Next.js 12 has been released, bringing several exciting features, including a new Rust compiler for faster builds, React 18 support, native ESM support, and middleware support with Next/server. Middleware allows developers to run code before a request is completed, modifying the response based on user input. Native support for Edge Handlers and geolocation are also available, although in beta. The latest version of Next.js works seamlessly with Netlify, requiring zero configuration thanks to their open-source build plugin. Users can explore the community site for resources, tutorials, and forums for learning more about Next.js and getting help from experts.
