Remix — Full-Stack Web Framework on Web Fundamentals

What Remix Does

• Nested routing — file-based with nested layouts
• Server loaders — data fetched on server before render
• Actions — form POST handlers (works without JS)
• Forms — <Form> component with native HTML semantics
• Error boundaries — per-route error handling
• Optimistic UI — via useFetcher
• Edge deploy — Vercel, Cloudflare, Deno, Node

Architecture

File-system routing in app/routes/. Each route exports loader (server data), action (mutations), and default component (UI). Remix streams server responses and hydrates progressively. No client-side data fetching needed for initial render.

Self-Hosting

FAQ

Q: Remix or Next.js — which should I choose? A: Pick Remix if you want to stick close to web standards (Request/Response, Form); pick Next for the ecosystem and RSC. After 2024, Remix v3 has been merged into React Router v7.

Q: Does it support static generation? A: It's primarily SSR, but you can use a prerender plugin for SSG.

Q: Can it work without JS? A: Yes. Form + loader/action natively support a no-JS fallback.
