Async Patterns

In Next.js 15+, params, searchParams, cookies(), and headers() are asynchronous.

Async Params and SearchParams

Always type them as Promise<...> and await them.

Pages and Layouts

type Props = { params: Promise<{ slug: string }> }

export default async function Page({ params }: Props) {
  const { slug } = await params
}

Route Handlers

export async function GET(
  request: Request,
  { params }: { params: Promise<{ id: string }> }
) {
  const { id } = await params
}

SearchParams

type Props = {
  params: Promise<{ slug: string }>
  searchParams: Promise<{ query?: string }>
}

export default async function Page({ params, searchParams }: Props) {
  const { slug } = await params
  const { query } = await searchParams
}

Synchronous Components

Use React.use() for non-async components:

import { use } from 'react'

type Props = { params: Promise<{ slug: string }> }

export default function Page({ params }: Props) {
  const { slug } = use(params)
}

generateMetadata

type Props = { params: Promise<{ slug: string }> }

export async function generateMetadata({ params }: Props): Promise<Metadata> {
  const { slug } = await params
  return { title: slug }
}

Async Cookies and Headers

import { cookies, headers } from 'next/headers'

export default async function Page() {
  const cookieStore = await cookies()
  const headersList = await headers()

  const theme = cookieStore.get('theme')
  const userAgent = headersList.get('user-agent')
}
