NextRequest

NextRequest extends the Web Request API with additional convenience methods.

cookies

Read or mutate the Set-Cookie header of the request.

set(name, value)

Given a name, set a cookie with the given value on the request.

// Given incoming request /home
// Set a cookie to hide the banner
// request will have a `Set-Cookie:show-banner=false;path=/home` header
request.cookies.set("show-banner", "false");

get(name)

Given a cookie name, return the value of the cookie. If the cookie is not found, undefined is returned. If multiple cookies are found, the first one is returned.

// Given incoming request /home
// { name: 'show-banner', value: 'false', Path: '/home' }
request.cookies.get("show-banner");

getAll()

Given a cookie name, return the values of the cookie. If no name is given, return all cookies on the request.

// Given incoming request /home
// [
//   { name: 'experiments', value: 'new-pricing-page', Path: '/home' },
//   { name: 'experiments', value: 'winter-launch', Path: '/home' },
// ]
request.cookies.getAll("experiments");
// Alternatively, get all cookies for the request
request.cookies.getAll();

delete(name)

Given a cookie name, delete the cookie from the request.

// Returns true for deleted, false is nothing is deleted
request.cookies.delete("experiments");

has(name)

Given a cookie name, return true if the cookie exists on the request.

// Returns true if cookie exists, false if it does not
request.cookies.has("experiments");

clear()

Remove the Set-Cookie header from the request.

request.cookies.clear();

nextUrl

Extends the native URL API with additional convenience methods, including Next.js specific properties.

// Given a request to /home, pathname is /home
request.nextUrl.pathname;
// Given a request to /home?name=lee, searchParams is { 'name': 'lee' }
request.nextUrl.searchParams;

The following options are available:

Property	Type	Description
basePath	string	The base path of the URL.
buildId	string | undefined	The build identifier of the Next.js application. Can be customized.
pathname	string	The pathname of the URL.
searchParams	Object	The search parameters of the URL.

Note: The internationalization properties from the Pages Router are not available for usage in the App Router. Learn more about internationalization with the App Router.

ip

The ip property is a string that contains the IP address of the request. This value can optionally be provided by your hosting platform.

Good to know: On Vercel, this value is provided by default. On other platforms, you can use the X-Forwarded-For header to provide the IP address.

// Provided by Vercel
request.ip;
// Self-hosting
request.headers.get("X-Forwarded-For");

geo

The geo property is an object that contains the geographic information of the request. This value can optionally be provided by your hosting platform.

Good to know: On Vercel, this value is provided by default. On other platforms, you can use the X-Forwarded-For header to provide the IP address, then use a third-party service to lookup the geographic information.

// Provided by Vercel
request.geo.city;
request.geo.country;
request.geo.region;
request.geo.latitude;
request.geo.longitude;

// Self-hosting
function getGeo(request) {
  let ip = request.headers.get("X-Forwarded-For");
  // Use a third-party service to lookup the geographic information
}
