Once your Supabase database is ready, your Next.js application needs to retrieve the data. The exact approach depends on your application architecture.
Create a Supabase Client
Start by configuring the Supabase client using your project URL and appropriate key.
Query the Table
Suppose you have a posts table. Your application can request the records from Supabase.
Handle Loading
If data is being loaded on the client side, show a loading state. Don't leave users wondering whether the application is broken.
Handle Errors
Database requests can fail because of: Incorrect credentials Network problems Missing tables RLS policies Invalid queries
Show a useful fallback when something goes wrong.
Filter Data
Instead of retrieving everything, query only the records your page actually needs. For example, a page displaying one category doesn't need to download every record in the database.
Protect Private Data
For user-specific information, combine your queries with authentication and database policies. That way, the application isn't relying only on frontend filtering for security.
