Fix: Bolt App Loses All Data When Page Refreshes

Quick Answer

Bolt generates apps with in-memory state by default. Ask Bolt to add persistence: "Save all data to localStorage so it persists between page refreshes" (quick fix) or "Connect to Supabase for proper data persistence" (production fix).

Symptoms

  • !All user input disappears on page refresh
  • !App returns to initial state after reloading
  • !Form data and selections don't persist
  • !Todo items or saved content vanishes

Step-by-Step Fix

1

Add localStorage for quick persistence

Tell Bolt: 'Save the app state to localStorage whenever it changes. Load from localStorage on page load. Use JSON.stringify to save and JSON.parse to load.' This works for prototypes.

2

Connect Supabase for production

For real apps, tell Bolt: 'Connect to Supabase. Save all user data to the database. Load data on page load from Supabase instead of hardcoded defaults.'

3

Check if state is in React vs database

If data appears in the UI but disappears on refresh, it's stored in React state only. Any data that should survive a refresh needs external storage (localStorage, Supabase, or an API).

4

Test persistence after adding it

After Bolt adds persistence: 1) Add some data, 2) Refresh the page, 3) Verify data is still there. If not, check the browser console for errors.

Frequently Asked Questions

Bolt optimizes for speed — React state is fastest. Persistence requires a database or storage layer, which adds complexity. You need to explicitly request it.

localStorage for prototypes and single-user apps (data stays on one device). Supabase for production apps with user accounts (data syncs across devices and users).
