You can read and write cookies directly on the edge and action as needed.
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 cookieconst isInBeta = JSON.parse(req.cookies.get('beta')?.value || 'false')// Update url pathnamereq.nextUrl.pathname = `/${isInBeta ? 'beta' : 'non-beta'}`// Rewrite to urlreturn NextResponse.rewrite(req.nextUrl)}
You can choose from one of the following two methods to use this repository:
Deploy the example using Vercel:
Execute create-next-app
with pnpm to bootstrap the example:
pnpm create next-app --example https://github.com/vercel/examples/tree/main/edge-middleware/cookies cookies
Next, run Next.js in development mode:
pnpm dev
Deploy it to the cloud with Vercel (Documentation).
