The first render of a Client Component happens on the server. This is called Server-side rendering (SSR). However, Client Components are synchronous, so they cannot suspend rendering while fetching data - such as the user's session. This means we either need to display a loading spinner or render the logged out state, while fetching that async data, causing a flash of incorrect state for the user.

In this lesson, we look at rendering a Client Component from a Server Component that can asynchronously fetch the user's Supabase session, and pass it as a prop to the Client Component, making the user's session available on its first SSR render.

Code Snippets

Render Client Component from Server Component

const {
  data: { session },
} = await supabase.auth.getSession();

return <ClientComponent session={session} />;
