How to pass headers while using `getServerSideProps`

[Krzysztof Nofz]

We want to prefetch data by using getServerSideProps. Do we really need to pass headers directly to graphql.request function? Is it possible that following code may work?

export const getServerSideProps = (async context => {
  const { id: postId } = context.query;
  
  const headers = context.req.headers;
  const accessToken = headers['app_header'];

  context.res.setHeader('new_header', accessToken);

  const data =  await graphQLClient.request(query, { postId });

  return data;
}) satisfies GetServerSideProps;

I wouldn't like to pass headers as second argument to the function, since we use react-query ( and we would need to disable eslint deeps rule ).

If someone is interested, I noticed that graphql-request adds possibility to setHeader directly to the object..

export const getServerSideProps = (async context => {
  const { id: postId } = context.query;
  
  const headers = context.req.headers;
  const accessToken = headers['app_header'];

  graphQLClient.setHeader('new_header', accessToken); <--- this line

  const data =  await graphQLClient.request(query, { postId });

  return data;
}) satisfies GetServerSideProps;

Closing this issue :)
