How can I pass data from middleware to frontend on solid-start.

I have this middleware to validate a user accesstoken. And the response provides me the name of the user and the validity of the token. While I handle the redirects if valid or not from the middleware. I would like to use the user name in the app layout. How could I pass it down to the client? I can't find a nice solution for it.

export default createMiddleware({
  onRequest: [
    async (event) => {
      const { pathname } = new URL(event.request.url);
      const isProtectedLoggedOut = protectedPathsLogOut.some((protectedPath) =>
        pathname.startsWith(protectedPath),
      );
      const isProtectedLoggedIn = protectedPathsLogIn.some((protectedPath) =>
        pathname.startsWith(protectedPath),
      );
      const accessToken = getServerCookie('access-token', event);
      if (accessToken) {
        const response = await fetchApi<GetUser>('/users', 'get', undefined, {
          authorization: `Bearer ${accessToken}`,
        });

        if (!response.success) {
          deleteCookie(event, 'access-token');

          if (isProtectedLoggedOut) {
            return sendRedirect(event, '/account/login');
          }
        }

        if (response.success) {
          if (isProtectedLoggedIn) {
            return sendRedirect(event, '/account/private');
          }

          event.locals.user = response.data;
        }
      } else if (isProtectedLoggedOut) {
        return sendRedirect(event, '/account/login');
      }
    },
  ],
});

export default createMiddleware({
  onRequest: [
    async (event) => {
      const { pathname } = new URL(event.request.url);
      const isProtectedLoggedOut = protectedPathsLogOut.some((protectedPath) =>
        pathname.startsWith(protectedPath),
      );
      const isProtectedLoggedIn = protectedPathsLogIn.some((protectedPath) =>
        pathname.startsWith(protectedPath),
      );
      const accessToken = getServerCookie('access-token', event);
      if (accessToken) {
        const response = await fetchApi<GetUser>('/users', 'get', undefined, {
          authorization: `Bearer ${accessToken}`,
        });

        if (!response.success) {
          deleteCookie(event, 'access-token');

          if (isProtectedLoggedOut) {
            return sendRedirect(event, '/account/login');
          }
        }

        if (response.success) {
          if (isProtectedLoggedIn) {
            return sendRedirect(event, '/account/private');
          }

          event.locals.user = response.data;
        }
      } else if (isProtectedLoggedOut) {
        return sendRedirect(event, '/account/login');
      }
    },
  ],
});

The information I'm interested in lives in response.data: event.locals.user = response.data; Any help will be appreciated. Thanks!!!

You can get the request event with getRequestEvent(); on the client
