request.cookies.set('show-banner', 'false')
get(name)

// 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')

request.cookies.has('experiments')
clear()
Remove the Set-Cookie
header from the request.

API with additional convenience methods, including Next.js specific properties.
// Given a request to /home, pathname is /home

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

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
}
