Hi @tawny laurel. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Based on the provided extracts, there is no specific information about whether fetch requests in getServerSideProps are processed through middlewares in Next.js 13.4.
However, it's important to note that getServerSideProps runs only on the server-side and never on the browser. When a page uses getServerSideProps, the function runs at request time for each request, and the page will be pre-rendered with the returned props.
Here is an example of how getServerSideProps is used to fetch data:
export async function getServerSideProps() {
// Fetch data from external API
const res = await fetch(`<https://.../data`>)
const data = await res.json()
// Pass data to the page via props
return { props: { data } }
}
For more detailed information about getServerSideProps, you can refer to the Next.js documentation (https://nextjs.org/docs/pages/building-your-application/data-fetching/get-server-side-props).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@civic plume How can I consume middleware functionality in getServerSideProps?

Let me check the knowledge base for you. One moment! :books:
Based on the provided extracts, there is no direct information about consuming middleware functionality within getServerSideProps.
However, Next.js 13.1 introduced advanced Middleware where you can return responses from Middleware, as well as set headers on the request. This gives you the flexibility to customize every part of the Next.js routing lifecycle. Here is an example of how you can use middleware:
import { NextResponse } from 'next/server';
export function middleware(request: Request) {
// Check if a user has access...
if (!isAuthorized(request)) {
return NextResponse.json({ message: 'Unauthorized' });
}
// Add a new header, this will change the incoming request headers
// that you can read in getServerSideProps and API routes
const requestHeaders = new Headers(request.headers);
requestHeaders.set('x-version', '13.1');
return NextResponse.next({
request: {
// Apply new request headers
headers: requestHeaders,
},
});
}
In the context of getServerSideProps, it's important to note that it runs on the server-side and is used to fetch data at request time. This function can directly call a CMS, database, or other API, and it's not recommended to call an API route from getServerSideProps as it can cause an extra request and reduce performance.
