Middleware and Edge Functions
Next.js 13 expands its middleware capabilities, allowing developers to run code at the edge, closer to the end-user. This is particularly beneficial for applications that require real-time data processing and customization.
Syntax:
// middleware.js
import { NextResponse } from 'next/server';
export function middleware(request) {
const url = request.nextUrl.clone();
if (url.pathname === '/') {
url.pathname = '/home';
return NextResponse.redirect(url);
}
return NextResponse.next();
}
// next.config.js
module.exports = {
experimental: {
middleware: true,
},
};
Key Features:
- Edge Middleware: Run middleware on Vercel’s Edge Network for ultra-low latency.
- Flexible API: Write middleware in JavaScript or TypeScript, enabling dynamic request handling.
- Advanced Caching: Leverage advanced caching strategies to optimize response times and reduce server load.
