React+Supabase RLS
Stack IntegrationReact + Supabase Row-Level Security
Row-Level Security turns your database into the authorization layer. Your React frontend calls Supabase directly — RLS ensures users can only see their own data.
Use Cases
- Multi-tenant SaaS where each customer sees only their records
- Per-user data isolation without a custom API layer
- Role-based access enforced at the DB
- Audit-trail tables that only admins can read
Implementation
RLS policies run in Postgres, not in your application code. JWT from Supabase Auth carries the user ID → RLS policy checks `auth.uid()` against a `user_id` column. No server-side API needed for most CRUD.
