revalidatePath
revalidatePath allows you to purge cached data on-demand for a specific path.
Good to know:
revalidatePathis available in both Node.js and Edge runtimes.revalidatePathonly invalidates the cache when the included path is next visited. This means callingrevalidatePathwith a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited.
Parameters
revalidatePath(path: string, type?: 'page' | 'layout'): void;path: Either a string representing the filesystem path associated with the data you want to revalidate (for example,/product/[slug]/page), or the literal route segment (for example,/product/123). Must be less than 1024 characters.type: (optional)'page'or'layout'string to change the type of path to revalidate.
Returns
revalidatePath does not return any value.
Examples
Revalidating A Specific URL
import { revalidatePath } from 'next/cache'
revalidatePath('/blog/post-1')This will revalidate one specific URL on the next page visit.
Revalidating A Page Path
import { revalidatePath } from 'next/cache'
revalidatePath('/blog/[slug]', 'page')
// or with route groups
revalidatePath('/(main)/post/[slug]', 'page')This will revalidate any URL that matches the provided page file on the next page visit. This will not invalidate pages beneath the specific page. For example, /blog/[slug] won't invalidate /blog/[slug]/[author].
Revalidating A Layout Path
import { revalidatePath } from 'next/cache'
revalidatePath('/blog/[slug]', 'layout')
// or with route groups
revalidatePath('/(main)/post/[slug]', 'layout')This will revalidate any URL that matches the provided layout file on the next page visit. This will cause pages beneath with the same layout to revalidate on the next visit. For example, in the above case, /blog/[slug]/[another] would also revalidate on the next visit.
Server Action
app/actions.ts
'use server'
import { revalidatePath } from 'next/cache'
export default async function submit() {
await submitForm()
revalidatePath('/')
}Route Handler
app/api/revalidate/route.ts
import { revalidatePath } from 'next/cache'
import { NextRequest } from 'next/server'
export async function GET(request: NextRequest) {
const path = request.nextUrl.searchParams.get('path')
if (path) {
revalidatePath(path)
return Response.json({ revalidated: true, now: Date.now() })
}
return Response.json({
revalidated: false,
now: Date.now(),
message: 'Missing path to revalidate',
