Best Approach for Prefetching Multiple Queries in Apollo with Next.js?

[naimulemon]

I’m working with Apollo Client in a Next.js 14 project and trying to prefetch multiple GraphQL queries using PreloadQuery. I want to ensure that this is the correct approach for prefetching multiple queries and handling the data efficiently within the component.

const IndexPage: React.FC = () => {
  return (
    <>
      <ApolloWrapper>
        <PreloadQuery query={ProductDocument}>
          <PreloadQuery
            query={gql(`query ProductDiscount($productId: Int!) {
  productDiscount(productId: $productId) {
    id
    discount
    offerTitle
  }
}`)}
          >
            <Suspense fallback={<div>Loading...</div>}>
              <ProductComponent />
            </Suspense>
          </PreloadQuery>
        </PreloadQuery>
      </ApolloWrapper>
    </>
  );
};

Is this a recommended way to prefetch multiple queries using PreloadQuery? Are there more efficient or cleaner alternatives for handling multiple queries in this scenario, particularly with regards to code readability and performance?

The general advice would be to use fragment colocation to compose all your data needs into one query, but if you are using more than one query per router, you're already doing it right.
