next.js features, routing mechanisms, and data fetching strategies, as well as explore real-world examples and use cases of Next.js applications.

Next.js 12 includes a brand new Rust compiler that takes advantage of native compilation. We've optimized bundling and compiling with ~3x faster refresh locally and ~5x faster builds for production. Native Next.js APIs are now supported, as well as Suspense <Image /> AVIF Support.
