getNextServerSideProps

The getNextServerSideProps function lets you server side render your page with WordPress data. The function should be returned from getServerSideProps which is required by Next.js to perform Server-Side Rendering (SSR):

export async function getServerSideProps(context: GetServerSidePropsContext) {
return getNextServerSideProps(context, {
Page: MyPage,
client,
});
}

The getNextServerSideProps function accepts two arguments: the server side props context, and an object (type GetNextServerSidePropsConfig) with a Page key. This should be your Next.js page component.

The reason MyPage and client are passed to getNextServerSideProps is because under the hood Faust.js performs a skeleton render of the page component to know what data to fetch and what queries to build. This allows the developer to not have to think about batching/constructing queries, or data fetching.

Context parameter​

This is the same object that Next.js provides in the getServerSideProps. You can read the list of parameters here.

GetNextServerSidePropsConfig parameter​

The second argument of getNextServerSideProps is of type GetNextServerSidePropsConfig and accepts the following parameters:

  • Page: The current page component. It can be any valid React Element.
  • client: The GQty client.
  • notFound: The notFound boolean allows the page to return a 404 status and 404 Page. This is used by Next.js to force a page return a 404 even if there was a successfully generated page before.
  • redirect: The redirect object allows redirecting to internal and external resources. It should match the shape of { destination: string, permanent: boolean }.
  • props: The props object is any other key value pairs of properties where each value is received by the Page component.

getNextServerSideProps return values​

The getNextServerSideProps function returns an object that is required by the getServerSideProps function.
