fix(web): prevent register page crash when Supabase config is not ready - #985
Conversation
Prevent uncaught 'supabaseUrl is required' when users submit before /private/config loads or when Vite env vars are absent in the client bundle. - Await getRemoteConfig() and disable submit until config is ready - Show Toastify error instead of calling useSupabase() without credentials - Make getLocalConfig() null-safe and guard useSupabase() with a clear error - Add regression tests for config parsing and readiness checks Co-authored-by: Martin DONADIEU <martindonadieu@gmail.com>

Environment values are normalized, project IDs are parsed safely, remote configuration requests time out, and signup failure paths restore the form state. ChangesSupabase registration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Registration may remain disabled on browsers that do not support AbortSignal.timeout when local Supabase credentials are unavailable; adding a fallback or declaring a supported browser range is a bounded follow-up.

In `@apps/web/src/pages/register.astro`:
- Around line 172-180: Update the configReady handler in register.astro to
explicitly detect invalid resolved configuration, invoke showConfigError(), and
preserve the disabled submit state; also add an abort deadline to the
/private/config request so stalled getRemoteConfig calls reject and enter the
existing configuration-error path.
- Around line 266-267: Update the registration submit handler to set
isSubmitting and submitButton.disabled before awaiting
supabase.rpc('is_not_deleted', ...), preventing concurrent submissions. Reset
both flags when the RPC fails or returns !deleted so the user can retry, while
preserving the existing successful registration flow.
