Hi @brisk nymph. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Yes, you can make a Static Site Generation (SSG) route regenerate from within the application using a feature called Incremental Static Regeneration (ISR). This feature allows you to create or update static pages at runtime.

Here's an example of how you can use ISR in a dynamic route:

// This function gets called at build time
export async function getStaticPaths() {
 // Call an external API endpoint to get posts
 const res = await fetch('<https://.../posts'>)
 const posts = await res.json()
 
 // Get the paths we want to pre-render based on posts
 const paths = posts.map((post) => ({
 params: { id: post.id },
 }))
 
 // We'll pre-render only these paths at build time.
 // { fallback: false } means other routes should 404.
 return { paths, fallback: false }
}

export default function Post({ post }) {
 // Render post...
}
 
export async function getStaticPaths() {
 // ...
}
 
// This also gets called at build time
export async function getStaticProps({ params }) {
 // params contains the post `id`.
}

In the getStaticPaths function, you specify which paths you want to pre-render at build time. The fallback: false option means that other routes should return a 404 error.

In the getStaticProps function, you fetch the data for the post with the given id and use it to pre-render the page.

You can learn more about ISR in the Next.js documentation (https://nextjs.org/docs/pages/building-your-application/data-fetching/incremental-static-regeneration).

@low chasm is it possible to revalidatePath on pages router?

Let me check the knowledge base for you. One moment! :books:

#

Yes, it is possible to use revalidatePath with the pages router in Next.js. The revalidatePath function allows you to manually revalidate data and re-render the route segments below a specific path in a single operation.

Here's an example of how you can use revalidatePath:

import { revalidatePath } from 'next/cache'

revalidatePath('/')

You can use revalidatePath in two places depending on what you're trying to achieve:

  1. Route Handlers - to revalidate data in response to a third party event (e.g. webhook).
  2. Server Actions - to revalidate data after a user interaction (e.g. form submission, clicking a button).

However, it's important to note that revalidatePath only invalidates the cache when the included path is next visited. This means calling revalidatePath with a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited.

You can learn more about revalidatePath in the Next.js documentation (https://nextjs.org/docs/app/api-reference/functions/revalidatePath).
