Middleware vs. Higher-Order Components in Next.js
An architectural deep dive into when you should use Edge Middleware instead of React HOCs for routing and authentication logic.
import type { NextRequest } from 'next/server';
export function middleware(request: NextRequest) { const token = request.cookies.get('auth_token');
if (!token && request.nextUrl.pathname.startsWith('/dashboard')) { return NextResponse.redirect(new URL('/login', request.url)); } } ```
Because Edge Middleware executes before the Next.js server even begins parsing React, the routing intercepts are instantaneous and highly secure.
