Cookies Example
You can read and write cookies directly on the edge and action as needed.
Demo
https://edge-functions-cookies.vercel.app
Since you can read cookies on the edge and rewrite the user to a statically generated page, eliminates the need of using getServerSideProps + redirect just to access the cookie, hence improving your site's performance and maintaining the same url.
The magic happens in the middleware.ts file:
import { NextRequest, NextResponse } from 'next/server'
export const config = { matcher: '/',}
export default function middleware(req: NextRequest) { // Parse the cookie const isInBeta = JSON.parse(req.cookies.get('beta')?.value || 'false')
// Update url pathname req.nextUrl.pathname = `/${isInBeta ? 'beta' : 'non-beta'}`
// Rewrite to url return NextResponse.rewrite(req.nextUrl)}How to Use
