Remix is a full-stack web framework that helps developers achieve stellar user experiences with tools like nested routes, parallel data requests, and built-in error handling. It aims to eliminate slow loading states and "jankiness" in web apps. Edge Functions allow deploying code closer to site visitors globally, enabling Middleware use cases like localization and authentication, and can be used to deploy entire applications to the edge. By using Remix with Netlify Edge Functions, developers can take advantage of server-side rendering, React 18 streaming, and a truly open ecosystem that's standards-based.
