Hi @undone drift. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The knowledge sources only show how to use Supabase auth from Astro server code and API routes, not from a React client component, so I can’t see exactly how to keep the React-side client in sync with the authenticated session. [Supabase guide]

From the docs, the recommended pattern is:

• Do all auth (sign in / sign out) via Astro API routes that set sb-access-token and sb-refresh-token cookies. [Auth endpoints]
• On protected pages (e.g. dashboard.astro), read those cookies on the server, call supabase.auth.setSession() with them, and then use the returned session to know the user and allow actions like “Sign out” or other authenticated operations. [Creating auth pages]

Example from the docs:

// src/pages/dashboard.astro
---import Layout from "../layouts/Layout.astro";
import { supabase } from "../lib/supabase";

const accessToken = Astro.cookies.get("sb-access-token");
const refreshToken = Astro.cookies.get("sb-refresh-token");

if (!accessToken || !refreshToken) {
  return Astro.redirect("/signin");
}

let session;
try {
  session = await supabase.auth.setSession({
    refresh_token: refreshToken.value,
    access_token: accessToken.value,
  });

  if (session.error) {
    Astro.cookies.delete("sb-access-token", { path: "/" });
    Astro.cookies.delete("sb-refresh-token", { path: "/" });
    return Astro.redirect("/signin");
  }
} catch (error) {
  Astro.cookies.delete("sb-access-token", { path: "/" });
  Astro.cookies.delete("sb-refresh-token", { path: "/" });
  return Astro.redirect("/signin");
}

const email = session.data.user?.email;

<Layout title="dashboard">
<h1>Welcome {email}</h1>
<p>We are happy to see you here</p>
<form action="/api/auth/signout">
<button type="submit">Sign out</button>
</form>
</Layout>

What’s missing in the docs is any example of:

- Using that authenticated Supabase client directly inside a React component, or
- Doing file uploads from React with the authenticated user.

So, based only on the docs:

- Supabase auth is demonstrated only in server-side Astro pages and API routes.
- There is no documented pattern here for sharing the authenticated Supabase client with React components or for doing authenticated file uploads from React.

Because of that, I can’t reliably tell you how to make your React component see the authenticated state using the provided `src/lib/supabase.ts`, nor how to wire file uploads from React in this setup, without going beyond the docs.

If you can move the upload logic to an Astro API route, you *can* keep it within the documented pattern: the route will see the auth cookies and can use `supabase` server-side to perform the upload on behalf of the logged-in user, similar to how `dashboard.astro` uses `setSession()`. [[Creating auth pages](<https://docs.astro.build/en/guides/backend/supabase/#creating-auth-pages>)]

But the knowledge sources do not show the exact code for:

- A file-upload API route using Supabase, or
- A React component calling Supabase directly with the authenticated session.

So I’m not able to give a precise, doc-backed fix for your React component.
