Fix: Lovable App Data Disappears on Page Refresh
Quick Answer
Lovable likely generated frontend-only state management (React useState) without connecting it to Supabase. Tell Lovable: "Connect this form to Supabase. Create the necessary table and save data on submit. Load existing data on page load."

- !App works during the session but resets on reload
- !Data exists in the UI but isn't in the database
Step-by-Step Fix
Check if Supabase is connected
In Lovable, check if you see the Supabase integration icon in the toolbar. If not, click the Supabase button and connect your project first.
Ask Lovable to add persistence
Prompt: 'The data in [component name] is only stored in React state. Connect it to Supabase so it persists. Create a table called [name] with columns for [fields]. Save on form submit, load on page load.'
Verify in Supabase dashboard
After Lovable regenerates, go to your Supabase Dashboard > Table Editor. Check if the table exists and if data appears after submitting the form.
Check RLS policies
If the table exists but data isn't showing, check Authentication > Policies. Lovable usually creates policies automatically, but verify they allow SELECT for authenticated users.
Frequently Asked Questions
If you didn't mention data persistence in your original prompt, Lovable optimizes for simplicity and uses in-memory state. Always mention 'save to database' or 'persist data' in prompts that involve user data.
Yes. Just ask Lovable to connect specific components to Supabase. It will modify only the relevant files without rebuilding the entire app.
