How do you handle redirects and rewrites in Next.js?

Q: How do you handle redirects and rewrites in Next.js?

**TL;DR.** Define **static** redirects() / rewrites() in next.config.js (a **redirect** changes the URL; a **rewrite** proxies internally while keeping the URL). For **dynamic/conditional** cases use **middleware** ( NextResponse.redirect/rewrite ) or call redirect() inside Server Components/Actions. redirect /old → /new URL changes (301/308) browser navigates <text class='d-text' x='340' y='54

Config rules + conditional middleware

// next.config.js — static
async redirects() { return [{ source: '/blog/:slug', destination: '/posts/:slug', permanent: true }]; }
async rewrites() { return [{ source: '/api/:p*', destination: 'https://backend/:p*' }]; }  // proxy

// middleware.ts — conditional
import { NextResponse } from 'next/server';
export function middleware(req) {
  if (req.geo?.country === 'FR') return NextResponse.rewrite(new URL('/fr', req.url));
}
