Hi @atomic talon. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
In Next.js, you can access the dynamic route parameters of the current URL using the useParams hook or the params prop in a layout component.
If you're in a client component, you can use the useParams hook to get the dynamic route parameters. Here's an example:
'use client'
import { useParams } from 'next/navigation'
export default function ExampleClientComponent() {
const params = useParams()
// Route -> /shop/[tag]/[item]
// URL -> /shop/shoes/nike-air-max-97
// `params` -> { tag: 'shoes', item: 'nike-air-max-97' }
console.log(params)
return <></>
}
In this example, useParams returns an object with the dynamic route parameters filled in by the current URL. The route /shop/[tag]/[item] matches the URL /shop/shoes/nike-air-max-97, so params is { tag: 'shoes', item: 'nike-air-max-97' }.
If you're in a layout component, you can access the dynamic route parameters through the params prop:
export default function ShopLayout({
children,
params,
}: {
children: React.ReactNode
params: {
tag: string
item: string
}
}) {
// URL -> /shop/shoes/nike-air-max-97
// `params` -> { tag: 'shoes', item: 'nike-air-max-97' }
return <section>{children}</section>
}
In this example, the params prop contains the dynamic route parameters from the root segment down to the layout. The URL /shop/shoes/nike-air-max-97 matches the route app/shop/[tag]/[item]/layout.tsx, so params is { tag: 'shoes', item: 'nike-air-max-97' }.

@nova veldt is there a way to maintain the ssr while getting all of the params
nova veldtBOT
Let me check the knowledge base for you. One moment! :books:
Yes, you can maintain Server-Side Rendering (SSR) while getting all of the parameters. In Next.js, you can use the getServerSideProps function to fetch data on each request and pass it to your page's props. This function runs on the server-side, so it's perfect for SSR.
Here's an example of how you can use getServerSideProps to fetch data based on URL parameters:
export async function getServerSideProps(context) {
const { params } = context;
// params contains the route parameters for pages using dynamic routes
// For example, if the page name is [id].js , then params will look like { id: ... }
const data = await fetchDataBasedOnParams(params);
// Pass data to the page via props
return { props: { data } };
}
export default function Page({ data }) {
// Render your page with data
}
In this example, getServerSideProps fetches data based on the URL parameters (params) and passes it to the page as a prop. The page then renders with this data.
Remember, if you add getServerSideProps to a page, Next.js will pre-render this page on each request using the data returned by getServerSideProps.

@nova veldt with app router
nova veldtBOT
Let me check the knowledge base for you. One moment! :books:
In the new App Router model of Next.js, you can use the params prop in your layout component to access the dynamic route parameters. This works for both static and dynamic rendering.
Here's an example of how you can use the params prop in a layout component:
export default function Layout({ params }) {
// params contains the route parameters for pages using dynamic routes
// For example, if the page name is [id].js , then params will look like { id: ... }
// You can now use these params to fetch data, render different components etc.
}
In this example, params contains the dynamic route parameters from the root segment down to the layout. You can use these parameters to fetch data, conditionally render components, etc.
For dynamic rendering, you can set the dynamic route segment config option to force-dynamic. This forces the page to be dynamically rendered, and the params prop will be available on the server during the initial server render of the Client Component.
