How to set `returnTo` for SSR for a dynamic route?

Help

Please include the following information in your post:

  • Which SDK this is regarding: @auth0/nextjs-auth0
  • SDK Version: 1.7.0
  • Platform Version: Node v17.1.0 (on macOS 12.2)
  • Code Snippets/Error Messages/Supporting Details/Screenshots:

Is this a feature request or bug report? No.

I am following the instructions referenced here for an SSR protected page.

I am using this snippet with a fresh/clean install of NextJS (version 12.0.10):

export const getServerSideProps = withPageAuthRequired({
  async getServerSideProps(ctx) {
    console.log("query", ctx.query);
    // This was in the documentation but doesn't seem to be needed:
    // https://auth0.github.io/nextjs-auth0/modules/helpers_with_page_auth_required.html#withpageauthrequiredoptions
    //
    // const session = getSession(ctx.req, ctx.res);
    return { props: { customProp: "bar" } };
  },
});

I am trying to link to a route /test/[id].tsx

This functions correctly when I omit returnTo but it changes the URL to: http://localhost:3000/test/something?id=something instead of http://localhost:3000/test/something

If I set the returnTo value to /test/something the URL is fine.

Is there a way to set the returnTo dynamically? Or am I doing something incorrect? Or is it just something I will have to live with?

Thanks a lot!
Marc

Based on the README for nextjs-auth0 repository, it seems like it’s possible to do something like this, although I’m not sure it is recommended (just to get a prettier URL):

const getReturnTo = (
  ctx: GetServerSidePropsContext<ParsedUrlQuery, PreviewData>
) => {
  // Lots of better/different ways to do this
  const [path] = ctx.resolvedUrl.split("?");

  return path;
};

export const getServerSideProps: GetServerSideProps = (ctx) => {
  const returnTo = getReturnTo(ctx);

  return withPageAuthRequired<{ customProp: string }>({
    returnTo,
    async getServerSideProps(ctx) {
      return { props: { customProp: "bar" } };
    },
  })(ctx);
};

Hey there marclemagne!

I guess in this case it will be worth discussing with the SDK maintainer through a GitHub issue so they can share their thoughts. Would you be able to create one and share it here so we can ping them? Thanks!
