route.js

Route Handlers allow you to create custom request handlers for a given route using the Web Request and Response APIs.

HTTP Methods

A route file allows you to create custom request handlers for a given route. The following HTTP methods are supported: GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS.

export async function GET(request: Request) {}
 
export async function HEAD(request: Request) {}
 
export async function POST(request: Request) {}
 
export async function PUT(request: Request) {}
 
export async function DELETE(request: Request) {}
 
export async function PATCH(request: Request) {}
 
// If `OPTIONS` is not defined, Next.js will automatically implement `OPTIONS` and  set the appropriate Response `Allow` header depending on the other methods defined in the route handler.
export async function OPTIONS(request: Request) {}

Good to know: Route Handlers are only available inside the app directory. You do not need to use API Routes (pages) and Route Handlers (app) together, as Route Handlers should be able to handle all use cases.

Parameters

request (optional)

The request object is a NextRequest object, which is an extension of the Web Request API. NextRequest gives you further control over the incoming request, including easily accessing cookies and an extended, parsed, URL object nextUrl.

context (optional)

type Params = {
  team: string
}
 
export async function GET(request: Request, context: { params: Params }) {
  const team = context.params.team // '1'
}
 
// Define params type according to your route parameters (see table below)

Currently, the only value of context is params, which is an object containing the dynamic route parameters for the current route.

NextResponse

Route Handlers can extend the Web Response API by returning a NextResponse object. This allows you to easily set cookies, headers, redirect, and rewrite. View the API reference.
