Middleware
This example shows how to use Middleware in Next.js to run code before a request is completed.
The index page (app/page.tsx) has a list of links to pages with redirect, rewrite, or normal behavior.
On the Middleware file (middleware.ts) the routes are already being filtered by defining a matcher on the exported config. If you want the Middleware to run for every request, you can remove the matcher.
Deploy your own
Deploy the example using Vercel:
How to use
Execute create-next-app with npm, Yarn, or pnpm to bootstrap the example:
npx create-next-app --example middleware middleware-app
yarn create next-app --example middleware middleware-app
pnpm create next-app --example middleware middleware-app
Deploy it to the cloud with Vercel (Documentation).
