Next.js ships with Route Handlers which provides an easy solution to build your own API. This example shows how to create multiple API endpoints with serverless functions, which can execute independently.

Deploy the example using Vercel or preview live with StackBlitz

Execute create-next-app with npm, Yarn, or pnpm to bootstrap the example:

npx create-next-app --example route-handlers route-handlers-app

yarn create next-app --example route-handlers route-handlers-app

pnpm create next-app --example route-handlers route-handlers-app

Deploy it to the cloud with Vercel (Documentation).
