Next.js ships with API routes which provides an easy solution to build your own API
.
This example shows how to create an API
endpoint with CORS headers, using the cors package.
Deploy the example using Vercel or preview live with StackBlitz
Execute create-next-app
with npm, Yarn, or pnpm to bootstrap the example:

yarn create next-app --example api-routes-cors api-routes-cors-app
pnpm create next-app --example api-routes-cors api-routes-cors-app
